SubjectWhat regulates CD recording speed? Reply to this message
Posted byDeath Knight
Posted on01/27/05 11:05 AM



Is it just the HD speed? 'Cause my drives max out a 16x. If i put it to burn at 24x, it stays at 20x for a minute then spins down to 16x and stays.

I moved up the processor and ram ( 1800 266 to 2800 333 ), but that had no effect. Would the only way to speed it up be a faster HD? ( this one is 7200rpm, the next step would be SATA )

A CD burn at 5-6 minutes ain't bad, but being stuck with 2x DVD burning isn't fun. 30 minutes a pop is pretty time consuming.

SubjectCD or DVD? new Reply to this message

With any modern PC (< 5 years old), the machine itself
isn't limiting factor.

What limits you for CD burning is
- the speed of the drive (most drives now are 40X+)
- rated speed of the CD-R media (most all media burns at 40X+ now)

What limits you for DVD burning is just like CDs: the
speed of the drive and speed of the media. The quality of
DVD varies widely though (just like CD media years ago) so
get good media. Videohelp.com has ratings to help you out.

It sounds like you are trying to burn a DVD at 2X speed,
which takes a half hour or so. Buy a faster drive and
media that is rated faster.

I'm currently using my old CDRW drive since my DVD went kaput ( still had a warranty, it's being exchanged ), which is a 40x12x40. I'm using Samsung 52x and was using Smart Buy 4x for DVDs.
That can't be the only factor.

SubjectSomething with your HDD maybe new Reply to this message

Try disabling your antivirus before you burn and see if it goes faster. I've seen these on some peoples' machines take up over 60% of the CPU cycles, and certainly a lot of IDE bandwidth!

Do a HDD benchmark. Your drive is 24x, that means your burner should reach 24x by the END of the burning cycle, and 24x150k = 3.5MB, so I guess you should benchmark your hard disk but I'm pretty sure it could manage that.

Other than that it would be the bandwidth of the IDE channel. You should have your burner on a separate IDE channel, its own cable, to get the fastest performance.

But everything's sharing the PCI so unless you have something like HyperTransport or VIA's V-Link or something like that you won't be accelerating PCI transfers over DMA to their fullest potential because PCI is just 33MB/sec by itself.

So if you DO have V-Link or HyperTransport then that wouldn't be the limiting factor. But maybe DMA isn't enabled on your CD-R or something, you should check for that. If you have a VIA board you gotta get the 4-in-1 drivers.

Now if your drive is fragmented, the speed would be limited by seek time, and the r/w heads would be jumping around all over to read the full file, so in that case you should defragment. If you have any hard disk errors (run chkdsk/f/x/v and reboot) that might be slowing things down as cluster errors may prevent files from being read as fast as they should but only if you're trying to read damaged files...

I dunno what else it could be

That's how long it should take with a 2x burner :/ With a 24x burner it should take 5 minutes max, you could probably get a little more speed out of it it seems like. But not a huge difference.

Make sure the cd burner is not connected to the same ide channel as the harddrive. The harddrive should be also using an ata66/100 cable (80 wire).

Harddrive should be primary master, burner should be secondary master. Only 1 device can use an ide channel at a time even though 2 can be connected simultaneously.

Done, checked out fine. About 50MB/s.

Checked. There are two IDE slots on my mobo. One hooks up both my HDs and the other is for the optical alone.

Ok, how do i check if that's enabled or not? ( my mobo is a VIA btw )

Kinda lost me there. How do i check the DMA (edit, ok, i checked, it's enabled as multi-word(?) DMA mode 2) and what 4 in 1 drivers are you talking about?

Nah, i always keep my HDs perfectly defragged. I use the slower one for downloads and the faster one for storage and burning. The

Yeah, if i can get this speed-lock issue in check the max i'll get is 4x anyways. My DVDR was 8x, probably gonna get a 16x for the exchange, but I can't seem to find any media around here over 4x. :-\

It's just a hardware feature, either you have it or you don't. It would be listed in your manual or on the web site for your motherboard...

The DMA setting would be in your BIOS:



Gotta enable all that. Then you have to check in Windows to see if it's really enabled (should say in device manager or something). If not, here are some things to try. Also you have to be sure your devices support DMA mode but it's rare to find some that don't.

The highest possible mode... if multi-word is the highest possible setting than set it to that, but usually it's called DMA mode 1, DMA mode 2, DMA mode 3, etc just like the various PIO modes.

The 4-in-1 drivers are here somewhere (you used to be able to directly link to the driver download, but not now, sorry) and ensure that your hardware capabilities are used since Windows does not normally come with the most up to date chipset drivers. The 4-in-1 drivers, or "Hyperion" as they are now called, are the name of VIA's chipset drivers (instead of "driver" nVidia calls it "Detonator" or "ForceWare", ATI calls them "Catalyst", etc, it's just marketing). It used to be called 4-in-1 because you'd get an AGP Gart, IDE driver, Chipset INF files, and PCI routing driver. These are all very important to install to get top performance!

Ohhh I see. I thought it was 2x max.

But if the data is going from the hard drive to the CD-R, over the same channel, that means that neither device is getting exclusive control of the channel and are forced to negotiate, so it's probably not as fast as it could be.

Some DVD-/+RW's are "smart" in the way that the firmware recognizes media codes and only burns them at what the manufacturer believes them as safe (as in you buy shitty dvd-r's but the manufacturer of the discs rate them at 4x, the drive may only burn them at 2x if that is what the manufacturer has set.) So its important to keep the firmware uptodate so incase new media codes appear you can run them to the best of your drives ability.

Its basically to limit complaints to the manufacturer of the drive about burning coasters, when the real fault is with shit quality discs that are rated higher than they technically should be (speaking of smart buy, i burned some cdr's from them... disappointing to say the least. They were the 1st batch of CD-Rs I've had peel on me where the metallic layer on the cd just flakes off).

Additionally some drives are setup to also read similar codes on CD-R/W's and limit their burn speed, but that normally happens upon detecting the disc (nero will only let you burn the disc up to a certain speed.) The only time I've seen the burn speed drop after you selected one, is using shit quality DVD-Rs (my friend bought them to burn himself some stuff on my drive) and my Toshiba at the time didn't like it. Have a LiteOn 1633S flashed to a 1653S now and I love it, especially with the firmware editor.

I had to install the VIA IDE Miniport driver because Windows XP's included Secondary IDE Controller driver was being retarded. It's not a part of the 4-in-1's anymore (at least, not for 2000 and XP users) so you'd have to download and install it separately.

I had 32x princo that I could burn up to 24x and sony 16x media that I could burn up to 32x. Some media works better with different burners.
