Now, we hear a whole gaggle of complaints about how there's no defrag util for the XBox because of the propriety (and undocumented) XDFS filesystem. It's also a bitch when you can't read a XBox-formatted HD on your comp if you swap it out (without formatting the drive and losing the data, of course).
Now, what if I BIOS was written that supported NTFS (FAT and FAT32 would be pointless because neither supports very large drives or files located on said drives), so a defrag util could be easily ported. It would also help if you wanted to copy the contents of the entire drive to another one by simply swapping both HDDs into a comp (kinda like that neat feature that's supposed to be in the NeXGen dash, only MUCH faster than Ethernet).
I know, this feature would be much harder to implement than, say, the Signed XBE check or the No Eject on Reset hack, but it'd be damn useful. Perhaps that hooked C/C++ code that the X-Ecuter team was bragging about would make such a feature possible?
