March 7, 201610 yr Hello, I have 8 HDDs, Disk 5 needing replacement. They are not installed in hot swap trays I don't want to risk dismantling the whole thing. How do I know to which SATA port, and maybe even controller (motherboard or SATA daughter board) Disk 5 is connected to? I will then follow the cable. Thanks
March 7, 201610 yr There is no other way unless you have the disks labeled with their serial numbers, you are going to have to pull them out one at a time. Take a screen shot of the drives from the MAIN tab in UnRaid, it shows their serial numbers.

Take a screen shot of the drives from the MAIN tab in UnRaid, it shows their serial numbers. Print this screen shot out, and just make sure you match up the serial numbers to the same array slot once you reboot and you should be good to go. (Which drive is connected to which SATA port doesn't matter, just the assignments)

It gathers some of the details automatically to minimise the effort involved.

Thanks Maybe you can identify the drive in some way other than following the cable. Is it completely dead? Sometimes you can use the "screwdriver stethoscope" to identify spinning drives. Put the tip of the screwdriver on the drive case and the handle of the screwdriver in your ear.
March 7, 201610 yr Community Expert No it's not dead, just has some 45000 errors [emoji3] Where are you seeing these errors? Most likely a connection problem. Post Diagnostics.
March 7, 201610 yr you should check the S.M.A.R.T report to see what's up. Based on the fact that of your 450000 errors it appears there were only 13 good writes... I want to believe that there is some sort of issue with the cable.
March 7, 201610 yr Author Interesting theory. These are very old HDDs though so it is not impossible they are a bit tired. What should I check in the SMART report?
March 7, 201610 yr if you have indv leds avail for hds on your case this post - http://lime-technology.com/forum/index.php?topic=25792.msg224747#msg224747 Had a bash script that seems no longer avail so I have a copy of it here - https://dl.dropboxusercontent.com/u/17453506/identify_drive.sh Myk

March 7, 201610 yr Sorry for the Garbage pick. Its from a zoomed in and then cropped photo. I put disk number on the outside in Red and my serial number of each in yellow near the Sata connection. I bought one of those 5 Dollar Label makers. As for errors it helps none, but just an idea for future problems.
March 8, 201610 yr Community Expert SMART does not look good, I would replace it, if you want to be sure run an extended SMART test, I expect it will fail.
