Thanks for the reply, and the tip re: the recovery.log. I've got a copy and it's posted below. Again, sorry for not being able to use pastebin:

I should note that when I rebooted into COT to grab the log file, the message about not being able to mount my SD Card was again displayed, but the recovery performed as if it was mounted. I was able to view the different partitions and enter the Storage Management area, view existing Nandroid backups, etc. Maybe the warning message is just being displayed in error?
