Data Recovery

Hard drives fail all the time. Eventually your hard drive will fail and your data
will no longer be available. Ron Austin of
Action Front Data Recovery Labs
joins the geeks for a discussion on how data can be recovered from “dead” hard drives.


Data Recovery is the process of getting data off of a hard drive or some other storage media when the media has become unavailable. It is essential that you do regular backups of your data, because your media will eventually fail.

Every week we cover a bit of the Geek news. Jeffery Los Gatos What is the Windows Update to Patch “BugBear Virus” volnurability? To protect your self from this new virus go to Microsoft Security Bulletin MS01-027, read the bulletin and install the patch. You need this patch if you are running Windows with Internet Explorer 5.01 and 5.5. Jeffery recomended using a second harddrive as a backup. The guest and the Geeks agreed, but exterimaly important documents should be backed up and taken to a second phisical location. Ted Corralitos Ted Emailed us and asked: Hi Guys, It’s Ted from Corralitos again, can’t get to a phone right now… I am wondering if I do something like
  1. dd if=/dev/zero of=/dev/hda
    and write NULLs to my hard drive, say just one pass… Is it possible
    to recover the data I just “wiped”?
Ron sais no, but Miles recomends writing random data, not just nulls. Also two or more passes, for the paranoid, is helpful. Zoe Monterey Can you recover data from a reformated hard drive? You can recover from a high-level format (quick pass), but not from the, less common, low-level platform.
