alright I'm going to bed... I'll check in about 8 hours.

thanks.

I just really really hope that I can get access to my data ASAP so that I can at least copy the data off that drive, I have another blank 3TB hard drive that I can transfer the data too.

OK. According to Western Digital, WDBACW0030HBK is not the My Book Home Edition; it is the My Book Essential Edition 3 TB.

– so I assume Advanced Format, but from WD information (and a little Googling) I can not tell whether WDBACW0030HBK is 512e or 4Kn; or whether the true native sector size is hidden by the bridge.

I'm almost certain it's Advanced Format drive... that's what it said on the box as one of the selling points I believe...

Thanks. Can you recall whether the Advanced Format was recognised as such in ZEVO Setup Assistant, when you originally ran the assistant for that disk?

Here are some more system log files that was asked for.

Is anyone able to investigate this further please? I really hope that I will be able to retrieve my data.

kernel panic reports in Console and in Finder

Post by grahamperrin » Fri Oct 05, 2012 2:15 am

In an earlier .zip archive:

    PluginProcess_2012-09-28-223931_administrators-macbook-pro.crash
    PluginProcess_2012-10-02-172806_administrators-macbook-pro.crash

In the .zip archive above:

    kernel-shutdown.log
    system.log

Panic reports, also known as .panic files

Maybe of greater use to the developers will be panic reports.

With Console: browse first to System Diagnostic Reports, then to files where the name begins with Kernel…, then select a file with a name that matches the date and time of the incident (example):

system diagnostic reports in Console.png
system diagnostic reports in Console.png (164.83 KiB) Viewed 63 times


a .panic file in Console.png
a .panic file in Console.png (222.67 KiB) Viewed 63 times


– observe the .panic extension to the filename.

In the title bar of the Console window, Command-click the title to reveal the proxy icon menu. Release the Command key. Pull down one step, to the folder that contains the file …

proxy icon menu selection of a folder.png
proxy icon menu selection of a folder.png (216.46 KiB) Viewed 63 times


… then release the mouse.

The operating system will automatically:

  1. open a Finder window; and
  2. select the file that was in the proxy icon menu.

Create a .zip archive of: that kernel panic file, and any other kernel panic files that may be relevant to this topic. Then please attach to this topic.

Thanks

I had no idea the Mac kept that kind of diagnostic history data... almost like a black box... That's really good.

Thank you for that excellent explanation and step by step (with pictures) tutorials! (that was a HUGE help).

I included all the Kernel Panic files as well as the relevant Transmission Hang files (Transmission was running and writing to the hard disk I guess the errors started happening).

Please find them attached in a Zip file.

Thanks. All five .panic files appear similar.

I don't have developer skills to interpret them, someone else (probably at GreenBytes) might do so.

For convenience, an extract from the most recent of the five:

Thanks,

Can anyone at GreenBytes or Don Braddy please help? I still don't have access to my data.
