The problem you have may be in the computer or Disk II. If you have
another Apple II, trying the drive and card in it would help isolate
the problem. If not then more information would be usefull.

1) does the computers power light come on at power up.
2) Do you get a beep at power up
3) which Apple II do you have II, II+, IIe, IIgs?
4) if you pull the Disk II card and power up do you get a beep and
    a ] or > cursor?
5) do you have two Disk II drives
