How to verify Target after Cloning?

[MrBugs]

Hi @all,

I'm planning to upgrade my iMacs 250 GB HD with a bigger (1TB) HD.
I currently use MacOS 10.4.11 .

The new HD is attached via an USB to SATA adapter tu my Mac.

That for, I first formatted the new HD with the onboard Mac HD tool
(called Festplattendienstprogram in german MacOS), using the parameters
journaled filesytem, create bootable, GUID as suggested by the tool.
I gave the HD a slightly different name as the original HD. To prevent any
problems arising of having two harddisks with the same name.

After that I started SuperDuper!. Using the standard options as suggested
by the documentation (all files, no repair of permissions as it isnt fully
necessary, erase target then copy. do nothing after completion).

I had to do this twice because I encountered SuperDuper having problems
with a file I had tested myself as defective some weeks ago. (Deleted it
and cleaned the trash bin)

The second SuperDuper run was successful, the SuperDuper Result page
showed no errors or warnings.

The next point from now will be to open the iMac and replace the HDs.

And before this I want to make 100% sure the the target HD is working.

I checked both HDs via Infoscreen and found differences.
The original having 149330 folders, 665609 files and consuming 158.0 GB.
The target having 149263 folders, 665060 files and consuming 150.4 GB.

So how can I verify that there are no necessary files missing?

Thanks very much in advance
MrB
