Hi bobsscgirl, here is a link to the firmware for the drive TSST TS-H653Z Optical Drive Firmware Update - HP technical support (United Kingdom - English) It's the only one I could find ,It may be the original firmware so don't do anything with it yet ! Also have a look here TSSTcorp CDDVDW TS-H653Z WONT BURN ANYTHING - Microsoft Answers it may be of help .
Even though your drive is internal it still uses a cable to connect it to the motherboard ,sometimes unplugging and replugging the cable back in can remedy problems but if you have a spare cable lying around try that one ,cables can fail
