@orekhov,
Unfortunately resetting SMART attribute (knowing how to do it) won't help in this case as reallocation is already in act. You have to get data out of the drive and replace it. I have a certain feeling that imaging can be successful with some effort (i.e. retries).
Try to image first the good parts of the drive, do not make too many attempts on damaged sectors first. OR use different recovery strategies / SW.
If the drive is not totally worn out (i.e. too many micro defects, scratches or non fixable head problems) we can fix it 100%, but I am in Italy, it is not practical to send it back and forth...
Regards !
P.S.
If you get data out and want to try something, simply use MHDD and ERASE the entire drive. Turn off then on , and if you are lucky enough the problems are (temporarily) healed.
Will take a lot of time but it's worth a try. Sometimes Samsungs are smarter than we think
