Check drive
In the Ribbon bar under Check drive, you have the possibility to check the drive for errors. You can find the corresponding report as usual under Schedule the tab Reports. Checking the drives corresponds with the Windows chkdsk function, yet, it only can run scans in the read-only mode, and thus cannot correct errors. In case of error, you need to run the chkdsk command manually.
It is strongly recommended to thoroughly check a drive if an error is detected. More information can be found in the Windows Help file.
You can cancel the check by clicking on stop in the Ribbon.

Thin Provisioning
Thin Provisioning is a process by which virtual machines can allocate available space as needed. Doing this reduces power consumption, space requirements, and the amount of heat generated. O&O Defrag supports Thin Provisioning by reporting changes in the amount of space needed, especially lower amounts of space needed, to virtual machines which then leads to a reduction in the allocated space. This results in less space being needed in the future and less wear on resources.
