one point, when a bad block gets remapped, you do (stand a very good chance that you) loose the data on that block.
the problem with having the OS do bad-block mapping is that people use drives with different OS's, and they would all have to know about all the bad blocks, what they were remapped to, etc.
drives used to work this way, the reliability of having the OS do this (even in cases where you weren't dual-booting) was bad enough that at the time it migrated into the drives so that the OS could forget about this, everyone considered this a step forward.
it's far more complicated for the drive to do the remapping than to let the OS do it, so it wasn't just a whim that change things so that every drive manufactured does it internally.
