I want to set apple capsule to backup my external hard drive, but it is currently in the exclusion list.
I can't remove it from the exclusion list, because I can't select it and the - option is greyed out.
It is a WD Passport, used for document files only.
Time Machine can't back up drives in some formats, such as FAT32.
The WD drive will need to be formatted in Mac OS Extended (Journaled) to be eligible for backups using Time Machine.
