Difficult to say without more information.

Please attach your diagnostics to your next post.

Hi i was told to switch sata cables around to see if it solved it, so stopped everything and shut down server swapped the cables around and rebooted but kept the dockers stopped but now have a red X against a disk, so shut it down again till someone says what to do ?

Thanks

Once a drive is disabled then it will stay in that state until it is rebuilt.

 

if you try and start the array in normal mode with the drive disabled then Unraid will try and emulate the drive contents using the combination of the parity drive and the other data drives.   When you do this does the emulated drive appear to mount correctly and show the expected contents?

Thanks but a newbie with unraid, so are you saying start the server and the array starts automatically,  which i have now done, but this drive still shows with the red X . i can go into the drive and the folders are still there with contents showing

 

update stopped the server shut down and made sure to swap the cables from this drive and still the same

Please post the diagnostics after starting the array in normal mode.

this is after a clean start after shutting it down

SMART looks OK, some UDMA CRC errors so suggest replacing the SATA cable, then and since the emulated disk1 is mounting and assuming contents look correct you can rebuild on top.
