I have a new Dell Optiplex SFF 7070 (7th gen Core-i5). It came with a 250GB SSD only. The empty hard drive caddy inside the machine is a 3.5" SATA hard drive caddy. When I install a 500GB SATA hard drive in the caddy the Optiplex doesn't recognize it.
The documentation states that the Optiplex SFF 7050 can support 1 SATA 3.5" hard drive in addition to the installed SSD boot drive. Are there settings in the BIOS that need to be changed? For example, I noticed that the BIOS is set to "RAD on" with only 1 drive installed in the machine. That doesn't seem tg make any sense.
I have to say, Dell's documentation on this subject is sorely lacking in detail.
