unmountable partition

bizarrely I can read data from it and it mounts from an image... but still unable to mount actual drive:

root@SteveC:/tmp# dd if=/dev/sdb1 of=myfile bs=1M count=1000
1000+0 records in
1000+0 records out
1048576000 bytes (1.0 GB) copied, 41.6886 seconds, 25.2 MB/s

root@SteveC:/tmp# mkdir myloop

root@SteveC:/tmp# mount -t ext3 -o loop myfile myloop

root@SteveC:/tmp# ls myloop/
data lost+found steve

Thanks for this report.

Could you please paste your mount list here? Execute

mount

from the commandline and paste the results here.

Thanks

The output of the command "blkid" would be helpful too.

Thanks

As you can see in the blkids outpus, the partitions sda1 and sdb1 have the same UUID. This is why you get the error message when you try to mount sdb1 since it is already mounted as sda1.

We need more information why this might have happened. What did you do before the error occurred?

Do you use an lvm? How is the lvm configured?

Thanks

I haven't done anything, this is how it boots. :-(

No, never touched lvm.
