It diff a tad on the fact that i can get.. the computer doesnt come with 
raid except one but the same problem on all my ubuntu installs... its 
something that has changed on the 2.6.13+ kernels that has that effect a 
friend tells me.. it happends on drives that have just one partition or 
some crazy thing like that.

heres the mount output on me box:

/dev/hda2 on / type ext3 (rw,errors=remount-ro)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
usbfs on /proc/bus/usb type usbfs (rw)
/dev/hda1 on /boot type ext3 (rw)
/dev/hdd1 on /media/multimedia type ext3 (rw,nosuid,noatime,user_xattr)
/dev/hdc1 on /media/storage type ext3 (rw,nosuid,noatime,user_xattr)
tmpfs on /dev type tmpfs (rw,size=10M,mode=0755)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)

dev HDC is the one with the problem.. it mounts fine in kernel 2.6.12 
but not in any other over that. it has just one partition.

dev HDD is the drive that DOES mount in all kernels i have tested.. it 
has 2 partitions: 1 the data 2 a swap ( 400 mgs ish )

im really not sure what the problem might be, i dont think the partition 
table and or format the file system has might be whats keeping it from 

both HDC1 and HDD1 have similar ext3 configs... the only diff is that 
HDC1 is set to LARGEFILES and HDD1 is set to LARGEFILES4 or something 
like that.
