Stop the defragmentation before you turn off the PC or you risk losing your data.

Forcing your PC to power off while defragging the hard drive can leave your data scrambled and unusable.

Can I stop defragmentation in the middle?

Defragmenting your hard drive can be good or bad for the device depending on what kind of hard drive you're using. ... Defragmentation can improve data access performance for HDDs that store information on disk platters, whereas it can cause SSDs that use flash memory to wear out faster.

How do I know when defrag is finished?

Can I do other things while defragmenting?

Yes, you can indeed and there are no risks. The Mcirsoft defrag APIs (the code that does the defragmenting) is 100% failsafe.
