Filesystems, Disks and Memory

I started on another thread and full story can be seen here: https://www.unix.com/security/91428-h...-system-v.html

But my situation turned to land on this thread now.

I have old scsi HDD out of the UHC UNIX System V Rel. 4.0 Version 3.6 box. And need to read it somehow on another box. Installed Ubuntu linux, but cant mount it. There is what i have (i need to read Maxtor scasi disk):

Anybody knows what can be wrong here? Or how to read it?

You should mount /dev/sda4 since, according to your post, this is what fdisk -l sees as a valid partition. Mounting /dev/sda mounts the device as if there were no partition table there at all!
