Got win2k running, and putting a new HD in your system but the size does not seem match what you had in mind??… Well check if you have win2k enabled to handle disks > 137Gb.
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.
5. Reboot and check again.. 🙂
