I have an external hard drive with two partitions. Both use HFS+ (Mac file system) and I want to join them into one without losing the data on one of the partitions. I'd make a backup on the computer, format the external into one partition but the internal hard drive does not have enough free space. The only solution I have found so far is creating an image of the content. Hopefully the compression will fit to my local hard drive? If you have a better solution please share? thanks!
