Partition outside disk?

Hi, I have a problem when I try booting GParted from a live cd or running it in Ubuntu I get this error: [code=xml] ====================== libparted : 1.8.9 ====================== Can't have a partition outside the disk! [/code] GParted then opens but declares my hd as 300gb of unallocated space. I believe this is because I have corrupted the partition table. fdisk from within ubuntu [code=xml] sudo fdisk -l [/code] returns this: [code=xml] Disk /dev/sda: 320.0 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x0009b837 Device Boot Start End Blocks Id System /dev/sda1 1 2432 19535008 83 Linux /dev/sda2 2433 10718 66557292 83 Linux /dev/sda3 * 10719 13315 20860396+ 7 HPFS/NTFS /dev/sda4 13316 38914 205623967+ f W95 Ext'd (LBA) /dev/sda5 13316 15865 20480000 7 HPFS/NTFS /dev/sda6 15866 28613 102398278+ 7 HPFS/NTFS /dev/sda7 28614 38403 78638143+ 7 HPFS/NTFS [/code] Briefly: sda1 is an Ubuntu installation sda2 is my /home sda3 is a windows xp installation sda5 is a Windows 7 beta installation (I was curious - I think it was the built-in partition editor that caused this problem =S) sda6 and sda7 contain media and work documents *sda8 was a 4gb logical swap partition but I deleted it as it was ending outside the 38913 cylinders. (I thought I might be able to resize sda4 after removing it then recreate the swap partition). All the OS installations boot (with GRUB) and run fine. The only thing that is concerning is that GParted wont read my hard disk. After a few hours of Googling i am pretty sure the problem is to do with my disk having 38913 cylinders and the extended partition (sda4) ending on 38914. Is there a way I can correct the boundaries of sda4 without losing any data from the logical partitions within it? Or is this even a serious issue? It would be nice to get a swap partition again in any case =P I found this post in ubuntu forums: (excuse the google cache, the forums have been down all day). [url]http://74.125.77.132/search?q=cache:MIg8KoFrVckJ:ubuntuforums.org/archive/index.php/t-352723.html+gparted+Can%27t+have+a+partition+outside+the+disk!&hl=en&ct=clnk&cd=1[/url] The above post seems to be about a similar problem. User houseam suggests deleting the extended partition with fdisk then creating a new one within the cylinder boundaries. I am unsure whether it is safe to do this however as I am not too keen on unnecessarily losing the logical partitions. If anyone can offer me some advice it would be greatly appreciated. Thanks, Tom

Doh! I see the version is from libparted, not the executable. You might still want to check to see if you need to update, if you haven't lately.

Sometimes real fast is almost as good as real time. Remember, Google is your friend!

Forgot to add, make sure you set the partition types (NTFS etc) and unless it looks like the example (in the starting and ending cylinders), just ctrl+C and start again until you get it right.
