I all of a sudden started gettting all kinds of errors writing and reading from my CF card... I thought I had it figured out, but I guess not cuz it keeps happening... I'm not ready to chalk it up to 2.10 yet, cuz i thought maybe it was just a coincidence that it started around the same time I installed the new os, but it seems a lot of other people have started getting funny errors readng or writing data... I'm trying to figure it out, I'll post up if I find out anything.

I've had this happen once on a file that worked fine with 1.07. Only the once though.
