Does factory reset actually erase everything?
A factory reset erases most user data (apps, photos, settings) and returns a device to its original state, making data seem gone, but on older systems, data might be recoverable with specialized tools because it just marks data as "free". Modern devices with encryption (Android, iOS) offer better security; a reset wipes encryption keys, making data largely unreadable, but a full, secure wipe requires encryption before resetting or overwriting data with junk to truly scramble it for maximum privacy, especially before selling.Does a factory reset really delete everything?
Yes, a factory reset deletes almost everything user-related (apps, photos, settings, data) to return a device to its original state, but it doesn't always securely wipe data for forensic recovery unless encryption is involved or an extra secure-erase step is performed. Modern devices with default encryption (like iOS/Android) make old data unreadable after a reset, but for absolute certainty before selling, you might need to use specific "secure erase" tools or fill the drive with junk data first.Can police recover data after factory reset?

A factory reset erases most user data (apps, settings, photos, etc.) and returns a device to its original state, but for highly sensitive data, it might not be permanently unrecoverable without extra steps like encryption or secure wiping tools, as data remnants or encrypted data might linger, though modern encryption makes it tough for casual recovery, say Reddit users. For most users selling a device, a reset is enough, but for extreme security, encrypting first or using specialized software that overwrites data is best.Can a person who bought my phone recover my data after a factory reset?
A person who buys your phone probably can't recover detailed personal data after a modern factory reset due to strong encryption and secure erasure, especially if you removed your accounts first; however, extremely determined individuals (like government agencies) with specialized tools might find remnants, but for the average buyer, your data is safe, as the reset essentially deletes the keys to encrypted files. For maximum security, always remove accounts, encrypt the device before resetting, and maybe use a secure erase app or fill the storage before wiping again.How to Secure Erase Data on Android Phone

Yes, water will damage a hard drive, potentially making it unusable by shorting electronics, corroding components, or causing read/write head crashes, but it doesn't necessarily destroy the data itself; data can often be recovered by experts, as it's stored magnetically on platters inside a semi-sealed chamber, though prolonged exposure or drying contaminants can make recovery difficult. For secure data destruction, water isn't enough; physical destruction (shredding) or wiping software is needed.How do I verify that my hard drive is fully wiped?
