Didn't try it out right away, but did in time to return it. it only worked on 1 of two 3.5" IDE drives I had, 1 of two 3.5" SATA, 3 of four 2.5" IDE, and none of three 2.5" SATA drives. Also, near the end of test, it was making the laptop drives seek/click, which had me very worried till I could find another adapter.Definite pass, even if it were half of this price and I was desperate.
