I will try to clarify. When the disk was on my pegasos2 machine, the
disk was connected through the pata channel and it was "hda".
Now I took away the disk from the pegasos2 machine, I put it in an
external pata2usb box, and connected the external box to the x86
machine via usb.
It's not a USB disk by itself but, yes, it has been partitioned and
the filesystems on those partitions have been created on my pegasos2
machine.

I used it in the subject line to make it shorter. And between double
quotes. What I meant was of course "a disk with a non DOS partition
table". Furthermore I didn't address the disk with '"ppc" disk' in the
rest of my message.

The partition type matters as well (DOS, MAC, AMIGA, etc.).

That alone wouldn't explain why the system doesn't create the "sda1",
"sda2", "sda3", etc. block files under /dev.
For instance: let's say you have a disk ("sda") with a MSDOS partition
type and several filesystems on it. One of the filesystems is a HFS+ one
and it's on "sda10".
1) Even if you didn't have the HFS+ support enabled in your kernel the
system would still create the "sda10" block file under /dev. You
wouldn't be able to mount it.
2) And if you had the HFS+ support enabled in your kernel but you
didn't have the HFS+ specific packages installed on your system then
you wouldn't be able to create or alter HFS+ filesystems but the
system would still create the "sda10" block file under /dev.

On the disk I used on my pegasos2 machine there was at least one ext3
filesystem.

Well, I apologize. Myaybe this is not the right ML to ask to. I just
thought that, as ppc users, some of you might have experienced the same
issue as well.
