How do you permanently erase data so that it cannot be recovered?

To permanently erase data, use software to overwrite it (like Eraser, DBAN for drives, or file shredders) by writing random data multiple times, or for ultimate security, physically destroy the drive (shredding for SSDs, degaussing for HDDs), as simple deletion leaves data recoverable; for phones, use a secure erase feature or software.

How to permanently delete files so they cannot be recovered?

To ensure deleted files are unrecoverable, you must overwrite the data using file shredding software (like Eraser or BleachBit) or built-in tools (Cipher /w on Windows for free space), which physically overwrite the sectors where the file once resided with random data, making it nearly impossible to restore; for ultimate security, especially with SSDs, physical destruction or cryptographic erasure (full disk encryption + key deletion) is best.

A deleted file doesn't really disappear from your hard drive; it stays there until new data fills up the space it occupied. This process might be hard to understand for people who don't know much about how computers handle files.

Will submerging a hard drive in water destroy it?

Yes, water will damage a hard drive, potentially destroying its functionality by shorting electronics and causing corrosion, but it typically won't erase the magnetic data on the platters, meaning data recovery is often possible unless contaminants (like salt or dirt) are left to dry and damage the platters, making physical destruction (shredding, degaussing) necessary for secure data wiping.
 

How to 100% wipe a hard drive?

To 100% wipe a hard drive, use a secure erase tool like DBAN for a complete overwrite, the built-in "Remove everything & Clean the drive" option in Windows Settings (for Windows 10/11), or your drive manufacturer's SSD utility for SSD Secure Erase; for extreme sensitivity, physical destruction is best, but software methods like DBAN or Windows' built-in reset with the clean data option are effective for most users before selling or discarding. Always back up your data first, as wiping is irreversible.

Does a factory reset really delete everything?

Yes, a factory reset deletes virtually all user data and settings, returning a device to its original "out-of-box" state, including apps, photos, messages, and accounts, but it doesn't delete the core operating system or data in cloud backups unless you specifically choose to. It's crucial to back up everything important first, as the data is permanently removed from the device's local storage, though modern encryption makes recovery very difficult, according to.

That's why it's often possible to retrieve deleted files using data recovery tools. However, success depends on how quickly you act and whether new data has overwritten the original file.

Can permanently deleted things be recovered?

Can a magnet wipe a hard drive?

In theory, a magnet could be used to corrupt data on a hard drive. However, your average magnet, or even a relatively strong one, would not be strong enough to have any effect on a hard drive. You would need to bring an extremely powerful magnet into contact with the magnetic platters of a hard drive.
