- is this disk really "degrade" or not?
Disks aren't in degraded mode. The RAID system will run in degraded mode when the disk eventually fails.
- how O.S. can predicate disk going to failure?
The disk's SMART feature tells it so.
- do I need replace this disk now?
That would be a good idea, the disk could fail in 5 minutes or in 5 month, you can't tell.
