I was writing a file of 4GB on my flash drive. The process made the whole system slow so I restarted system and found that the drive works no longer.

I Don't need to recover it's contents I only want to make it working once more

wnen Gparted is first executed it shows dialog box with

input/output error during read on /dev/sdd

I click on ignore. And when I click On information it shows following

Model:    JetFlash Transcend 16GB
Size:     14.71 GiB
Path:     /dev/sdd

Partitioin Table :unrecognized
Heads:            255
Sectors :          63
...

When I try to create new partitioin table it again alerts input/output error during read on /dev/sdd

When The drive is inserted in usb port the system log is:

    Try dd if=/dev/zero of=/dev/sdd. Maybe you have to replace it... – davidbaumann Feb 7 '15 at 20:50
  • dd if=/dev/zero of=/dev/sdd again gives input/output error on /dev/sdd – Sudip Bhattarai Feb 8 '15 at 3:51
  • The drive had two partitions: ext for bootabe ubuntu and ntfs for other data,which I made 2 hours before and was working perfectly fine. And when i was copying files to ntfs partitoin,this happened.does making partition have anything to do with this? – Sudip Bhattarai Feb 8 '15 at 3:54

If even

dd if=/dev/zero of=/dev/sdd

is giving you an I/O error, your USB stick is broken: throw it away and buy a new one.

Sorry to be the harbinger of bad news. :-(

  • Then why does gparted shows it's name JetFlash Transcend 16 GB and it's size 14.71 GB? – Sudip Bhattarai Feb 10 '15 at 16:29
  • Because the master boot record is still readable... The unrecoverable error is after that. If you have no money to buy a new one, leave me a comment and you might be able to recover it, but in my experience you'll end up losing data as the problem is only going to get worse and worse. – Fabby Feb 10 '15 at 16:31
