5 Warning Signs Your SSD Is About to Break Down and Fail

Mihir Patkar Updated 09-12-2019

Solid state drives (SSDs) are faster, more stable, and consume less power than traditional Hard Disk Drives (HDDs). But SSDs aren’t flawless, and can fail before their expected life span of five to seven years.


It’s best to be prepared for an eventual failure. If you know how to tell if an SSD is failing and how to protect yourself, you won’t be a victim of SSD problems.

How Do SSDs Fail?

Unlike in HDDs, there are no physical moving platters in SSDs, so it’s immune from old hard disk issues. However, while the storage component itself isn’t susceptible to mechanical failure, other components are.

SSDs require a capacitor and power supplies, which are vulnerable to malfunctions—especially in the case of a power surge or a power failure. In fact, in the case of a power failure, SSDs have been known to corrupt existing data too, even if the drive itself hasn’t failed completely.

The other possible problem with SSDs is that they have limited read/write cycles, an issue that exists with all kinds of flash memory.

Now, all that being said, SSDs should last many years on average Hard Drives, SSDs, Flash Drives: How Long Will Your Storage Media Last? How long will hard drives, SSDs, flash drives continue to work, and how long will they store your data if you use them for archiving? Read More  so you shouldn’t worry or be paranoid. In fact, if you bought an SSD in the last couple of years, then research has shown that new SSDs are less susceptible to these read/write problems than old ones.


Either way, the read/write cycle will affect whether you can write to your SSD. Since you’ll still be able to read your data, it can all be retrieved. However, you’ll still want to know when it is nearing the end of its life so that you can upgrade.

Here are the important symptoms to be aware of.

How to Check the Health of an SSD

Crystal Disk Mark for Windows can check if your SSD is failing or has problems

The incessant whirring or ticking of an HDD is an easy way to know if it’s failing. However, unlike HDDs, SSDs won’t make a noise to tell you that something is going wrong.


The most hassle-free and reliable way to find out if your drive is running smoothly is to install software which checks it and silently monitors it for flaws. Windows users might want to try CrystalDiskMark while macOS users can take a look at Smart Reporter Lite.

Apart from that, here are some signs to watch out for, symptoms of a bad drive, and what you can do about it.

1. Errors Involving Bad Blocks

Hard Disk Sentinel checks and warns for Bad Blocks on SSD


Much like “bad sectors” on HDDs, there are “bad blocks” on SSDs. This is typically a scenario where the computer attempts to read or save a file, but it takes an unusually long time and ends in failure, so the system eventually gives up with an error message.

The common symptoms of bad blocks are:

  1. A file cannot be read or written to the hard drive.
  2. Your PC/file system needs to be repaired.
  3. Active applications often freeze up and crash.
  4. Frequent errors while moving files.
  5. Generally running slow, especially while accessing large files.

In case you see any of these symptoms, the best idea is to run Crystal Disk Mark or Smart Reporter Lite or Hard Disk Sentinel and check if there are any physical problems with your drive. If there are, then back up your files right away and start shopping for a replacement SSD.

2. Files Cannot Be Read or Written

One Symptom of Failing SSD is when files can't be written or read

There are two ways in which a bad block can affect your files:

  1. The system detects the bad block while writing data to the drive and thus refuses to write data.
  2. The system detects the bad block after the data has been written and thus refuses to read that data.

In the first scenario, your data has never been written, so it isn’t corrupted. Usually, the system will resolve it automatically. In case it doesn’t, you can probably fix this by attempting to save the file in a different location, or by copying it to the cloud, restarting your computer, and then saving it back to your drive.

In the second scenario, unfortunately, your data can’t be easily retrieved. You can try some methods to recover data from a failed SSD, but don’t get your hopes up. Bad blocks usually mean that whatever data contained on those blocks is lost for good.

3. The File System Needs Repair

When Windows or Mac tells you to repair your file system to reboot, that is a sign of a failing SSD

Ever seen an error message like this pop up on your screen, on either Windows or macOS? Sometimes this can happen simply because of not shutting down your computer properly. However, other times, it can be a sign of your SSD developing bad blocks or a problem in the connector port.

