"The disk you inserted was not readable by this computer." With "My Book For Mac" 3Tb External HardDrive?

Hi!

Same problem with my Lacie 2TB HDD with lots of important files!

I found a good solution on my mac and wish it works for you as well.

1.Make sure you use the latest version of OS on your mac. As I use macOS Sierra V 10.12.6

2.when you see the blowing massage click on "Initialize..."

3.On "Disk Utility" click on First Aid and the Run. Be patient until you see the green checkpoint.🙂

(Now you probably see the actual name of your drive. But it should be still disabled to work with.)

4.Find this application somewhere! ( I used V.14.2.228)

you can use the free version of it as well for 1week.

Paragon NTFS for Mac 15 - Skriv-/läsbehörighet till NTFS under macOS High Sierra - Introduktion

5. First "Verify" you volume and the "Mount" it!

I wish you can use your volumes as well 🙂

Make sure you have power to it with the supplied charger

Go into disk utility and format it for MAC OSX extended journaled.

Disk Utility below > Erase > Format in Mac OS extended journaled.

So you cannot drag any files to your WD desktop 3.5" 3TB? ..... Or have you not tried, OR cannot get that far?

It shows up fine in D.U. by your pic,......new drive, so....

Initialize the drive. 😊

verify by dropping some files on same afterwards

*edit

What was it ?

How did you resolved this ?

He just needed to initialize it.

Another desktop quirk of WD.

seen it sometimes.

I have the same problem. Bought a My Book 3TB for Mac and dropped it. It wasn't doing anything so I bought the Vantec Nexstar 3.5 sata 3.0 drive enclosure hoping it wasn't the drive. Now I'm getting "The disk you inserted was not readable by this computer. When I click on initalize the drive show up but I'm not sure what to do here. Can you help me?

Hi everybody, if I can say this error message does not appear just when external HDD attached. I have problem to burn any CD / DVD and I believe it happend after latest security update. I am using Mac OS X Mountain Lion.

i have this problem ..my external hard drive is fill with important data for me .. how can i out of this error

"the disk you inserted was not readable by this computer"

whithout loose my data ..

what should i do here after pressing initialize..

I get this all the time when I boot up my WD externals. The two options are Ignore and Eject. I choose Ignore, the message goes away, and everything works fine. But if anyone knows how to stop these pesky warnings, I'd love to hear from them.

Having same problem with 2 hard drives. The hard drives are all working when inside the WD enclosure. But when you use a diffrent SATA to USB external connector, it flashes the "The disk you inserted was not readable... etc".

Could it be that the WD enclosure has written some codes into the drive that makes it exclusively readbale when using the WD enclosure.

I have the same experience with Seagate enclosure. It appears that external drives that ahd been connected using their enclosures cannot be read when using another connector.

Is there a way to fix this?

I have just started having this same issue within the last week. Looking forward to a solution appearing here.
