WRITE and VERIFY Command
This command is similar to the traditional "read after write"
function.
It is an extended address command which operates like
a WRITE command over the specified number of blocks and then
verifies the data written on a block by block basis. The verify
function transfers no data to the host and only checks the ECC to
be correct.
Since no data
is
transferred
to the host during verify,
correctable data checks will be treated in the same manner as
uncorrectable data checks.
Valid Error:
500504-00
