hey i have my computer all set up but... its been a while and my computer.......
says...after its all to gether....
!!!!!!!!!!!!!!!!!IDE DRIVERS INSTALLATION ERROR!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
FOR BEST PERFORMANCE,PLSE CHANGE THE STAND ALONE DRIVE TO MASTER.SYSTEM HALT....
On the back of your hard drive there are pins ( you don't plug a cable into these pins) but there is a little sleeve type thing that you can take off and place on different pins. It should cover two pins at a time. There should also be a diagram in your hard drive manual or right above the pins that tells you how to set that sleeve so that your hard drive is set to master.
I beleive there are a couple different settings... Cable Select, Master, Slave.
It seems like yours is set to slave, the reasoning they have these it for people with multiple hard drives.
Here is a step my step process for this
