I just want to report that I'm having the same problem after running the root upgrade on my Droid Incredible. I can't access the software on my SD Card. I can't install from Market for software that is on the SD Card. Titanium can't restore. I can access the files using file explorer. Should I try offloading the drive/formatting fat32/and putting everything back? If not, I will try the procedure to go back to straight 2.2 when I come back from some errands later today. While it is very possible that there is an issue with my sdcard, I have not had one up until now. Any other possibilities? This is just after I rooted then moves a bunch of software to my sdcard. Is it possible the sdcard move does not perform properly? I wish I had done more testing after rooting but before moving software to my sdcard. Oh well...Any other helpful troubleshooting tips would be appreciated. And I do appreciate all of the hard work that goes on here with rooting/roms. Thanks so much!!!
