Recently I installed a second HD in a HP pavalion, Formated the new HD and sent it out the door. New HD was IDE1 slave. Customer calls from far away mad as Hell. His CDRom was not being seen by the system. He took it to a tech close to him and they had to remove the new HD.They called HP and was told the system could only see 2 Drives because of some propritary configuration. HP said if they would send the PC to them they could make the changes so it would see 4 drives and that the change could only be made by HP. Has anyone ran into this and is there a fix other than sending to HP. Seems kind of dumb to have 2 IDE channels limited to one drive each <IMG SRC="smilies/confused.gif" border="0"> <IMG SRC="smilies/confused.gif" border="0">
