Basic hard drive question?

[Jhill]

My primary hard drive is ata 100 7200 rpm. If I add a ata 66 5400 rpm as a second drive on the same IDE cable will it slow down my primary ata 100 drive?

Thanks for any help.

No it will not, the ata100 will continue to work at ata100 & the new ata66 will work at ata66.

All current chipsets support independent IDE device timing.

And even if it did fall back to 66 (which it doesn't), you would not notice the difference. Don't worry.

Thanks for all your help. I have a friend who is convinced that the ata 66 drive will slow down the ata 100 drive to ata66 speed. Could someone point me to a reliable website or something that explains that my master drive will still run at ata 100? I would like to send it to him.

Again thanks for your help

BTW I am running on an ECS K7S5A

That only applies to a SCSI confiruation... not IDE

If it were a SCSI setup, you're limited to the slowest drive that's on the controller channel.

Whitedog, correct me if I'm wrong, but I thought newer SCSI adapters were also able to
handle independent timing for devices as long as it could allow for switching between modes.

The ECS K7S5A should have very good IDE performance!

By the way I have an ATA 133 Drive @ ATA 100 and a ATA 33 drive as well as a Pio mode 4 drive! I have had them all working together at various times! The ATA 133 drive always works at ATA 100 ( ATA 100 controlller ), the ATA 33 drive always works at ATA 33 and The Pio mode 4 drive always works at Pio mode 4!

By the way I have them all on an ECS k7S5A
