Hello all, I have a WD My Passport for Mac in 1TB and I believe it is USB 2.0. I am trying to use it on a Macbook Pro Retina 2015. Its about 2-3 years old. Last night I updated it with everything from my designs, and projects and tried to do all my music. I have 14k songs and stopped it when I realized it was not loading after a few hours. I just plugged it out without ejecting. Today, I'm trying to use it and it will not mount.


Western Digital’s My Passport For Mac is a solid, compact, comparatively speedy little USB-only portable hard drive that also happens to be Time Machine–ready and designed for the Mac. Asus n56dp driver for mac.
The light on the front flashes rapidly when I first plug it in and I can feel the hard drive moving. It then slows and the light stops flashing all together. Now, I'm at a very steady flash but still no mounting. It does not show up in Disk Utility. If anyone knows what I should do to be able to see the drive, or to get the items off the drive, please let me know.
I cannot reformat because you need to see the drive to do that and this was my way to back up things from smaller thumb drives which were full because of the items. Should I just plug it in and wait? My thumb drives work fine in both USB slots. I also tried to use the external hard drive on a Macbook Air and it did not mount there either. Any tips would be helpful.
Hello Benwiggy, No. This was my back up drive. I hardly use it unless my thumb drives are full. The hard drive works because it lights up, and I have taken it out of the enclosure with no luck. I also tried to see it in Recovery Mode and it did not come up in Disk Utility. I took the case off but the USB slot where I plugged the USB into is still the same. I also tried a different cord.
Am I only removing the Plastic Casing or the Silver piece attached to the drive? I tried to use a free recovery tool and the drives wont show up there either. I'm not sure what to do anymore. It works and it blinks, its spins, it clicks, everything is normal but it just wont mount. When I took it out, I didn't put it into anything. I thought I could use it alone with no casing? The USB Port, am I supposed to remove that or just the plastic casing?
