Western Digital has emailed customers warning them about possible data loss when connecting external hard drives to Macs with OS X Mavericks installed.
Forums, Western Digital's forums
, and Apple's Support Communities
all have threads about lost data after connecting Western Digital external hard drives to computers after updating to Mavericks.
In an email to customers, Western Digital warned about using its WD Drive Manager, WD Raid Manager, and WD SmartWare software products with Mavericks and suggests customers uninstall those applications before upgrading to Mavericks, or, if they already have upgraded, to uninstall those applications immediately.
Dear WD Registered Customer,
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.
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.
Most of the complaints seem to center around Western Digital drives, but the company does say other drives could have issues as well.
