Re: Is one of my drives dead?

My Book Essential 2 TB for mac just made the same situation - suddenly it is dead - no light in it - did I loose all info on the device then?

To determine if the drive failed you can try:

  1. Different cable
  2. Different power adapter
  3. Check Disk Utility

Try the steps on the link bellow:

WD external drive is not assigned a drive letter by Windows or Mac OSX and data on the drive is inaccessible
