A few months ago I decided to format an external HD that I wish to use with my Mac mini, but I can not use 100% of it.
In the formatting process, a partition called EFI appeared. When I open the Disk Utility app, the partition is not displayed, but it was displayed by the command line using
Here is the Disk Utility:
From the command line:
/dev/disk0 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_HFS MAC HD 881.0 GB disk0s2 3: Microsoft Reserved 16.8 MB disk0s3 4: Microsoft Basic Data BOOTCAMP 118.9 GB disk0s4 /dev/disk1 (external, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *640.1 GB disk1 1: EFI EFI 209.7 MB disk1s1 2: Microsoft Basic Data HD Caio 639.9 GB disk1s2
How can I recover the space lost to disk1s1?
