Thanks, I will try that.

All the partitions mount without problems, but I'm trying to figure out 
how not to have to do it manually every time. The device names and mount 
points and fs columns in fstab I don't have a problem with. It's that 
4th column (flags?) that confuses the hell out of me. For example, I 
have no idea what the "defaults" are. Elsewhere, I've seen it suggested 
that it should read "noauto,users,rw,umask=0", so that's what's in there 
now (and not working). I remember reading something about those entries 
a long time ago that didn't make much sense to me, so I'm trying to find 
documentation that will.

Or maybe it's the 5th column that's screwed up, since I have 0 0 where 
you have 1 2? I can't seem to recall fully what those numbers mean 
either. Something about whether or not the fs gets checked at boot time, 
if memory serves. But, once again, docs seem to be lacking here. Perhaps 
I need to learn this well enough to write a new fstab doc, but I need 
others to help me learn it. ;-)

Thanks again,
S.

p.s. does the "s" in "sdx" mean scsi drive? All this time I thought it 
meant serial drive.
