Thats the final piece. (and you swapped out HD USB cables too on the 'bad' HD?). After swapping cables between the '2 identical WD USB HD', you have (nearly 100% certainty) a bad SATA card as I stated much earlier. The case being, your other Macs will read/ write to this HD fine, but this one Mac wont. It makes very little logical sense to most (for obvious reasons), but that that one Mac is no longer able to communicate with said HD due to the SATA card.This is why some of us HD 'collectors' call this the 'haunted HD syndrome' 😐, where a HD acts utterly illogical and contrary to common sense diagnostics (works fine on ONE Mac but not another) You have 2 options, offload all data onto another HD that will work on that one Mac, OR crack open the HD case and remove the HD itself and put into another enclosure ($10-15$ ebay). A SATA card is about the size of a stick of gum, its plugged into the HD with a female USB connection on the other side, it unplugs in 1/2 a second from the HD once you get into the HD casing. Its a (junky) 50 cent part.
If a HD is over 3 months old (most all 'bad' HD fail usually before the 3 month mark) and LESS THAN 5 years old and treated very well.people that assume a non-working HD is a 'bad' HD when in fact the HD is just 100% fine, its just that miserable little circuit card. I have the same problem. I have an old MacBook Intel Core 2 Duo, OS X 10.7.5 and WD Passport works without fail. I tried 10 other MacBook Pro, MacBook Air, Mac mini. All of them installed OS 10.9.x or 10.10. The WD Passport never mounted to the desktop on USB 3 port.
Before it couldn't find the SES Driver, but the 'WD My Passport 0730 USB Device' still fails to install. The drive now shows up in Device Manager as 'USB Mass Storage Device' as well as 'WD SES Device', but it doesn't show up in diskpart or anything else. Feb 29, 2016 WD My passport - Not recognized in Win 10 I am having WD My passport Ultra (1tb) and its not recognized in any USB 3.0 ports, after initial one time! WD Drive Management device *WD SES Device - USB Mass Storage Device show the Passport controller has been properly detected. The DM looks normal except you didn't open up the Disk drives.
It would be cool to see how much advantage could be taken of the similarity in hardware between the GC and Mac in an emulator, though. From all of my friends with a PS2 or X-Box, at least one of their games is a bootleg or illegal copy. Nintendo gamecube emulator mac. Click to expand.Sometimes I wonder if pirating helped the current video game consoles.
It never seemed in the Disk Utility. If I tried to disconnect USB cable - any cable, I tried more - very very slowly, then the disk became MOUNTED on desktop!
(Pull out USB plug one third part!) And it doesn't matter how it'was formatted. The format and the partition table was irrelevant. Slow disconnecting movement always worked on all machines. You can try it too.
If it's working, then It's a very fine joke. Ridiculous insufficiency in cooperation of Apple and WD.
OK, so contrary to what you originally said it CURRENTLY does not work on ANY Mac? If that is the case, you have a bad cable (very unlikely) or (very very common) a bad SATA card inside the external HD case. Meaning.almost certain your HD is fine, but the SATA bridge has bit the dust (typical). Youd have to crack open the case and put the HD into a HD enclosure ($15 on ebay) or a HD dock (35$ on ebay, or best buy). BEFORE all that of course, verify that the USB cable isnt bad (trying another) and trying same HD on another Mac.
UPDATE: Ok, so it reads fine on other devices, but not the Mac currently. Offload all data on the HD onto another computer, format the HD for ExFat so it can read/write from / to both PC and Mac load all data back onto HD. Got it, now your current macbook isnt recognizing THIS hard drive, or ANY hard drive?
Do you have another HD to test on the problem macbook? Do an SMC reset of the macbook in question. Shut down the computer. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time. Release all the keys and the power button at the same time. Press the power button to turn on the computer.
Ok i tried that, how do I know if it worked? I shut down my laptop completely with the power cord in. I think pressed all the buttons you told me to. After I released them simultaneously, nothing happened (i'm not sure if something was supposed to) but then I pressed the power button and everything booted up as normal. This WD My Passport DOES work on all other devices. I do have another macbook and it works perfectly fine on it.it's really perplexing.
After resetting the SMC it still doesn't show up: (. Thats the final piece. (and you swapped out HD USB cables too on the 'bad' HD?).
