having the same issue <snip 2> with a WD (Western Digital)  drive (My
Book Essential Edition 2.0 WD10000H1U-00)

Was using BackupPC to use the drive for backup's and it failed, its ironoc in a 
sad way LOL :) 
it failed at about 68GB on the drive, so I amd gettign the impression that this 
could be coming that we are not handeling the size or the sence code coming 
back from the drive for this, at the 68 GB stage. done a cat /dev/sdc1 just to 
see if I could spin the disk and it seems to spin, though the beauty of putty 
is that I couldn't exit from it ! :)


talked to WD and WD are claming that linux is not supported ( Whats new!!)  
Problem here is that we are not getting any sense codes, so cannot even see 
what the problem is.
Can we add a Debug flag on to the system  ? 

also using LVM, I am able to see the disk through fdisk -l  but fsck is
failing at 66.1% with just a hang. judging by
https://bugs.launchpad.net/ubuntu/+bug/460831 its looks to be the same
issue, and ubuntu is not handling the scsi codes sent back by the
device.
