Hi - I've been asked to re-partition a
Dell 120 GB 5400 RPM Encrypted Serial ATA Hard Drive
and install CentOS 5 on the new partition.
It's a Dell Lattitude E5400 laptop.
Is this even possible with encrypted drives?
How is it encrypted? Some new laptops come with drive encryption
built into the hardware which I believe is totally transparent
to the OS, sample device:

Looking at this:

The drive they have seems similar, so I would expect
re-partitioning to work fine, though of course backup any
important data before trying.

Excuse a really dumb question, how does this provide me with security?
I assume it still uses the normal SATA interface and thus the OS writes
to the drive as normal, but now it is encrypted onto the physical
media..... so now I steal the laptop, or just the physical drive, plug
it into my SATA controller and voila read all the encrypted data off the
drive???
I am obviously missing something - there must be a key somewhere off the
drive for this to work as a securely encrypted system.
Flumoxed!
