Extend Drive

[Ron]

I have 2 36G drives in my server C: and its mirror. I
purchased 2 additional 36G drives and I now want to
extend C: and its mirror so that I end up with a 72G
drive that is mirrored. I've searched Google and the
Knowledge Base and they tell how to extend and how to
mirror but not how to do both. Could someone please shed
some light on this. Thanks in advance for youe help.

It is not possible to extend your system or boot volume, or any volume that
ever existed as a partition on a basic disk. Extending (software) mirrored
disks is not supported.

What you can do, is to mount your new mirrored disks as a folder in your
current C: volume, see this MS Knowledge Base article:

Thanks for your reply Bjorn. The reason that I wanted to
do this is because my SQL Server 2000 DB is getting very
large. If I set up my 2 new drives as D: and its mirror
and move my database to the D: drive, can I later on add
more drives and extend and mirror the D: drive since it
was never a basic disk and was formatted as dynamic?
Thanks in advance.

You can extend a simple or spanned volume, however not a mirrored volume or
a RAID-5 volume, when using software RAID. Most hardware RAID controllers
would allow this, though, even with basic disks, as long as it isn't your
system or boot volume/partition.
