I've got a USB drive here, that somebody asked to try and fix. When inserting it, it shows up in explorer, but when I double click it I get a message saying "Please insert a disk into drive H:". So I went to disk management, to see if it was correctly formatted. It doesn't show up in the upper pane, and in the lower pane it tells me there is no medium in H:.

After this I used chkdsk: the path is invalid. Then I tried TestDisk, which is supposed to look at raw data, and this can't even find the disk.

So I'm assuming the drive is dead, even though its LED is burning. But I was wondering if there might be something else I could try?

This system is Windows 7 Ultimate 64bit by the way.

(I'm translating things from a Dutch install, so some names might be wrong)
