Hdd deteched on BIOS but weird on windows Tags: New Build Hard Drives Systems Last response: September 24, 2010 6:00 PM in Systems Share onlysony September 20, 2010 11:39:25 PM hi guys, i dunno where is right section for this kind of questions... so i just decided to ask here. i just built my computer for the first time, and it seemed slower than it should be. so i was checking stuff and when i was looking at total space from :my computer: it says 127gb. although it should be 800 gb. so i checked on BIOS for hdd drive, it detects HDD on SATA 1 for 800 gb. so i checked on windows again, it still says my C: total size is 127 gb and didnt recognize any other drives. i installed windows XP and i didnt seprate partition. and when it asked for format before install, i said to do fast format. is that possibly why? Please help.
