Scrubbing data

Helpful Hints, Warnings | Posted by Dennis April 24th, 2012

Did you know that deleted files aren’t REALLY deleted?  Normally, even if you remove a file from the Recycle Bin in Windows, it only removes the first bit of the file, the rest stays intact.  So if you’re getting rid of an old PC, for example, a savvy user can pull up things you intended to delete.  The answer?  File Scrubbing.  This is a method of going through the free space on your drive and re-writing it several times with 1’s and 0’s.  I found a great, free, utility that does this called Summit HDScrubber.  You can get it here.  Of course, you also need to watch out for hidden files, and other stuff.  Before you scrub, remove your Windows account and the data in it.  If you’re just going to throw the PC away, you can always just remove and pound the hard drive with a hammer.  :-)

Deleted files

Helpful Hints, Warnings | Posted by Dennis November 16th, 2011

Sometimes we make mistakes.  It’s pretty easy to accidentally delete a file.  Of course, windows can help right away if you check your Recycle Bin (or Deleted Items in email).  But what if those are gone, too?  This is one really good reason to BACK UP.  But if you don’t have a backup, what then?  TURN OFF YOUR PC and CALL a PROFESSIONAL.  We have tools that allow us to find and restore deleted files, but the longer you run Windows, the less likely we’d be able to get it back.  See, when a file is deleted, just the first part of it is lopped off.  The rest remains intact until it’s written over.  The longer you run Windows, the more likely that space will get written over.  Note that there are forensics tools that the FBI and other labs use that can retrieve many layers of the magnetic writes.  It’s a lengthy and sophisticated (thus Expensive) process though.  If you WANT to totally remove sensitive files, then use a software SCRUBBER.  It erases, completely, and many times so that this type of retrieval is much more difficult if not impossible.
