This is kinda OT. I have 4 drives in my system. Every time I copy some files
from Cd or DVD to hdd, my computer slows down very much. Sound gets all
shaky and movies slows down in fps.

2 Harddisks, connected to first IDE port. 1cdrw and 1 Dvd rom connected to
other IDE port. Is this correct way to connect them? Or should it be 1hdd
and 1disk drive on each IDE port?

Thanks for replies

Sounds like your optical drives are using PIO transfer modes instead of
UDMA. You didn't tell what OS you're using, but in Windows[1] open the
Device Manager, open the properties of the IDE channel the drives are
connected to and on the Advanced Settings tab choose "DMA if available"
for both drives. Click OK, reboot and you should be in business.

yes i agree, make sure all your drives are using Ultra dma mode.

also make sure that it (UDMA/ATA) is set to AUTO or enabled in the BIOS/CMOS setup

Thanks for replies. I am using WinXp pro. I will check my bios settings
during next reboot, and tell if something's wrong.

Thanks
 
IDE 0 - First connector - Master, end connector is slave. Ensure the
jumpers are totally correct on the drives.
IDE 1 - Same as above

Do not put a CDRom drive on the same cable as a hard drive. Two hard drives
on one cable can result in slowdown if you are heavily using both drives no
matter what your system is.

Did you install the mb's chipset drivers?

The end of the cable is the Master, the middle connector is the Slave.
IDE 1 - Same as above

Why?

Two hard
drives on one cable can result in slowdown if you are heavily using both
drives no matter what your system is.

Indeed. Which is why it's sometimes sensible to put opticals on the same
cable as modern hard drives. Hard drives can read at around 50Megs/s - an
Optical drive probably less than 10Megs/s

The best combination of depends on which devices you tend to transfer to and
from. For example, burning CDs from CDs I'd say put the drives on seperate
channels, burning from HD to CD, put them on separate channels. It depends.

Yep. It's a via kt133a chipset, so latest via 4 in 1 are in place.
However, I think that problem is now gone. I looked in bios and master/slave
settings for ALL 4 drives were set to NONE. I just set them to Auto and
voilà!

Yea, that will do it. :-)

It used to be a problem, but it seems later generation of UDMA
controllers have removed this limitation, so my statement was incorrect
for modern machines (Intel's controllers removed the limitation in the
PIIX4 controller, before the PIIX3 controller a slow device on the
secondary channel would slow down devices even on the primary channel! I
assume VIAs controllers have removed this limitation as well.)

Correct. It's still a good idea to keep a CD/DVD burner you write TO and the
drive you write FROM on separate channels. That often turns out to be the
same thing as the old advice.

For example, I use a DVD-ROM to rip to my hard drive, and then burn the
files from the hard drive to my DVDRW. So I have two hard drives on IDE 1&2,
cable select; and the burner and DVD-ROM as master and slave on IDE 3&4.

Other combos will work, but this one seems optimal. One notable exception is
systems with Highpoint RAID controllers, which work great with hard drives
and get squirrely with CD/DVD drives. I've heard the same is true of some
SATA controllers and adapters, but I have no personal experience in that
area.

It seems many of the "Rev 1" PATA to SATA adaptors didn't like ATAPI
devices, but I think thats mostly sorted now.

Dammit. Sorry about that!
