Xbox360 USB Storage

Anyone who bought an Xbox 360 with the original "20gb" release of harddrives knows that they're restrictively low on capacity. This is made worse by the Xbox's system caching procedures (etc), so ultimately you're left with about 14gb of user space on the drive. If you play more than a dozen games, each of which have updates downloaded from Xbox Live, your drive fills up very quickly.

I'd been getting nervous about it, thinking I'd have to go drop some exorbitant amount of money on an over-priced, Microsoft-branded harddrive, when they decided to enable storage of Xbox data on USB drives. Since I've got a couple spares lying around, I opted to try it out. Here's what I've learned...
  • The Xbox 360 supports only one partition per USB drive, and it should be FAT32.
  • Extra partitions can still exist on the drive, for use on other computers, but only the first is used/recognized by the Xbox.
  • If you provide an un-partitioned drive, the Xbox 360 will create a filesystem filling the entire drive - which breaks on some systems. I recommend pre-partitioning it.
  • When the Xbox 360 "configures" the drive, it creates a directory and occupies/reserves 16gb (or however much you select) for itself - in chunks, since FAT32 doesn't support more than 2gb per file very well.
  • The remainder of the space on that partition is available for you to store music, videos, etc - but you'll have to do that from your PC.
While I think Microsoft is (per usual) playing the tyrant with it's 16gb limit, this feature is at least a marginal improvement. It's significant enough for me that I appreciate it.

The technical (filesystem) requirements are specific, but not terribly unreasonable, since the practical benefit of using such a harddrive with an Xbox 360 pretty much ties the drive to the Xbox. Most users shouldn't be too hassled with it.

Improvements I wish Microsoft would make:
  • Remove the hokey 16gb limit - it's not a technical limitation, it's a marketing decision.
  • Allow games to be installed on the drive completely, not requiring the disc to be present. I don't mind tying the installation to my hardware and the disc (jointly), but I want the convenience of playing without inserting the disc at all!
That's it for now. I'll be playing with my new expanded Xbox 360 storage if anyone needs me...
