Q: Mybook studio raid 0, empty after installing Mavericks

After installing Mavericks, my WD My Book Studio II connected by firewire, does not contain any files. It is a raid 0, after using the operating system while I wonder if I could use time machine to which I said no.

In this hard drive I keep my most precious files.

Forgive the level of English, I'm Spanish and I write through a translator.

A greeting and thanks.

Mac mini (Mid 2011), OS X Mavericks (10.9), Raid 0

    Are only RAID Drives affected? I own a WD MyBook Elite (1 TB, USB 2.0 only).

    I haven't done the upgrade to mavericks yet. If non-RAIDS like mine are affected, i'm gonna wait.

    Same issue for me. WD My Book Studio II was conntected using Firewire 800 to my Thunderbolt display during Upgrade to Mavericks. A few days later, my two partitions (NTFS and HFS+) were gone and replaced by a EFI EPS and a HFS+ partition. No data is accessible anymore

     

    Additional note: The drive was configured as RAID 1 using the WD Raid Manager Utility. The Utility was still installed during/after the upgrade.

    Ryu01, I have heard about non-raid users affected as well.

    I have 6 (non-raids) and they all work. Have been backing them up, transfering large amounts of data back and forth...no problems so far. Have had Mavericks for about a week.

     

    BUT THAT COULD CHANGE, and I am aware of that. I have multiple back ups of the same data so If one drive goes I have another Identical drive that I will leave "Offline".

     

    AS WELL AS, I formatted my drives the moment I hooked them up with Apples Disk Utility I never used Smartware.

     

    Don't know whats going on but I know from experience this kind of thing ***** and I hope those people affected come out O.K.

     

    BTW...I'm on an older system...MBP 2008 Unibody, USB and Firewire, not using Thunderbolt

    Kilgo - are your drives GUID or APT formatted - that I think might be the key here

    This post really scared me.

     

    I also have a MyBookWorld 4TB RAID0. Fortunately, I did not have any resulting data loss.

     

    The details of my upgrade: I did not have the WD RAID Management software installed during the time of upgrade and there was no resulting loss of data. I also did not make the upgrade while plugged into any hard drives.

     

    Hope this helps.

    My WD Studio 1TB redid the deed last night just over a week after upgrading to Mavericks - don't assume that this is an upgrade only issue!!

    I just received advice from WD to remove all WD Software and restart my computer. Other than that they just told me to wait, but reading all posts here I still don't think it's safe to attach the HD again.

    Hi,

     

    I removed all the wd services manually because the uninstaller is not available anymore by WD.

    Look into:

    • /System/Library/LaunchDaemons/ - System-wide daemons provided by Mac OS X
    • /System/Library/LaunchAgents/ - Per-user agents provided by Mac OS X.
    • ~/Library/LaunchAgents/ - Per-user agents provided by the user.
    • /Library/LaunchAgents/ - Per-user agents provided by the administrator.
    • /Library/LaunchDaemons/ - System-wide daemons provided by the administrator.

     

    • Delete all starting with wd.... like wdservicemanager.
    • Reboot and check the Activity Monitor for still running wd-processes.

     

    There will be one left the "wdhelper".

    Then the tricky part:

    • Login as root (check Apple documents how to activate root)
    • Go to ./usr/libexec
    • Delete wdhelper by moving it to the trash bin.

     

    Reboot and Voilà

     

    May the force with you
