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"
