Sony DRU700 Problem

Hi all

I purchased my sony burner about last month and have made a few successfull backup copies of my movies until now. Im using InterDvD Video Platinum2, the media i used was Verbatims -R. For some reason my DvD player wont pickup the disks and it just displays an error message. The discs play fine in my PS2 though but it takes a hell of a long time to spin up.

the copies i made arent readable in my dvd burner itself, what i mean is i cant see any data on the cd once ive written it, just says that the cd’s file system is RAW.

Does anyone have any suggestions. Im using firmware VY06


  1. go through the 10 points listed @ [ you may not be a newbie, but the trouble is, and might be related to one or more of the listed items ]. note: very important to keep the transfer mode on IDE channels in DMA mode. check them every now and then, they can change.

  2. a) know your drive’s capabilities. use nero info tool. also go to the drive maker’s website and find out what media types and brands, and at what speed to those media types, the drive supports. [ eg., my pioneer 107d can burn to dvd-rw @ 4x without trouble, but my optorite 401 can only burn @ 2x to dvd-rw even though Nero and other burning programs will offer to burn @ 4x and will produce a “successfull” disc @ 4x…it ends up a coaster ] b) update the firmware of the drive. check for updates @

  3. a) try another brand of CD/DvD disc. b) try burning at lower speed. eg., don’t try burning at 24x to 16x media; burn according to MEDIA speed limits, don’t try to burn at the cd/dvd drive max speed until you are certain that you can do so without negative consequences.

  4. a) disable and/or uninstall any virtual drives. b) install an aspi layer. preferred is v460. get it @

  5. a) update the burning program you are using to the latest release. b) uninstall any recently installed software. c) do a virus scan, and a scan with spybot s & d [ get it @ ]

  6. for XP or Win2K users, optimise your operating system Services for best system performance. for info go to and

  7. before burning, open taskmanager and shutdown ALL unneeded processes that are running.

  8. a) try another burning software and see if you get a better result. deepburner standard is free. get it @ b) for users of alcohol 120%, update to the latest drives support DLL [ look for topic “Alcohol 120% Device Support Patch Released” @ ] c) if you have multiple burning softwares installed, uninstall them all, then install one. test it. install another if needed. test it, and so on…

  9. make sure mainboard chipset drivers are up to date. make sure all cables and jumpers connected to drives are correctly configured with regard to master/slave setup.

  10. enter your BIOS and disable anything you don’t use. set memory speeds to default. set cpu speed to default. if you overclock, DON’T [ until you are certain that overclocking is not the cause of the trouble ].

  11. if you still cannot fix the problem, try the drive or the DvD disc you are having problems with in another PC that has no burning issues…if possible.

Thanks, i’ll start troubleshooting later.

You could also try giving DVD Shrink and DVD Decrypter a shot. However, I do believe that this is a media issue. Don’t let the name brand fool you. Verbatim can varry a bit in quality in terms of where they are made. Check on your spindle and see if you can tell where they are made (it should list it somewhere on the spindle label).

Well i downloaded a utility from the Sony website called DriveCheck and tested the drive. no errors were reported and the drive passed all tests. so i’ll probably have to look at one of the other possibilities.

The Sony 700 is a rebadged Liteon 832. You can run Kprobe2 on the burned disks to check error rates. You can also use the liteon Booktype setting utility to make +R’s into DVD-ROM booktype. This drive has generally better burn quality on +R than -R (at least in my experience). Have fun!

Thanks, im busy downloading kprobe, i’ll post the results later. i re-burnt one of the movies i was was having trouble with earlier jst as a test on a Verbatim +RW and played it in my player. No problems whatso ever, im just worred about the fact that -R media is a problem for this drive.

Nothing to worry about, just use +R. If you want maximum compatibility with settop players you can bitset the +R media to show DVD-ROM Book Type. This fools players into thinking it is a commercial pressed disc. The guys over on the Liteon subforum can be more help if you have trouble or need help interpreting kprobe scans.

Thanks alot for all your help, i actually did purchase a 5pack of +R Verbatims.
