I had one Transcend 4GB USB stick formatted to NTFS and was working fine. Today I inserted this disk into a DVD player, and it was saying, "loading". After a long time, noting happened, and it seemed that the stick (NTFS) is not recognized by it. I took out the stick and tried to reformat to FAT32. But the stick is not being recognized in my machine (Ubuntu 12.04).

I tried the advices from USB drive not recognized after Erase Disk, without any success.

When I tried Disk Utility, the stick is indicated as a generic device. See image,

Disk Utility Main Screen]![enter image description here

Formatting this device fails, saying, No medium found. Again see image,

No Medium]![enter image description here

gparted does not even list this device.

The same thing happens for fdisk. It is not listed there.

Have I totally lost this stick? What should I do?
