Repairing a usb Hard drive


I have a some usb hard disks I would like to repair. I think they have all damage to their fat table and I am not very comfortable with the process.

The terra-byte drive (Highest repair priority) when I plug it in to my Fedora Box, I get the following output (It reppeats many times) in /var/log/messages:

May 16 09:05:36 draco kernel: [126465.105051] usb 1-2: new high-speed USB device number 54 using ehci_hcd
May 16 09:05:36 draco kernel: [126465.168267] hub 1-0:1.0: unable to enumerate USB device on port 2

Most articles I have seen on doing this mention using SDBn port and I see nothiing like that. So, what parameter in this case would I hand to testdisk?

Have you tried removing the hdd from the usb caddy,
& accessing it directly ??.

They are often a stata hdd - & can by accessed as a 'normal' drive . . . .

are you going to repair the USB HDDs (which means hardware) or the filesystem on them (which would be a software issue)?
The latter would be easy: Just re-format them, and you're done.

"Tera", not "terra". It has nothing to do with Earth (latin "terra").

That looks bad - obviously you really have a hardware problem here: Your USB host controller sees that there's a new device connected, but can't identify it. Very probably, the USB/SATA bridge chip inside the external enclosure is half-dead.
In that case you have a fair chance of continuing to use the HDD: Just get yourself another USB/SATA enclosure (should be available at any computer store, costs about the same as an up-to-date DVD movie), and swap the HDD into the new one.

Thanks for the info. Probably not worth the investment. I am just as well off to watch for sales, you can get a Tera Drive for under $100 bucks. It basically comes down to do I buy retreads for $30 or new ones for $90.


Thx anyway.

hmm, and that's better than purchasing a new enclosure with a USB/SATA bridge for, say, $20 and just putting the HDD into it?
