[mythtv-users] Hard drive failure -- recovery method suggestions

Well, the drive /dev/sdb failed the smart test.  It was one of the emails I
received on vacation.  Then it was mounted as read-only.  Then I
brilliantly rebooted the machine and it hung until I returned home.  I
wasn't getting much sleep for most of the time I was there and I did that
one morning before reading all of the emails I had received from my
server.  The vacation was really excellent otherwise!

I just put it in the external adapter and I can't seem to access the drive
at all now from a different machine /dev/sdd.

My hard drive went on a diet and is now 4.14 GB as you can see in the first
few lines below.

It may have spun for a week in that failed state.  I have never let a drive
die in that fashion before.  Usually, I'm around to cut off the power to
the system.

I am fairly certain that the drive is toast as in melba.  Should I look
into alternative medicine now or just put a pillow over its head? :)
