A friend of mine has a Macbook Pro, and an older 80GB external hard drive.
She is copying files from the external hard drive (which contains all her work) to the Macbook, but slowly because she's reorganizing the data at the same time.
I would like her to back up the external hard drive onto the Macbook, which has 750 Gigabytes of space, just in case something happens to the external drive.
Is there a quick, easy, preferably built-in way to do this? I would prefer a method that doesn't copy files separately (so as not to create a second location on the machine that contains all her work, gets indexed, etc.) but takes a disk image and stores it somewhere. The goal is just to have a quick snapshot in case anything goes wrong.
