Message A BBR entry added for mapping sector x to sector y on HDDz
Description
An entry of bad block reallocation table at was allocated for

Event ID 0x1408
Type DISK Severity WARNING Parameters
Sector NO,
Disk ID
Message Invalidate sector x on HDDy
Description
The controller marks an area starting from sector x on hddy as
non-trustable by recording the sector in the bad block realloca-
tion table. When the controller accesses the invalidated areas, it
returns media error to hosts. This happens when the controller
cannot rebuild data from remaining disks (This results in data loss),
but the area on disk is still accessible. The mark could be
removed when hosts writes to this area or corresponding logical
disk is re-created.
Advice
If the number of BBR table entries being allocated grows excep-
tionally fast or beyond a reasonable number, consider to con-
duct diagnostics and replace with new disks.

Message Read from an invalidated block at sector x on HDDy
Description
The hosts read data from sector x on hddy which was previously
marked an invalidated area. The hosts got media error from the
controller. This happens when the controller cannot rebuild data
from remaining disks (This results in data loss), but the area on disk
is still accessible.
Advice
If the number of BBR table entries being allocated grows excep-
tionally fast or beyond a reasonable number, consider to con-
duct diagnostics and replace with new disks.
