Pen Drive showing 0B of data and also shown as unreadable in disk management.

It happened after I was copying a Windows 7 ISO file onto my pen drive when the message appeared "Windows was unable to save all the data for the file Windows 7.iso. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere."
After that my pen drive turned useless. I tried connecting it to my PC and there too it showed 0B as space. I tried some fixes online by using attribute command in cmd but that didn't work as it showed that my pen drive's path was not found. This has been bugging me quite a lot. I tried allocating space but failed to do so. Please help me out. I will also provide further information if needed.

  1. Sounds to me like the pen drive has failed.

    How can a simple copy/paste function can ruin a pen drive? Is there anyway at all I can fix it? I don't need the data.
    Also, I found out that the pen drive has turned RAW. Please help me out.

    I doubt the act of copying caused the drive to fail, it just happened to fail while it was copying. It's like having rain start while you are at a party, would you say "how can me being at a party cause this rain?". Can you see the disk in drive manager? What happens when you try to create a new partition? If it fails, test it in another computer. If that also does not work, replace the drive.
  4. It's simple. The flash drive is low quality. It happened to me several times with various pendrives from ma y manufacturers. Believe me this is nothing unusual. How much did it cost? When did you buy it? If it's still in warranty then just return it. There is really no point trying to fix it! Once I got a flash drive and it stopped working exactly during first use in a computer!
