Dear WD Registered Customer,

UPDATE: November 1st, 2013

As a valued WD customer we want to make you aware of new reports of
Western Digital and other external HDD products experiencing data loss
when updating to Apple's OS X Mavericks (10.9). WD 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 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. 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.wd.com/country/ for further
assistance.

The WD Drive Manager, WD Raid Manager, and WD SmartWare software
applications are not new and have been available from WD for many
years. However, solely as a precaution WD has removed these
applications from our website as we investigate this issue.
