Disk drive overlay (DDO) or other software utility
The computer's hard drive may be utilizing a DDO (Disk Drive Overlay), which is commonly used for larger hard drives to allow them to work properly. When using a DDO you must boot the computer from the hard drive as normal. As the computer is booting up you should see a message asking you to press a key such as Ctrl + Esc to boot from a floppy. Once the key combination is pressed for your DDO, you will then have the opportunity to place the disk within the computer and boot from the disk, and at the same time be able to read from the hard drive.
Hard drive is a SCSI hard drive
If you are using a SCSI hard drive it may not be able to be seen unless the SCSI device drivers are being loaded for it. In addition, some manufacturers may require the drive to be setup and created through the SCSI utility and not Fdisk.
See the SCSI help and support page for further information and help.
Hard drive is not properly setup in CMOS
If the computer hard drive is not setup properly in CMOS Setup, the hard drive will not be recognized properly. Verify that CMOS is properly detecting and initializing the hard drive.
Hard drive is bad, not formatted
When attempting to type fdisk you receive a message saying "No Fixed Disks preset", then this could be a bad hard drive or possibly loose connections. If you are able to get into the FDISK options, delete, and then recreate the partition (This will erase all the information on the hard drive). Also, after this is done format the partition to allow it to be readable.
