im not sure if this is the right place to ask this but here goes.
i just got a custom PC and i got two 500gb hard drives i backed one up on the other one, now i cannot acces the back up drive. it doesnt show up on controll panel device list either.
when i turn my PC on a black screen comes up and it says
Hard drive error 4
press F1 to start
(it says something like that)
does anyone know whats might have happend? im clueless, any help atall would be very helpfull.
