MS can make some stupid decisions, but this one takes the cake.
I watch movies on my external HD connected to the 360. I was going to put some HD movies on the hard drive, but FAT32 does not accept file sizes larger than 4GB, so I converted the file system to NTFS. Well, the 360 is NOT compatible with that file system, and for some reason it is IMPOSSIBLE to convert back to FAT32. Even though MS wants to phase out FAT32, their current gen system only recognizes that file system for multimedia purposes. This is VERY frustrating. The hard drive that I bought for that exact purpose may be useless now, unless I can reformat it to something th e stupid 360 can recognize.
