USB pen drives crash when attempting to copy large files.

All of a sudden my pen drives keep crashing. One crashed while copying to and couldn’t be formatted so was replaced and now the other 3 I have will only copy small text files okay but will crash when I try to copy larger files and folders, i.e. movie files – copying only about 20% before crashing.

I have updated the USB drivers but the problem will not go away.

This makes my Pen drives practically useless for me if I want to watch a movie on my TV off of the Pen drive. Googling tells me that I’m not the only one with pen drive problems.

My system is Windows 7 Home Premium.

Your help would certainly be appreciated.

Thank you…Dave

    I am having this same problem with two new drives (4 GB PNY & an 8 GB HP), but not my old flash drive (2 GB Kingston). They all worked fine on another computer with Windows 7, too. Seems to be something with NVidia drivers, Win7 and having 4+ GB of RAM installed.

    If you or anyone else is still having this problem. I don't know if it will fix it, but try looking at this microsoft discussion http://social.technet.microsoft.com/Forums/en-US/w7itprohardware/thread/38f25c1d-de67-4c74-8845-2cd3a15d8e41/ for more info.

    1. "Could not find this item
    This is no longer located in Computer. Verify the item's location and try again"
    At that the USB also unmounts itself.
    2. In my experience, yes or very close to. This is the same on atleast one other windows 7 pc I have tried this with that's running a 32bit instead of my 64bit.
    3. Stuff copies off it about 20 times faster and doesn't crash.
    Any idea?

    I've got the same problem with a Kingston drive. It's a 16 gig one. I can't copy anything over a hundred meg or so. It works fine with XP and Linux and always has. It also takes forever to copy anything.

      1- What error messages do you get?

      2- When attempting to copy the same file, does it always stuck at the same place?

      3- Can you confirm that you're not able to copy both to and from the thumbdrive or is it only one way?

    What brand is your pendrive?

    Can you please tell me what is the size of those large files are you referring to? How big are they? For instance, certain file system like FAT doesn't support files larger then 4GBs. In such cases formatting the thumbdrive with NTFS does the trick.
