February 3, 20188 yr I've had a red X pop up on one of my disks. I've been able to move the data to other drives with unBalance and I have replaced the SATA cable. Can someone take a look at my diagnostics and let me know if it's OK to rebuild or shoud I just replace it? If it needs to be relaced, it is possible to remove it competley (it's currently emty), Edited February 3, 20188 yr by emmcee
February 3, 20188 yr Author Of course, it would help if I posted the diagnostics... tower-diagnostics-20180203-1612.zip

February 3, 20188 yr Community Expert These are a very bad sign on WD disks: 1 Raw_Read_Error_Rate 0x002f 200 200 051 Pre-fail Always - 2843 200 Multi_Zone_Error_Rate 0x0008 200 200 000 Old_age Offline - 12 I recommend replacing it
February 3, 20188 yr Author OK - good to know. Is it possibe to remove a failing drive completley without relpacing it? I found this article on the wiki which explains how to remove a drive, but it says: Quote This method can only be used if it's a good drive that is completely empty, is mounted in the array, and can be completely cleared.
February 3, 20188 yr Community Expert Disks in that state tend to error mostly on reads, you should be able to clear it and then remove, but if there are write errors you'll need to use the other method, remove the disk, do a new config and resync parity.
February 3, 20188 yr Author Great. Thanks for the help. I'll run a parity check overnight and attempt it tomorrow. Edited February 3, 20188 yr by emmcee

I've been able to move the data to other drives Just thought I would mention that this is not really the best first action when you have a disabled disk. Moving to other disks in the array is doing a lot of writes to an unprotected array. And just rebuilding would have saved your files anyway.

Anyway, luckily for me parity check has completed without error and I've kicked off the clear script. Thanks all for the help!
