Those tools are for fixing software related causes. You’re problem is hardware related. Which recovery tool did you use, because you need to use one that is capable of recovering data from a RAW drive. There aren’t any I can specifically recommend (a google search for “recovery tool RAW archive type”, should get you started). I’d suggest you tried a number of tools, and go from there.

and about the program you’re offering here, is it free or it is cracked?
because if you recommend me to use it, i will

i’ve tried to do the recovery a while ago, but it doesn’t allow me to do it for some reasons that after leaves the error mentioned on this blog, and i’m trying to check the external disk from properties from my pc program

Your only solution is to recover the data on the external device using a recovery tool, then format the drive after. There are a number of these tools around, so I suggest you look for one of them. If the drive is completely inaccessible, then a format may or may not give you access to drive. The situation depends on the extent of damage, whether the sectors are physically damaged or the data on them is just corrupt. But, go with the recovery first.
