Abstract
Embodiments provide unique and novel systems and methods for deleting data on removable drives. In embodiments, the removable drives store data that may be erased such that the data is considered destroyed but that allows the removable drive to be reused. The archiving system can determine which data should be erased. Then, the data is digitally shredded on sector boundaries of the removable drives such that the reclaimed memory cannot be read to decipher the erased data. In alternative embodiments, data is written across sector boundaries such that two or more files may occupy a single sector. A journal area allows for copying the data in a sector with two or more files, digitally shredding the sectors in the removable drive, and rewriting the data that was not to be digitally shredded to the original location of the data.
