Can certification fix a drive that was predicted to fail

SoftRAID advised SMART predicted one of my hard drives would fail with 16 unreliable sectors. So I certified the disk with 3 passes (took some time); initialised the disk and then validated the disk. SoftRAID now advises that the disk has been verified successfully and that all sectors on the disk are readable and the disk is functioning normally. I am wondering what SoftRAID did to repair the disk as I dont think SoftRAID has a repair function.

SoftRAID does not "do" anything, this is the drive. Certify is a low level script that writes/reads complex patterns to disks. Nothing else.

Reallocated sectors are permanent.

Unreliable sectors can happen from power brownouts, etc, and if the drive can prove to itself they are read/writeable reliably, the drive will change the status to normal. that is likely what happened.

When a drive has "unreliable" sectors, a certify is what is recommended, either the drive will reallocate the sectors (meaning you should replace the drive in our opinion), or correct the state, where you can assume the drive is OK.
