Make sure you get *good* dvd blanks. The really, really cheap ones have a
really, really cheap glue which starts to disintegrate after a while, rendering
your DVD backup useless.
Google is your friend.

Eric,
My 150MB tape is from 1994.
Knock on wood, I still have a lot of 2 gig dat tapes from 1996
that I have successfully restore from, perhaps it is time to restore them all
and backup them up on DVD. Although I have heard some brand DVD RW are not that
reliable. It sure beats tape backup. And recently the prices of the DVD -R and
+R are amazing cheap.

Sounds bad. If it's any consolation, the tape probably wasn't any good
before it got grease on it; I recently went back to pull some data off
of several SGI tar'd DATs from 1995-1997 and they were all corrupt.
They've been stored in a cool dry location and were tested before they
were put into storage four years ago. Methinks the format isn't as
solid as the tape manufacturers would lead us to believe.
I'm hoping that my DVDROM backups withstand the test of time.

Anthony,
Thanks for your input.
I have given up.
I do have a an old Indigo hanging around and I was
able to put the system back together and running.
Unfortunately I forgot my 150 tape drive was defective, it was giving
me I/O errors
I tried a few times and when I pull the tape out it had grease on it.
I
think
it is history. Oh well, it would have been nice to get those models
back.

DAT was the most common drive used on SGIs. I have some experience
trying to use SCSI DAT drives on Windows and its not fun.
Plus, the Irix tar implementation did reverse byte ordering and had
bigger block sizes and stuff like that, so you really need a command
line tar tool (and dd) to make it work.
here's the easiest;
1) Find someone with an SGI hanging around you can borrow.
There are a LOT of them in closets.
2) Use a linux machine
3) Use a Max with OSX, it has a full command line tar implementation
4) Pay someone 50$ to do it, who has the SGI running and a DAT drive,
etc.

Is there a magic utility? or is it wishful thinking?
