Hard drive setup on ide chain....

[fitzhue]

Just a quick question, I have an ibm 30g 75gxp and an old quantum hard drive (ata33). If i have these two drives on the same chain, will the quantum slow the ibm hard drive to an ata33 speed? Thanks

I believe the correct answer is yes, if they are on the same ribbon. I believe that there has been some problem in the past using differing EIDE/33/66 drives on the same ribbon. I ran into it with EIDE and /33. A cheap solution might be a simple Promise/66 controller card for the /66. Pretty cheap now. Actually, from what I've read, you won't see /66 xfer speed anyway. Supposedly, they normally can't even max out the /33, unless they are RAIDed.

IME, where you'll notice the difference in the drives is in the rpm, probably 7200 vs. 5400.

bump, anyone?

what if its a hard drive and a cd-rom or cd-rw?

If I were you I would use the new hard drive as the primary master using an ata66 ribbon cable and the old drive as secondary master, leaving the cd-rom as secondary slave. You may need to install the intel ata driver depending on your setup. The ata66 cabel will have a small notch cut out of it but this is normal.
