I have several external hard drives attached via USB to my iMac. Turning the Mac on this morning, three of the four drives mount no problem. (all in the same ext power / usb tower) but one drive does not mount.
I went into Disk Utility and the drive shows up there but it's child shows up greyed out. When I select the child it shows that I can mount it but when I actually hit the mount button nothing else happens. The button does not show unmount but stays as mount.
It shows the child as being all yellow (other) but it's far from full.
Can anyone help?
It didn't mount:
