Wd My Passport Won'T Power Up Crack Open The

While it was downloading, my Macbook Pro just froze up on me, so I had no choice but to turn it off manually.

After I turned it on, my hard drive wont appear on the Finder AND the Disk Utility Usually in the past, it wouldnt appear only on the Finder.

An intermittent wonky SATA card seems the highest likelihood here inside the HD enclosure.

It powers up normally and I see the light on the HD, it reads on other macbook pros and it even gets read by my LG smart TV.

It used to be read on my macbook pro but for no reason it just doesnt show up anywhere, not even on disk utility.

Has anyone experienced this problem or have any recommendations for me thanks.

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 12 a second from the HD once you get into the HD casing.

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 an old MacBook Intel Core 2 Duo, OS X 10.7.5 and WD Passport works without fail.

But 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 doesnt matter how itwas formatted.

You can try it too.

If its working, then Its a very fine joke.

You will need to hold these keys down simultaneously in step 4.

I forget what it was formatted in.but it worked fine for the longest time.

It literally works in every device, laptop, tv, except my macbook pro.

Im baffled. Ive tried all sorts of things like different cords, ports, etc.

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.

As soon as I plug it into another macbook it comes on right away and is visible in Finder.

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.

After I released them simultaneously, nothing happened (im not sure if something was supposed to) but then I pressed the power button and everything booted up as normal.

I do have another macbook and it works perfectly fine on it.its really perplexing.

Said drive would spin up and powerup but not pass on one Mac but would on others.
