    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? Jan 26, 2010 at 14:19

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?

  • 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..

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.

  • no..how to scan it?
