If you have 2 drives set to master, basically you'll confuse the OS. Set one to master and the other to salve (or cable detect). Have your OS residing on the master and the rest of the drive(s) can be for programs and storage. Windows will recognize each drive as an individual drive
This is a few year old computer and both hard drives are running on a single cable connection, would I have to switch their positions around on the cable to change which one is the master drive to boot the OS?
LOL! Are you saying that you've only got one ribbon (IDE) cable that has a single connector? If that's the case, then you could get a cable that has 2 connectors on it allowing you to have 2 drives on a single cable. That would be the ideal way to set it up.
You could also do this: Reformat both drives. Set one to master, the other to slave. Partition the master drive so part of it is 10gb, then install the OS on that small partition. Having your OS on a smaller partition will allow it to run a little faster. This will also allow you to place certain programs on another partition by themselves, or on another drive and it won't interfere with the OS. Also good if you have a program that requires a scratch disc, you can tell it to create the scratch disc on the slave drive so it won't interfere with your OS. If you set it up like this (10gb partition on the master drive and another drive set as slave) then your computer should recognize it as C: (10gb partition with OS on it), D: (rest of master drive that's not partitioned) and E: (or F: depending on other optical drives) which would be your slave drive. You can also install any program on the slave drive, or use it just for storage of your created music.
As for your old compaq machine, if windows detects an error on the drive, then it won't boot to it, you may very well have a bad drive. You can try to reformat it/check it for errors in another machine, but if it's that old (and you don't really need anything on it) you can just buy another small drive to put in there to get it up and running. It's not out of the norm for windows to not boot if it detects errors on a drive.
Hope this helps! Let us know!
