Yep, you are right in that it is the directory version not the filesystem
version. We are rapidly coming to the same conclusion about figuring a way to
connect to an SGI box to get the info off. The drives are from the Onyx
Stampede drive system that uses the high voltage SCSI, so it's kind of tough to
interface to. We'll have to figure out if it is worth it. I think we might have
some tapes around that may have the info. The tape part we already have figured
out, it's just the drives would have been faster.
Oh well, where's my hammer.......
Thanks for the info, If I figure something out, I'll pass it along,

You'd be talking about the directory version, then, not the version of the
filesystem? Irix 6.2 introduced Version 4 filesystems, but version 2
directories didn't come along until a couple of years later. See Slides 6-7
As it is, the dirv1 removal commit says "Never functioned on Linux, just pure
So I suspect that the only way you are going to be able to read those
filesystems is with an Irix machine....

Yeah, that's old ;)

Nekochan is the place to go for information about old SGI boxes.
It might be worth posting there to see if there is anyone local to you with
working hardware that would enable you to pull the information off the disks....
