Hi I got new Kingston DataTraveller drive. I have repartitioned it in OS X than dumped and image of another flash drive on it. Few more times of the same but now it doesn't appear in any OS when I plug it in. Here is output of dmesg | tail in Linux:

[17472.104703] sd 12:0:0:0: [sdg] Attached SCSI removable disk

So it sees it a little bit and point it to /dev/sdg

If I mount it with mount /dev/sdg /media/usb:

mount: /dev/sdg: can't read superblock

If I try to fdisk it to see partitions (which it has none) with fdisk /dev/sdg I get this:

fdisk: unable to read /dev/sdg: Invalid argument

If I attempt to zero out the whole disk with dd if=/dev/zero of=/dev/sdg

dd: writing to ‘/dev/sdg’: No space left on device
1+0 records in
0+0 records out
0 bytes (0 B) copied, 0.000208433 s, 0.0 kB/s

I can't figure out how to trash entire disk and partition it again correctly. Any ideas?

P.S. Before this began I did manage to format it to ext2 in openSuSe but it threw a bunch of error which I don't remember any more. Windows also sees it as online but total size 0 bytes and won't let me format it.

To rule out a faulty usb hub or cable, try it on a different computer. If the error persists, the usb drive is likely to be dead.

Yeah I have tried on a number of different machines and ports. I am just surprised it worked briefly in the first place. –  Alex Apr 21 '13 at 15:36
    
Different OS, yes. I edited my answer. OP didn't mention a different computer. –  fuero Apr 21 '13 at 15:39
