Refer to the information below to answer the question. Desktop computers in an organization were sanitized for re-use in an equivalent security environment. The data was destroyed in accordance with o

Knurling is a machining process used to create a textured surface pattern on metal for grip purposes and is not a recognized data destruction or media sanitization method.

Grinding can be used for physical media destruction but is typically applied to hard disk platters; for small PDA solid-state flash memory chips, shredding provides more consistent and complete destruction of all components.

Shredding physically destroys the storage media of a PDA into small fragments, making data recovery virtually impossible regardless of device functionality. This is especially critical for malfunctioning PDAs where software-based wiping cannot be performed, as shredding eliminates the physical substrate on which data resides. It is a widely accepted NIST SP 800-88 compliant destruction method applicable to solid-state and flash-based media found in PDAs.

Degaussing is effective for magnetic media such as traditional hard drives and tapes, but PDAs use solid-state flash memory which is not affected by magnetic fields, making degaussing ineffective for PDA data destruction.
