Odd size issue...
 
Ok here is my odd issue...

I have a 160gig secondary internal harddrive with 140gigs used. I bought a 200gig USB2.0 HD to backup my internal to so I could start the new year with a blanke slate.

Now I ran SuperDuper! yesterday and it took pretty much ALL day to work, in fact when I left work after my normal 10 hour day :P it was still running. I came in this morning and my computer was locked up. So after a hardreboot I go to check the drive and it has all the files a-z plus the files work and everything seems to be fine...except that there is only 50gigs used when my internal has 140gigs used. What are the reasons this might be happening? how can I compare the drives files to each other to see if everything is in sync? I formatted the external with OSX Extended just like the internal.

Wonderful product you have here by the way, I looked at CCC and a syncup and a few others and still liked SuperDuper! the best. Keep up the good work.

Hi, Matthew.

A few things could be going on here. First, just because you've got a USB 2.0 drive, doesn't mean that you're running at USB 2.0 speeds. I'm guessing that it has stepped down due to a slow device on the same "bus".

But, if your system crashed, it's quite possible that a low-level driver/kernel extension is interfering with copying. This is almost always some form of AntiVirus, that's attempting to scan every file copied to the external -- slow and, due to bugs in those scanners when confronted with a large number of files, buggy.

So, if you have AV on, disable auto-protect. Then, use Smart Update and re-copy -- SD! will compare the two drives and reconcile the backup, adding any missing files.
