Our forensic unit in collaboration with others have decided that if a drive has over 5% of bad sectors then they have to report it to the investigator.
Would you be able to run that calculation and output the percentage in the log file e.g. 'there are a total of x bad sectors which represent n% of the total sectors reported'.
For units that do not require this calculation it could give them a clearer picture as to how much of the drive is unreadable. It is much more impactive to see that 25% of the drive is unreadable rather than sectors x-y
