I do a nightly SuperDuper! clone on my MacBook Pro. Ever since updating to their latest (Lion-compatible) version, it won't do a full clone, but the logs report copy failures because of Input/Output errors. (Unfortuantely, the previous version successfully completed clones, but did not report the errors and simply did not copy the files).

Sure enough, if I try to copy the files it reports, in the Finder or via command line, it also fails. Every time I delete one of these offending files, and try to run a new clone, it finds another file that can't be copied (this has happened three times so far).

Obviously I'm thinking this hard drive is ready to crash, but is there a way to verify? Disk Utility reports no problems.

If this problem started after upgrading SuperDuper!, I'd contact their support people about it. Try downgrading to the previous version first, to see if the problem goes away. –  Eric Jul 14 '11 at 18:19
    
Check the SMART status of the drive for hints as to whether or not the drive's really in trouble..? –  Doc Jul 14 '11 at 18:26
    
@Eric - I did contact them and downgrade, and as I mentioned, the clones complete, but the troublesome files simply don't copy. Support wasn't super helpful, just noted that newer versions can be more comprehensive. –  shanebonham Jul 14 '11 at 19:09
    
@The White Phoenix - SMART status = verified –  shanebonham Jul 14 '11 at 19:36
    
SMART status reporting isn't very reliable; I've seen obviously failing drives (incl. one that sounded like a coffee grinder) that showed SMART status = verified. Other tools (like SMARTReporter, smartctl, or Smart Utility) may be able to get more status details. My advice: freeze the current backup (to avoid backing up more damaged files), get a new drive, and migrate NOW. –  Gordon Davisson Jul 15 '11 at 3:52
