CR ROM NOT WORKING PROPERLY

I HAVE 2 COMPUTERS 1 WIN 98 1 WIN NT 4.0
BOTH W/ SAME PROBLEM. I GET ERROR MESSAGE
“F DRIVE IS NOT ACCESSIBLE DEVICE IS NOT READY” THE DEVICES ARE NOT SHARED ON NETWORK
WHEN I CHECK THE PROPERTIES IT SAYS DEVICE IS WORKING PROPERLY. I’VE DELETED DRIVERS AND RE INSTALLED TO NO AVAIL. ALL DRIVERS SEEM OK STILL NO CD ROM ANY SUGGESTIONS?
