the HDD that I want to sell has sensitive data.
the plan is (was) to do a "quick format". and delete partitions if any.
but I read formatting a drive doesn't REALLY erase data, only erases file allocation information and data can still be restored with certain applications.
so what DOES erase data in such a way I can be rest assure the sensitive data is lost forever and can't be restored ? is it called "drive wiping/scrubbing" (like I have in my "CCleaner" application) ? if so how many overwrites (passes) is recommended in my case?
bear in mind, I need to sell this HDD so I don't it to be damaged in any way.
