Run ScanDisk on the drive.
Shut down the computer
before inserting removing a
hard drive.
Completely turn off the
computer. Turn the
computer back on, then
run Computer Setup by
pressing F10 when the

Solution
Install the appropriate software on
the second device, start the second
device, and start the program on
both computers.
Your Compaq computer uses the IrDA
communications protocol.
Communication between infrared
devices must use the same
communications protocol. Check the
manufacturer's instructions for
connecting with infrared devices or
try connecting with a device you
know to be IrDA-compliant.
Remove the obstruction, align the
infrared ports to within 30 degrees,
and position computers within 1.5
feet (about 0.5 meter) of each other.
Check for IRQ conflicts in the Device
Manager. If two devices have the
same IRQ address, reassign one of
the devices.
Select the same baud rate for both
computers.
Select the same # bits setting for
both computers.
Select the same stop byte for both
computers.
