This thing just saved me a world of pain. Rather than try to resurrect yet another spyware infested windoze machine long enough to pull the important filez off it ... I plugged the IDE disk into this adapter, attached it to my Mac, and stuffed everything into a folder where I could burn it to a disc.
The thing handles the permutations of 2.5", 3.5" and 5.25" IDE or SATA drives, thanks to a thorough combination of power and data cables that are included.
And it was twenty-five bucks!
