Default hard drive disappeared with 8.10 upgrade

Hi,

I have a box with 2 hard drives, a 400G PATA and a 250G SATA. The recent
upgrade to 8.10 made a new install on the 250 that works fine but made the
400 disappear. Below is posted the last part of the dmesg file. I take it
that the drive needs a filesystem check,is that right?

[ 422.197183] attempt to access beyond end of device
[ 422.197203] sda2: rw=0, want=4, limit=2
[ 422.197212] EXT3-fs: unable to read superblock
[ 542.779742] kjournald starting. Commit interval 5 seconds
[ 542.779765] EXT3-fs warning: checktime reached, running e2fsck is
recommended
[ 542.780018] EXT3 FS on sda1, internal journal
[ 542.780028] EXT3-fs: mounted filesystem with ordered data mode.
[ 723.283816] attempt to access beyond end of device
[ 723.283840] sda2: rw=0, want=4, limit=2
[ 723.283849] EXT3-fs: unable to read superblock
[ 815.194637] attempt to access beyond end of device
[ 815.194656] sda2: rw=0, want=4, limit=2
[ 815.194664] EXT2-fs: unable to read superblock


Any and all ideas welcome.

Dave

Yes you have some problems on that Hard drive and you do need to run
e2fsck. I would start with reading the man page for e2fsck by opening a
terminal and typing man e2fsck and then read how to use this software.

From the warning messages it's not just that you need to do a file
system check. There may be something not right with the drive that has
disappeared, or it may be that it's disappearance is creating
"false-positive" drive-problem messages -- which could mean that it's
simply not mounted properly. Either way, the "attempt to access beyond
end of device" and "unable to read superblock" would make me nervous.
First a reboot into recovery mode and run the files system check. Then
a check of the /etc/fstab to see if both drives are being mounted
properly. I know recently when I pulled a 300gb SATA and replaced it
with a 750gb SATA there were boot time warning messages similar to
what your seeing until I corrected my /etc/fstab. If they persist
after both drives are correctly mounted, then you may have a real
hardware issue to deal with.
