3.4. Performing a Drive Scan

Before you start data recovery or search for files and folders, the hard drive must be scanned. Scanning uncovers areas of the hard drive that may contain deleted files. If you are searching for a deleted partition or logical drive, read the instructions in Performing a Device Scan.

There are two types of drive scan, as described below:

  1. Basic Drive Scan is a quick and general scan. Most of deleted files and folders can be found with this type of scan. Try this scan first [Enter]
  2. Advanced Drive Scan is much slower as it processes the entire surface of the hard drive, detecting all possible clues that may reveal deleted data. If the Basic Drive Scan does not reveal the files you are searching for, try this scan next [Ctrl]+[Enter]

After the cursor is positioned over a logical drive, press [Enter] to scan that drive with a Basic Drive Scan

To stop (cancel) the scanning process, press [Esc] at any time.

After completing a drive scan the screen displays the areas where data may have been deleted, similar to the figure below. Deleted files or folders are marked grey.
