Re: Hard drive question
Also, many BIOSs auto-detect hardware and update accordingly. If you booted the computer without the drive, it might have removed it from its hardware list. Then what might have happened is when you booted with it plugged back in, the BIOS finished loading before the drive was spinning at full speed and ready to be recognized. The solution: boot the computer and restart without turning off. If restart isn't an option, just turn it off and back on as fast as you can so as to keep the hard drive spinning as fast as possible to make sure it is ready for when the BIOS scans the hardware again.
