jaclaz, firstly, thanks for your attention.
I've been reading the topic and some of it's many pages carefully. It's a lot more comfortable to try it knowing that the risk of permanent loss is not significant.
The fact that the "fix" is a nonspecific sort of "generic" attempt to help with the BSY error gives me a lot more hope because I think there's the possibility to
work with different firmwares versions.
Do you think the power on/off step is it really necessary? This specific step let me a bit concerned. Is it possibile to skip it and proceed normally?
Do you know what is the intent behind this step? Did you have the opportunity to test the method and it's particularities in some hd's?
I totally agree with you. Some deep analysis could only be possible with some some profound knowledge. So, could be acceptable to take some
minimal risks if the chances are good, but I'm still considering, trying to do research and reading a lot.
Professional recovery methods are too much expensive, so there aren't many options to me.
Maybe next time I should invest in some backup solutions just to prevent these situations.
