I believe the N/A setting for bit 4 is correct. This means that a
drive is free to set this bit or not... Since some hosts still check for
50h as opposed to bit 7=0 and bit 6=1 we still set bit 4 for many commands.
In ATA8-ACS, the SCT clause uses the smart commands and to the best of my
knowledge does not modify the status bits at all.

Subject: [t13] SCT using old SKC status bit?
This message is from the T13 list server.
It seems that some of the SCT documents want the SCT commands ([SMART] R/W
LOG [EXT]) to use Status bit 4 (the old SKC bit) - I see that these
commands should end with status of 50H or 51H. This seems to disagree with
the ATA-8 ACS normal and error status tables for the SMART and R/W LOG
[EXT] commands where Status bit 4 (that old SKC bit) is defined as N/A.
Isn't the more correct ending status for an SCT command either 40H or 41H?
