Abstract

Method and apparatus for purging information from a storage medium such as a floppy disk or a hard disk drive. A region to be purged is defined such as a storage medium or a portion of a storage medium. A purge is performed of the defined purge region by overwriting all locations in the defined purge area with a character, the complement of the character, and a random character. A number of wipe iterations may be defined where the performing is repeating until the defined number of wipe iterations is attained. The purge may also be verified by reading all locations in the purge region, and checking for inconsistent data and remaining original data by comparing all read locations with the last character written during the purge.

Claims

1. A method for purging information from a storage medium comprising:

defining a region to be purged, the region comprising one of a storage medium and a portion of a storage medium; and

performing a purge of the defined purge region by overwriting all locations in the defined purge area with a character, the complement of the character, and a random character.

2. The method according to claim 1, further comprising defining a number of wipe iterations, the performing repeating until the defined number of wipe iterations is attained.

3. The method according to claim 1, wherein the storage medium comprises one of a floppy disk and a hard disk drive.

4. The method according to claim 1, wherein the portion of a storage medium comprises one of at least one partition of the storage medium and at least one sector of the storage medium.

5. The method according to claim 1, wherein the character comprises one of a ‘

1’ and

a ‘

0’

.

6. The method according to claim 1, further comprising generating the random character by extracting bits from the number of system clock ticks over a period of time.

7. The method according to claim 1, further comprising generating the random character using the date and time.

8. The method according to claim 1, further comprising verifying the purge.

9. The method according to claim 8, wherein the verifying comprises:

reading all locations in the purge region; and

checking for inconsistent data and remaining original data by comparing all read locations with the last character written during the purge.

10. The method according to claim 8, further comprising generating a message that the purge region is not fully sanitized if the purge does not verify.

11. An article comprising a storage medium with instructions stored therein, the instructions when executed causing a computing device to perform:

receiving a definition of a region to be purged, the region comprising one of a storage medium and a portion of a storage medium; and

performing a purge of the defined purge region by overwriting all locations in the defined purge area with a character, the complement of the character, and a random character.

12. The apparatus according to claim 11, further comprising receiving a number of wipe iterations, the performing repeating until the defined number of wipe iterations is attained.

13. The apparatus according to claim 11, wherein the character comprises one of a ‘

1’ and

a ‘

0’

.

14. The apparatus according to claim 11, further comprising generating the random character by extracting bits from the number of system clock ticks over a period of time.

15. The apparatus according to claim 13, further comprising generating the random character using the date and time.

16. The apparatus according to claim 11, further comprising verifying the purge.

17. The apparatus according to claim 16, wherein the verifying comprises:

reading all locations in the purge region; and

checking for inconsistent data and remaining original data by comparing all read locations with the last character written during the purge.

19. The method according to claim 18, wherein the executable file comprises a script file.

20. The method according to claim 18, further comprising initiating the purge remotely from the computing system.

18. A method for removal of information from a computing system comprising:

selecting at least one information removal option;

generating an executable file based on the selection; and

purging information from at least one computing system by execution of the executable file.
