I have been running 4.3.3 for a while now, with no issues. Today I tried upgrading to 4.5.6 and one of my data drives shows up as "Unformatted". I then tried to upgrade to 4.5.4 and had the same issue. I have now reverted back to 4.3.3 and everything is fine. Anyone have any ideas? I've got the syslog file, but I have no clue how to decipher it. Plus it's 28 pages long, so I'm not going to post it unless someone asks for a specific part of it.
