Dirty Disk Problem with DVD+R Disks on SONY RDR-GX300?

I'm having lots of "dirty disk" problems when I try to record on DVD+R disks in my SONY RDR-GX300.  The ones giving me a problem are Memorex (both 4x and 8x speeds) and CompUSA (4x speed) generic brands. Any information or advice to help me with this problem?  I have had absolutely no problems recording on DVD-R or DVD+RW disks -- not even one failure in dozens of recordings.  (I have not tried DVD-RW, so I have no experience with that format.) I would just avoid using DVD+R disks for recording, but I got a bunch of them as a gift and want to use them up if possible. Thanks. Goodler SEVEN OUT OF TWENTY +RW DISKS FROM MEMOREX WILL NOT FORMAT-(DIRTY DISK) Have the RDR-GX300 recorder. I get frequent "dirty disc" and "cannot play this disc" messages. Sometimes wiping the disk with a soft cloth works, but lately nothing works. Brand new discs get a little into the formatting and the error messages start. It's about 2 1/2 years old and it was not cheap. My cheap Wal-Mart machine is more dependable.

I have used my Sony GX300 for a couple of years and love it. I prefer +R blanks. The only occasional problem is the media brand. It will not record Fuji 16X, but will record Fuji 4X, which are rare nowadays. I have used TDK 16X with success, but this week bought TDK "lightscribe" blanks, and the GX300 would not record with them.

Sony should provide an upgrade download for the GX300 but does not. On the internet I have been unable to find a list of suitable brands for this DVD recorder, so I have to take risks when shopping. Fortunately, all blanks can be used for my computer so my money is not really wasted.

It's October, 2009 and in Toronto there has been a shortage of DVD blanks for months. I've been told there will be lots available in December.

I had the same problem which was easily solved by only using VERBATIM or TRAXDATA blank R or RW disks. All others including Sony's own disks would NOT work properly !

Think you have the solution already, stick to Sony brand DVD-R disks. The +R could be traded to someone you know, and would probably work fine in a PC.

My Sony RDR-GX300 DVD Recorder is suddenly only recording the 1st 15 seconds from the DVR. The entire show is on the DVR. I have tried discs that I've used before successfully & new DVD's.

1) pass the Disk cleaner buy to some radio schack, and test it
2) test the cable in another device, and determine if faulty or not.
3) if not clean the terminal from DVD VS TV with c.cleaner
4) otherwise the Syscom inside and another associates circuit is faulty such like record ampl.
go to the repair shop for fix it.
God bless you

When I burn a DVD (R- or R+) on a Sony RDR-GX300 it burns the DVD which plays on that unit only. If I try to play the DVD burned on Sony RDR-GX300 on any other brand or any other Sony DVD player or even on...

On That Type Of DVD Recorder,( RW,R-R+). You Will Have To Finalize The Disk. Finalizing is Necessary When Playing On Any Equipment Other Than This Recorder.Even IF Your Other DVD Equipment IS ( VR ) Format Compatible You Still Need To Finalize The Disk. After Finalizing,You Cannot Edit or Record on The Disk,Make Sure It's In Video Mode.

Unit cant recoginze/ read a disk


I had a dvd-r disc recorded from a Philips dvd recorder that had not yet been finalized when the Philips went bezerk and died. I replaced it with the Sony GX300 and just for an experiment, tried to finalize it in the Sony

It worked. Not to say that it has to work with only THIS combination of the 2 same dvd recorders or twisting the scenario around with the Sony doing the recording and the Philips doing the finalizing. I also have a Sony dvd/vcr recorder to compliment the GX300. I will have to record a disc on the GX300 and try to finalize it with the combo unit to see if it will do well as a back up.

Right now a disc that is not full yet (home movie from my kids birth) is reading "Disc Error" on the GX300. I may have to do it over or see if the combo unit will do the same finalizing as the GX300. It doesn't have the amount of features that the GX300 has but thats what you get with a combo unit vs. a stand alone recorder/player.

If you know someone with another recorder, try to finalize on it. If not , you could find someone on this sight that has a GX300 and mail the discs plus a smalll fee and have them mailed back. Or you could find a used one cheap at some store and return it if it doesn't finalize.

Good luck

Disc Dirty

Reportedly, the WR/R drives that Sony installed in these and other similar models have a technical defect. They will work for about a year or so of moderate use and then start having problems reading the disk. Eventually they quite working entirely. Internally the drive is removable and looks somewhat like any other computer DVD drive. Unfortunately you can not just replace it with a standard drive from your local Best Buy store. It is a proprietary drive with a special cable and firmware on the motherboard specifically intended to work with their own equipment. If you contact Sony tech support they WILL NOT sell you a new drive. They don't allow consumers to repair their stuff, you have to send it in to their service center where they can charge you up the wazoo to fix it. When one of these units dies the best solution is to go on line and find a refurbished unit to replace it. New ones are about impossible to find because they are being discontinued, and buying a "used" one will be questionable since it already has who knows how many hours of use on it already and will just develope the same problem. A refurbished and repackaged unit will be the same as new but with a factory replaced drive.
