I added a new hard drive to a P3-1000, I cloned the new drive. It is a 7200 RPM 133mHz drive that needs the accelerator card to get the 133mHz speed. Now the new drive will boot without the accelerator card, and is somewhat faster than the original drive, but it won’t boot on the accelerator card. Device driver states the Card is working normally. I tried everything I could think of. The only thing I didn’t do is a fresh install of the operating system with the new drive on the card. The owner doesn’t know where his software is. (They want a computer, but like others, they don’t take having a computer serious enough to really “get into it”). Not doing a “fresh install”, do you suspect that is the main problem or is there any suggestions. Of course I checked the Master, Slave, settings on the hard drive and then changed them to suit after cloning. To clone, I used Acronis True Image 10. I am stumped.
