| Jun 18, 2021 at 5:03 | comment | added | Doc Brown | @Christophe: when you and me were young., Google did not even exist, and resources for this topic were sparse and much harder to find ;-) My comment above was honest: I wanted to know if the OP had anything done to prevent reinventing the wheel, so it could be used to improve the question (and the fact they ignored me isn't really motivating me to reopen the question). But alas, in the light of your answer and your last edit to the question, I will vote to reopen, either. | |
| Jun 17, 2021 at 23:05 | comment | added | Christophe | @DocBrown to OP's defense: when I was young, I really believed that writing once a set of 0 was sufficient to shred drives before throwing them away. I knew that some tools wrote several passes of random data but I thought this was pure marketing and loss of time. It's only later in specialized seminars that I discovered about existence of some advanced recovery techniques i could not have googled for because I never ever heard the terms (remanence was only the most striking one). OP did more than googling: he/she wrote & tested code; Doesn't his/her engineering prudence deserve answers? | |

| Jun 17, 2021 at 22:49 | comment | added | Christophe | @marstato although the initial wording of the question could give the impression of poor research, in all objectivity, OP has made research on basic deletion mechanisms by OS, and has experimentally tried and tested a strategy which seems to work. In particular OP wants to know that if he/she verifies erasure and reads a NULL byte, if there are not means to read the original data. This suggests that OP has also found out that others write something else than NULL, and demonstrates in any case a high sense for producing reliable software. I therefore vote fore reopen the question. | |

| Jun 17, 2021 at 14:22 | comment | added | gnasher729 | We all haven't ever heard of "recycling a file". What you have seems very dependent on the operating system. If I want to erase a hard drive, I use Disk Utility. And my hard drives are always encrypted, and Disk Utility will just erase the encryption keys. Everything is still there, but nobody can ever read it. | |

| Jun 17, 2021 at 13:01 | comment | added | Doc Brown | Which search terms did you use at Google to find out about competing programs (so you can lookup how they do it)? | |
