I have external drive to which I have installed ubuntu and its running fine. I want to test a distro -- Mandrake 10.1 CE. Now i want to install it to this drive but I cant do it. The problem is known though. I have to add USB modules and sleep command to the loader. DOing this i have to rebuild initrd to usbinit bt while doing this I get error "There is no space left on the drive".

Secondly, will i be able to share my partitions?

Thanks in advance
