Oct 17, 2013 11:57 AM in response to dominic23by baltwo,★HelpfulCan't repair it if it's the boot volume. To do that requires booting into recovery mode and running Disk Utility from there.

Oct 19, 2013 9:35 AM in response to cfrombarrheadby cfrombarrhead,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?

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.

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.
