New SATA drive with partition trouble

[TroyAB77]

Hello,

I've just built myself a new computer, and put into it a SATA HD that has a
250GB capacity. My BIOS seems to be up to date since it regonized the full
250 gigs.

However, I had to install an old XP home OS on it and it would not recognize
more than 137GB's. After installing vista I can now see a unallocated
104GB's but it will not let me reformat my drive any larger than the 137GB's
it origanally detected.

I've tried to do some research on the 48-bit LBA feature, but it all
pertains to XP SP2. And there is virtually nothing that talks about it for
vista.

My question is this, how do i turn this feature on? I've found that I have
version 5.1.2600.0 of the atapi.sys and for xp it recommends getting SP2
which will update it to 5.1.2600.1135. I don't know if that has anything to
do with anything, but just thought it might be helpful to put it out there.

Thanks,

However, I had to install an old XP home OS on it and it would not recognize

Then it was pre-SP1 XP.

After installing vista I can now see a unallocated

Reinstall Vista cleanly by booting from the Vista DVD, and start out
by deleting the existing partition and creating a new one of 250GB (or
whatever size you want).
