Seagate Backup not visible in finder on macbrook pro retina display
My Seagate Back up has stopped displaying in finder
Have checked the threads online. Finder preferences have been checked. An update on the drivers has been done.
Does not appear in disk utilities either.
I have also upgraded OS to Yosemite.
Can't work out if the drive is malfunctioning or whether there is set up issue.
The light on drive powers up and the drive itself is spinning.
Nervous about doing anything that will wipe the data on the disc as it valuable.
Can anyone assist or advice whether I should take it to a third party for investigation?
cheers
Kathy
