I've a legal copy of Windows XP with Service Pack 3. I recently bought a
320Gb Maxtor PATA HDD. My BIOS recognizes 320Gb, so Linux and Plan 9
Operating Systems, but for some extrange reason, Windows XP SP3, only 128Gb.

I created EnableBigLba Key (It didn`t exist), DWORD, Value 1 in:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\atapi\Parameters

Rebooted the machine, but had no effect.

When I open Administrative tools->Equipment Management->Disk Management I
see always a 128Gb Disk instead the real, 320 Gb.

The same with Partition Magic and other partitioning tools.

My XP is in Spanish. First I installed XP, then upgraded to SP1, later
upgraded to SP2 and finally upgraded to SP3. I upgraded toSP3 because with
SP2 I had the same problem eith the HDD, and I thougt taht it would be solved
upgrading patches.

What can I do to see complete 320Gb HDD?

Thanks in advance.

Your BIOS is not set to use a partition that big. How to enable 48-bit

Is this a second hard drive in the system or have you installed windows onto
the 320Gb hard drive. If you have installed windows onto the drive then you
need to use a slipstream disk with either SP2 or (haven't tried this) SP3.
If you are installing the original Windows XP then updating with SP2 or SP3
you are still limited to 128Gb.

Not sure why Partition Magic doesn't see all the drive, perhaps the
restriction is in the bios as suggested by Mark, Unless you are running the
tools in windows.
