Don’t throw out that old hard drive from your computer! Yes, even if you got a fancy new solid state drive (SSD) or if your hard disk drive (HDD) finally gave up. Whether it’s functional or not, your old drive still has some cool uses.

What you should do depends on whether the hard drive is working or dead. But surprisingly, a functional old HDD has fewer uses than a dead one. So roll up your sleeves and check out some of these DIY projects to recycle, reuse, or repurpose an old hard drive.

1. Turn It Into a Portable Drive

Once you upgrade your laptop’s drive or run out of space on your PC, you have a functional HDD in your hands. Put it to use again by popping it into an external hard drive enclosure.

Depending on the drive and the enclosure, you’ll be able to use it with or without a power adapter. As a rule of thumb, power adapters are helpful for desktop (3.5-inch) hard drives, while adapters aren’t usually needed for laptop (2.5-inch) drives.

    I have an old Tandy (Radio Shack) 10 MB drive that is larger than most of todays computers, about the size of a Mid tower. At the time I bought it, seems like it was 3 or 4,000.00 Dollars!
    Since we were switching over from 5 1/2 inch floppys (which were REALLY floppy) it seemed like more storage than we could ever use.

    The problem if you sell a nonfunctional hard drive you won't be able to wipe it and it is likely that someone could fix it given an inclination for nefarious purposes.

    I have a 5Mb hard drive that was sold by Apple in 1981. It ran on the Apple // and Apple ///. The drive housing was about 18x8x4 inches and connected to the computer via a parallel cable. As far as I know the drive still works, but the computer doesn't.

    I have an old Seagate ST-225 that I use as a doorstop. I believe it was a whopping 20 MB.
    Then there is the old Micropolis 1373 SCSI drive. 80 MB and weighs a ton. When you started that baby up, it sounded like a jet taking off! It's not as old as the Seagate though.

    A few days ago, I raided a computer repair store for some junked old drives and motherboards. Looking through the HDDs, there were several 40Gb, a couple of 500Gb...and TWO 1Tb drives! When the hell did 1Tb drives become junk??

    I actually still have several 8gig hard drives, lol
    I would like to know what could be done with the "eye" that's in each drive. I save the steel rods from each, like the ones found in printers. These are perfectly straight and need heat to bend. I wanted to build a backyard foundry and these being great resistant would be great for fabricating the hinges on the furnace and the printer size ones for the handle on the crucible.
