If you need something more versatile then look no further than "Eraser" aka "Heidi's Eraser". Whether there is data, in "FREE Space", or not it overwrites all Sectors in "FREE Space" with ones, zeros, or ones and zeros also with the option of three or seven passes. It will not touch any of the data on your drive except any data that might be in "FREE Space". In other words the data for the file you've deleted now becomes free space, but the data is still there until it is over written.Īnd so the second thing "MDWP" does is over write "FREE Space" on your disk. When right click on a file and select delete it's not deleting all the data for that file it only deletes the location information on the disk and there that data sits until it is over written. Now lets suppose the Librarian wants to remove the book your looking for off the shelf, but instead all the Librarian does is remove the location card from the index file cabinet the book was not removed off the shelf only the information that tells you where to located it. When you load any data program, file, etc your disk has to find out where the data is located and it looks in a catalog type file to find that information. To find the book you want you have to look in the index to find out where the book is located your disk works in the same manner. To help you better understand let's go to the library and check out a good book. When I use the term disk I'm talking about magnetic type disks, not an SSD or similar type devices. For those that don't know why it does that it writes the ones and zeros to dramatically increase the chances that the data it erases/deletes is permanently erased and cannot be recovered.Īgain, for those that don't know, when you delete anything on a disk the data that you delete remains on your disk until it is overwritten and even then it may still be able to be retrieved. It's a pretty simplistic program in that it will only perform two functions Wipe an entire drive replacing all sectors with ones, zeros, or ones and zeros with three or seven, military grade, passes. I've used a Forensic style deletion, eraser tool for many, many years and so I didn't need "Macrorit Data Wiper Pro (MDWP)", but installed it on my XP system to see what all it would do.
