Hello, I just installed a new 320GB hard drive into one of my laptops - an Acer Aspire 5920G. I decided to install Linux Mint 8 onto it, downloaded onto a CD burnt from my mac. However when I looked at the "System Monitor" and went to "System" it said - "Available Disk Space: 0 bytes."

Would I be right in saying that the laptop doesn't recognise the drive? But if it didn't then Linux wouldn't have installed right? Any ideas?
