When you get the message "needed repair" next time, click Repair Disk button.


That may resolve the issue.



Best.

Do you have FileVault turned on?

Sometimes this kind of anomaly can result from that.


I am sure that you have a proper, reliable backup.

Thanks dominic and baltwo. I carried out a disk recovery from recovery mode and this ran and said disk ok.

The next time I rebooted mac I ran verify disk and it again and it said disk corrupt ect.

Today after another reboot and me having taken no action re above verify disk says hd ok- is it or is it breaking down?

If you make a bootable backup of your int HD onto an ext HD, boot with that, then you can erase and reformat the int HD, restore the backup, and run DU again. That usually fixes what's ailing on the HD.
