Hello, I’m new here. If you don’t want to read all of the rambling about my system and the issue, just skip down to the big italicized question. I want to be thorough, so that if this problem is deeper than I think, then you will hopefully have enough info to go off of to give a good guess at what the issue is.

Software: I run Debian Sid GNU/Linux exclusively, and currently I use dvdbackup to rip either the full disc (if it’s a single-layer) or the main feature (if it will fit on a single-layer disc). I also use DVD Shrink 3.2 in Wine (as much as I hate Wine, I have yet to find a native proper shrinking tool or script) to rip and shrink dual-layer DVDs. Some movies I rip to Xvid4 using dvd::rip. For burning, I usually burn ISOs with Nautilus or growisofs.

Hardware:

Athlon XP 1800+ / 512MB DDR

Primary IDE Master: Maxtor 5T030H3 30GB HDD (unknown mode)

Primary IDE Slave: Lite-on LTR-12101B CD-RW LS3I (MDMA2)

Secondary IDE Master: Maxtor 6B200R0 200GB HDD (unknown mode)

Secondary IDE Slave: LG HL-DT-ST DVDRAM GSA-4163B A104 (UDMA2)

It is weird because when I check the output of hdparm -i, the two hard drives do not have an asterisk beside the mode that they are in. During boot, the BIOS says UDMA4 and UDMA6, if I recall correctly. In any event, all of the devices have 32-bit IO support, unmask IRQ, and DMA enabled.

The OS is installed on the 30GB drive, and all of my own data is stored on the 200GB drive. Everything that will be burned is stored on the 200GB drive.

Now, the issue is this:

Sometimes when I burn DVDs, it takes an hour or two, and other times, it takes only the expected 15 minutes (this is at 8X with 8X supported (but inexpensive) media. I’m not entirely sure why exactly that is, but I can sit here and watch the speed fluctuate from 7.8X and down to 0.9X… That’s not so good. Usually once it hits 0.9X, it doesn’t come back up. It doesn’t matter if I burn as a user or as root either, the same thing happens. Sometimes it starts off at only 0.9X and stays that low for the whole burn. Other times the average is somewhere in between. For an example log from growisofs, scroll down to the end of my post.

The question I have is this:

[size=4]Should I rearrange so that my main data drive and my DVD burner are on different cables, or is my current configuration fine? If I should re-arrange them, how do you suggest (keeping in mind that at least I prefer to keep my OS drive as the primary master)?

If you do not feel that this issue is related to the IDE configuration, I’m open to other suggestions as well. Any insight is appreciated.
