USB does not appear to be whole

[timguy36]

Try again with UniBeast 8.1 released today.

Just finished trying UniBeast 8.1, the same error came up, "copy of afps.efi failed"

 

[MacMan]

OK, "copy of afps.efi failed" is different from your original error.

In Terminal run the following command with the USB stick mounted:

diskutil list

This is after running UniBeast and getting the error.

Just had the same problem with a newly purchased 32GB SanDisk Ultra Fit, except the error message was "
/dev/disk2s1 does not appear to be a whole disk". This is on a MacBook Pro with a fresh 10.13.1 install.

My solution was to format the USB drive using a patched version of Disk Utility (v.13) on my El Capitan hackintosh, selecting GPT in the options when erasing. Unibeast 8.1 installed fine, so it definitely wasn't a problem with the drive.

Here is my diskutil list from before I used the above solution. Hope it helps someone figure this out.

diskutil list
/dev/disk0 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *251.0 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_APFS Container disk1 225.6 GB disk0s2
3: Linux Filesystem 20.5 GB disk0s3
4: Linux Swap 4.7 GB disk0s4

/dev/disk1 (synthesized):
#: TYPE NAME SIZE IDENTIFIER
0: APFS Container Scheme - +225.6 GB disk1
Physical Store disk0s2
1: APFS Volume Macintosh HD 168.7 GB disk1s1
2: APFS Volume Preboot 20.5 MB disk1s2
3: APFS Volume Recovery 520.8 MB disk1s3
4: APFS Volume VM 3.2 GB disk1s4

/dev/disk2 (external, physical):
#: TYPE NAME SIZE IDENTIFIER
0: FDisk_partition_scheme *30.8 GB disk2
1: Apple_HFS SanDisk 30.8 GB disk2s1

/dev/disk3 (disk image):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme +2.1 GB disk3
1: Apple_HFS OS X Base System 2.0 GB disk3s1​

Now that I'm looking this over, I think my mistake was using /dev/disk2s1 instead of /dev/disk2.

/dev/disk2 totally worked. An oversight on my part, thanks InvaderSteve and macman for the help!
