Comment 15 for bug 1368299

After formatting under 12.04, I didn't try to use the disk under 14.04 in a plain ext* format...
While running 12.04 I ran 'cryptsetup luksFormat', which ran successfully, I wrote a couple of files and read them. Then back in 14.04, similar to before, couldn't read the disk. I could mount it, but dmesg had the same msg as before which looked like a hardware issue:
[ 891.562667] end_request: critical target error, dev sdb, sector 0
[ 891.564060] end_request: critical target error, dev sdb, sector 97525840
