Yeah mine has taken around 20 minutes so far and the bar is still only one pixel wide. I too have two drives but I doubt that is the problem.

The drive indicators show only the right hand drive (the secondary I guess) as spun up but not being read.

I can definitely hear the heads moving about though.

....Hang on ... all of a sudden it's about 85% done now although it seems to have slowed down again. Drive indicators show the same status. At first I thought it was trying to convert the file system into the new format but the release notes would not indicate that.

Oh well it's onto rebuilding the database now. About 30 minutes is probably about right for a fsck though on my total 70G machine.

It would seem that emplode forces a fsck if it detects an upgraded unit.