Thankfully, the resolution is easy. Windows, macOS, and Linux come with built-in with repair tools for a corrupt file system. Upon such an error, each OS will prompt you to run their respective tool, so follow the steps and repair the file system.

There is a chance of losing some data in this process and recovering it might be difficult. It’s yet another good reason to back up all your files periodically.

4. Frequent Crashes During Boot

If your computer often crashes while booting up, that is a sign of a failing SSD

If your PC is crashing during the boot process but works fine after hitting the reset button a couple of times, then your drive is likely to blame. It might be a bad block or the sign of a dying drive, so it’s best to back up your data before you lose any of it.

To test whether it’s the drive, download and run one of the aforementioned diagnostic tools. If you have backed up your data, you can also try formatting your drive and reinstalling the OS.

5. Your Drive Becomes Read-Only

If your drive says it has become read-only, that means the SSD has bad sectors. Backup data immediately

It’s not that common, but some users have experienced this one. Your SSD might refuse to let you perform any operations that require it to write data to disk. However, it can still work in read-only mode. For all intents and purposes, the drive appears dead, but surprise, your data can still be recovered!

Before you throw away an SSD that you think has failed, try connecting it as an external hard drive or a secondary hard drive to another computer. Make sure you don’t boot the operating system from the SSD; you need to use the computer’s main drive for that.

In case the SSD is still functioning in read-only mode, you can retrieve all your files before securely erasing the SSD How to Securely Erase Your SSD Without Destroying It SSDs can only be written to a limited number of times. Then how can you securely erase your SSD? Here's what you need to know! Read More .

How to Extend the Life of Your SSDs

If your SSD is on the verge of failure, or if you’ve owned one for over five years, then the safest thing to do would be to start shopping for a replacement. Meanwhile, you can do a few things to extend its lifespan till you get a replacement:

  1. Avoid extreme temperatures from affecting the drive. Ensure good cooling in your PC.
  2. Avoid power outages and any electric fluctuations.
  3. Free up some extra space on your SSD so it can move data from bad blocks.

Learn more about what you can do to protect your SSD and extend its lifespan. And when you’re looking for a replacement SSD, be sure to consider an M.2 SSD. Here are the pros and cons of an M.2 SSD and how you can install one.

    "Avoid power outages"
    Great idea. Am I to build a power plant in my backyard?
    Or just send a bill for an SSD replacement to my electricity provider? In last 3 months I had so many outages that my SSD now fails to even boot Windows 80% of the time, and even when it boots, there's still high probability it will just freeze totally until I hard reset the thing.

    My laptop crashed. I pulled the SSD and heard it rattle. Rattle? I opened the case and found that it enclosed a small card with the chips onboard. The card was supposed to be screwed to the case with four screws. One screw was missing and one screw was floating loose, which obviously shorted the board. I was never anticipating anything like that.

    If my SSD were to fail, I would have to go back to a spinning drive. There aren't many new SSD II flash drives for sale. No, I will not buy a new PC just so I can use an SSD III drive. My current PC still works well.

      I manage an office with 11 workstations. Replacing a 4 y/o SSD with an HDD right now. BUT, we've also had to replace 5-7 y/o HHDS (WD Blacks), so even those aren't the tanks they once were. Maybe it has something to do with speed -can't have that and durability together on an HDD? BTW, our SSD went from slow to no boot in less than a week. Its death was very fast. Get ready to swap the minute you even !suspect! an issue.

      SSD III (or SATA 3) drives are backwards compatible with SSD II (SATA 2). In that I mean that you can use an SSD III (SATA 3) drive in computers that have SSD II (SATA 2) or even SSD I (SATA 1) controllers. They will just be limited to the speeds of the computer's controller. Otherwise they will function just fine. I regularly install SATA 3 SSDs in older SATA 2 computers.

