Can an unmountable drive be saved?


I have a 2 terabyte USB drive with several partitions, it is formatted, populated and had worked, now it won't mount. Sometimes it automounts but as the file manager tries to list the files it vanishes. I've tried several different linux distributions and none can reliably mount it. Gparted was able to find it once and then failed. I imagine there are some bad blocks that cannot be reliably read causing the inconsistent behavior.

Are there any Linux tools that can help?

I gave a plus to testdisk but I also suspect that there is some other issue with this device. I'd remove the drive from the enclosure and try a different one or inside a computer.

Interesting, TESTDISK can talk to the HDD.
I'm still learning to use Linux so I opted to use the WINDOWS version of the application. I haven't figured out the app yet, just feeling my way around but I'm encourage since it is communicating.

Umm the Windows version of Testdisk is actually a cygwyn compiled/ported Linux program. It works exactly the same way as the Linux one.
Also to check the dist for internal errors you could use gsmartcontrol. But for this the enclosure's firmware has to support SMART.
As jefro said, it would be a good idea to pull out the actual drive and connect it internally via sata cable. Sometimes the enclosures/cables cause issues like this.

It could also be the USB bus. It might work well on completely different hardware. I had that once, although it was a laptop that had had a failed fan for over a year.

When it fails, does it's existance show up in /proc/partitions?

I had the same problem with a usb drive, it turned out to be a broken wire in the data cable, sometimes there would be a gap & I would 'lose' the drive from my system; try a different cable.
