Windows 7: Copying files to discs (live file system) is EXTREMELY slow

Copying files to discs (live file system) is EXTREMELY slow

I've been burning discs using the Windows 7 built in burner using the Live File System option, but when I drag and drop files to DVDs and the copying files window comes up, it's extremely slow. Like 1.29mb-2.49mb per/sec slow. Any ideas? This can't be normal, it takes a LONG time to for the files to just copy over. When it comes to ejecting/burning the actual disc though, it's really fast so no problem there. I'm also asking this cause if it takes that long to copy over, would that affect read times later on, copying files OFF? Logical but I've yet to test it.

Not sure what else to say. Windows 7 SP1 x64. I've looked for answers already before posting this but no luck. do use UDF 2.50 instead of the default 2.01. Would that influence it any? I did some research and the metadata partition of 2.50 should help in case any of the discs get damaged and need to be recovered, but since it adds complexity, do you think it could be why the copy stage is so long? Once I had a copy session where the speed jumped up to 4.53mb per/sec but it seems like leftfield. Not sure if that one was formatted for 2.50 or not.

Edit 1 (April 12 2012): Quick status update. Just sent some files to a disc that I had started a udf 2.50 session on, one of the slow discs, and it was running at 4.51mb/s transfer. That's new, even for small files it was never that fast. The disc sounded like it stayed running at full speed longer too, it usually would spin up, but then slow down to the point where it's making almost no noise. I think it was so slow before. This time the disc also opened in explorer much faster. I have changed two two things since my last post (both done a couple a couple day ago): 1, I am keeping the discs in a spindle I have. Perhaps they are much more sensitive to debris and a LACK of than I thought. I also uninstalled Daemon Tools along with the STPD drive it comes with and then deleted all the registry entries that accompanied it (only LEGACY would not let me do anything, even after trying to change permissions). I had v1.62 of that on my computer and that harkens so far back that DT was giving a warning saying that it may negatively affect drive performance when installed. Perhaps it did negatively affect me. I read other things that say SPTD should actually INCREASE drive sped though, but maybe that's only hew newer versions, and I'm not taking a chance on that since I don't even use it.

UPDATE 2: Maybe I spoke too soon. 46s to transfer 78.6mb to the same disc happened. And this isn't even starting from the beginning, just when I thought to myself "lets time it". Windows was reporting 800-973kb/s. Ridiculous.

This could be due to the disks you are using. DVD disks come in speeds between 5x to about 32x. What speed are your disks? If the speed is low, try buying some faster disks.

They are non branded Verabatim DataLifePlus 8X DVD+Rs. I even updated my drives firmware. What are your speeds though? Mind trying to see? I just can't believe how this could be normal.

Ok, I have no blank disks availible at the moment to try it out myself but from past experience it should not be that slow. This: Understanding DVD -Recording Speed states that 8x speed DVD's should transfer at about 10.5 MB/sec.

Also, the speed depends on the type of files you are copying. If you are copying one large file, it is often faster than lots of small files.

Try testing your drive with this Download Nero DiscSpeed 7.0.2.100 Free - A CD-ROM benchmark which can test the most important features of a CD-ROM drive - Softpedia and see what kind of results you get

Sorry for such a long reply back. I haven't been burning many discs and I don't visit here often so I kinda forgot to do the test.

I didn't run the full test since it was taking long, but I do the transfer rate and access tests. I can run the full thing if you want me too. The transfer test was however: Start 6.87x End 16.30x Average 12.20x TypeCAV. I let that go for a couple minutes and it kept getting higher and higher but it was mostly not moving a ton so I canceled it. The random seek time was 121ms too.

However the same disc is STUPID SLOW in Explorer, like just browing them and doing simple tasks like right clicking files.

Edit: I just cleaned off the same disc used for testing and it mysteriously started running faster in Explorer. However I keep my discs in near mint condition so no idea what I could have cleaned off. Bizarre. That would explain why it was maybe working slow, but it doesn't account for the other discs. It also doesn't account for brand new discs are taken out of the DVD stack/spindle thingy that are clean as well.

It could be possible you have a bad spindle of disks. If possible, see if you can buy a single blank DVD to test. Also try and see if you can enable dma on your DVD drive if it isn't already. Turn Direct Memory Access (DMA) on or off

I'm gonna run some more tests and report back WAY in the future. DMA was on and I don't want to waste any discs doing tests now, but thanks for possible leads guys!

OK, if you get it sorted post back so other users can help.

If you have any more issues, you know where to turn to!

I found that the following enables you to copy / delete files with far less bother - thing get going instantaneously

Control panel
Programs
Turn Windows features On or Off

To be honest, I'm out of ideas. Hopefully someone else might have a smart idea.
