    Hello, I have a 500GB WD Passport, 200GB partitioned for all my movies, etc, and 300GB partitioned for TM.

    I wanted to get rid of the TM partition. However, when I try to delete the partition, the minus arrow is greyed out, and on the side, it says 'this partition cannot be modified'.

    The only way to get rid of it is to delete my whole external HD, both partitions. However, I want to keep everything in partition 1.

    Any ideas? I've tried going to the TM partition and clicking erase.

    The simple answer is no. Disk Utility clearly tells you why.

    With GParted or other similar Linux partitioning tool, you will be able to delete, then shrink your partitions (but not grow), which might help you if you don't mind doing a lot of data shuffling.

    You may want to try iPartition. I haven't used this so I don't know if it's capable of resizing partitions on an MBR drive, but it might be worth downloading the demo to see if it's capable.
