Has anyone broken the 2.2tb limit

Post by reliantkcar »

My original xbox with the 2tb is overloaded and I was wondering if anyone has enabled LBA 48 on a xbox yet. If not what is required to do so?

The xbox kernel sector count can't count high enough to extend the size of the hdd.

part of the problem is the processor is only 32 bit so it can't process a 64 bit sector number directly in hardware so it requires processing the number half at a time for each sector read/ write which may reduce the speed of the xbox when acessing beyond 2.2tb.

It would require assembly patching the sector count in bios, formatting the hdd in larger clusters may work but the file system becomes real wastefull, there is no tools around able to format the required cluster sizes also.

2^32 x 512= 4 294 967 296 x 512 = 2 199 023 255 552 (= 2.2TB)

what about replacing the dvd drive with a harddrive and running dual drives?

the xtender kit allowed you to select between one of three drives when booting the xbox:
The bios in the xbox is coded to see a dvd drive and a hdd and cant be changed.
