Windows doesn't provide any tools for converting an NTFS volume to FAT or FAT32. You will have to copy the files on the volume to another location and then format the drive. Note that FAT32 is a much more limited file system than NTFS, and there is probably no advantage to doing so on a server.
Windows 2000 and XP computers utility for formatting only supports 32GB formatting for fat32. However, FAT32 allows up to 2TB of space to be formatted from ntfs. So most likely your using XP. Search Google for "Disk Format Utilities" and you can find ones that will format your drive from ntfs to fat32 without losing space.
format /fs:FAT32
FAT - FAT32 - File Allocation Table
The only way i know is to format it to FAT32. Remeber to make a back up.
If it's not formatted FAT32 already, you will have to format it to FAT32 which erases the data on the drive.
copy it to your computer hard-drive re-format and just copy the files back over!
FAT or FAT32.
Windows basically uses two file systems:-1. FAT2. NTFSFAT stands for File Allocation Table. FAT was first introduced in 1980 as FAT12, followed by FAT16 in 1984 and finally FAT32 in 1996. The numbers 12, 16 and 32 represent the bit size of a FAT system.Nowadays, in Windows we get to see two FAT options which are FAT and FAT32. Simply FAT means FAT16. FAT16 partition size is limited at 2 GB for sector size of 512 bytes.FAT32 volume size is 2 TB for a sector size of 512 bytes and 16 TB for a sector size of 4,096 bytes. The maximum possible size for a file on a FAT32 volume is 4 GB minus 1 byte or 4,294,967,295 (232−1) bytes.NTFS stands for New Technology File System and supersedes FAT system. NTFS was introduced in 1993. It allows a maximum volume size of 256TB and 16TB file for sector size of 64KB. It has numerous advantages over FAT systems.Microsoft is coming up with a new file system with the release of Windows 8.
