Disk utility updating boot support partitions
If i plug it back into my Pi after this it goes through the boot process as i mentioned above, so this shows it has not actually been reformatted.If i plug it into my Mac it does not show in Disk Utility, however i am able to see it in terminal and it shows up as: Karls-i Mac:~ karljeffery$ diskutil repair Volume /dev/disk4s1 Started file system repair on disk4s1 boot Updating boot support partitions for the volume as required Error: -69673: Unable to unmount volume for repair So, looking at the various results, it seems like all my problems would be solved if it could 'unmount' the card and just get on with the job!Running File Optimization after Volume Optimization should not have caused disk directory damage. Mike Hayden On Oct 30, , at 9: Meanwhile, I'm wondering if the problem was instigated by a slight change in my regular procedure So it's great to have an expert to rely on when the computer decides to stump me.The next morning, based on the graphic and associated data, everything looked like Volume Optimization worked fine as usual.
I ran disk utility, selected the drive, and clicked repair disk...said all the stuff, then said "Updating boot support partitions for the volume as required." and says "7 minutes" but has been stuck there for hours!Anyway, since my computer is only about 6 months old, it's under warranty.Freshfield, Liverpool, UK This expert is wonderful.But, the data indicated there were files still fragmented, so I ran File Optimization after Volume Optimization.
