這個方法是某為位大大post，剛好我有備份起來，
好像win2k的sp4有支援127G以上，

win2k support 127G以上的HDD
1. Run "Regedit.exe"

2. Finding the key in the registry "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Service\Atapi\Parameters"

3. Add a "DWORD value" by select "Edit" function in tool bar of Registry Editor window, then add the value as following:

Value name: EnableBigLba

Value Type: REG_DOWORD

Value data: 0x 1

4. Close registry editor window and restart.
改為 1即可
