    2hd on 1 IDE cable

    Okay, I have a question. I just added a second harddrive to my computer. The way I have it setup is, 2 cd drives on IDE2 and 2 harddrives on IDE1. My system seems to be booting up kinda slow and I herd usally its best to have the 2 cd drives on diffrent IDE cables I was wondering if I had 1hd and 1cd drive on IDE1 and the other on IDE2 would my system boot faster?? thanks

    1. Make sure that you've jumpered the booting HD as "Master" and the other drive on the cable as "Slave" and you've attached the master and slave drives to the appropirate connections on the cable. Don't remember if the master goes at the end or the slave goes at the end of the cable. In the "old days" (windows 3.11), both drives had to be the same size (cylinders and heads). On a Win95 (upgraded later to Win98) desktop, I had a 40GB master and a 2.5GB slave on the same cable with NO troubles, but they were from the same manufacturer.

    2. If you also changed your O/S to WinXP, you'll find that it boots much slower, because it is larger. There are some excellent books on how to speed up the XP boot and reduce its O/S-memory useage.

    3. Make sure you also jumper your CD drives as "Master" and "slave" and attach them appropriately to the cable. Again, I don't remember if the master goes at the end or the slave goes at the end of the cable. You may find it easier to assign the second CD as a "detatchable temporary device" using your USB port.

    I hope this helps, but I have to make a few corrections to the previous post. Please don't get mad at me.

    1) It doesn't matter which end of the cable the master is on for IDE drives.
    2) If the jumpers were conflicting (IE both set as master) it would not boot at all. However, as stated by vududoc you do want the boot drive as master.
    3) Yes, sometimes having both cd drives on the same channel can cause problems, but unless that is the problem you want the cd's separate from the hd's. The reason is, with IDE the channel is only as fast as the slowest drive, so the cd's will lower the transfer rate of the hd's if you have a cd drive paired with the hd. As an example I have 2 hd's on my primary channel (120gb and 80 gb) and a dvd-rom and a dvd-rw on the secondary channel.
    4) If the newer drive is a newer standard than your IDE controller that can cause issues. Such as if your controller and/or IDE cable is only an ATA-66 and the new drive is a ATA-133.

    Also, if the OS is on the slave drive it will boot slower because it will be looking for the OS on the master first. It may also check the floppy and/or the cd drives before the other hard drive. It depends on how the boot sequence is setup in the BIOS.

    Finally, vududoc, could you explain what you mean by "You may find it easier to assign the second CD as a "detatchable temporary device" using your USB port." I have no clue what you mean there. Thanks, hope this helps.
