Where to find secure hard data drive destruction
I am closing up shop at the end of the month and have much information in regard to customer profiles and payments that need to be disposed of completely.
I do not want to run the risk of my computers being hacked into and the identity or credit card information taken so where do I find secure hard data drive destruction?
I have read of services such as smelting and shredding but am not sure where to begin looking locally for a company who offers these services.
Also, how do I know that they have actually done this and to the degree that the information is completely gone?
