I bought one of those hd 3.5 enclosures. I connected all ports..to my net book..usb, ps/2 and etc. The product is suppose to be hot swapable and plug and play. After booting the pc, i did not get the usual plug and play notification...so i went to device manager and saw no yellow marks..but do not know what to look for...just to see if my product is even working...The last thought that came to mind, which i have not done at this writing, is that maybe it has something to do with the jumper on my hd. Anyone else had experience with these inexpensive enclosures? many people swear by them. Absolutely no instructions came with it.
