So, when I first bought my PogoPlug (arguably without reading any documentation etc.) I slapped my Drobo on it and started copying files up to the drive and life was good.  The next day I went to access the drive and found that I was no in read-only mode and the help box that popped up was blank.  I've seen some chatter that HFS+ is not supported, but I suspect that's old news or something else is up because clearly I had no problem using the Drobo at least at first.

Having gotten nowhere with the Drobo I disconnected it and went with my old 300GB Maxtor One Touch, and it too has been working fine for over a week.  Suddenly last night the drive showed as being blank in Finder.  The first thing I did was "re-load" the PogoPlug and it now shows as "Maxtor One Touch II" when I had renamed it to "PogoDisk", and is still showing up blank.  When I log into my.pogoplug.com it now says my disk is not supported.

What in the world is going on!?  Any advice/input/support is much appreciated!
