I use win2000. A large FAT32 drive with a 512bytes cluster is very slow... Once a time I converted a NTFS drive (about 44GB) to a FAT32 using Partition Magic 8.0 ...Oh! the cluster remains 512bytes! Then I use chkdsk to check for errors...no errors...but windows automatically expand my virtual memory size... Accessing the drive is really very slow. NTFS has advantages
