How do I install another hard drive. I installed it but it does not show up in 'My Computer' I know there is another step but I cannot remember. Please help. Thanks in advance.

The harddisk will need to be PARTITIONED and FORMATTED. the New way: Start > RUN > diskmgmt.msc Make a new Partition the the empty drive, format to NTFS. The old way: Make a boot disk using Format a: /s after putting a floppy disk in your drive and use it to boot the computer. When in the prompt type "FDISK" and press enter. Use the program to PARTITION the harddrive to FAT32. Next reboot the computer (still using the floppy) then FORMAT the new harddrive. For help with the format command use format /? but i think the command you need is format /U. This will take some time. When you are done, remove the disk and boot up as normal. Convert the Drive to NTFS.

You installed it? Did you make sure your system could interface with this device - (DMA33/ATA 33,66,100)? Have you selected it to be a primary slave or secondary master (IDE), or sequenced and terminated it (SCSI)? Have you connected the cables correctly? Have you confirmed that your BIOS is aware of it? Is the appropriate hardware controller enabled in the BIOS, or adaptor card installed in Windows? Is a driver installed for that controller? ...So you did install it? Please go to step one above.
