I recently put together a SFF with the sole HDD being a WD 250GB SATA. However I can only use 133GB of it, although I have installed SP2, been into hard drive management and can see the other half... but when I ask to extend (in DOS window) I get an error message. I've also tried extending with partition magic, but that hasn't worked either. Someone mentioned bigLBA, but I haven't been able to find a download for it.
Any advice would be most appreciated.
