22 Common Regarding the correction copy or the drive copy, in
case ECCs/LRC PINs are set on the track of copy
source HDD, mode 22 can be used to interrupt the
copy processing (default) or to create ECCs/LRC
PINs on the track of copy target HDD to continue
the processing.
Mode 22 = ON:
If ECCs/LRC PINs (up to 16) have been set on the
track of copy source HDD, ECCs/LRC PINs (up to
16) will be created on the track of copy target HDD
so that the copy processing will continue.
If 17 or more ECCs/LRC PINs are created, the
corresponding copy processing will be interrupted.
Mode 22 = OFF (default)
If ECCs/LRC PINs have been set on the track of copy
source HDD, the copy processing will be
interrupted. (first recover ECCs/LRC PINs by using
the PIN recovery flow, and then perform the
correction copy or the drive copy again)
