I recently purchased the Intel X25-M 160GB SSD to replace the generic 240GB harddrive that came with my 13" MacBook Pro. What I tried to do is copy the entire harddrive to the SSD via the disk utility "Restore" function. I restarted and booted from the installation CD so the main drive would not be in use. The SSD is connected via USB. Unfortunately when I try to copy the content over, I get an error message that the SSD does not have enough space available. I find that odd because I am only using 104GB of the 240GB Harddrive and the SSD has 160GB available. Am I doing something wrong here? It seemed to work when I did the exact same thing i.e. with the disk utility from within the OS... but because it said something with 6 hours duration, I though it might be faster if it was done without the main drive in use. Any suggestions?
