Whoa. Current indications are that trouble may be with the drive – the hardware – not with ZFS or ZEVO.

(I assume that you have no complete backup of that drive.)

Something is wrong with the Western Digital web site. Their link to My Book Essential no longer works :(

For a different type of Western Digital My Book, reviews by Apple users include some comments that might be useful:


Thoughts

If Western Digital software is installed, try uninstalling that software.

When the Western Digital web site is working properly again, see whether the firmware on both drives is current.

Postscript

Afterthought … if your original Western Digital drive has a hardware problem, then connection may be lost before a check of firmware is possible.

You could/should check the firmware for the new drive. If it's outdated on the new drive, then we might guess that firmware is similarly outdated on the original drive.

Then consider the steps in my earlier post

So then what you're essentially saying is that my data is lost forever?? There's no way to get it back?

That's not the essence. Please review recent posts. We're closer to identifying a point of failure.

My hope today is the same as my hope yesterday: that the disk, within the USB drive enclosure, will be OK.

Re: Mac hard resets when mounting external HD

Hello,

I have a brand new Mac mini... that I literally just turned on for the first time. I installed Zevo Community and plugged in the external ZFS drive. Mac OS X crashed and restarted by itself. (This is a completely clean copy of OS X... it's a brand new Mac).

However the ZFS drive did show up in Disk Utility but failed to mount.

I've attached a screenshot and console log.

Please HELP ME retrieve my data!

I't been over a month now!

Glad to hear from you again. It's ideal to have good Mac hardware, plus a clean installation of the operating system, as a foundation towards pinpointing the causes of the problems.

Very quick check – an essential for ZEVO with Mountain Lion – in the ZEVO pane of System Preferences, which of these two versions do you have?

  • 1.1
  • 1.1.1

Hi,
I literally downloaded Zevo community from this website. So should be the newest...

Whatever Greenbytes posted (As of last night)... that's what I have installed/

Were the log files (that is the COMPLETE log file from Console as it is a brand new Mac)... helpful in fixing this problem??

I really need my data.

Not necessarily. There are two downloads: the full installer, and a smaller download for an update.

Please, which version is shown in the ZEVO pane of System Preferences?
