My experience is that if you can find an Exabyte EXB-8500, you can
probably read that 8mm, newer drives may also work just fine (it's been
enough years, I forget just how new of drives we've been able to read
8mm tapes of that vintage on.
What's likely to be difficult though is the 4mm tape. The 4mm DDS tapes
are probably proprietary to the drive model, and potentially to the
drive they were written in (if the heads were out of alignment). I hate
trying to recover 4mm data. Was it written using a SGI branded drive?
If so that would make things easier. Actually if it was written a drive
that was relatively new in 1998 it might be easier, buy then things were
fairly standardized.
No clue on the Linux/IRIX question, but I would imagine Google can help
you there, as that seems like a common enough problem.

I used many years
ago, the last effort was trying to recover the data from a hard disk
that ran a WFW 3.11 system. The problem was the disk could not be
read on a modern computer, so I recreated an old system and (very
lucky for me) ftp'd the data off the system after I found an ISA
network card.
I have a couple of 4mm and 8mm tapes that contain data I want to
recover. The 4mm is DDS-1 and was written using tar on a SGI system
in 1998. My questions are;
'What modern DAT tape drive will read this tape? How backward
compatible is this technology?'
This seems like an easy problem and intend to use a linux system to
read the tape.
The 8mm tapes were also written on an SGI system, however it was in
1994 and the IRIX Backup utility was used. IRIX 5 was probably used.
Any ideas?
