Driver Upgrade problems

This DVD/CD read-write unit will not function in CD mode. Windows XP recognizes the drive. Performed self-diagnostic =OK. Downloaded driver file 716a_111 from Plextor. The executable file stalls near completion with Error Code 04-40-f6. The driver currently used is Microsoft 5.1.2535.0 dated 7/01/01.
I’m perplexed.:sad:

If you have 716AL, then 716A firmware will not match. Last firmware for 716AL is 1.03 (I think).
If your drive stopped writing and/or reading cd, it may be defective, a new firmware won’t fix it :confused:

To be sure, can you try it in an other computer ? But if it write/ead dvd correctly…
