Looks like the card is properly recognized, and I'm pretty sure I've used 
AHA2940U cards under YDL 3. Is it possible that your SCSI chain is 
unterminated? (Would that even be an issue if the SCSI drive is off? Not 
sure, but suspect so.) If that's not the problem, could you have a bad SCSI 
cable?

You'll have to fsck the specific filesystem, rather than the device as a 
whole. So in your case you'd want to do "fsck /dev/sdc3".

Hope that helps,
