Format, delete or wipe a hard drive before selling/donating, which is better?

Did you guys hear the horror stories that someone buys a second-hand hard disk from eBay or the flea market, and then find lots of personal data still on the drive left by the previous user? Or what’s worse, if it is the cyber criminals that got such used hard drive, then there are chances that they will take advantage of the privacy information to threat and blackmail the previous owner.

It would never happen to me, since I will delete all partitionson the disk, or format the drive when I don’t need it any longer, all the data is absolutely cleared” you might say. Sorry to tell that all the data you believed erased actually still exists on the hard drive. The data just becomes invisible, but not gone forever.

What you should do is to completely wipe the hard drive to clear the data permanently, which is much better and safer than only deleting or formatting it before selling it or giving it to others. So you might need a professional hard drive eraser.
