I have a 4TB external SSD. Running Diskutil I get
/dev/disk3 (external, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *4.0 TB disk3 1: EFI EFI 209.7 MB disk3s1 2: Apple_APFS Container disk7 2.2 TB disk3s2 3: Apple_Boot 650.0 MB disk3s6 4: Apple_APFS Container disk4 1.8 TB disk3s4 /dev/disk4 (synthesized): #: TYPE NAME SIZE IDENTIFIER 0: APFS Container Scheme - +1.8 TB disk4 Physical Store disk3s4 1: APFS Volume SSD 1015 - Data 1.6 TB disk4s1 2: APFS Volume Preboot 87.0 MB disk4s2 3: APFS Volume Recovery 528.9 MB disk4s3 4: APFS Volume VM 19.3 GB disk4s4 /dev/disk7 (synthesized): #: TYPE NAME SIZE IDENTIFIER 0: APFS Container Scheme - +2.2 TB disk7 Physical Store disk3s2
My goal is to have /dev/disk4 be the combined size (~4TB). It is now about 1/2 the size of the physical disk. 4TB is the size of the physical drive size, but it got split into 2 partitions as i was upgrading from Mojave to Catalina (long story as I couldn’t just upgrade because the SSD was originally HFS). I did get rid of the HFS partition and converted to APFS. /dev/disk7 is now blank. /dev/disk4 is now my boot drive.
I really don’t want to have to reformat the SSD (boot disk) if at all possible. I tried
sudo diskutil apfs resizeContainer disk4 0
but that didn’t work.
Is this possible? I also tried using disk utility, but it didn’t seem to want to resize up either.
Can someone steer me in the right direction? — Thanks
