disk utility restore external hard drive

I've found a 3rd party alternative solution, Carbon Copy Cloner. Nevertheless, I have now checked all volumes on both disks with First Aid in DU, and all are reported as 'OK'.īased on all the above, I've concluded that my Recovery volume is unreliable and not fit for purpose.

The source disk is a Crucial SSD, a few years old & no known issues the destination disk as also a Crucial SSD - about a week old.

Whatever the version of DU in the Recovery volume, the failure I experienced seems rather chronic.

The version of Disk Utility ( DU) in the Recovery volume of my MBP is the same version as DU in my 'primary' High Sierra volume - it was apparently upgraded concurrently with the High Sierra upgrade.

The upgrade to High Sierra converted the 'primary' volume to APFS, but left the Recovery volume as HFS.I initially concluded Apple had simply not upgraded the Recovery volume or the apps in it, but this proved not to be the case. But instead of seeing a 'Success' message this morning, I saw an error: Inverting target volume.ĪPFS inverter failed to invert the volume - invalid argument designate source (500GB) & destination (1TB) drives.boot with command- R to get into the Recovery HD volume.Finding no warnings, cautions or surprises, I began the process: I quickly reviewed this article to verify nothing had changed. I did this previously when upgrading the original mechanical HDD to SSD, but it was HFS-to-HFS. I will use Disk Utility from the Recovery HD volume to do this since both source and destination volumes in the cloning process will need to be unmounted. I can accomplish this by cloning the 500GB drive to the 1TB drive. HDD: 500 GB SSD, w/ Macintosh HD & BOOTCAMP partitions.I need to upgrade the drive in my Macbook Pro.
