Jul 17, 2015 3:36 PM in response to jf123by Kappy,Try this:
Repair the Hard Drive and Permissions - Yosemite, Mavericks, Mountain Lion or Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears.
Repair
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu. Select Restart from the Apple menu.

The hard drive shows up in Finder but opening and transferring files is incredibly slow.
If you have not tried this yet -- use the shut-down option from the mac icon to power off your computer. Wait a minute & power back on.
Some times that is the only way to clean up conflicts.
