Hi all, I have OSX leopard as a disc image on my desktop. When I try to copy the .dmg file over to my external hard drive it copies for a while, then an error message says it can't copy it over and stops. I'm really confused as this sort of problem doesn't usually happen. I'm running Tiger 10.4.11 and I want to install Leopard. The Leopard disc image is 6.66GB. I can't burn it to a DVD either because the discs I have are 4.7GB & the .dmg is 6.66GB. Do I need to buy a bigger DVD blank disc? Another question is how I should burn the disc. Should I simply burn the .dmg file straight onto a DVD (if I can get one that is big enough!) using Disc Utility? THANK YOU VERY MUCH FOR TIME & HELP, I REALLY APPRECIATE IT!!!!!
