Why each option
To securely remove PII from hard drives intended for repurposing, degaussing is the most effective method among the options provided as it uses a strong magnetic field to completely erase data, rendering it unreadable.
Drilling physically destroys the drive, preventing repurposing.
Degaussing uses a powerful magnetic field to disrupt and randomize the magnetic domains on a hard drive's platter, effectively rendering all data unreadable and unrecoverable. This method is highly effective for securely erasing data from magnetic media like HDDs before repurposing.
Low-level formatting typically involves re-creating the track and sector markings on a disk, which does not securely erase data, as data recovery may still be possible.
Incinerating physically destroys the drive, preventing repurposing.
