I recently replaced the CD/DVD optical drive in my Inspiron i14-3437-a40 with a new 240GB Kingston UV400 ssd drive in a caddy, but it's not being recognized at all by the computer. It does not appear neither in the BIOS nor in Device Manager/Disk Manager tools in Windows. The CD/DVD drive worked fine though, so I doubt it's an issue with the connector. I have updated the SATA drivers and the BIOS using Dell's tool in the website, but apparently it was not a driver issue. What could be the reasons for this problem?
