After installing Mavericks, my WD My Book Studio II connected by firewire, does not contain any files. It is a raid 0, after using the operating system while I wonder if I could use time machine to which I said no.
In this hard drive I keep my most precious files.
Forgive the level of English, I'm Spanish and I write through a translator.
A greeting and thanks.
Mac mini (Mid 2011), OS X Mavericks (10.9), Raid 0
PlotinusVeritas, Western Digital has not stated this as the cause. Where did you get this mis-information?
Nggagli,
"...but I had to for a project which requires migrating to Mavericks ASAP."
Such as what? What could you not have accomplished with 10.8 that you're saying you needed 10.9 for?
Western Digital has not stated this as the cause.
I have made no claim of specific causation related or unrelated to any mechanical HD, ...WD or otherwise, you have misunderstood or misread something neither implied or otherwise.
Peace 😊
Had a long talk with Apple Support today. I made it clear that I'd tried the obvious things (like running Disc Utility) and was more interested in reporting the issue to the highest level, rather than being talked through basic steps.
They actually responded to that very well, and it was largely an information-gathering exercise. They said they'd had other reports like this. By the end of the call I was with a second-tier operator who really dug down and took lots of info, so I am pretty encouraged they really do want to get to the bottom of this. It's all been passed on to their "engineers". I'm expecting a call-back on Thursday. Overall, I'm pleased to have been very impressed with their response thus far.
The first operator did suggest one fascinating nugget of information -- that he had heard that some drives to which this kind of thing has happened have been left connected for a while, and the files have "reappeared"! Perhaps somebody would like to try for this on one of the test discs that have been mentioned. Meanwhile, Apple unsurprisingly agreed that it was probably wiser to leave my drive disconnected pending the results of the investigation.
Finally, since someone has asked for this, in my case it's an early 2009 MacBook, 5.1, that's involved.
"the cause of this issue is known...contact WD about a firmware update...or attach it to a mountain lion Mac for data retrieval...or last resort extract the HD from its enclosure for data extraction.."
Seems pretty clear to me :-)
Very initial reports were coming entirely from WD MyBook, upon which WD itself released a statement on its on board from the management this was related to it control software and to remove same.

LOL. Thanks!

I’m in the last stages of a Mac book. The publisher required I also include Mavericks (so the book stays current longer), incl. necessary screenshots and changes on the Apple application front. Bad timing. 😉
Interesting update here, including the email from Western Digital. http://www.infoworld.com/t/storage/os-x-mavericks-upgrade-destroys-data-reports- western-digital-230100 .
Mostly it consists of the same speculation that we have a lot of on this thread, while Apple's response to the crisis makes Rob Ford look forthcoming.
QUESTION RE RECOMMENDATION TO
UNINSTALL WD DRIVE MANAGER:
According to the My Book Studio II user manual the "WD Drive Manager enables Safe ShutdownTM" making sure that the drive can't be switched off during write operations. For example during or after a Time Machine backup you can hear the drive writing or defragmenting files. Switching the drive off in the middle of a write operation would result in damaged files. Now that WD recommends to uninstall WD Drive Manager - wouldn't that be dangerous? How should I know when is the correct = safe moment to switch off my drive?
Many thanks.
Just use basic disk handling…
Unmount BEFORE powering down.
Wait for disks to stop spinning after the unmount before moving the case.
If you are paranoid shutdown your computer or look at the status of Time Machine in the menu before removing the disk.
Time Machine tends to make disks operate at their noisiest levels - it's usually obvious when the disk is busy, especially if you are close enough to unplug it.
I'm not sure we require third party kernel level tools to replace basic common sense.
Hello,
I have the same problem LOST my data from My Book Studio II - THERE i had everything from my company - all documents.
Really this can't happen - they must come up with a sollution.
We did pay money for this in order to have secure data Raid0 (that was the ideea , not to loose any file) and now we lost all drive ???
As someone here said ...i wait that solution to make the data come back ... or this is bad.
Have a great day/night!!!
"Until Apple issues a workaround or patch, it would be very wise to avoid using any external hard drive, or any eSATA- or Thunderbolt-based peripherals, on Mavericks systems."
Here's an idea: DON'T UPGRADE TO MAVERICKS UNTIL APPLE GET'S IT TOGETHER.

...perhaps he is not as well-versed in All Things IT as you are.
He's here for assistance, not belittling inuendos.
Do you have backups?
