I see the same slow read problem where it takes much longer to copy back from the DRU510A than it takes to record (Using my DRU510A I can reliably record a full DVD 15 minutes for all X4 DVD+/-R media brands I have available. I am using XP. Is this an XP problem? I tried several cable changes and master/slave changes with no apparent difference. I also tried using the DOS copy command from the DOS window and found the copy speed is apparently the same as the windows drag copy procedure.
This is a continuation of my last post I should have mentioned that you can get a false (high) read speed if you repeatedly read the same file from the DVD to the hard drive (after deleting the hard drive copy). The file is apparently cached to a hard drive on the first read cycle, and the second cycle copy operation reads from the cache rather than from the DVD. Also worth noting is that the read speed during the Nero verification of a full DVD requires only 15 minutes. How does Nero do it if I can't?
Apparently this is an XP problem with many different types of burners. Haven't found an answer yet as to why but I will try all of your above advice. Thanks
By chance I have done some more copying and the results in terms of read speed are interesting. When I copied a 2.25GB set of many folders and files, Nero required 7:47 minutes burn the DVD and 14:42 minutes to verify. Previously when I had copied a single 4.10GB backup file, Nero required 14:07 minutes to burn the DVD and only 13:25 minutes to verify. When I subsequently drag copied the 4.10GB single file from a DVD to a hard drive, it took about 13 minutes by the system clock. And when I copied the 2.25GB multifile from a DVD to the hard drive, it required about 16 minutes. Also Xcopy takes about the same time as the windows drag copy procedure. DVD caching to a hard drive apparently only occurs with small 100MB type files, larger GB type files are read directly from the DVD even on a second copy operation. So the slow read appears to relate more to the number of files that are read. That is, the read speed roughly equals the burn speed for a single file but is about twice as slow for copying many files. Nero verification is not significantly faster than windows drag copying (as I thought) and perhaps the "slow copying" from DVD may not be exclusively an XP problem. I have no way to test that. Although these results presently apply to only what I measured on my computer system, they may actually be typical.
I finally got the Sony DRU-510A to read and write at high speed in Windows XP. First, install their latest firmware-105.c. The link for that is listed above. Follow all instructions very carefully including the part that says "Disable DMA" within the Secondary IDE settings in the Windows XP Device Manager. The setting I switched it to was "PIO Only". Reboot the machine...twice if you're weary. Then download their DSS speed control software (version 1.0). You have to walk through an online survey that takes a few minutes. Once installed, run the software and set it to "Overdrive". Here's the link for the DSS Software... http://enquete.re-a-son.jp/HVC/510A/ Finally, go back to the Secondary IDE settings in the Windows XP Device Manager and set your drive back to "DMA if Available". Reboot your system. I'm now ripping, err, backing up at decent speeds.
UpInHeaa - Since I find that I can already read a large single backup file at the same speed as the burn speed, do the changes you have made enable you to read back a full DVD of thousands of files at the same speed as the burn rate?
UpInHeaa - Sounded good, so being impatient, I tried what you suggested. I already had firmware 1.0c so I merely downloaded DSS, unzipped it, and clicked on the exe file. Switched to Overclock mode. Then I again tried copying my 2.25GB DVD drive (containing many files) to a hard drive folder and I got the same old copy time, i.e. about 14 minutes, or twice the burn time. That is, I see no improvement using DSS. Even read the DSS instructions! I have a new version of DLA which I disabled but DSS has no problem finding my 510A. So what am I doing wrong?
DonMac - I'm new to the whole DVD burn process so I don't have experience with large single files. I can tell you that when I first installed the Sony, I was ripping a DVD in 40 minutes. After I made my suggested changes, I'm ripping in 12 minutes (Lord of the Rings - Two Towers) Also DonMac - Have you tried changing your settings within Device Manager. Try using both "PIO Only" and "DMA if Available" (changes require reboot). Bisquit - The link to the firmware is listed in previous posts within this thread. Anyway here's the link again... http://sony.storagesupport.com/dvdrw/dru510adwn.htm The firmware upgrade is located at the very bottom of the page after you click the link.
