Anyone has compaq DRN-8040B firmware?

I’m trying to fix a friend’s compaq drn-8040b Laptop drive which doesn’t read CD-rom, but reads DVDs just fine. It’s actually a LG DRD-8040B drive I think(slapped with Compaq name and some small firmware change I guess). Can anyone who has this drive kindly send me their firmware so I can try to fix this drive? Can’t find the firmware anywhere so…Or perhaps one of the gurus here can point me to the flash utility that allows flashing of a 8080B firmware into this drive. I figure 8080b is similiar to this model so…

Thanks to all for reading/replying this. :slight_smile:

Flashing a firmware would probably not help here.
Use a Lens-Cleaner or disc and try it a few times.
