Madshrimps Forum Madness - Can't format partition

I'm going to re-install XP, so I need to put my data on another partition. THe problem is, I can't format the partition.

There's a whole story, so I'll try to keep it short.
At first, my hdd was partitioned like this:

Code:

2Gb FAT32

78Gb NTFS

14Gb EXT2

Extended partition

14Gb EXT2

2GB swap

The bootmanager was LILO, but since I was about to remove the linux partitions, I did a fixmbr so I got the NTLDR back.

Then I started to remove every linux partition until I got this:

Code:

2Gb FAT32

78Gb NTFS

30Gb Free Space

When I make a normal partition and I want to format it, I get 2 sorts of errors:

Quote:

the formatting did not complete
The formatting did not complete because the medium is write protected

And when I check the properties of the partition, windows says it's EXT2 (it doesn't matter how many times I remove the partition).

BUT, when I make an extended partition and a logic partition in it, I can format it with no problem, but that's not what I'm looking for.

How can I solve this ???
