Screw the drive into the case (Try avoiding magnetic screwdrivers with HDD's, tends to dislike them.)
Plug the ribbon cable into the primary (IDE 1) channel on the motherboard and into the drive, make sure the jumper on the drive is set to "Cable Select". WD drives like this setting...
Plug the power cable in, then set up the rest of the computer.
Before you can use the drive, it needs to be partitioned and formatted.....
Partitioning.
Get a floppy disk and format it as a system disk. You can use any computer running Windows 95/98/ME to do this.
Put this disk into the new computer, start it up, and type "FDISK" at the prompt.
In the menu, select the disk drive, and "create a partition".
Once you have made a partition, restart the computer with the floppy disk in again.
Now it's partitioned, now:
Formatting.
In the DOS prompt type, without the speech marks:
"C:"
"Format c:"
(then answer yes).
There is your new drive
After that you can use it, but I would run SCANDISK (at the prompt) to check the drive is ok.
Once XP is installed, you can change the drive system to NTFS (it's the file system that XP prefers, you can change it to NTFS from the original without losing data.
The system used in FDISK is FAT32, it's what Windows 95, 98, and ME use. XP can use FAT32 partitions, but Microsoft advise using NTFS. If you want to convert the partition to NTFS, there is a utility called "Drive Converter" in XP.
You don't have to convert it.
if i have a xp home edition upgrade i have heard that if i put that in it will ask me for a original os so i just put any in there
98,2000,me,nt? and just keep conyinue with the instal?????
You will need to install Windows 98 (maybe Windows 95 or NT is ok), ME or 2000 to upgrade it to XP.
Good luck.
