I have added a second hard drive .I just plugged it in and XP recognized it but it does not show when I click on "explore".I can't figure out how to use it.Any tips on adding and using a second hard drive or slave would be greatly appreciated.
You need to format it. Right-click on My Computer and click Manage. Click on Disk Management, Find your new drive, right click and select create partition. Once its done, right click and create a logical drive.
