Yes, ATA=PATA=IDE. The size of the drive will dictate what form of IDE. In this case, the ATA-6 have a different connector than normal IDE, which will fit in a laptop.
But I'm not trying to FIT this in a laptop, I'm trying to fit it in the Above Media Player. I really hope your right, I'm about to buy the 160GB Seagte or the western Digital, thanks for your help....... if your right...
