I have a 3TB My Book and need to have a single partition using as much of the 3TB as possible. The drive has two partitions, 2048 on the left and 746.49 on the right. When I try to extend the left hand partition into unallocated right hand one, “extend partition” is grayed out. I can format the right side but can not do anything with the left.
I have no problem with losing any data on the drive so I can reformat the entire drive if someone would explain how this is done. When I try to do this, it only formats the left hand partition.
Thanks for any help.
