This is aggravating....I've got 3TB of data (backups and media) on 2 separate WD Drives (firewire and usb3 - both MyPassport Studios). I haven't updated to Mavericks yet on my iMac (where the drives are connected), however, was going out to purchase another WD 2tb drive today to migrate some stuff over to and also use to backup my rMBP that IS on Mavericks. Now i'm afraid to even use my rMBP to access the data on those drives until this is sorted out. Luckily I have all this backed up to Crashplan...but still dont want the hassle of restoring from them if not necessary. I dont use the WD software and the drives have been wiped/reformatted since. However.....the WD software is installed on my iMac. I want to remove it....but who knows, that could corrupt it too?

I was going to hook the new drive up to my AEBS, has anyone been impacted by that method?
 
I have 3 WD external HDD's, one is used for CCC backups, the others are connected to my APX as cloud storage. I didn't have any issues using them before, but I also never ever use the included software.
 
I have a bevy of WD disks (not necessarily happy with that).

The thing that drives me insane about WD was the bundling of the software on the HD itself, on an untouchable partition. I've never used it, never even opened it up out of curiosity. Lucky thing, apparently. Using MacOS RAID on these puppies, works great. No problem in Mavericks at all (knock on wood), 12 disks in all.

I am wondering if Mavericks is getting confused by the partition map and just not seeing the user portion if the WD software is being used.
 
Mine went down yesterday...

WD RAID MyBook, everything gone, trying to recover it with Yodot recovery software and hoping for the best.

Was taking forever until I realised to turn off APP Nap and now I am making progress.

Now worried about using other external drives and they are on FW800
 
No problems with WD Mybook Duo Thuderbolt drives. (velociraptors)
 
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.

That's terrible. I would suggest not messing with them at all and just sending them to a professional.
 
Seem WD removed the wd drive manager from their web. Good thing. Hope someone there is working overtime.

It's probably still included with a lot of drives being sold in stores though, I hope they put a warning on their website.

happened to me too. It's not a wd drive, but it's corrupted and LOST!!!!

What type of drive is it and do you have any software for it installed?
 
It was a hdd included originally in my macbook. The enclosure is a generic one.

Happened already like a month ago also, while on the beta. Switching enclosure helped to fix the issue and be able to format the drive. I will try to do that fix again...
 
Are we really certain this is a Mavericks problem and not a WD problem?

I bought a WD weeks ago and ended up having to test it with Scannerz because it was acting flaky. The cable, which looked like it was made by elves was bad. I replaced it with a new cable, but my overall opinion of my 2TB MyBook is that it's basically junk and probably a bad design.

Why do I say this?

  1. In order to work properly, you **MUST** install WDs software which I guess resides in the HD. Without it the level indicators won't work, and FOR THE LOVE OF GOD, the power switch won't even work.
  2. The drive in my unit is some type of bizzaro world variable speed low power drive and the performance is crappy.
  3. I have not had one single problem with any of my other external drives, whether they be USB or FireWire.

The "requirement" that you load their drive management software just so you can turn the unit on and off is, as far as I'm concerned, just plain stupid.

WD used to be a good company. I'm afraid those days are over.

Likely a combination of the two.

Once I found that WD required their own software to fully "use" the drives (e.g., front label, usage bars, etc) I decided to never use it and to have Mac OS deal with the drives as normal.

Yeah, the indicators might be nice, but really there's nothing truly needed there.

They work fine when treated as regular disk drives.

To Lolito: that sounds like a failing drive.

Me too, I avoid installing any drive management software, it almost always causes issues.

With some older wd usb drives, they even included an extra "flash drive" partition that always mounted when the drive was connected, even if the hard drive was reformatted. That was the rare case in which you were forced to temporarily install their wdcrapware so you can disable it. After that I had to go into 5 places on osx and delete the wd software installed. (To my knowledge wd no longer has the separate "flash partition", my last drives from them didn't include it.)

Anyway, I installed mavericks before I read this post, so far no issues with 2 firewire wd drives (jbod Mac software raid, and 2 usb wd drives.)

Yeah, that's that untouchable partition I was talking about. PITA.

I found a workaround somewhere for them always mounting. It was long enough ago (3 years?) that I don't remember what it was, but if you search you might find it still.

I turned that stuff off a couple of years ago.

My solution was installing the crapware, then using the config to turn of the untouchable partition. After that I uninstalled the crapware, it scattered stuff all over the system if I remember.

If I had that issue again, I would install osx to a usb flash drive, use the usb flash drive to boot for and load the crapware to allow me to disable it. After simply go back to using the normal boot drive now that the wd drive was fixed.
 
I have a WD Elements 2TB which is working fine with Mavericks.

From what I read on the web, the Mybook/Mystudio series are less reliable. The same goes for certain Seagate series by the way.
 
I removed WD folders from Library/Application Support and all files with WD in their names from System/Library/Extensions. Finally the WD Drive Manager does not show up in the menu when I connect the formatted MyBook Studio Ed II 6TB.

BTW my Time Machine is on a 2TB single hard disk WD My Book drive and it's working fine under Mavericks with and without the WD software. Somebody in the WD forum said that his WD RED disk has not been affected but his WD GREEN disk on the same dock has been formatted to "MyBook". I wonder if this could be a Red/Green problem as well as a RAID problem.
 
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.
 
hem it seems according to tom is that if you use the drives management software it can mess the drive up only thing i use to format the drives with is disk utility the mybook studio 2 only thing wd i use with it software wise is the raid software setup and condition program the only time i have used the wd drive management software was on lion when i got some wd drives to remove that pesky program stuff
 
That seems to fit with the Pegasus issue during the beta period.

As I mentioned I'm running my Drobo Mini (using their proprietary RAID implementation) with Mavericks and so far no issues.

Where did you buy your drobo?
