Converting WD external from FAT32 to NTFS?

I am thinking about converting my Western Digital MyBook from FAT32 to NTFS. A couple questions-

1. Is there any reason not to do this?
2. Is everything I need for this included in Windows Vista?
3. Is there anything I should know besides just the normal "how to" articles on reputable web sites?

The WD external is mainly used to just backup my Outlook, videos, pictures and documents.

Thanks

acr1965,

I don't know if Vista convert.exe produces 512 byte clusters. Any idea?

Edit.... If it was my HD, I'd move the data off, delete the partition and create a NTFS partition.

 

I recently purchased a Western Digital external drive to replace a Seagate, and use it to image my notebook with IFW/IFD. The first time I created an image with the WD, it took over 3 hours, when it normally took 35 minutes with the Seagate. After reformatting from FAT32 to NTFS, the WD now takes about 35 minutes also. Go to support.wdc.com, and search for Knowledge Base Answer ID 207 for good instructions on reformatting your drive in Vista. It only took a few minutes to reformat my 500 GD drive.
