    try resetting all that can be reseted...like..
    - unplug all usb's and any other peripheral device, take out battery and wait 10-15 mins
    - while mac is off, press simultaneously ctrl+alt+AppleKey+PowerButton 3-4 times
    turn the mac on
    - after boot sound hold AppleKey+Alt+P+R
    - after boot sound hold AppleKey+Alt+O+F and when you go to OpenFirmware type:
    1)reset-nvram (hit enter key)
    2)set-defaults (hit enter key)
    3)reset-all (hit enter key) (mac will restart)

    - try connecting the harddrive now...

    i ended up figuring out that the usb cable i was using was the problem.. the head that plugs into the drive was bent and must have not been a good connection..

    thanks guys
