I really hope someone else has come across this kind of issue.
We have a Dell M6500 made back in 2011. It has a 500G sata drive in it now and it is messing up. I have been trying to replace the drive with a 240G SSD for weeks now but when I take the old drive out and put the new one in, the computer does not see the drive at all. Since it has 2 drive bays in it I put them both in and still does not see the SSD.
I know its not the SSD because I put it in a desktop PC and shows up just fine in the BIOS. When I have just the SSD in the M6500 I cant even get to the BIOS. I have found other forums about this issue but they all talk about the mSata which I am not using.
When the old HDD is in the PC I can get to the BIOS fine and in the BIOS I have changed the Sata Operation to all options and still no luck with the SSD in there. Anyone have any ideas?