The procedure to make a bootable CD has been mentioned here. I have a question: Is it possible to make a bootable DVD that boots under DOS and reads 4 GB of data from the same DVD disc? There are three problems, as far as I see it: - making a bootable DVD (I can make a bootable CD, yet I am not sure if the same procedure works with DVDs); - after startup of your DOS, seeing the data contained on your DVD disc; - correctly reading a large disk under DOS which generally does not welcome huge partitions. Please share your experience and thoughts.
UpInHeeaa - I got educated some months with my 500AX that appeared to write only at 2X speed, so DMA settings, etc. are in my memory bank. Since my last post I really read the DSS instructions, slow learner that I am, and concluded that DSS in OVERDRIVE simply forces the 510A to use the constant angular velocity or CAV operation, whereas it normally operates in the constant linear velocity mode. I then did some DVD-to-hard-drive stop-watch copy timing tests on both my large single 4.0 GB file DVD and on my DVD that contains a 2.2 GB set of 281 files in 9 folders. On the single large file, OVERDRIVE copying took 8:30 minutes whereas the AUTOMATIC copying required 13:00 minutes. So DSS really has an significant advantage for reading DVDs containing largely 1 large file. On the other hand, the 2.2 GB set of files copy time was 16:24 minutes for the OVERDRIVE mode and 14:12 for the AUTOMATIC mode. So with DVDs containing many files, the overdrive read mode can actually be slower than the automatic mode! Thanks for pointing out the use of DSS. It really does have an advantage is some cases.
I've got the exact same 2x read speed problem with the DRU-500A. Since that drive is very similar I was wondering if anyone know's a solution that will work for it as well. I've got firmware 2.0g but the DSS program from the previously posted link says it will only work with the 510 series. any ideas?
Sony firmware update install instructions... In the updater instructions it says to uninstall and packet writing software, what are all of the packet writing software programs that I must consider? All I could find on my computer was DirectCD format utility, does that qualify? Thanks for your collective help....:~)
Hey all, here's my 2c to this discussion. First, Sony's released new firmware, 1.0d, which is available on their website: http://sony.storagesupport.com/dvdrw/dru510adwn.htm Second, I personally found that using "DMA when available" resulted in much faster read time as opposed to PIO; when making a backup of Bad Lieutenant, the former took about 15 minues to read, while the latter wanted almost 40 minutes. This assumes you're using DSS, of course. So there ya go! Good luck and all, --goolz
Hi, I wanted to ask you some advice on the adjusting the read speeds on the Sony. I've tried using my 16XDVD-ROM drive to read which is been unfortunatly very slow...i think around 2.4x's only. So I tried using the Sony drive to read... and it is just as slow... I just recently purchased my computer last week with the Sony and the DVD-rom drives preinstalled, and i believe that the sony already has firmware version 1.0d. I also downloaded the DSS selector from sony's website. But, when I try to install it it prompts me to disable any packet writing software? What does that mean? I dont want to do anything rash and screw up my drives' settings, or my dvdxcopy platinum's setup. Could you please advise? Thanks, much appreciated.
Packet writing software would include software such as Nero, Roxio and Adaptec. It's a good idea to uninstall these software packages ANY time you install a new CD or DVD burner.
do you know if i need to uninstall my DvdxCopy Platium as well to install the DSS? or is XCopy not considered packet writing software?
I don't think you do unless DVDXCopy also writes the DVD's. The only experience I have with DVDXCopy (and someone please correct me if I'm wrong) is that you can't make copies of your DVDXcopy copies. I've heard that the following procedures are decent... Extract/Copy data from DVD with DVDDecrypter Compress data with DVD2One Write with Nero Express 6
