I've noticed that when I run Disk Utility from the boot disk and choose "verify disk", it tells me that the volume needs to be repaired; after repairing, I choose "verify disk" again, and I get the same message that it needs to be repaired, so I repair once again, verify, same message ... I've repeated this procedure 5 times and I still get the same message. Should I keep repairing until I get a message that "volume 10.2.6 appears to be ok"?
