Thanks for this info, it's good to have 1 less problem to worry about :)

> OOI, as Eric asked, how were you able to mount it all of a sudden?

I am not sure, as I said, to narrow down the problem I am experiencing
with other disks, I decided to format an empty, healthy disk under Irix and
try to mount it under Linux. The first try was not successful but the
second was.

Right now I am making an image of the good/healthy disk using dd to
see if I can mount that
image under Linux. (It's not fun to copy 2GB disks through a
USB1.1-SCSI adapter :)
My ultimate goal is to make image of the disks that do have
partition table but refuse to mount under either OS (magic number and
SB validattion failure).
I am hoping I can edit the disk image in order to get the data back.

Again I'd like to thank Eric, you and Stephen, you guys have been very helpful.
