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
different enclosure/ Sata bridge, but swap identical HDD controller boards
Yes, in repairing bad HD control boards, if you have stacks of the same HD,.. easy enough to do and done so a few times.
Swapping SATA bridge cards is easy enough, but upon any data corruption, most anyone here doesnt know how to swap HD controller boards NOR has the spare identical HD to cannibalize them in "testing".
Nor do most want or dare removed a HD from its enclosure which is often sealed plastic clamshell you have to break and crack to get open.
I'm curious about your last question. I've been asking myself the same thing. I'm currently running on a 2013 iMac that I upgraded literally out of the box and built from the ground up with no migrations from any existing system or backup, all new software installs (no WD or other HDD or RAID driver installs, RAID configuration on the DataTale is done via a web interface hosted on the enclosure's firmware). My DataTale RAID was built and formatted on this machine and hasn't been on any other. I've transferred around 1.6TB of data (over 100K files) over the course of two days now. If I encounter any corruption, I'll report here immediately. I've got backups of the files that I transferred to the RAID stored on-site and disconnected. Keeping my fingers crossed right now.

And yes, a WD MyBook was daisy-chained to the Time Machine drive previously.
The drives I tested were all non-RAID, run-off-the-mill USB drives by Toshiba and Hitachi.
Since your posts had fragmented information here and there,.. I didnt see it until now.
The collective totality of your posts important information... (if it is actually true that you got all WD software off, but honestly,...new locations still are manifesting where its being found at) ...points to possible WD MyBook firmware corrupting other drives WHILE your Mac is connected to the WD MyBooks, but also ..(? you didnt indicate if the Toshiba + Hitachi were connected at the SAME TIME the MyBooks were connected)
1. Mybook firmware cross 'contamination'
2. SATA hardware backwards corrupting other HD while connected at same time as MyBooks
3. remaining WD software still yet to be found (despite you being convinced its all removed)
4. hidden SATA drivers from WD MyBook populating to your "plain USB formatted" Toshiba and Hitachi while NOT connected at same time as MyBooks
BTW, has it occurred to anyone in this thread that there are no reports of newly bought, bare and unformatted drives being affected after mounting them in an external housing, and formatting/ partitioning via Disk Utility?
There are reports of same,.. Ive tried to duplicate it with many drives with no "luck" in doing so.

I also tested it on my second Mavericks Mac, a Macbook Pro which was never, ever, connected to a WD drive, at all. It, too, hoses external drives once connected. I don’t know since when it does that, as I never needed to connect an external drive to said Macbook Pro and only did so today, for testing purposes.
I make backups from the MyBook on a stack of USB HDD every first of each month. I did so two days ago, it worked flawlessly. I actually pulled images off said backup yesterday on the Macbook Pro that never, ever, had contact to a MyBook, and to my main iMac. I connected this very backup drive today to a Mavericks Mac, and it appears empty.
I don’t have the foggiest what’s going on here, this behaviour hasn’t appeared in one week of Mavericks on both affected computers. Since of today, it does. I haven’t installed any software updates since yesterday, and there haven’t been any power surges (my first guess). I can connect one of the remaining HDD from the backup stack to my Lion or Snow Leopard Macs just well, once I connect them to one of the Mavericks Macs, they appear empty on those Macs, too. And WD doesn’t seem to be involved, as, well, the Macbook Pro never had any dealings with WD since I got it, and there’s no software remains on the iMac, either.
I also tested it on my second Mavericks Mac,.... I don’t know since when it does that
What is "it" ?
You "dont know" regarding what?
As per the HD connected to the macbook Pro "never connected to a WD drive",......what are they, ...make,.. model,.. formatting,...connection bridge (usb/firewire/thunderbolt)
~~hasn’t appeared in one week of Mavericks on both affected computers
What variable was introduced at "one week from upgrade"?
😊
“I don’t know since when” the Macbook Pro also hoses my external drives. The iMac worked flawlessly yesterday. Today, empty drives. And today, also empty drives on the Macbook Pro when I connect one of the backup disks.
Affected drives include Hitachi, Toshiba, WD, and Seagate, FireWire as well as USB. Only the WD is in a RAID configuration. No matter what sort of drive I connect to one of my two Mavericks Macs, it gets hosed and can’t be read on Snow Leopard, Lion, or Mountain Lion afterwards. Yes, I have five Macs here, since I write books about Mac software.
There was no variable other than “having external drives connected” during said week – the iMac has/had a FireWire800 Time Machine HDD connected all the time, plus the WD MyBook as a data vault. The Macbook Pro hadn’t either.
The propblem literally appeared over night, hence my first guess at power surge. But backup HDD I made two days ago, with all data verified, now appear as “empty” too once connected to one of my two Mavericks Macs.

