JClaney,
That's another case where you didn't give us all the information about your problem so we're left guessing and making WRONG assumptions.

Sorry about the wrong assumptions.
OK, so the new drive is SATA and the old drive is IDE.
NO problem, , , same answer.
First re-jumper the old drive to Slave and put it on the center connector on the IDE cable going to your DVD drive. Then make sure the DVD drive is jumpered to Master. (they usually come out of the factory set to "Cable Select") Usually that's the Right hand set of two pins in the jumper block, just to the left of the data cable.
Then boot up the system and the bios should see the old hard drive.
Unless the drive was also damaged when the old system gave up the ghost, it should now read.
Good Luck,
Shadow
