Safely Partition
Check your partitions and see if there are any errors. (Mandatory)
For the partitions which you are going to make changes, for example, if you want to extend drive C by shrinking drive D, please check if they have any file system errors. It’s very easy to check the errors. Just right click on the partition you want to check and in the pop-up menu, choose Advanced -> Check Partition -> Check partition for errors by using chkdsk.exe -> OK like in the following pictures:

If there are some errors existing on the partitions, the program will automatically ask you to fix them. All you need to do is to follow the instructions and complete the check and fix operations.
Commit and perform the tasks one-by-one (Optional)
AOMEI Partition Assistant allows you to do multiple tasks all at once. For partition the hard drive more safely, the best way is: click the “Apply” button to commit the operation to the physical hard drive every time a partition operation is completed. This is fast and simple.
Every task you did on the partition will be added in the “Pending Operations” first. We suggest you to click the “Apply” button on the toolbar immediately once you see there’s a task pending in the “Pending Operations” like in the picture below:

If possible, please avoid clicking the “Apply” button when there are already too many tasks pending. We do not suggest our users to perform too many tasks all at once. It’s more advisable to perform the tasks one-by-one.

Do not forcibly terminate the tasks or cut off the power (Mandatory)
First, please don’t cut off the power while performing the partition operations. Second, if it’s a laptop, please make sure the power cord is connected properly for charging the battery.
Among the three steps above, step 1 and 3 are mandatory. Step 2 is optional, so it depends on your situation.
