I recently needed to increase the size of boot (C drive (from 80Gb to 300Gb). I originally had two SATA drives in my PC, an 80 GB (C drive that contained WinXP and a secondary 160 GB (G drive that I was using for data storage. So what I did was to remove the 160 GB drive and install the 300 GB drive in its place, then cloned (using Acronis Disk Image 8.0) my 80 GB drive to the 300 GB drive. Then I replaced the 80 GB drive with the 300 GB drive, and re-installed the 160 GB drive, booted up and everything was good until I went to look for the 160 GB drive in My Computer and it wasn’t there. I looked into the Device Manager and both drives show up fine. All three drives are Seagate SATA, with nothing on the jumper pins (which I think means their using cable select?), and I believe when I was in Device Manager the 300 GB drive was showing up in Location 0, and the 160 GB drive was showing up in Location 1 and the status on both devices was “This device is working properly”. I then re-installed the original 80 GB drive and the 160 showed up again. Can someone please tell me what I need to do to be able to see the 160 drive when the 300 GB drive swapped in again? Thanks!
