Hello baltwo
=> You will find the rest of the report just below after the complementary following informations:
=> I have some news: I located and identified the corrupted files which freezzed my iMac when copied/read/scanned...etc by softs such as Time Machine. Indeed, dragging on the backup drive the folders containing these damaged files, progressively, I identified them because the last (sub-)folder (on the backup drive) containing one of these files, and the corrupted file themselves, had, as modification date, the date of the backup: 'today, …' Then, I deleted or repaired them with, for instance, the 'MP3 Scan+Repair' app in case of audio mp3 files. Other files I found such as certain .dmg or image files were deleted because of not importance. For pdf files, some of them were successfully opened by the Preview app and saved imperatively under a different name. It was a long process… Certainly, it exists an efficient UNIX set of commands using the Terminal app and doing the same.
=> Furthermore, after deleting these damaged files, I used a demo version of 'Data Rescue 3' in the 'Analysis' 'quick mode'. I scanned the internal iMac drive/partition I wanted to backup. It shown a very repetitive set of addresses of damaged blocks ("green curve of time analysis above the red line"). I must mention that the "Scan Volume for bad blocks" analysis I made with a demo version of 'SpeedTools Pro' installed on a partition of another external drive with a basic functional OSX system version of Snow Leopard produced a crash of the computer! Moreover, running 'Data Rescue 3' in the "Analysis" "medium mode" rather than in the "quick mode" produces a freeze (rather than a crash) of the computer as well!
=> Hence, the problem was not specific to Time Machine but affected any soft reading/scanning certain files or blocks. So, deleting the corrupted files did not solve the problem of freezing when proceeding to backups as I expected. Possibly, the corrupted files had allocation blocks common to the bad blocks of the driver and therefore the latter must be fixed or repaired.
So, since I was quite sure it would not produce a crash/freeze of the iMac, I did a complete backup on my backup drive with the Terminal utility entering the following set of commands in my administrator account:
> sudo cp -pRP /name_folder/* /Volumes/Backup_HD/name_folder
where "name_folder" is the name of a folder at the root "/" of the internal (iMac) drive partition. I did not enter the command:
> sudo cp -pRP /Volumes/* /Volumes/Backup_HD/Volumes
because, even if the P option avoids to copy the targets of the symbol links, it did not apply for the specific symbolic link contained in the 'Volumes' folder and pointing toward the backup drive. I was faced in this particular case to a loop hole copying the copy of the copy … of the copy of the content of the backup drive…
Unfortunately, another freeze of the iMac occurred again applying one of these commands and contrary to what I thought! Actually, It was due to another corrupted file I did not find previously, a pdf file, identified easily because the backup stopped at this file. To locate it in the folder hierarchical tree, I used again the procedure described just above when dragging the folders on the backup drive.
Then, I did another backup process with the command line:
> sudo cp -npRP /name_folder/* /Volumes/Backup_HD/name_folder
(with option '-n' to not overwrite the already copied files on the backup drive and gain time)
Then, with the 'Disk Utility' app, I did a "zeroing" of the 'free space' of the internal drive to fix the bad blocks; crossing fingers… that the internal hard drive of my iMac was not "hardware damaged" itself. Then, I launched 'Data Rescue 3' again and medium and deep analysis of the internal partition did not freeze my iMac contrary to the first runs. Actually, zeroing the free space certainly updated the G-LIST of the internal disc's map and fixed the bad blocks without, nevertheless, repairing them as the analysis graph given by 'Data Rescue 3' indicated:
But also, the velocity and the reactivity of my iMac was recovered; a true revival!
==> Then, I installed 'SMARTReporter 2.7.3' and perhaps, also 'smartmontools' in background (?).
Recently, SMARTReports gave me the following report:

Also, is it possible the physically repair the bad blocks with a specific soft/app?
What could be the UNIX set of commands for all these processes?
