Converting XP SP2 partition to NTFS

I have a new laptop which has been preinstalled with XP Home SP2. The 80GBHDD has been partitioned 40/40 using FAT32.
I'd like at least one NTFS partition as I think I need NTFS in order support 4GB ISO downloads. I've only realised this after having installled a lot of software and got the thing otherwise configured to my satisfaction. (Ooops.)
XP is installed on the partition nominated as C:
The partition nominated as D: contains the restore point information.
If I convert D: am I going to lose my restore points?
Are there any other things I need to watch out for?

Converting XP SP2 partition to NTFS

The main thing to watch out for appears to be if your disk was originally formatted with earlier versions of Windows.

"With FAT formatted drives created with earlier versions of Windows there may be 2KB system sectors before the data starts and as the cluster size is often larger than 4Kb, you may end up with 512byte clusters which isn't an incredibly efficient conversion."

May be of interest:

As far as I can recall the only drive I've ever done this to is a removable disk (to get a greater maximum file size for backups). I don't think you should lose your restore points, I don't see any reason why this should happen (Edit - unless of course everything goes seriously titsup!).

If you convert the repair partition, the 'boot into repair' sequence will no longer work, and you will lose your i386 folder and other crucial files required to repair a broken installation of windows.
You can quite easily and safely convert your system partition using this command though

from command prompt:

convert C: /fs:ntfs

Converting XP SP2 partition to NTFS

@ndpugh This was "out of the box" so I don't expect it has been upgraded from a previous version & thanks for the links. I'm a bit unconvinced by the one that mentions "realigning" as it rather implies that every conversion will end up with a 512byte cluster size.

@micromecca By "repair partition" i assume you mean the "hidden" 4GB partition (can't recall the partition name as i'm replying from work) that you can't directly address --I certainly wasn't going to touch it.
i386 directory appears on be on the C: drive.
It's an acer 5612wlmi by the by.

thanks to both of you. I'll probably give it a try this weekend but will be burnign a few backups first ... it wouldn't be the end of the world if it all went PT but it would be a PITA
