PS The Parameters Savable bit of 1 indicates this

parameter page is savable in non-volatile RAM.

enables the automatic reallocation of defective sectors

during the write operation of the Write commands

(0AH, 2AH, AAH), Write and Verify commands (2EH,

sectors occurs during these additional erase operations:

reallocation of defective sectors.

is not recovered within the recovery limits specified is

transferred to the initiator before CHECK CONDITION

transferred to the initiator.
