I’ve experianced this issue a few days ago. My pen drive stopped working, and any disk manager I use displays the partition as RAW. The same, with any computer or disk utility, it refuses to format. I get a rapid blinking light, and a device error (which displays a different error every time). I tried on Ubuntu’s Live CD and Windows 7. On other computers I’ve tried with Vista, XP, OS X, and the Live CD. The same result happens. I’ve also tried the HP utility and it still refuses to work. The drive cannot be more than 7 months old. This happened before but I forgot what I did to fix it.
Any help is appriciated.
