If a block goes bad in a partition, does that permanently reduce the

compensate?
Modern disk drives and SSDs usually have extra blocks that are used to
re-map bad blocks as they are detected. As long as there are still
blocks to perform the re-mapping you don't lose space. Once those
blocks are consumed I believe there are ways to manually tell the file
system that there are bad blocks and yes, that would then permanently
reduce the space.
FWIW I have never had to deal with any of the above. In my experience
spinning drives fail before bad blocks become an issue.
That's good news.
Thank-you.
