Ariel,

Thank you for your suggestions.

One thing I noticed when booting up Knoppix is that
the bad hard drive takes a long time to be "detected"
during the bootup.  When the kernel is scanning for
partitions and creating /etc/fstab it just hangs there
for about 5 minutes and I can hear the drive siliently
clicking (clicks about every second).  I'm worried
that the drive may be *really* slow .... but
eventually it does boot up and I can see that Knoppix
has detected the partition.  I have a feeling that the
Volume Boot Record has been affected by the bad
sectors though...

Yes, it was just one large NTFS partition ... about
114  GB large ... about 112 GB of it personal data.

Well I did buy a 320 GB hard drive, so I could make
two identical 114 GB partitions ... but I don't need
to format these partitions as NTFS, right? ... I can
just use ddrescue to image to the unformatted space
directly, right?

Yeah ... I'm not going to use USB. I took the drive
out of its enclosure and hooked up directly to the
motherboard.
