I got this today in the mail, and ripped out my laptop drive to try it out. Pretty easy, the end of the case is really just a "cap" that comes out and has a connector that the drive plugs into. The rest of a case is like a sleave for the drive. Above poster is correct, kinda cheap as nothing holds the drive other than the connector. But it works. no drivers needed just plugged it into my desktop and transfered about 4.5 gb in about 5 minutes from my 3 yr old 30gb 2.5 drive (I suspect its 4200rpm).
