Refurbishers are the companies that put computer systems on lease and when the lease is finished, they are being returned and are re-sold at a reduced price or donated to charity. Corporations buy refurbished computers and hardware for numerous reasons. Returning the computer to a refurbisher includes completes data erasure of the previous company as it contains sensitive data. As the data is highly sensitive, it may happen that data erasure has possibly not been performed completely and the computer system might fall in the prying eyes. The wrong hands can thus misuse the data.
BitRaser introduced an effort to completely erase the data off the hard drives and combat data leakage.
