When I bought my 2 TB Western Digital external hard drive a few months back it came with a new feature that made a lot of sense–WD Unlocker, which allowed me to password protect the drive in case I ever left it somewhere or someone stole it.
Well, what I didn’t know is that when hard drives on a Mac go to sleep, they shut off the password protection on the external drive and until you go through the password process again, it does not work. And, I’ve been getting these -50 error messages from my Mac ever since. A call to Apple Care recommended resetting the Power Saving features of my Mac back to the factory settings, but I am here and then step away from the Mac all day long and the factory settings really aren’t acceptable.
Worse still, is that my 800 GB Aperture Library is on this one drive, too. And once it goes to sleep, and you try restarting Aperture, chances are high you’re going to get an error message. (See above.)
I’m sorry, but this really isn’t acceptable, either on the part of WD or Apple. To their credit, Apple tried to help me fix this. I’ve searched Google a couple times about WD Unlocker and there’s just not that much out there.
So here’s the solution I’m adopting. Right now, I’m two hours into what said was a four-hour transfer–even using a USB 3.0 connector and sending it to a G-Drive running thru Thunderbolt, it’s still taking five to six hours to transfer the 800 GBs.
When that process is complete, I’m going to reformat the external drive and start over. This is taking far too much time to do, but in the long run, it’s going to save me a ton of time. Getting to the back of an iMac every time my machine goes to sleep has become a royal pain, not to mention an unnecessary one.
WD, you need to work out with Apple to resolve this. The whole thing with Aperture has been more than I should have had to deal with and I count this as your fault.
There also doesn’t appear to be anyway to simply turn the PWD thing off. Your instructions for that are not easy to understand.
So if you’re out there and wondering should you install WD Unlocker on your external drive, my recommendation is don’t, unless you have tons of time to waste and like -50 error messages.
