Scanning drive, at 60%, check 8 hours later it's back to 13%

[HTWingNut 1]

I installed a new 8TB hard drive. I started running Stablebit scanner on it. When I went to bed last night it was at about 60%. When I got up this morning, it was back to 13% checking. No indication of any errors or bad sectors. What could cause this?

This is normal.  

The percentage isn't based on the whole drive, but based on what is needed to be scan.
