I have an external WD 1TB drive that was a time machine backup device. It was corrupted yesterday by Mavericks and the drive is now lost. Neither Drive Genius or Diskwarrior or Disk Utility could recover it. FWIW.

ugh..I have a couple of WD externals, so I think I'll hold off on going to Mavericks until I hear more about this. Maybe the issue is only the WD provided software - I would never use the software provided by the drive maker; stick to osx disk utility to partition/modify.
 
I just read this post right as I finished downloading Mavericks and am thinking of putting it off. I have two WD externals (one is a 500 GB Passport for my Time Machine from 2012 and the other is a 640 GB MyBook from around 2007 for miscellaneous files). I currently do not have the factory WD software installed on my mid-2011 MBP but I MAY have used it in the past when I had a Windows unit.

Do you guys happen to know if the problem is caused by currently having the WD software installed or if it can be caused by having used it in the past to do any kind of formatting to my drive? I apologize if this is an amateur question. I am fairly certain that I formatted the My Book drive for my MBP when I got it using the disk utility and then just copied the files back over to the My Book from another drive. Also, I am also pretty certain that neither of these drives are set to RAID (I guess I would know for a fact if they were :) )

Thanks,

Chris

I think problem occurs when you have the "wd drive manager" loaded.
 
I have a WD MyBook that I haven't connected yet and am now nervous to.

I really, really, doubt that I ever installed the software that came with the drive. *Why* do people install the software that comes with a new hard drive, anyway?

The reason I'm not 100% sure: Would these be drivers that came with the hard drive or anything else that I could have easily forgotten that I installed, or is this software that I would be seeing in my Applications folder or other obvious place?

The reason people install the software is to config the drive (set it to raid 1 or raid 0 which you can't do in disk utility because it sees the unit as one big drive)

I'm a dunce about this sort of thing and it's been a few years since I originally set up my WD drive. So I don't quite know what raid 1 or 0 are but I imagine I never had reason to set the drive up that way.
I might just wait a week or so to see if anything comes of this issue.
 
There's one thread over at Western digitals forum, and one thread at apple discussions. Beware, mavericks kills some external hard drives. Lots of people using WD mybook studio ll have had their drives reset and lost all data.

I've the the WD Mybook Studio II. I haven't lost any data, but the drive will no longer sleep. Not to be off-topic, but my external LaCie 2big won't sleep either. I'm using a 2012 iMac i7 with an Apple Thunderbolt to Firewire 800 adapter.
 
I have a Mybook Studio (version I) external hard drive. I just connected it without any problems, all data is still there.
I've noticed one thing though; when I eject the hard drive, it doesn't spin down. It only spins down now if I disconnect the FW cable.

Yeah, that indeed also seems to be a mavericks issue: fw drives not sleeping. Bummer.
 
It looks like WD's software resets RAID drives under Mavericks. At this point I would like to know if WD and Apple geniuses are working on ANY, ANY way of reversing what went wrong to bring the original volume back and if it's even possible. And yet they are still silent.

I never saw anything like this! It's just a hard drive for god's sake! It is unbelievable that my 5TB worth of data is gone without any warning! It is unbelievable that WD did not test their software on prerelease Mavericks! I still don't see any warning on both WD and Apple web sites!
 
At last I was contacted by someone at WD who wanted to know facts about what really happened. Hope they sort it out fast.
 
wild i use a 2tb wd portable drive for itunes for my macbook pro 13 and its fine and i use a mybook studio 2 and its fine as i use it for my itunes and i ve never let the drive sleep on my two computers
 
4 G-Tech drives, no problem. However, Mavericks does suck. This is Apple's Windows Vista. Had to install 3 times before it recognized my keyboard.
 
no problems with my 2TB MyBook Studio.......runs like normal just doesn't go to sleep when the computer does...:(
 
ive set my drives and its been that way since snow leopard to never sleep and i ve got my mybook studio 2 as firewire i wonder if its the sleep setting that may be causing the issues luckly i ve got a seperate backup as those 2 hd are for itunes
 
I have 500GB, 3TB, and 4TB Western Digital external drives. Been running them under 10.9 since DP 3. No problems here.
 
This just happened to me.

I had three drives with FW daisy chained.

MBP > MySTudio Raid 1 > MyStudio 3tb single > Oyen digital 2.5 enclosure.


ALL THREE CORRUPTED and now shows as empty hard drives.

omg, i don't know what to do. please help someone.
 
I've got a WD green drive in an OWC Neptune enclosure. Would this be ok to plug in and turn on? It seems like it's just the RAID and mybook products here...
 
Like I said, you need the "wd drive manager" to config the mybook studio ll units… once you set the drive to the raid mode you want - you can uninstall the drive manager.

Just one of the reasons I would never touch a WD external drive.

And oh yea, if that $2 plastic drive case breaks, try taking the drive out to use in another case - you can't because it doesnt have a SATA connection on it.

I have two WD External Hard Drives. 1st is a 320GB Passport and at least almost 5 years old. I formatted to FAT32 to make it compatible with my Mac. It also contains my entire iTunes Library that i've built up for the past 10 years. 2nd is a 1TB Passport which is barely a year and half old. It's partition into 2 drives. 1 for Storage and the other for Time Machine. I don't think i've ran the software on it when i first got it. Instead i just backed up whatever it had in it then ran Disk Utility to clean the drive then did the partition after.

My question is, Will i get affected even though i've formatted both disk and never ran the software that it came with? I'm luckily still on Mountain Lion and been holding back on the update/move to Mavericks due to app incompatibility issues and this issue.
 
No one can be sure, but it appears that unless you use the WD software, you should be ok.

Let me also highly recommend that you back up your external drive as well. If the 320gb passport holds your itunes library and is not backed up, you're risking losing all your music/videos.

I have a Drobo mini for my main offline storage, and use Carbon Copy Cloner to clone that onto my WD passport drive. Its sole use is to back up my drobo and keep a cloned image of my internal drive (I have 2 partitions on the WD).

I have taken a wd 1 tb drive out of the casing and put it in a dock...no problems?
