i put fresh install of windows xp pro on western digital 250 update to sp1 and the sp2

windows is reading it as 137 gig ummm

so i went to microsoft for changing reg to enable large drive parameters

The following conditions are necessary for the correct functioning of 48-bit LBA ATAPI support: • A computer with a 48-bit LBA-compatible Basic Input/Output System (BIOS) installed.
• A computer with a hard disk that has a capacity of greater than 137 gigabytes (GB).
• You must enable the support in the Windows registry by adding or changing the EnableBigLba registry value to 1 in the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\atapi\Parameters
To enable 48-bit LBA large-disk support in the registry: 1. Start Registry Editor (Regedt32.exe).
2. Locate and then click the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Atapi\Parameters
3. On the Edit menu, click Add Value, and then add the following registry value:
Value name: EnableBigLba
Data type: REG_DWORD
Value data: 0x1
4. Quit Registry Editor.
and i done all the above but the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Atapi\Parameters
