Installing Leopard with 2 hdd

[modusph]

Hello,

I already installed leopard on my macbookpro and everything went all right, so , i would like to proceed with the installation on my mac pro, although, i have 2 disks in my mac pro, i dont have any other disk that i could use as backup disk, so, if i pass all my information (about 300gb), to my second hdd, and install leopard on the first disk, in the installation process of leopard os x, it would not format the second hdd ?

thank you very much

It won't touch the second hard disk unless you reformat it with Disk Utility. If you have you moved Applications or similar to the second disk with a symlink then you may find that it will update the files on that drive if you do Upgrade or Archive/Install, it may be a better idea to move stuff back first if possible.

If the second drive just contains things like you music/photo libraries or other data then it will be fine.
