Disk Management Question re converting to dynamic disks


K

Ken Gardner

I have two physical hard drives on my computer. Both are approximately 238
GB. I am using them as a RAID 0 array (i.e. striped). Both are basic disks
with a single primary partition on each drive.

Here is my question. Can I convert both drives to dynamic disks and then
combine them (so that I get one 465 GB dynamic drive) without disrupting the
performance gains from the RAID 0 array? If I do this, will I take a
performance hit on the HD?

TIA,
Ken

All in all, it's a bad deal! You'd not only lose the benefits of the RAID-0
performance, but you'd get a performance penalty from the spanned drive
overhead.

If those are the only 2 drives on your machine, you'd also have the problem
that dynamic drives which contain the system partition or the boot partition,
cannot be spanned.

It turns out that I cannot do it anyway. Disk Management simply doesn't
give me the option of converting to dynamic disks. I am virtually 100%
certain that this has to do with pre-existing RAID-0 array. I guess that I
can wipe both drives, undo the RAID thingie, reinstall everything, convert
the disks to dynamic....nah, I think my sock drawer needs much more urgent
attention. :)

Thanks

Ken,

I'm not sure I fully understand your situation and the thing that confuses
me most is this: Dynamic disks is basically software RAID technology so why
move to software RAID if you have hardware RAID already?..

And if you already have two 200 GB disks in RAID 0 configuration, operating
system should see it as a single 400 GB volume so I'm not sure what are you
talking about here.

That's an excellent question. Here's the answer. When an Intel program
created the RAID 0 array, it did so in two partitions of 238 GB each (C
drive and D drive). I would like to know if I can change this so that the
system sees one C partition of 465 GB.
And if you already have two 200 GB disks in RAID 0 configuration,
operating system should see it as a single 400 GB volume so I'm not sure
what are you talking about here.

On Disk Manager, the two physical drives show up as Disk 0 with two
partitions. These are basic disks. Can you extend the partition of a basic
disk in Vista? If so, I might solve my problem by deleting the D partition
and then extending the C partition.

I just answered my own question. Yes I can! Vista is way cool.

Well, I have you to thank for it. :). When you suggested that my setup was
a hardware version of dynamic disks so why mess with it, the solution
presented itself. It took me all of 3 minutes.
