Mybook studio raid 0, empty after installing Mavericks

Wow, PlotinusV, it must be heart-rending to you not to be able to reproduce the phenomenon, what with such a hardware potential in use and all.

As for myself, I am greatly interested in this generic disaster ( as I am always in every generic Mac disaster a.o.), but having no Mavericks compatible hardware as yet, have to stick to conjecture, past experience, reading and text analysis only, sorry.

Having warned my people on intermactivity.be as well as our Canadian nephews on ehmac.ca, I feel I can do no more. And of all those forum members, I've yet to see a similar HDD malfunction. Weird.

Only MacRumors and Apple Discussions seem to be on alert. Just to show this issue does seem widespread, but not pandemic.

Keep up the good work.

In dark is right... But the more questions we ask the more info we get... hopefully!

Or if we just postulate different possibilities. Such as; what if it's the code changes in Mail that happen to be messing up the Google Mail interaction AND the code changes in Safari that changed the way it works with RAM allocation AND then a couple of innocent bugs, which separately don't cause any major problems BUT when mixed together don't play nice with each other, and one or both of the types of disk formatting which doesn't play nice with some 3rd party software ingredient , ETC. "The Cascade Effect".

It feels like there's more than one ingredient in the mix. But Mavericks seems to have set it off.

Think about how mixing flour and water and salt are sort of benign but add yeast or baking soda or vinegar and wham a whole different experience.

The most common factor (ingredient) is Mavericks code changes. Those who didn’t upgrade haven’t reported any of the hard drive issues.

Yes, I am seemingly all over the map… but if we don’t think outside the box we are doomed to be stuck in the box.

I hope it is just a few lines of code in Mavericks that is not playing nice with a few other pieces of code but since I don’t have access to the source code I can only try to see this from as many sides as I can to try to understand what I can do to avoid experiencing these same problems other than not upgrading.

Well, now it's back to the beginning to see if I've missed anything in the many pages of posts that have been generated since October 24.

PS: If there any Apple generated comments or Articles I've missed please don't hesitate to reply.

I also lost all my data, I can't imagine how upset someone earning a living with external drives must be. That's video editors for example.

How can it come to situations like that? Why didn't WD test their software + HDDs from the very first day of Mavericks beta?

I also posted in the other topic, but in general:

When I wipe all the WD software, is using Mavericks safe then? Has anyone actually tested it?

Btw the only software to really recover your files is Data Rescue 3. Really.

Feel free to ask about anything else.

In the compilation of all variables regarding external HD corruption for purpose of process elimination "WD software, RAID, bridge connection, firmware etc." ..

...the variables given these corruptions on 10.9 have been far too random to fall within a logical statistical pattern, leaving..

➕there has been NO due consideration in these two threads to Mac computer model and year of mfg.

while Mavericks is the introductory nexus for the corruption,... examination of peripherals and WD software / RAID control has yielded no clarity......dare I say almost "none whatsoever"

Hardware build differences may expediently reveal causation stemming from Mavericks install.

If additionally people can add information such as:

"Macbook Pro 2008"...... or "Imac 2009" etc. to aid in deduction of a clear chain of causation.

Intel vs. not-Intel,...and Mac hardware information (model and build year) is a glaring omission in these postings.

Peace 😊

Good morning everybody,

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?

This is weird. All “empty” drives appear as having been formated with GPT (GUID Partition Table) partition map types. Which I’m pretty sure I didn’t do, but then, I can’t verify anymore as the affected drives are, well, affected.

Are you Cloning or Time Machining?

Both – Time Machine on a FW800 drive (non-RAID), regular clones of both the MyBook data vault and the system drive on stacks of USB harddrives (also non-RAID).

To answer hexdiy’s question – only one of the affected drives ever was used as a Time Machine drive – the, well, Time Machine drive, which since yesterday also appears “empty” and is called “MyBook” even though it’s a Toshiba drive in a LMB external enclosure. The MyBook was daisy-chained to it in the past, though.

Cheers,

-Sascha

Edit: Affected Mavericks Macs are one iMac12,1 (“Mid 2011”) and one MacBook Pro 6,2 (“Mid 2010”).

If you are a developer who lost data now is probably a good time to:

• submit a feature request to Apple to resurrect ZFS support
• support MacZFS and/or Zevo

Full data recovery should have been possible.

I have the same problem. I upgraded to Mavericks and after I have connected my 2x 6TB Mybook studio Firewire drives running in Raid 0, Mavericks renamed my drives and deleted my content!

I am running on a Macbook Pro 6.2.

Have tried to connect my drives to my iMac still running 10.8.4 but unfortunatley with the same result, empty drives!

This is a real nightmare! I am a professional photographer and have lost all my work! This is totaly unacceptable Apple! It's a shame that Apple is staying completly silent on the matter!

Please if anyone has a sollution post!

Not wishing to railroad the thread (which I think would be impossible anyway! 😁 ) - I too am hoping for a fast solution. I've started a new thread and for the benefit of us all, I am asking if their is any envirnmenmts that we know of that exist that have proved a safe back up solution?

A back up solution that hasn't been affected for example. - Apple's own Time Capsules are ok I assume? Check out my thread and post your known working solutions as I think it'd help lots of people who like me are pretty worried about losing their life long work.

@o.lahmar

Start recovering your data now using Data Rescue 3 (worth the money). You'll recover most of your work. 🙂

My LaCie NAS also kept its data – probably because it wasn’t physically connected to the Mac, but via Wifi.

My ad-iterim solution – I made a clean install of both affected Macs, cloned the remaining backup drives on a Mountain Lion Mac and played back the Data to the Mavericks Macs / media vault using said clones. Works so far, but then, I didn’t immediately lose data when upgrading to Mavericks either. Keeping fingers crossed.

A back up solution that hasn't been affected for example

Dont confuse a backup with an archive

safe data nexus:

1. Century disk archival DVD blank (pro grade JVC or otherwise

2. online or private website backup

3. Autonomous redundant isolated hard drives

Methodology to protect your data. Backups vs. Archives. Long-term data protection

😊

Thank you for the tips 🙂

So would it be safe to assume NAS drives and other WiFi storage is not affected by this problem and it is only physically attached storage? (I'm thinking no, as I trust neither WD or Apple right now)

Specifically, I am talking about an external hard drive that is storing a copy of my data to protect me in the case of an outage. Whether or not that is a TimeMachine version (preferred) or a raw data copy from the Mac, automate or otherwise.

I am looking for such a device that *has not* been affected by this problem to use at least in the interim that will allow the resilient back up of my data.

I don't believe I have confused an archive with a back up.

Good question. Seriously, I usually never upgrade to a x.0 version of a new OS, but I had to for a project which requires migrating to Mavericks ASAP.

Best bet right now, at least until Apple and/or Western Digital have a proper solution, is to stick with Mountain Lion. I’m VERY curious what the cause for this effect will turn out to be.

Yes, I know that, transfer data (not time machine) to a bare formatted docked or USB hard drive......then REMOVE IT, isolate it.

Ive tested a large pile of conventional simplex HD via bare docked and enclosure thru USB, all have worked fine.

This occurrence has nothing to do with HD Mfg. There are only 4 HD mfg. on earth, WD, Seagate, Toshiba and Hitachi

The only etched in stone rule is 1. Redundancy and 2. more redundancy

1. online archives

2. isolated HD NOT CONNECTED

3. archival DVD media

Any "storage nexus which can "FREEZE" data from ANY and ALL computer/connected manipulation"
