"...it has written on it". I presume it's used then, right?
Based on your description, it doesn't sound good so far. But let's try performing a "Check Disk" and see if we can't just fix that bugger:
- Open "Command Prompt"
- Type "chkdsk H: /F /X" (without the quotes), then hit Enter.
NOTE: If notified that it needs formatting, go ahead and attempt that, then perform the check disk if the format is successful.
Does this procedure execute without any read/recognize related errors?
- If YES, do it once again, but this time replace the /F switch with /R. This will perform a more thorough disk surface check in order to protectively lock out any bad (unreadable/unwritable) blocks it may find.
- If NO, you in all likelihood have a very small piece of toast. If it's new, return to the vendor you purchased it from. There ARE utilities that can ATTEMPT to revive/correct it, but I personally would never have full confidence in it's read/write reliability. And more than that, it simply isn't worth it for a device you can replace with a brand new (and even mo' better) one for around $10 or less.
Good luck and please post back if you have any further questions, and/or to just let me know how things worked out.
