Also, DD won't work on those disks; you'll have to use sg_utils and use raw
SCSI commands to dump the disks. Linux DD uses the system calls to read
block devices, and interestingly enough, they only support multiples of
512b for sector size on that.
Dumping those disks isn't impossible, but you need the right tooling.

AS/400 OS had "single level storage" so basically a the disks were an
extension to ram, or more that RAM is just a temporary disk buffer. SO just
as a program in virtual memory can be spread across any location of
physical memory, a "file" on an AS/400 can be spread across any number of
disk sectors on any drive, which is probably why RAID is common. There is a
less worse explanation here:-

I really doubt that it can be done, and the structure of the data is
totally
dissimilar from what you can see in
windows/unix/vms.
Moreover there are high chances of being on hw raid

Not sure about mounting the drive and reading the filesystem properly
(not
much bad could happen from trying) but that gives
you the opportunity to
back it up (dd) or to potentially hex edit the raw drive itself and
overwrite the
password hash with one you do know as long as its
the exact same amount
of characters. (Any different length of characters will shift the data
that
sectors are looking for ans corrupt the drive).

The drives are scsi, are they in a standard filesystem format i could
read in a
seperate machine?

Is it
about the size of a PC tower or or two PC towers next to each other?

Alright. Picked up the machine today. Much
smaller than expected,
but everything needed seems to be included. I got a terminal as well
as a box of cables. I managed to boot the machine up to the login
screen. However
