Hello, I've got a Lenovo Y410P, SSD installed and a 2TB drive installed on my ultrabay. I purchased an ultrabay caddy from Ebay, it was pretty cheap. It worked wonders. However, just the other day I started the machine up and the drive can't be found anywhere within Windows. I've pulled the drive out of the caddy, and everything is still there and functioning. I'm concerned that either my the port inside is damaged (drive won't lock, keeps slipping in and out etc...)...I've got my fingers crossed that it's just an issue with the third party caddy that I purchased. Does anyone have experience with these third party ultrabay caddies? Are they known to die? Thanks.
