Description of Percent Complete Values in Disk Defragmenter (131648)

MORE INFORMATION

The following table describes the meaning of the values in the Percent Complete status bar:

   Value      Description
   ----------------------------------------------------------------------
   0%-4%      Defrag is running a special version of ScanDisk for Windows
              to check for errors before doing anything with the disk.

   5%-9%      Defrag is making a "road map" of the best locations for the
              data on the drive which it will use when actually moving the
              files.

   10%-100%   Defrag is moving the data on the disk.
				

On a drive compressed with DoubleSpace or DriveSpace, the following meanings apply:

   Value      Description
   ---------------------------------------------------------------------
   10%-49%    This is the first optimization pass through the compressed
              file.

   50%        Defrag is checking the internal compression structures of
              the drive.

   51%-100%   This is the second and fastest optimization pass on the
              compressed file.
				

If the percentage jumps from 0 to 5 percent without any drive activity, the Check Drive For Errors option is probably not enabled.

The ScanDisk activity from 0 to 4 percent occurs only when Defrag is started. The ScanDisk activity is not repeated if Defrag is forced to restart because of disk activity.
