Regarding the first part: I'm using GMail. I clicked "Reply" at the
bottom of the most recent message. I'm not sure if that should fix the
problem. Just let me know and I'll change.
Anyway, I've tried plugging the hard drive into a windows xp computer,
and also into a vista VM in VirtualBox. In My Computer, the hard drive
does not appear at all. Keep in mind that Ubuntu does not show any
sign of the hard drive at all either, but it does show up in GParted
in Ubuntu, and it shows up in the list of USB filters in VBox, so
Ubuntu does recognise that there is a device. It just doesn't realise
that it's a hard drive. Seems like Windows Explorer is doing the same.
However, when I plugged the hard drive into the XP computer and opened
up compmgmt.msc, the hard drive was there. When I right-clicked on the
partition, all of the options were grayed out, except for "format",
which would make me lose all of my data. I'm not sure that windows can
really help me.
I also tried compmgmt in the vista VM, and the same thing happened.
