I was using it to back up two laptops: an IBM ThinkPad running Xubuntu 11.10 with a Qimo session, and an LG R200 running Ubuntu 11.10.
I had previously backed-up both computers, several times using Deja Dup, into separate folders onto the Seagate hard drive. At one point, I copied some files directly into another folder on the Seagate, from the R200 without using Deja Dup.
I was in the process of copying some of these files again and got an error message that there was something wrong with a file and the Seagate hard drive is blocked. I tried to do a regular back up using Deja Dup and got a similar error message. The same when I tried to back up the ThinkPad.
How can I get my Seagate 2TB Expansion Drive to work again?
The error message was this or similar:
Error mounting: mount exited with exit code 13: $MFTMirr does not match $MFT (record 0). Failed to mount '/dev/sdb1': Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details.
