Are automatic scans faster than scans you start manually?

A little while ago I did a manual scan, and it took over a day I believe for my 11 TB drive. Now I am looking at the scanner doing the automatic scan and it seems to be going way faster. Is that normal?

Yes and no. 

The scan themselves are limited by the drive's speed, other activity on the drive, other activity on the same controller, etc.   But, in general, should be a consistent speed. 

That said, the automatic scans (or really any scan after the initial scan) won't be scanning the entire disk.  StableBit Scanner keeps track of what sectors have been scanned, and when they were last scan.  Manually triggering a scan will still abide by the scan history and scan settings (eg, it won't scan sectors that were scanned less than 30 days ago, assuming the interval for scanning is set to 30 days).   

You can see this sector map, as well as the "condition" of the drive here:

Also, on the left side of the sector map, there are 4 buttons (the 4th may be hidden due to sizing).  But you can reset the scan history for the entire disk (using said 4th button), and rescan the entire disk.  

However, because of how the sector map works, over time it should scan when the drives aren't in use as much, and should break it up over the month. Resetting the sector map will reset this "learning" too.

Ok, thanks.
