Check Partition and Fix Errors
  • You can use chkdsk.exe to check the partition that has a drive letter only. For the partition with no drive letter, you need to assign a drive letter for it before using chkdsk.exe.
  • Depending on the size of the partition, this process might take several minutes.
  • As for Check whether there is bad sector on the partition, the operation steps are also similar to those two involved above. The little differences are that you need to choose Check whether there is bad sector on the partition in the second step and when you click OK, a window will pop out to let you confirm the decision you have made. At this moment, you just need to press Start button to begin the operation. It will show you how it is going and many details such as where the bad sectors are located and how long the time it has already taken. This option is the fastest one of the three. Besides, it will be faster by ticking Quick Check in the pop-out window.
  • You'd better close all other running programs when checking partitions with AOMEI Partition Assistant because they might be closed accidentally if AOMEI Partition Assistant recognize them.
