I bought a Sata to Usb adaptor to connect a Dvd Drive.

The Adaptor connects to my laptop but as soon as I connect the Drive to the sata port on the adaptor the Connection disconnects from the laptop. It worked the first time I used the drive and it now just disconnects. It is a 'Disk Drive' when checked under device manager.

I am running Vista 32 bit if that helps.
