No Data Trace Left Behind
As you are probably aware, you can erase any file from a hard drive with just the click of a mouse. However, seeing it gone does not mean that it is gone. This “delete” function often leaves traces or even full versions of the data that can be recovered in various ways.
To render data irretrievable, the drive must be securely wiped or erased. Wiping a drive usually involves actually adding new data to the drive that replaces any encoded information with only zeroes or ones. This is because all digital data is based on binary code, which is comprised of a series of zeros and ones.
The Data Sanitization Process
The Department of Defense’s data destruction guidelines as outlined in DOD 5220.22-M, clarify secure data wiping as ‘the overwriting of each sector of the disk no less than three times.’ The manner in which the process occurs is as follows:
- On the first pass, all of the data in each sector is replaced by a character
- On the second pass, each character is replaced by its complement
- On the third pass, each sector is then filled with a random character
Some believe that deleting files means that sensitive data is secure, but this video explains why a more thorough sanitization process is needed:
Every Device Holding Data Gets Erased at TechnoCycle
All data-bearing devices entering our facilities are securely wiped to this standard and any hard drives failing this process are destroyed, so you can rest assured that your sensitive data is protected.
TechnoCycle purges all data from your hard drives. Once the sanitization is completed, we issue a Certificate of Purging which includes the serial number of the hard drive, the date it was sanitized and confirmation that it was done in accordance with the NIST 800-88 standards and DOD 5220.22-M standards.
