- mac mini late 2012 2.5ghz i5 osx 10.9.5 500gb 16gb ram and iMac 27" mid 2010 i7 2.93Ghz OS X 10.10.1
My Iomega 320gb - 5 yr old - external hd (externally powered) drive is not seen by Yosemite following upgrade on my iMac i7 mid 2010. It is not visible on disc utility nor is it reported on sys info. I have tried different usb's and unplugged other usb's. It works fine on mavericks on my mac mini. I have reformatted it from msdos to mac journal on the mac mini and it is still not recognised. This must be a Yosemite issue but Iomega site is no help. It looks like Yosemite needs a driver to recognise it maybe. Any ideas guys?
