quick question, and i'm sure i deserve a quick answer! some might say i should have looked around a bit more and maybe i would have found the answer.. but i'm a bit fragile today, and remember, 'there's no such thing as stupid questions; just stupid people.' here goes; with regards to putting a large hard drive in my laptop which is the most important factor to recognising the drive, bios or service pack? (or both). i have xp pro sp2 (also access to sp3) and i bought a 120gb drive to be safe (and it works fine), but i just wonder if it would recognise a bigger drive than that.
