Any problem w having HD & CDRW on same ide?

Nope, that's the way suggested by some.

If you run a CD-ROM and a CD Burner on the same IDE you can get clicks and pops in recorded music, I did.

Swapping it to your way solved the prob.

if u have a cd-rw on the same IDE as a HDD they may "conflict" someone i know had this prob and found that when they unistalled Windows 98 the problem was fixed. The problem was that the cd-rw was only recognised as a cd-rom...OR only a cd-rw...

I suggested that the primary+secondary ide 's were not configured correctly...

The problem with having the hard drive and the cdrw on the same ide cable is the drives will only go as fast as the slowest drive out of the two.

I do believe that this is correct anyone else have any input on this???

Gee doc, I got the clicks and pops if my machine so much as moved a muscle when it was writing. Then I got Nero and it quit. Oh, I forgot, also went from a 500 to a 800 and tripled the ram.......

The problem with having the hard drive and the cdrw on the same ide cable is the drives will only go as fast as the slowest drive out of the two.

For most newer motherboards and chipsets, this is no longer true.
If they support "device independent timing", there is no penalty.

This is usually indicated by "dual fifo" in Device Manager/Hard disk controllers.

In general, this will be the case for any mobo that supports 100MHz FSB or higher.
The protected-mode IDE drivers included with Windows may need to be replaced with
chipset-specific drivers (VIA for example) from the motherboard manufacturer.

There can be other conflicts when a CD-RW and its source (HD or CD-ROM)
are on the same channel, however. No controller can perform a read and
a write operation at the same time.

Hi there,

I don't think there should be any problems with having a CD-ROM drive and a HDD on the same IDE channel. I have both my old (a ATA-3!) and my new (a ATA-100) on the same channel. The new one runs a lot faster (compared to the older one) and is hence not forced to run at the same speed as the old one.

I have also seen systems with both HDD and CDRD on the same IDE channel. The HDD seems a lot faster than the CDRD.

So the conclusion is that the faster device is not forced to run at the speed of the slower device. Although this could be false for old hardware.

With dual fifo, there is less of a problem. As a habit though, and to avoid conflicts, I run the hdds by themselves.

Thats my config and I have no problems whatsoever!

It's not so much that the two devices on an IDE chain run at the speed of the slower device, it's that the computer can only access one device on a single IDE chain at a time. If you often burn from your hard drive then you may (but not necessarily) have problems.

I usually have my hard drive and my CD-rom on the primary channel with my CD-RW all alone on the secondary. CD-RWs are usually happier as a master device anyway. Good luck.

"The problem with having the hard drive and the cdrw on the same ide cable is the drives will only go as fast as the slowest drive out of the two"


I thought that it was as slow as the master, meaning if your slower device was master, the slave would be slower too. But I'm even beginning to think thats wrong as well, for the newer motherboards like Psycho Said. Example: Sandra HDD benches, Master-5400 rpm WD drive score of 8930, Slave-Maxtor 7200 rpm score of 21,000. Sure the master has the OS on it, but the scores shouldnt be that much different. The master was also freshly defragged

I agree with Eli on this: run the CDRW as a Master. I run mine alone as a Master on the Secondary Channel per instructions that accompanied my Plextor CDRW - never had a problem. My HDD(Master) and CDROM(Slave) are on Primary channel.
