Hi friends

I would like to share this with all. This info can be helpful to
someone

Win2k-SP3 and WinXP-SP1 supports 48 Bit LBA (Logical Block Addressing),
though one have to enable it manually to get access to the HDD space
beyond
137 GByte (Ofcourse the IDE BIOS has to be able to support 48 Bit LBA
too).

This is done with the following DWORD registry key :
[HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Services \atapi
\Parameters]
EnableBigLba = 1
Though be careful when switching between OS's which doesn't support 48
Bit
LBA, as they can cause data corruption.

So are you supposed to change the key's value, add the key, or what?
