Fix - overwrite Current_Pending_Sector

can this be used to fix (overwrite) only the faulty sector without data loss in a running SW raid1 system?

Num  Test_Description    Status                  Remaining LifeTime(hours)  LBA_of_first_error
# 1  Short offline       Completed: read failure       90% 2272         1046343

dd if=/dev/zero of=/dev/sda seek=1047343 count=1 

just the 3 pending sectors … no other errors are reported
