Stupid question we forgot to ask. Do you have the master/slave jumpers on the back of the HD's set the right positions?
The old drive should be set to slave and the one already in the computer should be set to master.
And does the old drive have windows installed on it? If it does there may be a conflict. Windows does not like 2 system disks installed at teh same time.
