Verify Disk in Disk Utility freezes the system

[___]

I made a copy from my mbp on an external hd.
After an update problem in the original internal hd
I restored the image seamlessly (sigh) except for one thing.

I can verify with Disk Utility
neither the internal hd when booting from it
nor the external hd when booting from it.
The system crashes (almost) immediately.

It is possible to verify the external disk
booting from the internal and viceversa.

I'm using SuperDuper! 2.1.4 v82 on osx 10.4.11 .
I repaired both disk and permissions with no results.

Any hints?

The system crashes? That's weird, certainly. Do you get a kernel panic? Anything interesting in the panic.log?

Dave,

fortunately after verifying the hd
with Disk Utility I left the mac running
for a while and got

Verifying volume “Mac HD”

Checking Extents Overflow file.
Checking Catalog file.
Incorrect number of thread records
Checking multi-linked files.

(It should be 5723644 instead of 5723642)
The volume Mac HD needs to be repaired.
Error: The underlying task reported failure on exit

after repairing the internal hd and the clone
everything went fine (I missed repairing...)

Cheers...

one more thing...
verifying the disk just takes too long,
and the system seems to have crashed,
then I can do nothing before it finishes,
I don't know if this an issue or not
on a 111GB hd (89 used),
probably it needs to be defrag,
any ideas?

It's pretty weird that it would crash like that... but if your copy went OK, I'd probably start up from your OSX DVD and erase *AND ZERO* the drive. Once done, then restore your (checked, yes?) copy and go from there.
