DATA DISPOSAL AND DISPOSAL FACTS EXAM
QUESTIONS WITH 100% RATED ANSWERS, GET A+
What should you always do before disposing of a computer? - Always format the hard drive
before disposing of a computer. This helps prevent unauthorized access to previously stored data.
What is a high-level format? - A high-level format is performed using operating system tools and
removes pointers to files, making data harder to access. However, the data itself remains on the
drive and can be recovered with special software.
What additional action does a high-level format perform? - A high-level format also writes a file
system such as NTFS to the drive. This allows the operating system to organize and store new
data.
Can data be recovered after a high-level format? - Yes, because the actual data is not erased, only
its references are removed. Specialized software can often recover this data unless it is
overwritten by new data.
What is a low-level format? - A low-level format recreates the sectors and tracks on the drive
and fills all empty space with zeroes. It is typically done by the drive manufacturer during
production.
Is a low-level format typically performed by users? - No, a low-level format requires special
tools and is not recommended after the manufacturer has performed it. Performing it improperly
can damage the drive.
What does a low-level format physically do to a hard drive? - It writes new sectors and tracks
onto the surface of the drive. It also erases all existing data by overwriting it with zeroes.
Why is physical destruction of a hard drive used? - Physical destruction ensures that no data can
be recovered from the hard drive. This is the most secure method of data disposal.
What is a disk shredder and what does it do? - A disk shredder is a specialized machine that cuts
a hard drive into tiny pieces. This method is very effective but expensive.
