Do the DEP approved electronics recyclers ensure data security?
Yes. Under the state recycling program, approved recyclers are required to establish data security practices. They must secure hard drives until such point they are physically destroyed for recycling such as by shredding or smelting. If they intend to reuse or resell the computer, they must erase the hard drive to a Department of Defense standard. If you wish to recycle your computer but are concerned about data security, either erase the data yourself or ask the recycler about their procedures for erasing.
