A 'backup' of your internal IDE drive, made with Ghost or Drive image will be
a single compressed file. It is impossible to use this as a bootable drive
for that very reason.

One uses Ghost or the like to create a backup from which the C Drive can be
recreated using a restore process.

Should you find that you have corrupted your internal drive, then you would
use the bootable floopy disk set made by Ghost in order to load up a DOS
environment and restore from the external drive.

Should you wish to clone your C Drive then you should carefully read the
instructions for this process. In order for you to be able to take a cloned
drive out of the USB enclosure and install it into the PC [replacing a failed
C Drive] you should also make sure that it is an identical unit to the C
drive [make, model, size]. If it isn't identical, Windows' anti piracy
features will prevent the system from booting and you will need to perform a
repair installation of XP before attempting to boot from that drive.

Similarly, if you use it for the purposes of backup, then when it restores
to a new Hard Drive, it must be to an identical unit to the C drive [make,
model, size], if the original C drive has failed.

Prior to using any new hard drive in the pC it must first be initialised and
then formatted: you'll need to perform this in a workling XP system or from
an XP installation CD or using a third party disk management utility. Such
utilities are supplied free with new Retail packaged disks from most
manufacturers including Maxtor and Seagate.
