I'm trying to install 9.04 with an XP partition and a Dell partition and then I'm thinking of deleting another dell partition. When I boot from the live CD, I can mount my drives fine.

fdisk -l gives this:



omitting empty partition (5)

Disk /dev/sda: 320.0 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 - 8225280 bytes
Disk identifier: 0x68000000

Device Boot Start End Blocks ID System
/dev/sda1 1 12 96358+ de Dell Utility

/dev/sda3 34671 38914 34083019 f W95 EXT'd (LBA)
Partition 3 does not end on cylinder boundary
/dev/sda4 38587 38914 2620416 dd Unknown
Partition 4 does not end on cylinder boundary
/dev/sda5 34671 34794 995967 82 Linux Swap / Solaris
/dev/sda6 34795 38586 30459508+ de Linux




When I try to use gparted or the install program on the desktop however, it tells my the drive is bare empty.

If I were to say what the heck and wipe it, I'd likely lose a lot of functionality and end up with a button on my computer that equals instant MBR death (yay MediaDirect *not*).. I'd also lose my Windows install and college starts tomorrow (I know, I'm really on top of things, eh?).

I know when I installed XP I needed to make a custom install disk with special matrix storage drivers, but I don't think that's the case here since I can actually mount the other partitions on the Live CD fine.

Does anyone know what's going on?

Take a look at the Testdisk" site. You may have a geometery problem with this disk drive. You can download the appropriate "testdisk" version and run it.

OK, I manually deleted the old Linux partition(s) with XP and now it works fine.

Out of curiosity, what on earth is a geometry problem on a drive? It's triangular and not rectangular? :P

See this for your answer.

The reason I thought this may have been a problem is from the info you posted on fdisk. You have partitions that do not end on cylinder boundary
