I bought my MBL just before christmas and I immediately upgraded to the latest firmware. At first it seemed to be working very fine, rather quick compared to my old NAS. But then I switched it on one day and I notied that the led looked as if it was white and the status, seen in the UI page, changed to bad. After fiddeling around, maybe also a restart, it went back to status good and I could access it again. A few days everything was ok and then it started again. I was always able to access it again but this should not happen. I use osx lion, latest version and safari for the UI. What can this be? Any suggestions are appreciated.
