I have experimented on Disk Drives before in this room. And to say it is a 98% chance to brake things is just wrong. I have tow drives who have been completely overwritten several times - after opening them! 256GB & 512GB There is in most HDDs a mechanism to catch dust particles before they become a danger! It is not that I have important Data on does Drives, but they are o.k. And is it wrong to say you open a HDD in an „non clean room“ and it instantly kills the drive! Even if this ceiling here has drooped some dust on it, most likely it will do nothing! I just would like to know why there would be high chance to fix this drive, when there are already some trails on the disk. How could this be? And when I would want try, what should I do?
