Why is EvoX only support hard drives up to 120 gigs? (Actually isn't it technically 137gigs or something?)

Will there be a future patch that'll allow for a larger hard drive?

Question is just out of curiosity really. Thanks anyways. beerchug.gif

The normal ATA standard uses 28-bit addressing for sectors on a drive. When all 28-bits are set you get the number 268,435,456 or the maximum number of sectors on such a drive. Each sector is 512 bytes, so that's your 137 GB.

That's why drives bigger than 137 GB support a new 48-bit addressing scheme so that they can be many times larger. But aside from the drive you also need support for this in the BIOS and the OS. Right now this does not exist as far as the XBox is concerned and I don't know if it is even possible.

I figured there had to be something more then just a software issue. Nice explaination, btw.
