SATA ports 3 & 4 will not see any drive on my Dell optiplex 745

By Computerlrnctr@pinehurst. ·
When I install a second hard drive on the Dell Optiplex 745 in either sata port 3 or 4, it is not reconized by the computer? These ports show up in bios but are not active? How do I turn on these ports for use.

PS: bios level is 2.1 12/14/06

Thank you.

In the BIOS

You should see drives listed - 0 through 3
Each drive can be individually enabled or disabled
As I recall you double click each drive to bring up the options, not sitting in front of a 745 right now. It should say somewhere on that screen how to change the options.

Bios settings

I went into BIOs again after I looked the SATA port over on the motherboard. The SATA ports on the motherboard are listed as 0,1,4,&5. In BIOS the SATA ports are & 5. I have been trying to turn on 2 or 3 as they are the next ports and never tried 4 or 5.
When I turned on 4 and 5 everything is working fine.
Why do they list SATA ports 2 and 3 when they are not present on the motherboard?
Thanks for being patience with me.

Your Welcome

I don'tknow why the listings don't agree, maybe ask the mobo manufacturer. I did get your e-mail but I don't check that acct very often.
Glad you got it sorted out.

Just 1 question here

by OH Smeg In reply to Bios settings

Does that model Dell come with the Option to have a RAID Array?

If it does the reason is that the ports in question are set to be used as a RAID only and not for general use as extra drives.

I've seen this on several different M'Boards now and it's always when the BIOS Description doesn't match the M'Board Screen printing.
