Nov 2, 2013 12:36 AM in response to troutmouthby keith contarino,Am I to understand from this that since there are only 4 manufacturers of external HD per PV, that two of them are not to be used with Mavericks? WD and Seagate (which manufacturs Lacie?).
At this point it seems, to me anyway, it's possible that ALL external HD may have problems with Mavericks. Maybe I'm being paranoid but no way I'm upgrading from 10.6.8 for a minimum of 6 months and see what other catastrophes occur.
This is getting to be like the bad old days with Windows when it would take months and months for Microsoft to fix problem after problem. Seems since Apple released Lion there have been more problems than with all the OS previously released combined

Nov 2, 2013 7:16 AM in response to Adriano Cisottoby panosmitsios,Mike h describes the best of my loss:
If you have experienced data loss with the following criteria then please open support cases with both Western Digital and Apple support:
- MacOS Mavericks 10.9
- WD Drive Manager / Raid Manager software installed
- data loss after a restart
- drives initialised to a single MyBook partition with exposed EFI partition
- loss of all existing partitions and directory structures
If you are an Apple developer then please report an issue with Apple Bug Reporter.

Where's the best place to log a issue with Apple. I tried going through Support, but they indicated i would have to pay for a case to be looked at?

Nov 2, 2013 10:00 AM in response to Mac in Mexicoby Pegasus2_Promise,Mac in Mex. I can't help myself but to wonder if there is any data structure left in the volume.
you can check with this tool:
Download rstudio demo for mac (demo version is free).
It will install on your local disk. This tool is read only and will not write to
your affected volumes. Once you run the tool it will allow you to scan the affected volumes.
Once its done scanning it will allow you to browse the volume content. Assuming the data area was not overwritten it should allow you to find your directories and files.. After that you can back up the content.
Good luck! Hope everyone on this forum recovers the data..

Nov 2, 2013 10:21 AM in response to Trocafishby jsac88,Just talked to AppleCare team and was told in not so many words that this is not Apple's problem, but that it needs to be fixed by WD. Unbelievable.

Much as we like to use this forum to take shots at Apple, in this case Apple may just be right. Other drive manufacturers are not experiencing the same failure rate as WD - at least as far as OSX 10.9 is concerned. I think we may assume that just about any WD drive that comes with bundled utility software should be considered NOT compatible with OSX 10.9 and should not be used.
It is really up to WD to notify registered users of WD drives of the situation and the remedies that should be taken. (Which makes me wonder - I have not received even one notice from WD even though I have two of their drives that up to now have been attached to my iMac).

Nov 2, 2013 11:18 AM in response to Trocafishby JJCMA,My two seagate GoFlex Firewire drives were not recognized by Mavericks. One used for Time Machine just "came back" on its own. If I had followed disk utilty I would have attemped to reformat the drive. I just waited and eventually unmounted and remounted the drive and all has been well
My 2nd Seagate Goflex drive did requie minor disk repair without any data loss.
Like most things I do not think it is the complete fault of WD or Apple. Hate to say it I would hold Apple more responsible, you would think they would have done more testing for compatability. Very odd that things fail as soon as Mavericks is installed.

Nov 2, 2013 12:26 PM in response to JJCMAby Tom in London,Don't worry too much, folks: you haven't lost your data. According to the article I've just read, your data isn't actually gone, it's just not being accurately reported to the OS. Read this.

Nov 2, 2013 1:05 PM in response to Tom in Londonby PlotinusVeritas,Tomshardware is a great site, but that article A: offers no genuine information / help, and is B: half correct.
Tomshardware
"To what I'm sure will be the relief of many, the data isn't actually gone, it's just not being accurately reported to the OS."
Several indications from skilled retrieval processes indicate (roughly 15% from best estimation) even with multiple recovery methods taken, data is not merely corrupted but absent (chain of this specific causation is yet indeterminate).
Additionally, in every case seen so far of data corruption,... most if not all meta data has been lost; which of course means "all the papers are there, but they've been dropped out of their named folders, and missing names"; ....making sorting 10s of 1000s of files very difficult.
Peace

Nov 2, 2013 1:56 PM in response to Bruce in Indyby Bruce in Indy,I bit the bullet and restored my 10.8.5 system from Time Machine. After doing some more investigation under Disk Utility, I finally installed the Lacie RAID Monitor which showed that one of the disk in my older 2big arrays had failed. This should be under warranty, so hopefully it will be taken care of by LaCie.
I'm not convinced just yet that this is the end of the story and I don't plan on upgrading to 10.9 again until a minor update or two have been released. There's still some weirdness in how the good disks are showing up in Disk Utility...
Moral of the story: you'd better have a good backup and a good backup of the backup. If the array containing my Time Machine backups had gone south I would have been in a world of trouble. Time to sign-up for an online backup service, I think...
