LOL, actually Windows allows you to see the full size of the harddrive,
but without a 48bit LBA enabled BIOS, anything past the 137 GB mark is
not addressable meaning that data cannot be written to it. Windows will
still show the full capacity of the disk at least. I am pretty sure SP1
will do this automatically, but you can do it manually if you want
through Regedit. Find:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Atapi\Parameters\
and set EnableBigLba to 1 ;)
It is true that if you want to use the full harddrive (past the 137 GB
mark) then you need a 48bit LBA capable BIOS or a controller card. Many
harddrives larger than 137 GB come with a free controller card too :)
