My Vista computer is working fine – but I am having a slight problem with Acronis. If I inspect the drives using Disk Management in Control Panel, I can see both my internal hard drives , each being divided into two partitions. Disk O…. Appears as drives E: and F: Disk 1….Appears as drives C: and D: The critical thing is that my C: drive contains the OS and all programmes. Hence the computer knows that the OS is on Disk 1 and seems happy with it. Explorer lists the drives in alphabetical order no problem. The problem is with Acronis – I can take back-ups of the C: drive and can select the E: drive to store them. However, when I try to do a restore Acronis thinks that the OS and programmes are on the E: drive (presumably because it is on Disk 0). I therefore have to select the E: drive as the location to restore the OS and programmes and Acronis will happily write the restore to what is actually the C: drive. It is very confusing and is bound to lead to grief at some future time when I forget to transpose things. It seems to me that the answer is swap the identity of the hard drives so that C: is on Drive 0 – rather than Drive 1. What is the best way of getting drives C: and D: onto Disk 0 and drives E: and F: onto Disk 1 – hopefully without the need to reinstall Vista and programmes all over again. Is it as simple as swapping the drives physically in the tower – if so – will the computer boot OK or do I also have to fiddle with the BIOS. Or…is it possible to make a change in the BIOS that will fix the problem – if so – what and how.
