My Book making noise. Is it dead? Is there hope?

So that’s the noise it’s making when I plug in the USB cable. Does not mount/show up on either of my Macs. Is the drive dead? Did I lose everything or can it be fixed? Anything would help.

Thanks.

Hello there,

It would seem that the unit is defective, I suggest trying to contact a data recovery company or using data recovery software in order to try and get your information back, Please check on this link bellow to see if you can find some helpful information:
