Western Digital has emailed customers warning them about possible data loss when connecting external hard drives to Macs with OS X Mavericks installed.

The MacRumors 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.

Sincerely,
Western Digital
Most of the complaints seem to center around Western Digital drives, but the company does say other drives could have issues as well.

Thanks Jackie!

I guess I'm glad that I've never, ever, used HDD manufacturer software before. I've always let the OS (OS X and Windows) manage the drives.

Good thing I don't use that software. Use my WD as my time machine backup and haven't had any problems at all.

So this is only happens if you use their software on Mavericks to access the hard drives?

So not a Mavericks flaw but WD's? Or maybe both, but because WD writes software for the Mac, they should've been accessing developer builds of Mavericks and would've found this out long ago.

Looks like WD didn't even bother to test their software before Mavericks shipped.

My experience has been strange. I manage 2 macs in my household and both are backed up to two WD passport drives. One drive worked fine after 10.9 but the other backup drive refuses to mount on one of the computers. Neither computer, 2011 and 2012 MBPs respectively, have any WD software on them.

I had some issues with a passport as well. It wouldn't mount, and disk utility said it needed repair. But it ended up mounting after some unplugging and plugging it back in. Really strange behavior. My Toshiba drive works fine though.

This is why you "nuke' all that crapware that WD, Seagate includes on their drives before using them. Then, throw the box away.

The moral: Don't use ****** useless bundled hardrive software.

Wait, people actually install and use the crapware that comes with their hard drives?

I've learned to make sure all my external drives are physically disconnected when I do an OS upgrade. Years ago, I was doing a point release update to OS X(Panther, I think), and the external drive I had all my FCP digitized video on was nuked as a direct result of that update. I spent lots of time and money trying to recover that data, but no go. 45GB of digitized video was lost, and I had to re-import all of it. I missed a deadline and a client was very unhappy. Painful lesson learned.

Needless to say, I never use WD's software, and I make sure all my external media is physically disconnected when I do an update. That said, Mavericks hasn't given me any issues along those lines.

Ah, that's how I lost all my porn LOL

Seriously, I had an external drive that I REMOVED the physical HD and was using it in a doc... guess what happened... EXACTLY what's been going on, that drive (originally from a WD MyBook, or whatever) mounted as MyBook and everything was lost!

argh.

How do you totally uninstall or burn WD Drive Manager? :mad:

This is why, when you buy a hard drive, ALWAYS format it to erase any crapware installed on it by companies who should not be writing software. I imagine your WD drives should be fine if you don't run any WD software. Let the OS handle hard drives, not some crapware.

i can't stand harddrives that come with software and data managers pre-installed. in some cases you can't even completely reformat since they have some proprietary partition scheme set up
