You'll find it best to back all the data up onto something, remake the partition, then re-install the data. As mentioned earlier, convert.exe is 1) a one-way trip, and 2) inefficient as Hell. (mind you, most of my partitions are in ext2, but since Windows hasn't a clue as to what those are...) The one and only advantage you're gonna get out of NTFS is the ability to set permissions on the files and folders on the partition. This is a real good idea if your poser directory is loaded with stuff like "Ulf's Penis Prop", and you don't want your kids to fire up Poser (or at least your copy of it) inadvertantly. (Incidentally, you can keep more than one copy of Poser, even on the same hard drive, and each in turn will run just fine. Handy if you do have kids and want them playing with Poser, just not, say, the Vicky genital props and the leather corset kit.) Otherwise, NTFS isn't much of an advantage. FAT32 runs gobs faster, and has far less overhead (expect to lose around 2GB for every 20GB of space to just use NTFS.) FAT32 is readable by OSX or Linux no sweat, and an NTFS partition is unreadable by Win98, ME, and earlier. HTH a little, /P
