Hello,
Do you know if there is a hard disk firmware repository, or more simply or a dump tools ?
In addition to being able to switch firmware with the most advantageous programming (number/duration of head parking for example)
that can influence the life span…
The idea is of course to be able to compare and check the integrity of firmware because, as you know even the firmware of a hard disk can be a backdoor
