OK -- I've read dozens of questions/answers on this topic in various forums now and NONE of them has answered my own question! Specifically, I need to know how to unpartition an older 10GB "LaCie" external drive, which I gave to my daughter, along with my old Mac G3, running OSX 3.0. When I go to "Disk Utility" (even on my Mac here at home, running OSX 4.11) I CANNOT locate ANYTHING about "partitions" or "reformatting." All that's there is the standard: First Aid, Erase, RAID, and Restore. I've had her erase the separate partitions, but all that does is eliminate the data -- the 3 partitions are still intact. HOW DO WE COMBINE THEM, so that the external hard-drive is just ONE volume? So far, I've not seen anyone else ask this specific question, and I don't see an answer for this anywhere either. PLEASE HELP! It's totally unnecessary to have a small 10GB hard-drive partitioned into three volumes. . . but when the drive was new, 10GB was ENORMOUS to me! BTW -- I also rebooted my own computer this morning and started-up from the system-install disk -- couldn't locate anything on that either for reformatting/partitioning/unpartitioning drives. WHERE IS THIS INFO? Feeling very dense -- just can't locate the solution for this -- and it seems it should be so simple! Thanks in advance for any help you can give me.
