I have two 80GB hard drives, and I use Symantec's Ghost to clone the C drive on the D drive. The two drives are "cable select." Both drives are recognized and "Primary" and "Active". The operating system is XP Home. Ghost enables you to make boot disks, which I have done, which enable you to run Ghost in PC Dos in the event of a failure which prevents you from booting to Windows. There are two failure scenarios I want to consider: 1) In the event of a "corruption" problem on the C drive, I plan re-partition and/or re-format the C, and clone the D back to the C, using Ghost in PC DOS mode. 2) In the event of a "catastrophic" failure to the C drive, I plan to physically switch the two hard drives, making the D the C, and the C the D, expecting that I could then start-up and boot directly into Windows. Are there any problems in my doing either of the above procedures? For example: Does Ghost clone all the boot and start sequence in the root of the C drive, so that putting the D drive in the C position would enable me to boot directly to Windows? I appreciate any help anyone can provide. This drive setup configuration is my backup scheme, so if it doesn't work, I'll be in deep vanilla yogurt if something goes wrong with the C drive.
