Hello everyone, I'm trying to install Snow Leopard (yep... cause I have a 2008 MBP) through a USB flash drive. My flash drive is 8 GB (but in reality 7 GB) and the DMG image is 6.2 GB. With "Disk Utility" I have erased the flash memory with "Mac OS extended (Journaled)" file system. Then I wen on the "Restore" tab, I set the DMG image as source, and the flash memory partition as destination, then I checked the box "Erase destination". Then I clicked on "Restore" and it gave me this message: "Restore error - Not enough space on /dev/disk1s2 for the restore". (The messages I write here could not be the exact strings as I'm not using the OS in English, I just translated them) Why not enough space??? The DMG image is 6.2 GB and the flash memory is 7 GB!!! If instead I un-check the "Erase destination" it says: "Restore error - Operation not supported by the device". Instead of erasing the USB drive, I also tried to partition it, with "Mac OS extended (Journaled)" file system, and with GUID partition table, but the same thing happends. I've also tried to do "Analyse image for the restore" but it's useless. I hope someone could help me to find a solution, otherwise I have wasted money to buy a 8 GB flash drive... Thanks everyone.
