this was some info,found on the net about getting access too the hd through linux:
Has anyone herd of a device called MoviceBeam? Well its part owned by Disney
to broadcast movies over the unused bandwidth of PSB (or digital TV)
stations.
I recently got one of these nice boxes and started to look at what is
inside... Well its a Western Digital 160gb HDD, which is LOCKED to prevent
access to the data/drive from your home PC.
With a little encouragement (plug the POWER connector to a PC and temporarly
connect the IDE cable to the MovieBeam box, boot the moviebeam, wait about 1
minute so its accessing the drive. Unplug the power to the moviebeam
effectivly stopping all ATA communications to the drive. Connect the IDE
cable to your PC now, boot as normal to a LINUX cd... Remember once you
power up the drive you can't let it power-cycle (need to use CTRL-ALT-DEL to
reboot not RESET or power button!)... When at a LINUX prompt load FDISK...
Oh look what you find!! 3 Partitions!
1 Linux Partition (HDA1) ~ 2GB (type 82)
1 Linux Partition (HDA2) ~154GB (type 82)
1 Linux SWAP partition (HDA3) ~ 4MB (type 83)
still having problems reading the partitions due to it does not properly end
on the right boundaries and some other mess they placed in the partition...
But it look like people need to review this box to see if any violations
exist!
... They played it tough, lock the drive, embed the security chip in epoxy,
etc...
Also there is a patent on the device owned by the company MovieBeam which
goes into discussion about a journled filesystem (ext3 possibly?!?!?) and
use of sending out updated in TAR format...
Maybe people need to start looking into this one! I know I sure am!
