True, all RAID setups appear affected, including all the WD MyBook
even Seagate RAID are corrupted with total loss of metadata, dont connect any MyBook to Mavericks, or any RAID

We are looking into this right now.

I removed WD folders from Library/Application Support and all files with WD in their names from System/Library/Extensions. Finally the WD Drive Manager does not show up in the menu when I connect the formatted MyBook Studio Ed II 6TB.
BTW my Time Machine is on a 2TB single hard disk WD My Book drive and it's working fine under Mavericks with and without the WD software. "seriously" said that his WD RED disk has not been affected but his WD GREEN disk on the same dock has been formatted to "MyBook". I wonder if this could be a Red/Green problem as well as a RAID problem.

I'm another pissed off WD user.
I have just lost 10TB of data. All the contents of a 6TB WD and a 4TB Seagate drives have been wiped out. Both HDs have been renamed "MyBook".
I'm not sure if I should wait for a solution from Apple or WD or if I should start trying to recover the data with Data Rescue or Disk Drill. Any thoughts?

OK, I took a peek inside my ruined 6TB RAID drive and the unaffected 2TB single disk drive, they are all WD GREEN disks. So it looks like that's not an issue.
C'mon WD and Apple already! We are dying here!

On October 30th, 2013 Western Digital informed registered customers of affected products via E-mail regarding reports of Western Digital and other external HDD products experiencing data loss when updating to OS X Mavericks (10.9). Our investigation to date has found that for a small percentage of customers that have the WD Drive Manager, WD Raid Manager and/or WD SmartWare software applications installed on their Mac, there can be cases of a repartition and reformat of their Direct Attached Storage (DAS) devices without customer acknowledgement which can result in data loss.
WD has been tracking this issue closely through our WD Forum and through our Technical Support hotline and the occurrence rate of this event has been very low. A specific set of conditions and timing sequences between the OS and the WD software utilities has to occur to cause this issue. Should this event occur, the data on the product can likely be recovered with a third party software utility if the customer stops using the device immediately after the OS X Mavericks (10.9) upgrade. WD will be issuing updated versions of these software applications that resolve this issue.
WD strongly urges our customers to uninstall these software applications before updating to OS X Mavericks (10.9), or delay upgrading until we provide an update to the applications. If you have already upgraded to Mavericks, WD recommends that you remove these applications and restart your computer. If you have already upgraded to Mavericks and are experiencing difficulty in accessing your external hard drive, please do not save anything to the drive, disconnect the drive from your computer, and contact Western Digital Customer Service at http://support.wdc.com/contact/.
There are reports of Western Digital and other external HDD products experiencing data loss when updating to Apple's OS X Mavericks (10.9). Western Digital is urgently investigating these reports and the possible connection to the WD Drive Manager, WD Raid Manager and WD SmartWare software applications. Until the issue is understood and the cause identified, WD strongly urges our customers to uninstall these software applications on their systems before updating to OS X Mavericks (10.9), or delay upgrading. If you have already upgraded to Mavericks, WD recommends that you remove these applications and restart your computer. WD has removed these software applications from our web site solely as a precaution as we investigate this issue.
If you have already upgraded to Mavericks and are experiencing difficulty in accessing your external hard drive, please do not save anything to the drive, disconnect the drive from your computer, and contact Western Digital Customer Service at http://support.wdc.com/country/ for further assistance.

It happen to me as well, lost 2TB of data last year.
WD send my drive for data recover, the end result is prerry bad, only 200mb++ of references files, nothing can be use again. Complaint to WD support, no answer given.
Worst case is, the replacement drive act funny again, report & request for replace dive on 13 Aug, till now still pending for arrangement to pick up.

For me, All external HDD work fine on Mavericks with or without WD software (for a week).
*But the problem start after I turn-on Time Machine and start first backup after upgraded to Mavericks, all data 4 partitions on my external HDD(with Time Machine backup partition) wiped out and show itself as new one!
I think the killer is not WD software but The Time Machine on Mavericks + Mac extended journaled.
Anyone can confirm that your problem start after Time Machine backup, and only the External HDD with Time Machine Backup? (or not?)

In my case I never used Time Machine, it is always turned off since it was introduced to OS X. It is for sure not Time Machine problem, at least not in my case.
I may be wrong, but based on other posts in this forumm and Apple Discussions forums the problem affects mostly large capacity WD Green drives with IntelliPower. Maybe the culprit is IntelliPower - reports of drives not going to sleep may support this. Just my 2 cents...
