"but shouldn't we perhaps leave it up to the end user / owner of the
hardware, to decide when it's ready for the recycle bin ?"
with hard drives (forget SSDs, they are hardware accelerators absolutely
unaffordable for data storing) it is not the user/owner that decide it , unless
he doesn't
P.S. needless to be said, that they eventually can reassemble damaged LVM ,
until LVM's metadata tables are still good enough

Zdenek is right
But if in this exact moment one or more drive do have not only bad sectors
"reallocated" but also "pending" ones
the best choice is to preserve them shutting them off and allowing a PRO
cloning process with machines like PC-3000
But first at a PRO lab, they will open the

so tell me then, why i have a shelf full with dead disks where half of
them are out of business for nothing but a couple of bad sectors ?

1977 called, they'd like their non-self-correcting HD controller
implementations back.

I use a utility that maps bad sectors to files, then move/rename the
files into a bad blocks folder. (Yes, this doesn't work when critical
areas are affected.) If you simply remove the files, then
modern disks will internally remap the sectors when they are written
again - but the quality of

by reducing off of the end and making it smaller.
yes, that's clear to me.
