Formatting a Large HDD to FAT32

When I used to format HDDs or USB drives I never really thought about the different options available, like NTFS, FAT or FAT32. As long as it worked, right? And they all did.

Though there have been times when a USB drive wasn't recognized for no discernible reason, I attributed these instances to cheap USB drives. It wasn't until recently when my PS3 wouldn't recognize a USB drive that I gained enough motivation to investigate.

Turns out the PS3 will only recognize FAT32-formatted disks. It also turns out that FAT32 is format that's pretty much universally recognized by various O/S.

Unfortunately, while Windows Vista will recognize HDDs of any size formatted as FAT32, Vista itself will not -- by design -- format anything larger than 32GB as FAT32. Eh?

I think that deserves another, emphatic eh?! Especially as HDDs these days are much, much, much larger than 32GB, and I don't really want to partition a 1-2TB HDD 30-60 times.

FAT32 does have limitations, however, which is at least in part why Microsoft prefers formatting HDDs via NTFS. FAT32 is only useful for up to 2TB, I gather, and individual files can't be larger than 4GB.

I hope there are other technical issues that contributed to Microsoft's decision to not allow formatting anything larger than 32GB in FAT32, though frankly I can't be bothered to find out if there are.

All I wanted to do was format a 500GB external HDD via FAT32.

The first potential solution I found was appealing and simple. In Vista, open the DOS/command window as an adminstrator, format /FS:FAT32 x: Although this appeared to work at first ultimately an error message came up stating the drive was too big.

The second and successful solution I discovered was utilizing a little FAT32 format routine (free!) from Ridgecrop Consultants Ltd.. A simple matter of putting the exe file on my computer and running it (fat32format x:) from the command/DOS window allowed me to format my 500GB as FAT32 in a single partition.

Anywhoo, apparently I can now hook up my FAT32-formatted external 500GB HDD to my PS3 via USB for increased storage space, or do a complete backup of my PS3 should I so desire.

Oh yeah, I'm sure everyone is already aware of this but, in the interest of preventing a nasty surprise, I feel compelled to unnecessarily remind anyone reading this post that formatting a disk will wipe the HDD clean of any data or files. Backup as appropriate.
