Will a Hard Drive Slave Slow a CDRW Master?

I have a new TDK 32/10/40 that is running great alone on IDE 2, as master. If I were to add a slave hard drive, would it degrade performance of the CDRW? I only plan to use the hard drive for backups. Would it help to set Power Options in XP to shut off hard drives after a time? I assume this would shut off a backup drive that only gets used once a day. Thanks!
 
The answer to your question is yes it will effect performance. Anytime you add a slave device on an IDE controller there is a decrease in performance. The question is whether it will be enough to effect your CD-RW to possibly cause errors. Chances are that it will be fine. The best way to find out for sure is to hook up the hard drive and run some burn tests on the first 5 or so CDs you make. If they pass through without a problem then you are okay.

As for the power option, that won't help with the performance.
 
If you are going to be transferring to/from 1 device at a time you will not incur any penalty for having both connected to the same IDE channel. Now, since IDE does not support 2 devices on the same channel transferring data at the same time, you may have some problems if you are buring from that hard drive to your CDRW. That should not be too much of a problem since your CDRW should have some sort of buffer under-run technology. Over all, I would not worry about it.
