Yeah, I think it's probably about right, but i'm a little suspicious  
the possible partition table doesn't mention an extended partition.   
I'm trying to find a similar disk so i can backup the whole 30gig  
drive.... BEFORE "fixing" anything.
is parted the same as Gparted?  It seems to have a bunch of more cool  
stuff on command line that GUI app on Ubuntu 5.10 LiveCD doesn't.

I suppose I could use something like
dd if=/dev/hdb of=/mnt/usbdisk/30gig-filesystem-in-a-file.img bs=512  
conv=noerror,sync

To write the whole 30 gig disk to a file on a usb drive?  how about a  
hfs usb drive? (my linux backup partition on the usb drive is only 20  
gig)

Can the file system support 30 gig files? or does anyone have a 30  
gig drive I could borrow or buy.
