Q: Disk utility not showing external hard drive

Hello all,

 

I'm having issues with my external 1T WD My Passport for Mac. I was transferring a large amoung (10gigs) of pictures onto to it when it made a high-pitched click-like noise and stopped being recognized by the computer. Since then it has not been recognized by any of the 3 MacBooks that I have access to (I do not currently have access to any Windows devices.) I have tried multiple USB cables to no avail, and this particular hard drive did not come with a power source/adapter nor has ever needed it.

I am running OSX Yosemite (V10.10.5)

 

I've troubleshooted to the best of my abilities and this is what I have:

The device does NOT show up in Finder

The device does NOT show up in Disk Utility

The device does NOT show up in Terminal when diskutil list command is used

The device DOES show up in System Information, and gives me the following readout:

 

My Passport 07B8:

 

  Product ID:    0x07b8

  Vendor ID:    0x1058  (Western Digital Technologies, Inc.)

  Version:    10.07

  Serial Number:    575832314143343559454E50

  Speed:    Up to 480 Mb/sec

  Manufacturer:    Western Digital

  Location ID:    0x14100000 / 9

  Current Available (mA):    500

  Current Required (mA):    500

 

I can feel the drive running and the LED is flashing just like it did when it ran without issue. It will occasionally make the high-pitched click noise, usually if I have it connected to the computer while booting on/off.

 

Any assistance would be great! As I said, I'm pretty stuck.

 

Thanks!

MacBook Pro (Retina, 15-inch, Late 2013), OS X Yosemite (10.10.5)

    Sounds like it has failed.

    see if the drive is under warranty. WD might replace it if it is but your data is probably scrambled if you can't read the drive on any other device.

    Update: After not touching the drive for two days I plugged it back in and it mounted with no problem, a bunch of the data is corrupted but I managed to get some off of it. Running idefrag on it as a last-ditch effort to try and get some more data off of it... it's taking forever though.
