XP Pro convert to NTFS

I converted my XP Pro OS partition from FAT32 to NTFS. Because it was only a 3.5G partition my cluster size was already 4K.

Under these conditions, is there any noticeable advantages to a clean install on NTFS over a conversion?

TIA

If the cluster size hasn't changed then the performance shouldn't be affected either. Here's a good article on how to get around the 512byte cluster size for future reference:

Thanks SS, I was aware of the 512Byte conversion problem but decided to give it a go without prep. (I ghosted immediately before converting)

I believe I originally partitioned and formatted with PartitionMagic. (which may eliminate the odd 2K multiples problem mentioned in your link)

However I did it, my 4K clusters were maintained after the conversion.

BTW, is there a way to check cluster size from Windows? I checked it with PartitionMagic.

Maybe this will help.

Hi Dvom if you open Disk defragment and click on analyze then on view report it gives cluster size amongst other info.

Well done jenae, I've been racking my brains all evening trying to remember where I'd seen the cluster size reported :D

jenae, thanks. I probably would never have found that since I use a third party defrag.

Another way is to view the cluster size using the fsutil fsinfo ntfsinfo command. Click Start -> Run and then type "cmd" (without quotes).

At the command prompt, type:

fsutil fsinfo ntfsinfo c:

This will give you an existing report about the volume. This was provided in the link I provided above.

ecross, I guess I just glossed over that article the first time. From that article I also tried the "chkdsk" command and got the cluster size.
