Description

ATA ACS-4 introduced three new function codes for SCT Error Recovery Control command:

0001h Set Current Timer Value (ATA-8 ACS)
0002h Return Current Timer Value (ATA-8 ACS)
0003h Set Power-on Timer Value (ACS-4)
0004h Return Power-on Timer Value (ACS-4)
0005h Restore Manufacturer’s Default Timer Value (ACS-4)

See Table 201 of T13/BSR INCITS 529 (ACS-4) Revision 20 (October 2017).

smartctl -l scterc,... should be enhanced (or replaced by new --get/set commands) to support these settings.

Unfortunately ACS-4 does not specify a way to check whether this enhancement is supported. Drives returning new Minimum supported value for the RECOVERY TIME LIMIT field in SCT Status Response may also support this enhancement.
