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

     

    That may resolve the issue.

    Can't repair it if it's the boot volume. To do that requires booting into recovery mode and running Disk Utility from there.

    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?

    It is possible that it may be going into failure mode, as what you described seems intermittant, make sure your backups are up to date, and do them often in case it does fail.

    Errors reported when doing  verification are not reliable.

    As long as there are no errors reported when repairing the disk while  booted into

     

    Recovery HD, dIsk is fine.

    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.

     

    Best.

    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.
