I put the known working HDD which is a Hitachi Travelstar 30 gb 4200 rpm in the computer Compaq nc6120. What came up was "163 time and date not set", then "a disk read error occured. Press ctrl+Alt+del to restart (which does nothing). The HDD that came out of that computer is a Seagate 40 gb 5400 rpm. When I put that in the other computer (compaq nx9020) it flashes operating system not found several times, then just blank. Are the 4200 & 5400 interchangable? Google search was no help. Any one have any ideas? Thanks for any help.
"163 time and date not set", then "a disk read error occured."
Sounds like the CMOS battery is either on its' way out or you may have just disconnected it long enough to lose the settings. Either way, you'll likely have to run the BIOS setup again to get the machine working.
