Problems with 48-bit LBA

[Guest]

I have a 250GB Maxtor hard drive that is attached to a promise ultra 100 pci
controller, the drivers and bios are the latest offered my promise. I never
had a problem with windows "seeing" the whole drive until I recently
reformatted the drive. After reformatting windows reports the drive size as
128GB, I tried everything I could think of to get the drive to be recognized
properly, even a registry hack I found online but nothing seems to work. Why
would windows all of a sudden disable 48-bit LBA, anyone have any clue how
to re-enable it? Any help would be greatly appreciated, thanks in advance.

Reformatting means reinstalling OS? What about Service Pack?
Was your install CD slipstreamed?

Nope, sorry I wasn't clearer on this point, the Maxtor drive is a secondary
drive not my OS drive. In the end its a moot point 'cause I managed to fix
the problem by updating the driver to the newest one listed for the promise
ultra133 tx2 but thank you very much for taking the time to reply.

Thank you for letting us know.

I wonder how reformatting non-OS drive would affect promise driver
(you have indicated it worked before)?
