fdisk doesn't recognize free space on 300GB Disk
 
Sorry for cross-posting but this is probably where I should post in the first place.

System: Dell 400SC.
Disk: Seagate 300GB ATA (ST3300831A), using onboard IDE.

I just installed the new disk and allocated 100GB NTFS in Windows XP Pro,
Computer Management shows this in XP:
jiki.pbase.com/u26/taochen/upload/43368325.disks.jpg
(newbie not allowed to post URL)

Boot into Ubuntu with Live CD 5.04, I want to create a Linux partition for the rest 200GB free space, however, fdisk sees the disk is fully used:

======== screen log ========

Command (m for help): p

Disk /dev/hda: 300.0 GB, 300069052416 bytes
255 heads, 63 sectors/track, 36481 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hda1 1 36481 293033601 42 SFS

Command (m for help): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 2
No free sectors available

======== end of screen log ========

Is this a kown issue or do I miss anything?

I want to do a 'dd' backup of the other disk to the new partition.
Don't have Linux installed on this system and don't plan to.
If this is a kown issue, do you know any _live_ CD may have a working fdisk?

I burned a Knoppix CD with the lastest version, but the box doesn't recognize it's a bootable CD, guess I need to reburn with another CDR.

Thanks in advance.

293036184 = 300069052416 / 1024, according to fdisk, your first partition there is actually using the entire volume.

Device Boot Start End Blocks Id System
/dev/hda1 1 36481 293033601 42 SFS

Although its a little odd that it starts on 36k, but that's probably some oddity with huge disk boondogling, but its more or less all accounted for. I have to admit novicehood on what SFS is, but it might have a file system limitation size issue, so even though you've given it a 300Gb part it might only be reporting 100 or so.

Fdisk's size limitation is either 1.2Tb or 2Tb, can't remember which, so 300Gig is no sweat.
