IMO, it's ok for disk devices to develop unreadable blocks (bad blocks),
No it's not ok. Unreadable blocks means lost data.
Internal firmware of the disk takes care of bad blocks, marks them
internally and reallocates them. (makes sure that next read\write
request to that bad block will be redirected to a safe block)
The next *successful* read/write.
At least this is how things should work. But in my experience, bad
blocks are not reallocated so easily.
