Cdrom & burner on separate cables or together?

belveder · #1 13-03-2003, 17:15

Out of curiosity, I just bought a new hard drive that is 80 gig, 7200 rpm, ATA 100 with 8mg cache but my old hard drive is 30 gig, ATA 66 and runs at 5400 rpm. I would like to run both (preferably with the OS on the older, smaller one) but I read somewhere once that you can't. I read somewhere else though that the new drive should be on one IDE cable with the cdrom as slave and the old on another IDE cable with a burner as slave. But if the old drive is lower ATA and RPM that the new one won't the new drive slow down to the capabilites of the old? Also, wouldn't that affect burning separating the cdrom from the burner?

My system is only a Celeron 850 with 640 mg ram on an AOpen mobo

Can someone please tell me if you can or can't mix the drives? And if so, will having the cdrom & burner on separate cables affect burning?

Thanks in advance

It is better to put your burner and cd-rom on a diferent cable because if you are burning on the fly you don't have to read and write on the same bus (but ide is today most time fast enough).
Clonecd is checking of your reader and writer is at the same bus and if so then it give's a warning.

I know that if you are putting a slower harddisk on the same bus as your new harddisk then the both drive's will run on the speed of the slowest harddisk.
I don't know for sure of the cd-rom also give a conflict with the harddisk.

So my idea is mix them.

A point to note. To get your new hard drive to perform at ATA100 you have to use an 80 wire ribbon cable. If you connect with a 40 wire cable it will run at ATA66.

Does your motherboard support ATA100. A good sign is IDE 0 normally has a blue connector.

I have the 80 wire cable and the mobo supports ATA 100 no problems. My CPU is only an 850, I was thinking of keeping my old HD to run XP on ATA 66 5400 rpm and the new one for everything else, would this work?

Say
Master = old HD with OS
Slave CDRom

Master = new HD
Slave = burner

how would this run and would it affect burning?
Thanks in advance

by that logic, putting a cd drive on the same with a hard drive would cause both to run at the same speed? ata 33 for a lot? im not inclined to believe this - philamber @ cdfreaks has told me otherwise

That was the reason why I put that already in doubt. But with a harddrive it's true.

Or somebody has really make me something up.

post / search in cdfreaks hardware forum. they'll set you straight.
