Adding additional internal hard drive

[greenmamba11]

Hello, I am a Mac Newbie. I got an excellent deal on this one and although it is old, I LOVE IT. I purchased an additional hard drive last night. I have searched and read as many post as I could find before asking. I have done everything that was suggested to do regarding installing another hard drive. I do not have an additional controller card but I thought that I read somewhere in post that I would need a card if the hard drives were to exceed 128GB. I have existing 80G 7200 rpm and bought a IDE 120GB (model WD1200JB00CRA1). I tried it first by just adding it to the back and it would not power up because I had the cabling where it was seen first and the existing drive set to cable select and I did not put any jumpers on the new one. Next, I tried making it slave, then tried making it also cable select with the original one being seen first. Still will not power up but at least it gets to the screen with the apple on it. I think it may be because it is a slower drive or is it because I have to have an additional controller card?

You have two options on how to set up new hard drives:

1) Use a master/slave jumper setting on the drives
2) Use the cable select jumper setting on the drives

You cannot mix and match between the two: if one drive is jumpered as "cable select," then the other drive must also be set to "cable select."

Likewise, if one drive is set to "master," then the other drive must be set to "slave" (and vice-versa).

You cannot jumper one drive as "slave" (or master) and jumper the other as "cable select."

Depending on what kind of Mac you have, you will either need to jumper the original drive as "master" and the new drive as "slave" (in the case where they're both on the SAME ribbon cable), or jumper both drives as "cable select."

If the drives are on separate ribbon cables, then you will either jumper BOTH drives as "master" or BOTH drives as "cable select."

Please post back with the exact model of Macintosh you have, and the exact jumper settings you're using.
