I had a boot drive go bad on my main work system. I have found the drive to be defective but I do have back up Carbon Copy Clones. Strangely when I hold option on startup I don't see the back up carbon copy clone as a choice I see EFI along with a different carbon copy cloned startup drive. I turns out the EFI is really the backup clone. Once I booted to the other drive I was able to see the actual name that appears on the desktop in start up drives and I selected it and restarted to it. I did some googling and found various thoughts one of which was that using Disk Warrior 4.2 to rebuild the directory of a boot drive might cause this. Another suggestion was the partition was not the correct GUID format. I'll have to look into this further but the system is running.
The bad drive will boot up and show the desktop but clicking on anything causes beach ball spin for a minute or so and trying disk utility on it stall the disk utility. I'm going to take the bad drive home to see if I can do anything with it in a cradle just to learn what's up or down in this case.
Can anybody shed some light on why the drive appears as EFI when holding option down on startup but then had the normal name on the desktop and start up drive preferences?
