I have the invalid, "Drive full" error. From other reading on this forum, it's caused by a firmware glitch which was supposedly fixed last year. I checked my CloudStor and it says it's running version 3.0.3.30 as of the date of this posting. I have been searching for some version history and/or instructions on how to change firmware versions, but can't find it. How do I change versions of CloudStor Firmware, and which version should I change to?
