And, as I have just replied to another thread....
In case of Windows 2000 SP3, the following Q305098 applies:
http://support.microsoft.com/default.aspx?scid=kb;en-us;305098
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.
Microsoft has confirmed that this is a problem in the Microsoft products
that are listed at the beginning of this article. This problem was first
corrected in Windows 2000 Service Pack 3.Important Although support for
48-bit LBA is included in Windows 2000 Service Pack 3 (SP3) and later, it is
still necessary to create the registry change that is described in the
"Resolution" section of this article.
