Every company regardless of nature and size has some sensitive information or data that it would rather keep to itself. Some businesses are more sensitive than others are. The best way to make sure data never leaks out is to destroy it completely once you no longer have use for it. You can also look for law enforcement data destruction services via CJIS Shred.

Types of Data Destruction:
Overwriting: Data is overwritten with 1s or 0s in one or several passes to make it perfectly unrecoverable. A recommended approach if you want to get rid of data in a cheap yet effective method.
Degaussing: The disk is exposed to an unusually strong magnet that can erase the entire contents of the disk, regardless of its size, in just a few seconds. Perfect for quick data destruction but be wary if your disk has servo tracks because a degaussed servo track will render the disk inoperable.
Physical Destruction: Using this approach, you are to destroy a hard disk drive intentionally so that it is no longer operable; therefore, data can no longer be read or recovered. A permanent solution if you want the data to be gone for good or to dispose of a hard disk drive safely. You can do the destruction yourself but for a faster and more professional approach, send the disks at hard drive destruction services.
The choice of data destruction depends on the following factors: type of hardware, impact/risk level, number of items required in data destruction, and cost you will have to put up to get it destroyed. Remember that the sooner you start, the cheaper and more effective data destruction will be.
