Figure 119. WRITE A N D VERIFY (2E)
WRITE AND VERIFY command requests that the file writes the data transferred from the initiator to the
medium and then verify that the data is correctly written.
Transfer Length of zero indicates that no data is transferred.
If caching is enabled, the command performs an implied Force Unit Access (FUA) and an implied Syn-
chronize Cache before starting the operation. This insures that the medium, not the cache, is being veri-
fied.
ByteChk is not supported. Must be set to zero.
DPO (Disable Page Out) is not supported, however, D P O bit set to 1 is not rejected and ignored inter-
nally.
Relative Block Address is not supported. Must be set to zero.
