What are you backing up to? External USB hard drive, network hard
drive or similar?
At the moment it has 2 x 300GB drives which I believe are operating as a
RAID. I guess that would be RAID 0 as they present themselves as one
logical
drive partition of about 600GB. It's running under XP Pro buy the way, in
case that makes any difference.
It shows that the RAID0 (or possibly JBOD) is being managed by your
hardware, at least. Which is good news, since it means Acronis won't
have any trouble imaging it off. As far as any software is concerned,
there really is just one 600gig disk there.
You can check in the BIOS, or possibly the BIOS of the RAID chip, to
see what's actually set up.
I'm nervous about using Acronis with a RAID so would like to format both
disks, but with several partitions such that I have one partition for
Windows OS and progs, another for data and then others (3 at least ) for a
dual boot to Linux. Hopefully there's a way to do this so that I can use
both drives flexibly (as if they were one) and also in a way such that
Acronis back-up won't fall over.
You're better off not sticking with the existing RAID0 setup. It gives
you twice the chance of losing everything, since either disk could
pop. Personally, I'd pop out and buy a 750gig drive.
But you can go ahead if you like. Image off the data using Acronis,
then use Acronis to repartition, then restore the C: and data as you
wish.
But: Acronis backups are most useful when you're intending to restore
the whole lot onto the same partition setup. If you were intending to
take the opportunity to reinstall a clean Windows, then you might as
well just copy your data off to the external backup drive instead of
creating an Acronis image of it. In fact, I don't think you can tell
Acronis to *not* restore that 400gig of data from a C: image onto the
new smaller C: but put it on the new D: instead.
Note that you can only have four partitions on a disk, but if you make
one an extended partition you can subpartition that as many times as
you like.

Okay, now found how to get into the RAID BIOS so now I think I know how to
set it all up again after a reformat or fitting a larger disk. Time will
tell!
I meant to ask about the fact you say you can only have 4 partitions on a
disk. Am I right in thinking this doesn't mean 8 partitions across two
disks if RAID 0.
I am running another PC with XP on one partiton and a dual boot linux across
4 others...or so I thought. All this on just one disk. So does this mean the
4 partition limit is only valid for each boot sequence?
Thanks again for your time.
