I have a Western Digital 2TB My Book Mirror Edition and one of the drives in a RAID 1 config has become ‘degraded’ according to the WD drive manager software. The LED on the front of the unit is flashing bottom half / top half alternately.
I have ordered another drive the same…
I cant seem to be able to work out which of the two drives is faulty though?
Please can you tell me how I work this out?
