Have tested the adapter Win7 already on several hard drives and CD / DVD drives (IDE, SATA). And had been working properly only on an old notebook hard drive. On the Asus 1015PN netbook it came even to total failure of all USB devices. Somehow, he responds to the adapter allergic. Since it was intended only for a hard drive gets the product even 3 stars. Otherwise, I would have sent it back. Unfortunately, there corresponded not quite the picture here. The SATA cable is hard-wired and not removable. Very inconvenient for CD / DVD drives since it is thereby the power in the way and are strongly caved need. Promote rather spend few euros more if you wish to operate the adapter with different drives.
