Description

Add a non admin restore to delete utility for unused space.

By this I mean add a simple utility to reassign all unlisted files a new listing in a temporary file location.

After restoration to a either user defined location or a preset location for each drive (?:\!\Restore2Delete) the files would be erased or sent to the Recycle Bin to be erased(?:\$RECYCLE.BIN).

To be specific I am referring to erasing "Unused space on drive"

I would like to add back deleted items to the table which lists regular files that have not been deleted.

I would like to do this to properly erase them without erasing the entire drive.

In Vi$ta Admin is required and it still will not work for me eraser crashes at 2 percent.

Another solution to remove the need for admin access is to fill the disk with deletable files then erase them all at once or in chunks.

I would like it if a utility to fill up the disk could be added to Eraser so the Admin requirement to erase "Unused space on drive" could be avoided and the space erased none the less.

An example of a utility for filling the disk is FillDisk? v0.02 which fills all available space so that it can now be erased without admin access http://www.cylog.org/utilities/filldisk.jsp

  • Type changed from defect to enhancement
  • Milestone set to Eraser 6.1/6.2

Listing deleted items is heuristic and will not guarantee all deleted files will be cleanly erased. This means that though a file is on a disk, it will not be detected and thus not erased. If you want to avoid this, erase files and don't use the recycle bin.

Administrator rights are required because as a standard user Eraser cannot touch the cluster tips of files not belonging to you (including all program files) which is dangerous since you will enhaust all space on the drive with multiple copies of program files with their cluster tips erased (which will then be ignored). In practice, Eraser already fills the disk with files and deletes them for the full space erase.

FillDisk? will do the same as what Eraser does, except that it probably does not have:

  • A PRNG to ensure plausible deniability
  • Cluster tip erasures
  • Directory structure cleaning
