After persisting with the WD firmware and being under the delusion that WD would fix it, I have finally given up and I now run it with a basic level of Debian, with no WD software running at all. I followed Fox_exe’s instructions here.
To anyone interested, I use the My Cloud as a replacement for Dropbox and I have 2 PCs here. Some days I need to upload ~200 photos and sometimes need to edit them prior to uploading to the web. The scanning process that ran got its knickers in a twist, crashing the database and initiating a rescan. During this time it dropped off the network, sometimes for several hours.
To those who point out that I have invalidated the warranty I say “Which is better? A device with warranty that doesn’t work properly, or one without warranty that does?”
