SATA HDD in an external case over USB - 2 partitions

[Gary Stainburn]

I had to re-install windows on my laptop, and also wanted to try Fedora 13, so 
I came up with the idea of replacing the HDD and doing the installs onto 
that.

This has worked fine, and I now have a clean (but still flakey) WinXP install, 
and F13 dual booting fine.

I have now the old HDD in an external chassis connected via USB.

My problem is that neither OS will allow me access to either of the partitions 
on the old HDD. Both see the USB->SATA bridge, and see the HDD but neither 
will allow me access to the contents.

Windows just sits and smiles at me. Linux says it cannot access the drive.  
Can anyone help?

Well if /sys/block is empty, I'd say your  /dev is not getting populated.
What do you get from running mount?

I've just seen this exact problem with the exact same numbers.  The
drive is dead or dying.  I'm hoping mine comes back enough to grab the
data still on it.  When it works it works without error and passes short
smartctl tests.  I think the disk surfaces are probably okay and it's
the electronics that are almost gone.  If I find any sequence that seems
to get it initialized and working, albeit for a short time, I'll post.

Are you sure /dev/sdb exists?
Could it be /dev/sdc or sdd?
Do ls -l /dev/sdb
Also, sudo grep 'sd\.' /var/log/messages
to see how many drives were "probed" and attached.

If you're using F13, you can run palimpset (a.k.a. "Disk Utility" from 
your Applications>System Tools menu) to perform any disk maintenance. I 
could tell you how to activate the LVM via command line but palimpset is 
so pretty. ;)

By a process of elimination, unplugging, removing and reseating the HDD, 
rebooting etc., I have got the HDD working and am currently copying across 
the contents of the NTFS partition (/dev/sdb1).
Also auto-mounted was the boot partition (/dev/sdb2)
However, I can't get the main root partition to mount. As the fdisk shows, 
this was a LVM.

Can anyone please tell me how to mount the LVM so I can copy the contents 
across.

Dumb question - is your external case rated for a drive that large?
From the messages, it sounds like the drive is too big. Depending on
the electronics, there is a drive size limit to external cases.

Should it be sdb?  Try "fdisk -l" to list all the drives it finds.
