thats to do with partitions what operating system are you using
if you are using 9x follow this you will need a boot disk and beware THIS WILL WIPE EVERYTHING ON YOUR HARD DISK DRIVE SO MAKE SURE YOU HAVE A OPERATING SYSTEM SETUP DISK WITH PRODUCT KEY HANDY
Firstly go into the bios and set the floppy disk to boot first
Insert a DOS/Windows bootable floppy disk into the floppy disk drive. Reset the computer and allow it to boot up to a DOS prompt.
then using the keyboared navigate to the START COMPUTER WITHOUOT CD-ROM SUPPORT tab and press enter
The computer should be displaying the prompt "A:". This means that the computer is looking at the A drive, that is the floppy disk.
Type the command "FDISK" and press enter. Let me again warn you that this innocuous looking program is very powerful and will destroy any information previously held on the hard drive. Be very care what you do with this program.
this may now ask you if you want to enable large disk support type Y and press enter
when the menu comes up choose option 3 (The Delete DOS Partition Or Logical DOS Drive)
press 1 and press enter then the drive information shall be displayed press 1 and press enter you now may need to press enter again (it may warn you that all data will be lost)
Enter the Volume Label
for the partition as displayed on the table (just press ENTER if the label is blank).
Confirm the choice when asked "Are you sure?" by pressing Y and ENTER.
Press ESC to return to the main menu
At the main menu choose option 1. The "Create DOS Partition" screen will then be displayed
Choose option 1 "Create Primary DOS Partition". Fdisk will verify the hard drives integrity and ask if you want to use the maximum avalible size for a primary dos partiton press Y and then enter
The computer will verify the hard disk integrity again. On completion press ESC to exit each FDISK menu and return to the A:\> prompt.
Power off the computer.
the computer is now ready to be formated
hope i have been of help
