By the way every single time I plug in my external ZFS drive, I have to hard shut down my Mac holding the power button because Shutdown will simply hang.

Following Don's advice: try using a different Mac and a different cable to rule out any hardware issues.

I don't have access to another Mac.... especially one that I can install ZFS on it.

I bought the exact same hard drive again, used the new USB cable and power supply adapter and attached it to my ZFS external drive... it still did not mount.

Please help.

I attached the new logs from console.

Also, this time connecting the external drive caused my system to hang. I had to hold the power button because everything stopped working.

If I understand correctly … 

  • without the new Western Digital My Book Essential Edition 3 TB
  • with your original My Book Essential Edition 3 TB
  • with the new cable
  • with the new power supply:

Yes that is correct... new cable and power adapter... connected to my ZFS external USB drive.

does that help?

Am I closer to mounting the drive in Finder so I can recover my data?

I bought an identical My Book 3TB in the hopes I can move my data from the existing drive because ZFS is causing all this trouble. (I just want and need my data)

I reckon that next steps should be:

  1. until further notice, set aside the original drive
  2. restart the operating system
  3. install ZEVO Community Edition 1.1.1
  4. restart the operating system
  5. use the new cable and new power supply to connect the new drive
  6. connect nothing else to your MacBook Pro
  7. use diskutil list in Terminal to see whether the new drive is at disk1
  8. give the new drive to ZEVO.

If the new drive is at disk1, then the command for giving should be:

Code: Select all
sudo zpool create -o ashift=12 newdrive-2012-11-01 /dev/disk1


That should create a pool named newdrive-2012-11-01 with a file system named newdrive-2012-11-01

– the distinctive names should help, in the future, to remind us of the date when these steps were taken.

Then … see whether the new drive is reliable with ZEVO Community Edition.

Don, please, is that a reasonable set of steps?