    This is my encounter with Samsung SSD 850 EVO 500GB. Was experiencing frequent bootup failure and thought there was something wrong with my desktop. sent for $85 repair which was just a reinstall of my winsdows 10. A few days later, the same problem persists and by then it cannot even be booted up.
    Removed the SSD and plucked into another PC as USB drive. Sometimes can detect, sometimes cannot be detected by the PC. I try to scan for system errors too. No use even after the scan. It also cause my PC to hang several times (doesn't know why) . I keep trying at different intervals frantically and slowly managed to move my files safely out! Whew! What a relief. Then I tried to reformat, can't.
    I reinstall back to my original PC to reinstall. Have tried at least more than 10 times and wasted so much of my times that I have totally given up. I left the computer overnight to format etc etc which is a complete waste of time.
    I did some stupid thing earlier which is to shut my power off before the PC really shuts down thinking that since there is no moving parts, it should not matter as it wont crash.

    Acer laptop developed startup problems/failure after over heating and switching off on a 43degree day, problem not loading properly after log in, black screen with mouse and when hitting windows key task bar would appear and start menu would open, still no desktop or icons and no programs would run, restart once or twice and then would run fine, complete failure about 3 weeks later, blue box at startup "default boot device missing or failed insert recovery media ..."

    I bought a cheap western digital SSD on Amazon. No matter what OS I installed on there it would freeze randomly. Was really sad as this was my first SSD and I no longer really trust the technology. I think I'll stick to spinning platters for a few more years I've never had a desktop HDD drive die and the only reason my laptop HDDs ever die is foolishly moving the laptop before shutting it down.

    My ASUS laptop suddenly got the BSOD one day. About five minutes after I booted up every time the computer either froze completely or Blue screened. I suspected SSD failure but I wasn't sure. I tried reinstalling several times but my computer crashed at some point after windows setup copied files to the drive. Once I tried reinstalling windows 3 times it wouldn't work even reach the setup screen. Bootable linux distros didn't find the drive and I was certain by then my ssd had failed. I bought a new ssd, a Samsung one of the same capacity. When I reinstalled windows it ran a dream. My computer failed less than a year after I bought it. They put some shit obscure and unreliable brand on SSDs. Hope this doesn't happen to anyone else as it was a nightmare having my SSD fail.

    My Samsung 840 almost never boots right on first, second try, it never has, despite having had win 7, 8 and 10 on it. Sometimes, it can take 5 or 6 tries, from a simple restart to full power-down of the computer.

    My Sumsung 250gb eco drive seems to have slown down in about 3 months.
    I belive it is due to me not turning off Nortons dumb out of date auto defragmenter.
    I am sure the Samsung is a good drive if you look after it carefully...

    I recently put together a system 6-7 months ago. I booted it up and began to surf the internet. Within 5 minutes, the system slowed to a crawl and my mouse froze. Total crash within 5 minutes, no warning signs at all. Up until that time, the system was running as smooth as silk. After the crash the system would not boot at all and asked to boot from another source like a USB drive. Bios did not recognize the SSD at all. Swapped cables, then drives. Then I could load windows to a different drive. The system booted up and is running fine now. However, the system will hang if I add the SSD to the computer. The SSD is still under warranty and will get it replaced. Windows disk management tool has seen the drive but it won't/can't do anything with it. Will be considering a HDD replacement from microcenter.

    I recently ran a Windows update, nothing unusual about that, but when my System rebooted. It never came backup. Finley had to Create another boot drive from scratch. Good news is Windows Updater creates a folder called Windows.old, and all my data is in there. But the SSD drive that failed will not allow me to create my user Home fold any more. The drive is a newer Samsung 850 EVO 500gb drive (3 Month old).

    My 5+ year old OCZ Vertex 3 started having issues recently with system freezing for several seconds (or longer, sometimes up to a minute) making my PC hard to use. I've tried to do a 1:1 sector dump of the SSD and got read errors.
    Fortunately, file based backup has succeeded without errors so hopefully I will not have to reinstall my OS.
    This drive has over 10 TB of writes on it. No errors on reported SMART other than drive remaining life dropping to 99.

    I will be moving my OS drive to an HDD until I get a replacement SSD.

