Inaccessible USB-stick

Posted 14 January 2012 - 05:13 AM

Hello everyone,

I got an USB-stick, which I formatted with Ext2 (under Linux).
I used this as a file-storage for while.

Now, yesterday I was a bit hurried, so when I copied my files onto the device, I clicked at "Safely remove drive".
After clicking that I removed the USB-stick directly, so I got the message "Couldn't finish USB writing".

Now I'm getting into troubles with it.
When I put it into my PC (running under Ubuntu 10.10) the USB doesn't get mounted, and it's also not in a /dev/ list.
Also when I put it in my Windows 7 PC, the USB does not get recognized, not mounted and not seen.

I really don't know how to get back my access to the USB stick.

I hope someone could help me with this.

Thanks,

Sinned

Windows:
Right click on My Computer (or just Computer under 7)
Manage
Disc Management

From there you should be able to see the device even if it doesn't yet have volumes to mount.
Format it.

Have a nice day.

I've already tried that.

That's just the problem, it's completely inaccessible.
The USB-device is also not listed by Disc Management.

You could try a Macintosh. Sometimes going way away from the initial formating type helps.

Otherwise, buy a new one. Unless its 64gig or larger spending more than an hour on it is more than the wages spent on a new one.

Plug the drive into linux, open up a command prompt & type dmesg | tail & look for /dev/?da, where the question mark can represent any number of letters. Continue doing this for a least a minute or two. If you don't get any response, the drive is damaged &/or incompatible with the bus & not being picked up.

If you do see the device come up but cannot mount it, try mounting it with mount /dev/?da /media/(mount point) -o force.

I wish this had worked for me, but I'm sorry to say it didn't.
Unfortunately I have to say my USB-stick is permanently damaged.

In the future I'll be more attentive before pulling out an USB-stick.

Thank you all for your help,
Sinned

If it helps, I recently bought 3 flashdrives of 32gig each for $29 each after mail-in rebates at Frys electronics. (frys.com)
