Re: Should I enable "48-bit LBA" in this case?

Ken. If yiur O/S is WinXP Home or Pro, with sp1 or sp2, You're Bios

Well first, I didn't say anything about what was required for 48-bit LBA. I
just pointed out that if he was already seeing the full size of the drive,
all was well, and there was nothing more that needed to be done.

But nevertheless, what you say above is *not* correct. You need *two* things
to support a drive that large--just SP1 or SP2 is not sufficient:

1. A motherboard with a BIOS and controller that supports 48-bit LBA (or
alternatively, an add-in controller card that does).

2. At least SP1 of Windows XP.

Hello, hope any of you guys can help me with this because I can't
figure it out on my own.

My Hard Drive has a total capacity of 189.91GB or 200GB but I've
divided it into two partitions:
The Primary partition is the smallest and has 76GB.
The Secondary partition is the biggest and has 113GB.

This Hard Drive is connected to the motherboard using an IDE cable
(P-ATA interface) and is set as Master.

So the question is:
Do I still need to enable "48-bit LBA" when none of my partitions
exceed the old "28-bit LBA" limitation of 128/137GB?
And If I do need to enable it, how do I enable it?


No, it's already enabled. If it weren't, you wouldn't have been able
to see more than 137GB and wouldn't have been able to create
partitions totalling more than that.

I'm using Windows XP Professional with SP2 and the latest security
patches. I've successfully flashed my BIOS so it can now support
drives larger than 128/137GB.

Please help!