I suspect sleep/ wake events (and the remount/ spinup of disks) are more likley than a power surge, unless you know that you have very bad mains supply?
Power surges would affect more than just your Macs.
Sleep events might be the ticket. Both Mavericks Macs can’t be put to sleep properly anymore; the iMac wakes up 10s afterwards, the Macbook Pro only goes to sleep when closing the shell, not when using the menu item.
What still irks me – why didn’t I have any issues the week before? Is there some sort of buffer overrun in place, Spotlight or Versions perhaps?
My imac is a 2011 27" 3.4 ghz i7 i lost two external drives of info.
Reading all threads noticed bigd-pdx has 2013 imac and says he hasn't lost and info and Don Hayes who works on macs says he doesn't have problem either; has he got 2013 macs as well???
Many of you mention that your connected external drive shows up "empty". When you say this, do you mean when you querry your drive, it says 0 bytes used or is it you just don't see any files when you open the drive? I ask this because when this first happened to me, I didn't look at the numbers, i just saw there were no files showing up. Then I noticed my 1 TB drive said i had 45GB available and 950GB used. That's when I decided to go to Disk Utility and run Verify. After that I could see the files and Time Machine began working again.
On another note: Maverics changed the name of my drive from OWC to OEM, but left the mounted partition name the same as it was.
My first Mavericks install was on a Mac Pro 4,1 (2009) with 3 internal drives in the trays, 1 SSD on the second DVD Drive channel, 2 FW 800 Western Digital 1TB drives. I didn't suffer any issues with that system and the two WD FW800 drives are intact and functioning as normal as of today, the last time they were mounted.
Worth noting, that the Mac Pro system was an in place upgrade to a very mature install of OS X that had been through two previous OS upgrades and had numerous software installs with low level drivers (none of which were WD or HDD drivers of any kind that I'm aware of).
Also, just so we have as much information up here as possible in an effort to determine root cause:
2013 iMac: Upgraded out of box.
2013 MBA: Upgraded after about 2 months of light use.
Another WD drive that I forgot to mention. 1TB My Passport USB 3.0. It's been mounted on all three of these machines (including the Mac Pro) while they were running Mavericks and is presently still intact.

To everyone reporting data loss it would really help if you could provide the following:
You can find your mac model number using Apple menu > About This Mac > More Info... button under Hardware Overview: Model Identifier.
Mid 2011 and Late 2012 iMacs
So nggalai, are you saying that your external HDs are APT (Apple Partition Table) formatted?
Please go to: About This Mac / More Info / System Report / Hardware / Firewire... look for Partition Map Type:
What does it say the Partition Map Type is?
I'm wondering if there are more problems with GPT (GUID Partition Table) and less or NO problems with APT (Apple Partition Table) formatting, at least for Time Machine backup drives which don't need GUID.
If in fact it's more of a Partitioning Table issue it might mean that an update from Apple may fix the problem.
Are you Cloning or Time Machining?
And to everyone:
What about RAID vs. non-RAID setups?
GUID and RAID?... More problems or Less?
GUID and non-RAID?... More problems or Less?
APT and RAID?... More problems or Less?
APT and non-RAID?... More problems or Less?
We're shooting in the dark out here, niteowl. That's all we can do, obviously. And nice try at that.
But another shot: has any of the unaffected drives not been used to contain Time Machine backups, now or in the past?
Why do I ask? TM backups are not bootable, and the presence of the phantom EFI partitions on the affected drives seem to indicate that Mavericks tries to make them bootable.
Just to make sure: are any bootable drives affected at all ( I seem to have read about some, but this is such a long hread...)?
Yeah, long shot, I know: APM partitioned drives being affected less than GUID partitioned ones seems to indicate the exact opposite. Just thinking out loud...
And something else: has any of the drives affected been driven with Mavericks' AppNap switched off? Sleep does seem an issue here, hence maybe the week-long delay of infection/ malfunction.
Sorry, just my 2 cents.
hexdiy has any of the unaffected drives not been used to contain Time Machine backups.....are any bootable drives affected at all
Ive tested time machine backups (and still am testing on 2 drives) on a Mac Mini and Macbook Pro running Mavericks.
Ive tested 2 bootable HD clones on a pair of 1TB Toshiba drives in a HD dock and one in a USB enclosure.
One was a boot clone of a macbook Pro and another from a Mac Mini.
No occurances on any of the drives, encompassing Hitachi, Toshiba, both TM backups, non-backup drives and 2 boot clones.
