Go to the Finder menu bar and choose Finder > Preferences.
Now put a check mark in the Hard disks, External disks, CDs, DVDs and iPods check boxes.
Should solve the problem
P
I ran into a problem that ended up requiring the tech at the Genius Bar to do a clean reinstall of the System (OS 10.9.2). I am not able to migrate my software over from the Time Machine backup because that re-creates the problem. So I have to re-insall all my software from scratch. Kinda labor intensive.
The immediate problem is that the iMac's hard drive, the startup drive, does not appear on the desktop, nor in a Finder window. This is apparently not unusual as it happened while the tech was working on things at the Apple Store (we wiped & reinstalled several times.) It is, however, inconvenient.
The tech did something simple and the drive appeared on the desktop. I do not remember what it was, and have looked through all the Finder menus and System Preferences items. Any help here?
