Will not reconize Memorex blank dvd-r'sometimes

When I use memorex and sometimes other brands of blank dvd-r's.After I put the disk into the drive it all what happens is the light on the drives outside front stays on and it won't turn off thus I can not burn.I just keep using disk until it dose turn off.But here is the kicker.When I reboot the pc the disk that it would not recognize it will now,until 3 0r 4 burns then it starts all over again.Now I have updated the firm ware to the latest to LLOC for that drive.I am wondering if it's the disk that or causing the problem or the drive itself.

What BRANDS are compatable w/ HL-DT-ST DVD+-RW GSA-T21N?

I hate to say it but memorex are the worst quality,the reason is that the drive's laser will try to adjust its power upward to burn the disk-optimum power calibration(OPC).Some burner programs display this . I have tried over 8 packets of different memorex media and results are poor ,one in five are coasters .I suspect memorex media will destroy drive lasers as running laser at top power isn't good for its life .I hate to recomend brands but tayo uden,verbatim and sony are good media but not as cheap as memorex but more cost effective!

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

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.

Won"t see blank disc

given my experience with memorex blanks, i think that you should just switch to another brand....memorex made great tape....the cd blanks are another story. I recommend, if you can find them, FUJI blanks that are made in Japan; they have a reputation as some of the best.

When you get no disk error, that is because of a problem with the optical laser lens that is dirty, faulty or opaque, and will start operating on certain disks better than others. Often the problem get worse in time.
Try first using a DVD lens cleaner disk to clean the lens. If that does not work you will need to disassemble the drive , and clean lens directly with q tips and isopropyl alcohol, or to replace the DVD lens, or the whole drive unit.
