Which Freecom model do you have?
You can find FW for Freecom FX50 model 16B9 2.48 & 2.49 here:
You can often resuscitate a dead DVD by flashing the FW from a floppy disk using the bin file rather than flashing from windows. You need to follow directions exactly and make sure there is no disc in the drive and that you have disabled any direct-writing software that is trying to access the drive. The power must stay on until process is complete.
Search the forum for this and you will find better directions since I have not had to do this my self. Also read sticky
on how to flash from DOS instead of Windows. Good luck.
