While built-in tools are convenient, third-party software usually offers higher security. Consider your specific security needs before deciding.

Q3: How long does the wiping process take?

The duration varies based on factors like hard drive size and chosen wiping method. Quick formats are faster than full formats.

Q4: Can wiped data be recovered?
