Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Making a backup of your Windows partition is probably not a bad idea before playing around, but I don't see a problem with using mdadm to create raid partitions on the remaining free space on the drives.
I think you are absolutely right to be concerned. I would never try to use one RAID array with two different RAID software packages. Keep one RAID software for the array. Buy new disks for a Linux RAID array.
Or get a hardware RAID card. Then you wouldn't need to use the software RAID on the operating systems. That would be the only way that I would share a RAID array between two different operating systems.

In order to access the data on your array you'll need to run dmraid. Do a search here on LQ and you'll probably find several posts from me and others on how to use it. I use dmraid to dual boot Windows and Linux on my test machine on a really old FastTrak66 FakeRaid card. It seems to work just fine.
Thanks a lot for the info. I have managed to mount my 1.4TB NTFS Raid1 under Linux with no effort.
I am using Ubuntu 7.04 which is truly the first Linux that I can give to anybody to install and be sure that they'll be able to do a lot more than with Windows!
I simply did an: root@ubuntu:/mnt# apt-get install dmraid
The install autodetected some stuff, shortly after:
root@ubuntu:/mnt# ls /dev/mapper
control sil_agajdfbicfab sil_agajdfbicfab1 root@ubuntu:/mnt# mkdir /media/RAID root@ubuntu:/mnt# mount /dev/mapper/sil_agajdfbicfab1 /media/RAID
And Whalla... my RAID is visible from Linux. From here it's trivial to add an entry to /etc/fstab, or probably use some built-in Ubuntu tool I have yet to come across, to make sure the drive mounts automatically when I need it.
PS "dmraid -a y" is the correct command, but as I said, Ubuntu ran this automatically.
