Mavericks + WD MyBook - different behaviour - can't access drive

Hi,

I’m having problems with my MyBook RAID external hard drive 2x1TB / USB. Like everyone else I updated to Mavericks recently and now, I can not access my My Book.

Here’s the series of events that appear not the same as everyone else, but still, I am not without a resiliient back up solution.

  1. pre Mavericks my WD MyBook stored ‘archived data’ of great importance whilst day to day data was stored on my Mid-2011 iMac.

  2. TimeMachine was paired to a DIY Seagate hardrive in a non-brand external enclosure. Never any issues.

  3. The day after Mavericks came out, I did the upgrade. All went well it appears!

  4. As I was running out of TimeMachine disc space on the Seagate drive, I copied all the data from my MyBook to the iMac 1TB hard drive.

  5. Next after verifying all my data was now on the iMac correctly I used Mavericks Disk Utility to format the MyBook to Encrypted and Journaled.

  6. I set the MyBook as my TimeMachine then after checking it started, I left it to do it’s thing. (Backing up around 800Gb of data)

  7. Several hours later I came back to find the MyBook disc(s) chattering quietly and not a great deal of back up had happened.

  8. Some hours later I came back again to find that the drive had gotten very hot despite being in a ventilated area.

  9. Still not completed back up the drive was now making a great deal of noise and right in front of my eyes it disconnected itself from the iMac. (The usual message about disconnectecting a drive without ejecting came up.)

  10. I left the drive to cool down and now when I plug it in it is not recognised by my computer.

  11. I have no back up solution as all threads are suggesting the removal of all WD software (that I believe I have done) and not to plug in RAID devices until such times as WD come up with a solution. I do not wish to use this drive in case it causes any more problems and I REALLY need to know what to purchase instead even as a temporary solution as my business computer is at risk now because of this problem.

I’ve numbered each of the points to make it easier to ask questions.

Hi OnlineDood, can you share the model number for your drive?
