The latter command typically fails because the SAT layer of the
controller driver or firmware does not properly return ATA output
registers in SCSI sense data. Smartctl prints "SMART WRITE LOG does not
return COUNT and LBA_LOW register" in this case.
For further diagnostics, please provide output of:
smartctl -r ioctl,2 -d sat+megaraid,$id -l scterc /dev/sda"
