Mavericks corrupts external hard drive

AKabas

WD RED disk has not been affected......I wonder if this could be a Red/Green WD problem as well as a RAID problem.

Green - Eco friendly drives with design to be energy efficient and quiet. Designed to take advantage of non-use to lower power requirements. Base model consumer grade.

Blue - standard conventional HD

Red - Most common use is for NAS - designed to be compatible with NAS enclosures, does not utilize any ECO friendly power reduction, as the drive was designed to run 24/7 in a network environment.

Black - This is the most reliable, highest performing drive in the series and used in server farms etc.

Outside of some minor mechanical characteristics, I cannot fathom a Green being a failure point over a Red

"Red is more power efficient, noise is slightly less, speed is slightly more, MTBF is higher, load cycles are doubled, Red also comes with "Active Balance" which is designed to reduce vibration"

I am also getting a call from a specialist at WD, tomorrow I guess (since it's midnight soon here in Sweden).

They are apperently looking in to the issue according to this thread: http://community.wd.com/t5/External-Drives-for-Mac/All-data-gone-on-My-Book-Stud io-II/td-p/602387/highlight/true/page/5

Nice to see that something is happning. It would be nice with an response from Apple as well. It is so frustrating not knowing what is going on. If I hadn't backuped my photos I would be furious right now. The data loss I experience right now really ***** but life goes on (until I remember something irreplacable which is gone). The most frustrating thing is to not know if I should try to recover some data now or how long I should wait before a possible real solution or explaination, at least an answer what happened.

I'm another ****** off 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?

Thanks.

Not sure if this is related but I'm having issues with a G-tech Thunderbolt drive

once corruption has occured, resolution cant backtrack the corruption.

Hooking affected drives to another OS is still showing corruption and loss of metadata

sorry about your loss. Peace 😊

I have tried Disk Warrior. No success.

Fascinating things happend out there ... I have 3 "MyBook Studio II" with 2TB each, set to Raid 1 and in a DaisyChain on a FW800 Port on my iMac. I also have the "WD Drive Manager 2.2.6" installed. Everything´s fine with my data, but the drives won't go to hibernate anymore since i updated to Mavericks. They run continuously (since Mavericks released) ...

No idea how I can change this, but it's better to have no hibernate-mode than no data :-/

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.

@Dextera -- be safe and shut down your machine and disconnect those drives until an update from Apple or WD addresses this issue. My "MyBook Studio II" was fine for 3-4 days before it went GONE. Better safe than sorry -- don't risk your drives if you don't have to.

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.

thank you for deleting my post. but it does not solve my 3 empty WD disks? any help?

once corruption occurs, data recovery is the option
