Thanks, Dean. Problem now in Disk Utility is to select a disk (drive) where "Partition" shows and Volume Scheme and Volume Information boxes are not greyed out. After sitting awhile another entry appears below Macintosh HD and my optical drive: Bob McDaniel's MacBook Pro, and indented below, time capsule backups. I sure don't want to erase the backups! It also says that the currently selected disk (200.05 GB FUJITSU MMY 22) is the start-up disk and it cannot be erased. BTW when I select "Macintosh HD" the "Partition" button does not appear.
