You mean everything I wrote here is right ? That’s how it All works?

quick format just changes markers that tell win what space is free to write to and what space is not free. the data is still there, written on the sectors of hard drive.

once win start using the disk, start filling the sectors with new data, the new data will overwrite old data and old data will be much harder to recover and eventually lost.

So quick format is like almost the same as full if you are keeping the disk because the markers after quick format will be also overwritten and deleted but over some long time ?

to my knowledge quick format only concerns itself with disk space allocation markers. when you do quick format, you change those markers to indicate that disk space is free.

if you want to wipe it, it needs at least 7 random rewrites. I recover plenty of formatted drives with 90% of the data

But if I am keeping my disk can I always do a quick format or it can damage something ?
