How does the disk load ?

Every Mac that has an optical drive has an eject key on the keyboard. Pressing the eject key will eject a CD or DVD.

The eject key has this icon on it: ?

You can also right-click on the disk icon, then choose "Eject" from the pop-up menu.

You can also click once on the disk icon, then choose "Eject" from the File menu.

You can also drag the icon to the Trash icon in the dock.

The eject key will only eject CDs and DVDs, but all of the other methods described above will also unmount other media types, like a hard drive or flash drive connected via USB, FireWire, or Thunderbolt.

it is common problem when installing unsigned driver. please select the 'install driver anyway' when got pop-up window option. Thank you.

It depends on the manufacturer of the docking station. What is the model of the docking station you purchased?

if you cant remember your password you must use your recovery disk but this will mean you'll format your hard drive so all your files will be deleted or you could use a program called hdd unlock youll need a computer to do this because laptops only have one docking station for a hard drive to save space if you do have a computer connect your hard rive using a docking station download this program for your hard drive to be usable again http://www.hddunlock.com/download/.

So any disk produces this result? You may have a bad drive, but without further explanation, it's really impossible to say.

Buy a HHD docking station that you can drop your SATA hard disk drive into. you plug the Docking Station into an avalable usb port.
If you can't use the hard disk with this docking station the disk is bad.
This works about 99% of the time, great method for using or recovering old files (pictures, files) off of used hard drives.

Be persistant-shake the F&^% out of it. Face it with the disk slot facing down and just shake it a few times. Worked for me.

mechanicall problem..drive need to be opend....be carfull

FWIW, I had the same problem...here's what I did.

I would insert a disk and it would get ejected immediately...didn't even look like the light in the eject button would flash. Rebooting the drive and computer didn't work.

I inserted a disk.
Before it could be ejected, I pulled the plug on the Rev Drive.
I waited several seconds
Re-plugged in the rev drive.

It seemed to read my disk and I was able to use my Rev drive. (So far so good...knock on my wooden head.)

Luck
