Here is the kind of kernel panic I obtained.

 

 

I have a iMac with a 500Go internal HD and an external 500Go HD formatted with the Disk Utility.

The latter HD was partitioned in two partitions with the "Disk Utility": a 15Go partition onto which a basic OS X 10.6.4 system was installed with the installation disk, and a second empty partition of 480Go.  Moreover, on the 15Go partition, I installed a demo version of the "Speed Tools Pro" soft to proceed scans on the iMac internal HD. Indeed, I suspected problems with bad blocks or corrupted files on this internal drive because I was absolutely unable to proceed to backups of the internal HD with Time Machine on the second external partition because of systematic freezing during the process. Then, I booted on the external HD from which I launched the "Speed Tools Pro" soft to verify bad blocks on the internal HD. Then, crashes occur quite systematically after 75% of the scans. Moreover, because every complete backup (certain partial backups are possible) on the second external partition fails with Time Machine, I followed all of the verifications advised by "pondini" (http://pondini.org/TM/Troubleshooting.html) but without success.

Here is the report for one of these crashes involving  com.apple.iokitXXXX files and which may indicate driver problems with the external HD:

 

 

Thus, from what those problems of crashes during backups of the internal HD or scans/reading of files could be due?

Also, I am unable to make backups of my iMac.

    Also, is it possible the physically repair the bad blocks with a specific soft/app?

    Launch Disk Utility and erase, reformat, and select the zero out data security option. AFAIK, that'll isolate bad blocks. Bad blocks can't be repaired, just excluded.

    What could be the UNIX set of commands for all these processes?

    diskutil is the Terminal command for all of Disk Utility's operations.
