Surface Test

This function is used for checking bad sectors on one partition. It checks partitions not by "clusters" and doesn't label out the bad sectors on one partition. Partition Table Doctor will check every sector and display when it found a bad sector. While complete, a bad sectors list file surface.txt will be created. When the Surface Test checks out up to 10000 corrupted sectors, it will stop testing in order to prevent disk from destroy.

Note: If Partition Table Doctor tests the partition very slowly or finds many errors, we suggest you cancel the test and send your hard disk drive to local data recovery manufacturer.
