Can't format SSD during installation

view full story

http://unix.stackexchange.com – Last night I tried to install Mandriva Linux on PC, where i have already Windows 7. In PC I've got 2 128GB SSD and 1 2TB hdd. On one SSD I installed Win7, and when I select the other empty SSD for installation, I couldn't format it. I get this message: ext4 formatting of sdb1 failed I don't remember what version on linux I tried to install. Is where a problem to have 2 os on 2 different hard drives, and have option to choose which os i want to run? How should I format empty ssd to install linux on it? (HowTos)
