Users on disk other then Macintosh HD
 

I'm running into some trouble backing up my MacintoshHD since moving my /Users directory to another hard drive. I can back up /Users which is now on a hard drive named Data without any problems but when I try to back up my Macintosh HD, which contains OSX and apps (everything except for /Users) the back up hangs. I tried writing a script to ignore /Users but the back up would still hang. I'm guessing that SD is hanging because it can't find the /users directoty. Is there a workaround?

A missing Users folder wouldn't cause a problem. Are you sure it's hanging and not just copying something large?

To check, get to the point where it looks stuck, and then run:

in Terminal. The last two lines are what we're copying at the time, and should help figure out what's going on.

No it does seem to be some sort of lock up. SD reads:

Copying files from Macintosh HD to OSBackUp
437 of 414,990 files evaluated, 386 files copied. Effective speed 15.25MS/s
91.69 MB evaluated, 0.00 MB a;ready up to date, 91.96 MB copied

It reached this point after about 40 seconds. 10 hours latter there has been no progress. Here are the last few lines of the cmd line you asked for:

Finaly clicking "Stop" locks up my computer - spinning wheel - and I have to hard reboot. OSBackUp is the 2nd partition on an external firewire drive. It is formatted as OSX journaled. I do not have any problems backing up /Users to DataBackUp which is the first patition of the Fire Wire drive.

That would indicate that you likely have a bad sector or other disk damage in your /usr/bin/folder...

I assume you mean a bad sector on the source disk not the destination disk. Is there any software for detecting and repairing bad sectors?

That's what I'm guessing, yes. I believe TechTool 4 will detect bad sectors, though I'm not sure... you could also try an archive-and-install and then delete the previous systems folder...
