Oct 31, 2013 8:05 AM in response to Blake McKimmieby altery,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.

Oct 31, 2013 8:05 AM in response to Ryu01by kilgo,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

Oct 31, 2013 9:03 AM in response to xboxtremeby jordan8037310,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.

Oct 31, 2013 9:23 AM in response to jordan8037310by broomst,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!!

Oct 31, 2013 9:41 AM in response to xboxtremeby lowflyer7,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.

Oct 31, 2013 11:48 AM in response to xboxtremeby deltaguru,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
