i recently decided to install a 2nd HD. for some reason my sustem won't detect it. Here's how I have it set up. Primary IDE Slot: HD #1 working fine Secondary IDE Slot: Master CD-ROM working fine Slave HD #2 not working any ideas would be appreciated. the first time i installed the 2nd HD it worked fine, so i shut down my computer so i could put it back together and when i booted back up it wasn't working. i've tried every combination i could think of as far as which drive was the master or slave and what not. they are different HDs, and i've read some HDs may not work with each other, dunno if that's the problem or not.
