This is also why the HD (horse) should be on the same controller with the HD (horse) and not with the CDROM (chicken). I was not referring to the master/slave thing; I wanted to point out that having different devices (HD and CDROM) on the same controller is not good. > This is also why one device per channel (port) is desirable, and a > controller card is best to use if a mobo only has 2 IDE ports and you > wish to add another HD if you already have an existing HD and CDROM > drive.

I guess I mistook your point; I just wanted to say that the "canonical" connection would be like: Primary Master: HD 1 Primary Slave: HD 2 Sec. Master: CD-RW Sec. Slave: CD-ROM And if HD2 rotates max at 5400rpm while HD1 rotates max at 7200rpm, then under this connection HD1 will rotate at 5400rpm. > Doug, since it's no big deal to change them around, test it > yourself. There's also a small executable raptest.exe (or something) that is used mainly for testing the overlay capabilities of the graphics card. Apart from this, it has a built-in HD test utility. > "i.e. if there is a CD-ROM drive on the cable > you are putting it on, you will want to change > the CD-ROM drive to slave and set the new > hard drive as master." That's true. But connecting a HD on the same controller with a slower device (CD-ROM/CD-RW/DVD/super-chicken) does not let HD run full speed. ============= PCWorks Mailing List ================= Don't see your post?
