For no obvious reason all my shares on my MyCloudMirror 4TB,setup up as 2xJBODs, disappeared. I had done nothing to cause this no firmware update etc…
I did a System restore and all the shares except one reappeared along with data. The missing share named John was empty.
I used DiskInternals Linux Reader software to see if anything could be recovered. No sign of the missing data except the folder .wdmc actually contained a share(?) John2 which had all the expected data folders for the share John but their files were designated as transcoded files and there was nothing to recover.
Any suggestions?
