Thank you for taking the time to report this crash and helping to make Ubuntu better. This particular crash has already been reported and is a duplicate of bug #756297, so is being marked as such.

Additionally, any further discussion regarding the bug should occur in the other report. Please continue to report any other bugs you may find.

The duplicate report is talking about a FAT partition. This disk contains ext4 and NTFS partitions.

[Colin Watson (cjwatson)]

Do you still have the original crash file, or can you reproduce this? The retracer has deleted it.

What filesystem is on /dev/sdb1? Is it small enough (and clean of sensitive information) that I could get a copy of it?

[Brad Heap (nzv8fan)]

The bug report was filed via apport - I am not sure if it saves the crash files somewhere.

I don't have sdb only sda... here is the result of fdisk -l
