Thank you for response,
Well, thats sad they also locked terminal, without working SMART or at least some way to check G-list and head resistance, the disk is somewhere between "one damaged SA sector" and "total wreck minutes before death"
Seems like there is nothing else to do, just to trash it. It is also funny that some MBs can access and read data on the drive and some cant. I have no idea how some BIOSes can totally freeze and some work fine while using the same read commands.
Also, about the system drive, It was my testing computer I quickly put together. I used some random old HDD with few reallocated and pending sectors, but actually the disk suddenly died yesterday. I replaced it with another old HDD with half capacity but OK status, so no big deal
