I have my WD My Cloud 2TB since several months without issue so far. But when I come back from vacations last week, nothing was working properly. I am working on it since and I can say:
the self test (short and long) are returning no issue, so the disk seems ok (?)
After a reboot, the NAS is working ok if I do reasonable transfer but as soon as I tried to copy lot of files in the same time (from my Win Vista PC), the bitrate goes dramaticaly down (few ko/s) and after a while it stops saying he cannot access one of the file. Trying again and again make often the NAS to disconnect: I do not see it anymor from my Windows PC.
May-be an issue with latest FW?? Is there someone experimenting the same thing?
Thanks for any hint
