    Hello all, I have an external hard drive with lots of material from my last macbook on it that I do not currently have ob my macbook pro.

    I wasn't to run a full backup to my External HD, but if I try to use Time Machine it tell she I need to erase the Hard Drive in order to back the laptop up to the Hard Drive.

    Is there anyway around this without having to erase the disk?

    Time Machine requires the disk to be formatted as HFS+ Extended (Journaled) and that the partition type is GUID Partition Table (GPT).

    Unfortunately no, it needs to be formatted first. I had the same issue a few years ago.

    I figured as much.

    Is there anyway around it without using time machine?

    Use a tool like SuperDuper or Carbon Copy Cloner? I haven't used either for a while but I'd think they or some other similar alternative would do the trick.

    I am just going to end up transferring everything, deleting it and reformatting for time machine I guess. None of them work with my format file. I appreciate the information and help!

    If it is already guild partion scheme you can make separate partitions through disk utility and keep your old data on one partition and format the other to work with time machine.
