Thanks for all the help. I did replace disk6 and cable(s). I then ran parity without error. So far, I see no data loss.

I will do that. Disk 6 sata cable replaced. Thanks.

I am in the process of backing up files of significance. Very little is mission-critical. When I finish that I will replace Disk 6. Does that sound right?

Interesting. I did complete both short and extended self-tests without error. and yes the number of hours on the drive is over 90k (this server is now used only for archival purposes, hence its age), so I intend to replace disk 6 regardless of the SMART result. However, the parity check forced out errors (as did the original one a couple of days ago), so I am just wondering what my options are. I have to replace disk 6, but what can I now expect, given the fact of two straight parity checks with errors? Do I have any other option than to replace disk 6?

I apologize for not responding. The key problem has been fixed by a reboot, thank you. However, my initial problem is still unsolved. When I last posted, I had five working disks, but no parity, as it appeared there were errors with the drive. So, I replaced the parity drive with a new one. I just completed the initial parity check/data rebuild and it has found over 800 errors. What next? It seems that perhaps there were problems with Disk 6 and with the initial parity drive. I think next I should replace disk 6, but am uncertain if I am risking data loss. Suggestions? As ever, thank you. tower-diagnostics-20221004-0922.zip

OK, I have done this. all disks up except parity. one last thing, i hope: I am apparently now missing a key.

never mind, i got the new config to work. starting array now

Start button still grayed out. screenshot. At least disk 6 is not italicized (is selectable in the dropdown menu: see screenshot).

If I were to get disk 6 fixed (command line utilities), wouldn't this be the same scenario as replacing a failed parity drive?

It worked for a lot of years, maybe it just crapped out. How does a parity drive get repaired if it isn't showing in unRAID?

Parity still not detected. diags attached could it be a problem with the drive itself? wouldn't it at least be recognized? tower-diagnostics-20220928-1130.zip

It was SATA5, which is now, after setting to ahci, no longer being recognized (it was being recognized earlier, on the BIOS SETUP UTILITY screen like above, before changing to AHCI). Resetting SATA5 and SATA6 to IDE and rebooting now shows the parity drive (HGST on SATA5). screenshot attached.

I have attached the screen display after boot from flash drive. Per that it looks like I have all SATA devices. Also screen shot in BIOS utilty.

Changed to AHCI and saved. Diags attached tower-diagnostics-20220928-1003.zip
