Drive loss after FW update

My Cloud OS 3 Personal & Network Attached Storage My Cloud Pro Series

Hi all,
Upgraded a new PR4100 last night with 2.31.183 - on re-boot it reported Drive 3 as Bad.
Tried a replacement in Bay 3 and still marked as bad.
Box had been running 24 hours on test prior to FW upgrade.
NAS is new as are the drives; feels like the FW broke something.
It’s an SG Ironwolf in bay 3, Bay’s 1 and 2 are WD Red’s (I like to mix them up in case of batch faults)

Is there a source for a downgrade on the FW as the “Out the box” seemed stable…?

Many thanks, Pete

Hello dougle,

It is not recommended to downgrade the firmware as it may cause further issues with the device.

You should perform full test on the device to diagnose the issue with the drive by referring the link mentioned below to look for the issue.

IF you have manually updated the firmware, it is recommended to stop all processes and save all your data before performing the firmware update and the devices require a hard drive inserted into the bay and a volume must be created to perform the firmware update.

However, you should contact WD support in order to isolate the issue if you have already performed the full test on the drive.

To contact WD support, refer to the link mentioned below.
