Was the hard drive detected by your BIOS? Maybe windows/linux just didn't mount it automatically? I need some more information, what operating system are you using? – Jeffrey Vandenborne Jan 26 '10 at 14:19

Please add this info to your question :) – Ivo Flipse Jan 27 '10 at 11:09

It probably needs to be formatted.

  1. Right-click on My Computer and select manage
  2. Expand out Storage on the left and click on "Disk Management"
  3. You should see your new disk located in the bottom-middle pane, probably labled "Disk 1"
  4. Right-click your unformatted disk and follow the prompts through the wizard to format it correctly.

my extra hard disk have only 1 jumper and no pins allowed for the slave..only for master and cable select..can i use it as a master? – Paul Jan 27 '10 at 10:28
i open disk management but only disk 0 is in there – Paul Jan 27 '10 at 11:02
my primary hard disk was hook on the middle and the cd drive was hook on the end of the IDE. i unplug the IDE on the cd drive and i replace it with my extra hard disk. but my extra hard disk was label No Jumper=DS(SLAVE) so i use it as a master and i set my primary hard disk as a slave.. – Paul Jan 28 '10 at 12:57

Can you see the extra hard disk at the hard drives in Device manager? if yes,then it needs to be formatted.if not simply detect it manually or scan it.
