The HL-DT-ST GCC 4244N is a slimline DVD drive. On my laptop it replaced a TEAC CD-224E. Both of these drives use a JAE KX15-50KLD 50 pin connector, which does not have jumper pins. It appears that the host determines whether the drive is master or slave, since according to the Hardware Specification for the TEAC CD-224E:
"The setting to master or slave is determined by the -CSEL signal (interface connector 47 pin). If the -CSEL signal is at a low level, the CD-ROM drive is set to slave, and if it is open or at high level, it is set to the master."
There are no jumper pins available to set the device to master or slave.
