No, formatting just re-create the file system for a drive for using. Recoverable data contents or details are still there, available for both new data to overwrite them and recovery software to get them back.
Are you talking about deletion instead of formation, because what you said is what happens to delete
No, Delete is to delete the reference or the header of a file, not the content. Format, however is safer than delete and harder to get data back, but still, Format is not secure enough to protect data.
What should I do, format or wipe?
Depends on how will you deal with the hard drive.
Which situation suits you?
- Reinstall or upgrade to new system
- Return company’s laptop to IT dept
- Donate / give it to others you don’t know
As of self-using again, format is enough to make the disk empty, not clean. And formation takes less time than wiping, if there’s no sensitive data on the disk or anywhere of the partitions, go Format.
Once the computer, laptop or the hard drive is not at your hand, wipe everything out is safer to protect personal private.
