Disks aren't in degraded mode. The RAID system
will run in degraded mode when the disk eventually
fails.
2. how O.S. can predicate disk going to failure?
The disk's SMART feature tells it so.

2. how O.S. can predicate disk going to failure?
As I understand it, disks can handle a certain amount of bad 'sectors', thanks
to some hidden extra space.
When a 'sector' fails, the disk marks it as 'bad' and then map it to a 'sector'
from the hidden

That would be a good idea, the disk could fail in
5 minutes or in 5 month, you can't tell.
Or, indeed, 5 years. I have a number of throwaway workstations at
one customer site -- throwaway in

Depends on your point of view, to me it would be. I remember
two situations with predictive failure on HP Smart arrays a
few years ago where the drives were practically dead but the
controller kept using them dragging performance down
