just had a problem with my dell 1545 inspiron laptop where hard drive was bad and so replaced it with new western digital scorpion blue drive which incidentally is exact same model as previous. When i tried installing win7 it keeps blue screening. The drive is recognized in bios but do i have to set jumpers or load driver for it. Have done this couple of times before with other dell laptop models and no problem just installed drive, loaded o/s and good. Thanks.
