fijorube@khtyler.com, that is an option in some erasing programs just wipes the first kilobyte of the chosen files... works only on some file types... any zip compressed data with multiple files can be mostly recovered since they include a "central directory" that is in fact at the end of the archive and is normally used by most unzip tools since it is so much quicker to parse the entries in that compact location than seeking through the individual component files zip headers one at a time. Another option is called top and tail erasing where the first and last cluster in each file to be erased is over written as well as the directory entries file name.

ron, Yes, it can help you wipe free disk space to permanently erase already deleted data.

ron, "super" erase is just a marketing gimmick to try and differenetiate this product from the other similar or better erase products at less or no cost out there... and yes any such eraser should have the option to erase free space, they should also be able to erase cluster tips too. Eraser from https://eraser.heidi.ie/ will do that and much more for free.

ron,

I use eraser. It's free, has a dozen different erase methods, and can 'erase' the blank space on any disk. (re-write over blank space).

MP, I am so sorry that it is not portable. We hope improve in next versions.

DoYourData, I made a portable for myself, using Cameyo.

DoYourData, would you mind telling us in what way this eraser program is a "Super Eraser"?

Does it by default simultaniously erase Alternative Data Streams associated with a target file being erased?

Does it impliment the Security Erase prepare/unit ATA/ATAPI command ?

jj juice, if you give or sell me your old computer, with a formatted drive and re-installed OS, I can recover almost all your old data with any of the many giveaways we have seen here. Or with the free Recuva.

Formatted does NOT wipe the original data. It only 'tells' your computer it can overwrite all existing data.

little ricky, you might de amazed.

Many formats, like .pdf and .doc have a characteristic header that can be found. And from there ...

I remember long, long ago I used to replace the two bytes in the header of an encrypted WordPerfect file to make unwanted de-encryption more difficult.

little ricky, When files are deleted from your computer/disk formatted, you are simply deleting the directory listing for the particular file. Even thou it is no longer "visible", the data remains on the disk and isn't permanently removed until it's overwritten with new data. Just re-installing an OS only over writes the area previously used by the OS. Other data remains. The only real way to actually wipe a drive so nothing can be recovered is a complete overwrite of the complete drive, usually consisting of all zeros, except the 511th and 512th byte..those are left with the code that allows the BIOS of an MBR system to recognize the drive is ok to write to. Or take a hammer and nail to it and completely destroy the platters inside.
UEFI and GPT systems are a bit more difficult, but again, unless the complete drive is over written, old data that isn't part of the O/S could be recovered with advanced methods. I had an old drive here that I did a complete format on, but decided to check it

little ricky, who told you that? rebuilding a maliciously erased MBR is not that difficult and even not bothering to rebuild it but using a partition data recovery tool should scan a drives logical surface for partition signatures and glean the partition parameters from each partion it finds and offer the contents for saving to another drive... or use of a simple deep scan and just find known file header structures and depending upon algorithm used recover the data with varying degrees of success.

Duane, I usually have to pause my anti virus to install this site. works. for me.

Gb, Whenever there is a giveaway for both Apple and Windows, the setup.exe for Windows is not encrypted an running it will not trigger your AV into reacting on a false positive.
