Hi!
My problem is similar to above, when cleaning (AVG Pro) a friend of mine's hardrive on my PC that was riddled with viruses,namely... ("Windows XP Anti Virus Pro, this virus conned my friend in downloading this") All was done and I re-installed his hard drive in his PC and just needed windows repair and was sorted.
BUT! Now my third hard drive which I unplugged, which shares the same connection as my CD-ROM,they both do not show on my bios screen,but have power.
I have two other hard drives connected on a other IDE connetion (one Master and Slave) they are fine!Re-booted several times...no joy.I have even swopped the two IDE connectors around...no joy.Has this virus done something?
