In certain cases, ZAR data recovery software can recover a filesystem without a need to perform a full scan of the volume.
This may provide significant (up to ten times) speed boost compared to the traditional "read all" analysis.
Quick scan mode activates automatically if certain conditions are met.
It works with NTFS volumes only.
If ZAR detects that the data gathered during the quick scan is not enough for a filesystem reconstruction,
it reverts to the full scan automatically.
Quick scan mode is inhibited if any of the following conditions are met:
- RAID or Digital Image recovery run is performed.
- The filesystem type override is in effect and the specified filesystem type is not NTFS.
- The partition to scan is smaller than 8GB.
Default setting is Automatic.
When set to Disabled, quick scan mode will not activate regardless of the volume condition.
You should disable quick scan mode if you are recovering FAT volume which was accidentally formatted to NTFS.
