Abstract
A method of erasing data from a data storage apparatus comprising a memory, the method comprises writing a known data pattern to a plurality of known memory locations of the data storage apparatus, causing the data storage apparatus to perform a data erasure procedure, reading data stored at the known memory locations after completion of the data erasure procedure, comparing the read data and the data of the known data pattern, and determining a verification result based at least in part on the result of the comparison between the read data and the data of the known data pattern.
Claims26
A method of erasing data from a data storage apparatus comprising a memory, the method comprising:
- writing a known data pattern to a plurality of known memory locations of the data storage apparatus;
- causing the data storage apparatus to perform a data erasure procedure;
- reading data stored at the known memory locations after completion of the data erasure procedure;
- comparing the read data and the data of the known data pattern;
- and
- determining a verification result based at least in part on the result of the comparison between the read data and the data of the known data pattern.

(canceled)
A data eraser apparatus configured to:
- write a known data pattern across a plurality of known memory locations of a data storage apparatus;
- perform, or cause the data storage apparatus to perform, a data erasure procedure;
- read data stored at the known memory locations after completion of the data erasure procedure;
- compare the read data and the data of the known data pattern;
- and
- determine a verification result based at least in part on the result of the comparison between the read data and the data of the known data pattern.
A computer program product comprising computer-executable instructions that are executable to:
- write a known data pattern across a plurality of known memory locations of a data storage apparatus;
- perform a data erasure procedure at the data storage apparatus;
- read data stored at each of the known memory locations after completion of the data erasure procedure;
- compare the read data and the data of the known data pattern;
- and
- determine a verification result based at least in part on the result of the comparison between the read data and the data of the known data pattern.
