Hello. So I bought Lenovo B50-80 + SSD. I replaced WD disk with SSD and put WD to HDD Caddy. It is not working though. It showed as "unknown device" and it took about 2 minutes more for computer to boot up with caddy connected. (I connected it instead of DVD rom). So I removed it and put into my old Asus N55SF, and it is working fine there. So I did a format, named the HDD and put it back to Lenovo. It was still under "other devices", but now with name: WDC WD10JPCX-24UE4T0. Still not working. It won't show in BIOS nor Windows install, but why is it working fine in Asus? They both have same systems, Win 8.1 64bit, only difference is that Lenovo is UEFI with SSD formatted to GPT, Asus is standard BIOS boot and MBR partitions. I tried some solutions, like uninstall Intel Rapid storage, but it was never installed, since I have my own Windows installation. What could be the problem?
