C. A drive wipe utility can truly overwrite data. A “Department of Defense” wipe will perform this overwrite operation at least seven times to truly obliterate the data on the drive, making it unrecoverable.
Not A. Degauss – Can’t reuse the disk. The magnetic erasure rearranges the magnetic field to such an extent that standard read heads are unable to find a magnetic reference point for tracking.
Not D – users aren’t able to do a true “low-level” format. That’s something done at the factory.
Not B – Standard/Full/Regular formatting are differnet names for the same thing – each sector is checked for errors and overwritten with with zeroes. But there are special utility programs that can recover data from drives that have been overwritten once or twice by zeroes.