    Ok, get ready for this one. A sailor can say what I've been saying. I built a custom PC about 7 years ago now, give or take. Started with a Samsung SSD 120 GB works great to this day but I needed a bigger one. I have a 2TB HDD for storage but 120 wasn't cutting it for Windows, office and all the files for work that needed to be safe from failure. So updated to a Samsung EVO 850 250 GB SSD. Score so fast....6 months later it shit the bed. Total failure, no notice. 100% loss. So I did what any PC builder would do I went to bestbuy (MicroCenter is way better) and got myself another Samsung but this was an EVO 850 500GB, more space right how could I lose. 3 1/2 months later, could not boot OS. data saved S.M.A.R.T. says it's a old hard drive with pre failure going on. ARE YOU KIDDING ME! Now I am trying a Samsung EVO 860 500GB, not pro. wish me luck. Is there a better SSD out there, I know pro would be but that was not around when I got the other SSD's. Reviews say, almost all of them Samsung is the good one.

    RECAP time to failure all Samsung SSD's, 120gb=7+ years, 240gb=6months, 500gb=3.5 months. Think what Qbert would say, #$@! PC runs for about 10 to 12 hours a day, 5 to 6 days a week. yes I game on it. Games are stored on HDD

    PC build, Corsair 400r case, amd fx8320, 100I liquid cooler, XFX rx 480 8gb, 32 gb system ram, OCZ Fatal1ty 750W power supply, 2 DVD drives and asrock extreme 4 mobo, five case fans, 2 in front, 1 in the back and 2 on top.

    my SSD is failing, and windows is popping up messages every now and then "Windows detected a hard disk problem" and suggest me to backup immediately.
    Your app in fact reports critical status due to "Raw Read Error Rate" at "1".

    It will be the 2nd such SSD in 2 years.

    When the SSD dies it is catastrophic and no warning at all ---that is what I learned from hard experience. An hdd will show some symptom so my rule of thumb is to image the SSD to a HDD for redundancy. I just don't trust SSD for now but still like it for speed reason. Since HD are cheaper I use it for archiving . For important document stuff I store it in the cloud base.
    Backup anything you think is important so that you don't feel bad when it crash.

    My Compaq Seine all in one is seven years old but I thought I'd give it a boost and replace the old 160gb drive with a 128gb Patriot Spark ssd unit. Change for change sake? Anyway the new ssd has only lasted four months and a check disk shows most of it is now unreadable.....
    Back to the original drive I guess.

    I've had an HP All-in-One with a 2TB SSD for about 6 months. Presently, it's in the shop because it fails to boot from the SSD, and has no HDD. I get a "S.M.A.R.T." warning that there's failure iminent, but when I go on, allowing it to attempt to boot, it fails because it "thinks" it has no HDD.

    I recommend daily full image backup, including all app's and the OS, and multiple virus scans each day.

    I'm presently looking for an appropriate way to accomplish that in a single operation. That may not work easily under Windows10, which seems to interfere with everything useful.

    I believe I just lost my 480 gig SSD. It started about 3 weeks ago and would not boot. It was bought at the beginning of February. This is the middle of March. I believe it was the boot sector that was corrupted. It was easy to recover because I had a 750 gig HDD backup that I clone often. Earlier this week the SSD would not boot again. I again cloned it from my HDD. I went and did some work on my SSD and wanted to make sure I kept a copy of the work I had completed, so I cloned the work onto my HDD. After cloning, the SSD would not boot again. I wondered if my worst fears would happen. I tried to boot off of my HHD and now it would not boot. I cloned a fatal boot problem to my HDD. Now I do not have any drive to boot from. Taking two days of using the command prompt using "bootrec" and 10 other commands, I was able to copy boot files from an old Win 10 laptop HDD I had, to the HDD in the machine. I had a usb dock to link the drives via computer. The problem was, it took me about 15-20 tries before I had the HDD back up and running. I ordered a new WD 500 gig SSD to replace the "bad" SSD. I did not buy one from the same manufacture, which I believe was Mushkin. It took a while but I did learn a lot. I also learned not to clone from a failing SSD or HDD. I also have two laptops with IDE SSD's and they work flawlessly and fast for IDE.

