Hello,
I recently had a HDD fail and replaced it with a new one of the same make and model. Since the rebuild the status LED on the front for that bay has been red. The Drives page says the drive is good. Any suggestions?
Assuming the hard drives have been properly initialized, they should be checked for errors. To verify the hard drive type and S.M.A.R.T. status, use either of the following options.
Option 1:
Install the “Get S.M.A.R.T.” app for My Cloud OS5 NAS devices, available from the list below. The preformatted results can be easily copied and posted to the forums for further analysis if desired. The “Get S.M.A.R.T. ” app also updates the smartctl database and reports the drive self-test status.

Option 2:
Enable SSH, then run the following commands, one at a time. The results can be easily copied and posted to the forums for further analysis if desired.
smartctl -a /dev/sda;smartctl -a /dev/sdb;smartctl -a /dev/sdc;smartctl -a /dev/sdd;

Disk 1 is the one with the red LED.
Disk 1 shows no obvious signs of problems. Note that disk numbers do not necessarily correspond to slot numbers or locations.
Disk 3 uses SMR technology, which is not suitable for use in RAID arrays.
Disk 4 is failing.

Thanks for the info. Looks like I will be ordering new drives.
You should create backups prior to swapping drives and doing multiple RAID rebuilds.
Also, I made a minor change to the “Get S.M.A.R.T. ” NAS app, so disk numbers should now correspond to the actual slot number or drive bay. Simply download and install the app again to see the new results. In your case, I suspect that disk 4 is actually the HDD in bay 1 with the red LED.
