Enclosure doesnt work :(

I have a pioneer drive, with http://www.ebuyer.com/product/143273/add_product_review?accept

I’ve tried installing the drive with master settings, the led on the back shows green, but no hardware is detected on my computer (using device manager), same thing when I set it to cable select, but the led goes red when I set it to slave.

Am I doing something wrong?

You cluld try to plug the Pioneer drive directly via IDE / SATA to your PC to check if your drive works or not.
In case your drive works with no problems, I’d guess the bridgeboard chipset of your enclosure is not compatible with your Pioneer drive or is damaged.