    Just RMAed a samsung 950 pro... couple days ago i tried installing gta 5 on steam. During allocating disk space, before the download even began, i got bsod critical process died. After 2 days of straight troubleshooting, i determined that not only was the ssd in a read only raw filesystem state, preventing windows recovery and reinstillation processes, but the drive would always show up for a split second, but upon attempting format, delete partition, chkdsk, sfc /scannow, any and all DISKPART functions, bootrec cmds, or any drive interaction at all, the drive would vanish from existance preventing any function. Troubleshooted BIOS, fiddled with secure boot and others, no effect. Drive is on its way back, running memtest86 and such to try and rule out other components.

    Its a m.2 ssd, i wanted to try to plug it somewhere else but i had no ability. Funny thing is local computer repair places, even geeksquad told me they cant plug this type of drive in. I suppose if i had an adapter...but we will see what happens with the RMA.

    My worst fear is a faulty m.2 port on the motherboard and not it being failure of the drive.

All of a sudden it had errors booting into windows, I couldn't restore windows and didn't want to loose the data on it so buying a new SSD to reinstall windows tomorrow. Taken 7 hours to fully fully check it.

    If you are having regular SSD another brand. I work in a corporate environment and during our pilot rollout of SSD's one batch from a vendor who will not be named, every device failed within 3 months. The vendor we finally settled on has had a great track record. Some of our SSD's are now over 6 years old. As this is a corporate setting they will either be aged out via upgrade cycle or attrition. We did get a batch from this vendor with a very nasty firmware flaw that mimed a catastrophic fail, but a firmware update and it was back to normal. Bottom line is ymmv, but if you are getting repeat failures in short order, rethink your next purchase.

    Sometimes, SSDs will fail "out of the box" as my appears to be doing. Fewer than 2 weeks ago, (11-Oct-16) I got the 120 GB drive as a replacement for the HDD that crashed in my (dare I say it) now 8 year old WIN 7 Pro machine. It booted the OS just dandy and was humming along. I used it to access the previous crashed HDD to retrieve its data-(surprisingly so!) Then, about 7 days into its life with me, the machine tells me that the G: drive (the crashed previous HDD that I retrieved some data from and left hooked up) needs File Checking. OK, so this REALLY confirms that HDD crashed. So, the new SSD now doesn't want to allow me to sign in, it won't boot without the WIN 7 media disk and when I did get logged in, it erased ALL the emails in the Mozilla Thunderbird inbox. Then, it started NOT putting the computer to sleep; power profiles (any of them) can't be altered and it decided to change the look of WIN 7 Pro to that of the "classic WIN 98"-slate grey with right angle corners on the start button, for instance. It also doesn't seem to want to allow me to make a fresh install of WIN 7 Pro. There have been other error-type messages than lead me to conclude believe that in all of this, the new SSD failed out of the box and something from the failed previous HDD that failed might have caused this issue. Either way, it appears it's time to buy another new SSD.

      If you install windows on a computer with a new hard drive and leave the old one still attached then the boot sector could happen to go onto the old hard drive so that was a big mistake. always remove the old hard drive while making a clean install to insure everything goes to the same drive. I also found out the hard way.

      I am pretty sure it was not your SSD causing these problems, i do not know how you got to these issues since you did not explain what you did step by step but i am sure its not caused by the hard drive.

    Five years?? I've had this laptop approximately 5 years and have replaced the SSD at least 3 times, or is it 4? I keep my data on a regular HD and it just keeps going fine. Seems like about every 8 to 14 months they hit their read/write limit and that's it. My recommendation is to keep a cloned backup drive or you end up not only having to reinstall all your software, but also buying a new OS.

    I have two SSDs in my gaming computer and one just failed due to Microsoft's Anniversary Update (or at least that's who I'm blaming). Thankfully it's not the one the OS is on, but the one all my Steam games is on. Yeah, I'll have to reinstall my games but I think the save points in them are in My Documents on my OS drive. They are both Samsung EVO drives. I'm still running the scan on it (started it last night and this morning it was 53% done when I left for work) and I already ordered another one. Price/performance trade-off meant getting another EVO. Not worth another $70 for the pro or more for a different model. I have all my essential docs & images on a server.

    I'm having an issue where my computer restarts (can't confirm the restart thing) and comes up with the unable to find Boot Device error.

