No help here... My first guess would be SuperDuper is screwing up, due to the scheduled backups. For example, there is stuff like this buried in the application directory... /Volumes/SuperDuper\!/SuperDuper\!.app/Contents/Resources/com.shirtpocket.backuponmount-login.plist ...but it's undocumented. So, try disabling the scheduled backups, then restart the computer. Hopefully SuperDuper will actually do what it's told. If the problem persists, look around for a SuperDuper log (maybe in /Library/Logs) and also take a look at the Apple System Logs (in var/log, labeled asl) with the appropriate timestamp. The suffix U0 is the kernel, G80 is the user's group, U501 is the user (typically). Look at all of them. My impression is some things logged here don't show up in the system (syslog generated, I believe) log. If posted here, please don't let the lines wrap. And, if anyone wants to include it in a followup, it would be kind to trim 900+ lines (or whatever..) to just the relevant entries. I'm also curious about the drive make, model, and enclosure, but I doubt this problem is related to any of that.
