They both have "the same #?" Do you mean that when you run Ghost, it
identifies both of them as "Drive 0" or both as "Drive 1?"
Or do you mean that the number representing their size is the same?
Your MB doesn't perchance have the capability of installing these two
drives as a RAID 1 array, does it? It really sounds like you might be
better off with a mirrored RAID setup. If you want to do it by
cloning, though, the only reliable way is to clone it every day, and
that's kind of a pain.
Another way, although not free, is by IMAGING your C: drive onto the
other drive rather than CLONING it. For this, you could use Ghost or
Drive Image, but there are two much better solutions, and both run
from within Windows. These are PowerQuest's (now Symantec's) V2i
Protector Desktop (about $70, XP and 2000 only) and Acronis True Image
7 (about $50 and I think it runs in all versions of Windows). They
are similar to Ghost and Drive Image, but (and this is a big "but")
they can make INCREMENTAL backups. You just make a baseline image,
and the software will make one or more incremental backups each day in
the background without user intervention. Then if you ever have to
restore, you just boot from the V2i or True Image CD and restore from
the images. The only data you would lose would be any that was
written after the last incremental backup. This method is both better
and easier than repeated cloning of the C: drive. This method also
has the advantage of COMPRESSION so that you can easily fit the backup
of the first drive onto the identically-sized second drive, even if
the first drive is nearly full.
