i am not very familiar with raid partitons and am not even sure if this is the right place to ask about it, but i hope that if it is not that some one can point me on the right direction.
This is my situation, i have 2 500 GB hds and a 3ware pci-e hardware for raid and i wanted to make a RAID 1 but i dont know if i can make more then one partition for it, for instance:
MAIN HD: os partition: 100GB data partition: rest of left size
and make the RAID 1 either work on all the HD or just on the data partition of it.
that is on windows xp sp3 and the 3ware allows bootable raid.
Because you have a 3ware card, the RAID itself can be done at the hardware level. This needs to be done before you install windows on the system, through the BIOS of the RAID card itself (read the docs if you're unsure about how to get there, I think it's alt-3 during boot up)
Once you've created a RAID 1 on the two disks, your OS installs will only see a single 500 GB disk. You are then free to partition this as you like.
If you haven't already set up the RAID on the two disks, and you have already installed windows, I think your only resolution is to backup your data and reinstall.
Yes the RAID1 array will look like any disk to the system - so you can partition it any way you like.
