FYI on data security: 

Other companies prey on your fears about data security by charging you money to damage the environment.   They promise to completely destroy every part of the computer, resulting in unnecessary creation of waste products.   But that ignores the reality about how and where data is stored on your computer!

The How and Where of Data Storage: 

Data is only stored on your drives.  That's why when your hard drive fails, you loose data.  Your recycle bin and recovered files are all stored on your hard drive.  If you store data on a server, it's on one of the server's drives.  Other storage methods, such as floppy, CD-ROM, and tape drives, use removable media, which you've likely stored away just in case your hard drive died.  Why pay a company to landfill the rest of the your computer when only the drives can contain data?

Data Destruction: 

Any removable media found in your system, such as floppy disk, CD-ROM's, and data tapes, will be destroyed, unless you remove them first.  There are 2 options for hard drive data destruction, the first is to erase your data and rewrite the data area with junk, the second is to destroy the drive completely.

Erasure versus Destruction: 

You may have heard that erased drives can sometimes be recovered.  To prevent this, we rewrite them with junk data.  That insures that any attempt to recover data from the drives will recover only the junk data that we wrote to the drive.  Rewriting the drive is so effective, the Department Of Defense has used this method for years!  But if you're still paranoid, we also offer additional service to physically destroy the drive!

How erasure works: 

Drives store data as a series of 1's and 0's.  These 1's and 0's are stored using magnetic particles which can be charged either positive or negative.  When we overwrite the entire drive, we change the polarity of those particles in a pattern inconsistent with the original data, hence, any attempt to recover data recovers only the junk from when the drive was overwritten.

How destruction works: 

We physically remove and destroy the data platters of any drive scheduled for destruction.  We can return the platters to you at your request..  There is a small fee for the labor involved, which is outlined on the Services page.
