After a fair amount of juggling, I have determined that all the ports are good and the cables are good. So that tells me that the drive is bad. What is the easiest way for me to use that unassigned drive (which is the same size as the bad data drive) as the new data drive? Thanks for your assistance thus far. (Interestingly, when I plugged in the bad data drive, it made the adjacent port good drive disappear in the BIOS sata configuration. Not really sure why that would be.) Also, my cache drive became unmounted. I re-mounted it, but it is not showing as cache. How do I re-establish this as cache? Thanks

Correct - unassigned, not unmounted. I'm using an old hulk of a tower pc as a basis. The missing drive is stuck in a drive bay, connected via sata cable. The cache drive is an SSD, also connected via sata. Taking another look at BIOS sata configuration, the parity drive and unassigned drive show as connected to sata plugs. All other sata plugs show as empty.

I cannot see this drive, nor can I see the SSD cache drive. I can see my parity drive and another drive that is unmounted.

Here are new diagnostics after changing controller setting tower-diagnostics-20250119-1421.zip

Thanks. Prior to changing this, should I make this change for all discs in the system, including parity disc? Or just the affected disc. Thanks for the help. Also, I just realized that it says there is no cache installed. I have an SSD installed as cache that was being recognized before. I was going to ask if that also need to be changed to AHCI but I don't see it at all now.

I saw this basic subject line in another post. They posted smart test results and diagnostics. I have the diagnostics (below), but when I try to run a smart test (short) the button just toggles stop/start and does not perform a test. Does that mean I have a dead drive? Thanks for any help. Also, here's a screenshot of warnings. tower-diagnostics-20250118-1238.zip

Guys, thanks for your help. As this is a relatively new server with not much on it, I'm going to just delete the contents of the flash drive and start over with a fresh install. Thanks again.
