TrueImage can image completely w/o having to boot out of XP, is very fast,
can image and restore over a network, latest version does scheduled full and
incremental backups and drive cloning. A recent restore of 90 or so gig of
data took about 1 hr. and 15 minutes.
I owned Drive Image 2002 and used it successfully on Win ME for a month or
so to do unattended backups (after a HD failure). Upgraded to XP, then could
not get DI it to work through Windows-- continual "out of memory" errors on
reboot. NO useful info on PQ Tech Support website for XP or running through
Windows, emails to Tech Support came back with "canned" responses pointing
me to older solutions on website for problems booting from floppy disks.
This prompted me to change to TrueImage about a year and a half ago. I did
have one initial problem with TrueImage-- could not boot from its boot CD
with my Compaq USB keyboard attached (ok with a PS2 keyboard). Acronis tech
support worked me through the problem, and the latest version (7.00) appears
to have resolved this issue.
There is a review of the 6.0 version at

I can't comment on Ghost-- never tried it.
