XPS L502x: 2nd Hard Drive using a Universal Caddy in Optical Drive Bay

Hi,

I am trying to replace my optical drive with a HDD Caddy with a Seagate 2TB HDD. When I start my laptop with the drive installed both my bios and os don't recognized it. If I start my laptop and then slide the caddy into the optical bay my os picks it up immediately. If I restart the computer the drive is gone. I have discussed with the caddy manufacturer and they aren't sure what the issue is. I have updated all my drivers and my bios via Dell's website.

Can anyone provide some insight?

Thank you.