    It has happened a number of times now, and usually happens when computer is not in use.

    Oddly, Restart will not clear the error but a Reboot will.

    My SSD tests fine with in house software & Windows Event Viewer is no help.

    I thought it might have been my old PSU, which blew up a couple weeks ago, but I am still getting it as it just happened this morning.

    Since it is happening when it would be using the least amount of power, I cannot see it being a PSU Problem.

    I also switched my BIOS, I have a DUAL BIOS, but that doesn't seem to have helped

    Any Ideas?

      I'm having the same problem, but I think the guy is right about the SSD failing. I have a Samsung 840 EVO 256gb. It reports ok in the Magician software, but still....symptoms are very similar. I even got the same blue screen today in the middle of watching a movie.

    Smart Reporter Lite appears to be discontinued.

    you mean crystal disk info ?
    " In case you see any of these symptoms, the best idea is to run Crystal Disk Mark or Smart Reporter Lite or Hard Disk Sentinel "

    CrystalDiskMark doesn't read any SMART data or does anything to maintain your SSD - all it can do is measure the performance.
    You want CrytalDiskInfo to check the SMART data of your drive (it also says so in the link you refer to).

    Well ever since I've switched to Windows 10 I have constant crashes and have had to do clean installs 7 times now (did one two days ago after changing up some ram when it went nuts).

    So it may genuinely be my hdd that's the problem and not windows 10...more money to fork out....sigh...

    The SSD is a strange animal.

    On the same PC I have two SSD Samsung 256 GB.

    A 840 Pro bought in September 2013 and a 850 Pro bought in September 2015 (the two are not EVO).

    The first suffered from numerous power failures, but his State of health is 97% and has no bad sector.

    The second suffered only a power failure, is at 99% and has a bad sector that has been remapped. (HD Sentinel says that he has no concern to have at this stage and it is much too early to involve the warranty)

    Yet the 850 Pro is theoretically more robust since it is guaranteed 10 years against 5 for the 840 Pro.

    I Have Never Seen A Physical SSD, But By The First Comment I Do Not See Any Big Difference From Crappy FlashDrives With Corrupted Files - And I Have Seen A Lot Of Them.

    Most Storage Devices Without Moving Parts Are Crap - And SSDs Are Really Expensive Crap.

    I Rather Have An HDD That Is Suddenly Forever Unreadable, Than A Supposedly Working SSD With Hidden Corrupted Files.

    I Will Never Trade Reliability For Speed, Period.

      They arent expensive that much anymore. You can find 120GB MLC disk for 35-40USD
      Yes they aren't reliable. But HDD + SSD combo is fast, reliable and cheap.

    Since you did not mention any SSD monitoring software for Linux, does that mean that SSDs used on a Linux system do not fail? :-)

      You'd probably use something like SMARTMonTools to monitor the drive's SMART status on Linux.

    Had my main drive — an SSD — fail last month. No real warning signs, although I guess my OS had been lagging more and more, though it was a pretty gradual change. Managed to retrieve much of the data via recovery software, but some of the files in my documents folder were irretrievably damaged. What's more, apparently those files got corrupted much earlier and so although I was backing up that folder regularly, the backups got corrupted, too, as the program I was using apparently decided the corrupted versions were newer and should replace the older, un-corrupted ones.

    My advice: back up like crazy. Save some early backups, too — ones that you know are good. And once you've gotten your OS tweaked just the way you want it, do a disk image of the entire drive, so you don't have to start from scratch reinstalling everything and restoring all the default settings. Although you'll want to keep a backup of your most crucial stuff on an external drive or disc, it's not a bad idea to also back up to the cloud, since most cloud servers have redundant backups. Those external backups may fail, but presumably, your cloud backups should remain viable for as long as you keep them there.

      I agree with most of your recommendations, but am posting to point out the really low (intellectually low) level of answers available on the Web to the question 'How (=in what way) do SSDs fail?'.
      A strategy of 'take lots of backups' is no defence against unrecognised corruptions - it just gives you a false sense of security and lots of copies of duff files to sort through while regretting at leisure.
