Hi I am having problems with my Samsung DVD+/-RW drive. When I'm copying a lot of information off a disc or trying to burn onto disks, I get a really low transfer rate (2x on a 16x capable drive), and it slows down my computer a lot. I looked and it is running in PIO mode, even though DMA if available is selected. Here are specs, let me know if you need more:

AMD Athlon 64 3200+
Corsair ValueSelect 2x512mb
Gigabyte K8U motherboard
Chaintec Geforce 6600 256mb video card
Soundblaster Live! 24bit sound card
Western Digital 160gb IDE HD

Hi there

Have you tried defragging the hard drive? I suggest you clear out the temporary internet files cache & the temp folder first, then defrag.

I defrag my HD once a week or so, and I wiped my Temporary Internet Files, which did very little. I seem to have forgotten how to wipe the temp folder though. Plus this is a fairly new computer, it shouldn't be much of a problem.

It is quite possible that using PIO mode is responsible for slowing the data transfer down. Heres a link to a Microsoft article about DMA & PIO modes for atapi drives. You may find it useful :

Other than that, the only other things I could suggest you look at are the way the drives configured (i.e which IDE controller it's on & its master/slave setting) and possibly the programs you have running in the background. You could try disabling some of them temporarily (e.g antivirus etc) & see if it speeds up the transfer rates.

Is your optical drive on the same IDE cable with the hard drive? That can slow things down quite a lot.

No, it is on a different ribbon. It is the only optical drive, and the only one on that ribbon. I can't seem to figure out why I can't get it to run in DMA mode, I've tried uninstalling the drive and reinstalling, but that didn't help. Is it possible that there is a flaw with the ribbon?
