@ cpt paranoia:
Your advice was very close to the solution. For the system factory restore, you need to unplug the device from power supply, then push the reset button, plug in the power and keep the reset button pushed for 40 seconds. Now I can access the device.
(I finally reaches a support hotline: Their excuse: “oh, it seems we have a telephone problem since tow days” come one!!) But no feedback so far on the support case I created two days ago.
However: The reset created new folders with the old ones in the new ones. And: NO ACCESS to the old ones.
So I have to reformat the whole thing and start all over again:
Lessons learnt: WD to me is an absolutely unreliably storage device, the technical support is a nightmare and I would never buy it again!!! Maybe a nice toy to move around files with family and friends at home. But not a backup system I do trust.
Sorry; I thought you might have read the manual and understood that a ‘40 second reset’ requires unplugging power. You seemed to know your way around, and it’s had to get the level of detail right.
Restart the Twonky media server; that should recreate the those folders, if that’s where you want to do. I try to avoid them if possible, because I find they give me trouble.
Or simply use a file manager on your computer to access the drive and create the folders.
