Western Digital External Hard Drives Experiencing Data Loss On OS X Mavericks
Western Digital has been emailing customers and warning them about hard drives “experiencing data loss when updating to Apple’s OS X Mavericks.” The problem seems to effect multiple kinds of drives, including the company’s popular MyBook lineup.
According to Western Digital, the incompatibility with Mavericks isn’t a hardware-level issue, but something to do with the software that is shipped with the drives it sells.
The WD Drive Manager, WD Raid Manager, and WD SmartWare apps all seem to be causing data corruption in Mavericks. Support threads on both the Western Digital and Apple support site are filled with complaints of corrupted drives after updating to the newest Mac OS.
