I have one of those USB hard drive cases, and I have my old hard drive
in it.
Eventhough I have made the changes to mount multiple USB drives in one
USB device (works fine for my media play with internal and SD drive), I
am only getting the first partition (/Boot (2)) automounted.
df does not show anything more about the drive, but the gnome hardware
browser shows all three partitions on the drive:
/dev/sda
sda1 ext3
sda2 linux-swap
sda3 LVM Physical Volume
Naturally it is sda3 that I want to access.
So far my google searches have come up empty.
