How To Sanitize A Hard Drive

For non-Solid State Drives (SSDs) I would use a tool like the open source TrueCrypt full-disk encryption. Using the software you want to encrypt the entire disk, including all system partitions, and then change the key to a very long random string. Then format the drive. If you put sensitive data on a non-encrypted SSD then a good way to physically decommission the drive is to heat it with a propane torch until the PCB catches fire. At that point the magnetic domains aren't magnetic anymore. -- Willy Yam [This question got some great answers, and in addition provided some interesting insight into the differences between traditional hard drives and SSDs, and why SSDs are harder to rid of data.

NOTHING=GOOD CRM...SEARCH FOR NOTHING ON A REGULAR BASIS!

Speaking of nothing...

With oodles of details about your customers in a given "digital phone book" or CRM (customer relationship management) software, it is really nice to get reports of all the details that you have stored.



Almost as important is to report on what is missing. "Looking for nothing" can accomplish any of the following important questions:

• Which customers are missing a postal code / zip code before we send out our mass mailers (you can read that as "ma$$ mailer$" when the bill arrives)?
  
• What city is the most popular office location for our customers? Is the city spelled correctly so that I can get the proper numbers (e.g. Calgary, calgary, Cal gary)?
  
• Who is missing a job title? How accurate is the spelling of the job title, and how current are the job titles on-file?

I'm sure you can predict the embarrassment that might arise if your office forgets to "search for nothing" just prior to a mass communication, eh?
