During POST (Power On Self Test), the BIOS try to get information about all the devises
Connected to the system. After checking the processor and RAM it checks for devise such you're hard disk, CD-ROM, etc., and display them on screen with messages such
As 'detecting IDE drives.' and Found Primary Master..'etc. Sometimes your BIOS
Just refuses to recognize your hard disk, basically making it useless-there's no way windows will recognize your hard disk if the BIOS doesn't. Let's see why this happens:
Laptop Battery The most common reason is a loose or badly connected data cable. Make sure the data cable is plugged in properly, both into the hard disk, as well as the motherboard. The same goes for power cable, so check that as well. Also, make sure that the red lines on the data cable and power cable are adjacent to each other.
On startup, Linux uses a small program, usually one called LILO (for Linux Loader), to get everything going. LILO works through your computer's BIOS. Until just a couple of years ago, based computers couldn't recognize hard disks larger than 1, 024 cylinders, which works out to about 6 Gb. Of course, once the operating system was booted up and running, it could support much larger hard disks, but the BIOS couldn't. You didn't need to put all of Linux in that first 6 Gb, just LILO.
Thinkpad One you've ruled out any cable problems, check the jumper setting on the drives. If two drives are connected to a port, make sure one is set as master and the other as Slave, or else both are set to Cable Select.
Quite often problems arise with hard disk drives that cannot be solved without a technically advanced disk editor. back up, copying, or recovery of boot sectors and other important data areas of a hard drive; or extraction of information that was removed by accident or lost due to failures, or through the destruction from an erroneous computer virus. For these and a host of other problems, the Acronis Disk Editor software solves and repairs issues associated with hard disk drives.
Microsoft Next, make sure your drive controllers on your motherboard are not disabled. These controllers control IDE devices, and without them the BIOS cannot detect the drives. Go to the BIOS setup, and under the Integrated Peripherals menu, make sure that 'On Board HDC' is enabled for both Primary and Secondary channels. Also ensure that all drive types are set to AUTO under the Standard CMOS Setting. If you are not comfortable with changing the BIOS values, just reset the BIOS to factory defaults.
Centennial School District in suburban Philadelphia, which educates 6, 12, critical servers that were running out of hard disk space within the server partitions. The district licensed Acronis Disk Server 10.0 to repartition the hard drives on its five production servers quickly and easily. As a result, the servers are no longer at risk of crashing due to hard disk space issues. The server reconfiguration was completed quickly, of rebuilding the servers from scratch.
