How do you permanently erase data so that it cannot be recovered?
To permanently erase data, use data wiping software like Eraser or DBAN to overwrite drives with random data (e.g., DoD 5220.22-M standard), or for physical destruction of SSDs, physically pulverize the NAND chips; for general file deletion, use file shredders after emptying the Recycle Bin to wipe free space, but for complete assurance on HDDs, full drive wiping or physical destruction (drilling/shredding) are best.How to permanently delete files so they cannot be recovered?
To ensure deleted files are unrecoverable, use a file shredder program like Eraser or BitWiper to overwrite data, or use built-in tools like Windows' cipher /w to wipe free space, but for absolute certainty on HDDs, physical destruction is best, while SSDs benefit from their built-in Secure Erase feature, as data overwriting on SSDs isn't always reliable due to wear leveling.How to make data non-recoverable?
Destroying media can also prevent data recovery.- Degaussing – High-powered magnets are passed over the hard drive, demagnetizing the platters and destroying the data. ...
- Shredding – Commercial shredders can demolish hard drives, SSDs, data tapes, and other media. ...

How do you completely wipe a hard drive so no data can be recovered?

That's sufficient to make the original data unrecoverable by even the most advanced forensic laboratories.Will submerging a hard drive in water destroy it?
Yes, water can destroy a hard drive's functionality by shorting electronics and corroding components, but it often won't destroy the data because the platters are in a sealed chamber; data recovery is usually possible, though expert help is needed, as water introduces contaminants that can damage the platters and heads if not handled correctly.How To Permanently Delete Files So They Can't Be Recovered | Completely Erase Data From Phone & PC
How to 100% wipe a hard drive?
To 100% wipe a hard drive, use a secure erase method like writing zeros over the entire drive, best achieved with specialized software like DBAN (Darik's Boot and Nuke) for total data destruction or Windows' built-in "Remove files and clean the drive" option (for HDDs) to make data unrecoverable, though it takes time. For SSDs, secure erase features are often built-in or available through third-party tools, as simple overwriting isn't as effective due to over-provisioning.Can police recover data after factory reset?
Yes, police can often recover data from a factory-reset phone, especially older models, using forensic tools, but it becomes much harder, though not impossible, on newer phones with strong encryption (like Android 9+ FBE) because the encryption keys are deleted, scrambling the data. While a factory reset removes most user-facing data, forensic specialists can sometimes access remnants or unallocated space, but truly wiping modern, encrypted phones requires physically destroying the memory chips.Are permanently deleted files really gone?
