OVERVIEW OF CHECK BAD SECTOR

A bad sector is a sector on a computer’s hard drive that has been damaged and
has lost the ability to write and retrieve data. Bad sectors can sometimes
corrupt your saved data as well as slow down your computer. In order to improve
the performance of your computer, you can use the Check Bad Sector function to
make sure that you hard disk has no errors.

AOMEI Partition Assistant also provides the feature to check bad sector for your
disk or partition. However, this function can only find the bad sector not
repair it. There are dozens of ways to fix bad sector, the most effective one is
to subdivide the bad sector into an independent unallocated space or use other
repair tools.
