@ShdwStrdr You can give the A07XL 1.22 a shot. No where in any progs or device mgr. is my drive listed as an A08XL yet that is the only firmware it will take. If that doesn't work well there's always Pioneer support. Another thing I would do is upgrade the discs your using to Taiyo Yuden or Verbatim. Keep us posted! Edit almost forgot - try disconnecting the ASUS drive and then retry the the firmware. It may only be seeing that drive.
Blinkie will try the other firmware version. always have used Verbatim, lately been using the JVC's without any problems. -R The brand in device, I believe it RiteW is the +R my son bought from the game store he works at. He wanted me to backup a bunch of anime that he has and that is what he brought home. That is how all this started with the plus's. Ive got all that up and running now it has migrated over to the firmware issue. Appreciate all the help, will keep you posted.
@ShdwStrdr Those discs you're using are made by Ritek - (from your log) Ritek is okay - some members here love it others don't. I'm not a fan - stopped using it awhile ago (burn & playback issues) Try disconnecting the ASUS drive to update the firmware- also everything is on the same channel - may be the problem with the firmware not recognizing the drive. You may want to put the drives on a separate channel from the hard drive.
@ShdwStrdr Finally success :0) - It's usually much easy this than this!! Hopefully that will do the trick with those Riteks. I know how kids are - even older ones- with their anime (well mine at least!)
