As a rule I never upgrade to a new OS untill all the bugs are sorted. The first issues of new operating systems are are usually bug ridden.

If it only happens with WD drives I think it's something you should look into. I have other external drives behaving like they should.

It's got to be a bug new OS, if your drive worked in Apples older OS. The only thing you've changed is the OS. Therefore it must be the OS.
You need to inform Apple that their new OS is not recognising your DW drive.

Same thing happened to me with a WD My Book Studio Edition II 6TB. After calling WD numerous times they gave up and asked me to ask Apple what Mavericks does to their raid drive and to try recovering my data with a recovery software. 5TB archive gone at the moment, with a partial backup. I've never seen anything like this. Very serious and desperate situation.

I don't claim to be any expert but my guess is that Apple's (software?) RAID took over and reconfigured the RAID. WD Drive Manager is obviously imcompatible with Mavericks as it appears multiple times in the menu bar everytime the drive is mounted and does not go away without a restart. The Empty/"MyBook" state of the drive is stuck no matter where I tried it (OS 10.8 and 10.6 with and without WD software).
I chatted with a higher level Apple tech support and sent him links to these discussions: https://discussions.apple.com/thread/5475136?start
I'm holding my breath waiting for a solution from Apple and/or WD where my old volume and data will magically reappear.

Im having the problem with myPassport. MyBook with my backup works fine but MyPassport does not show up in finder. I have alot of files on there that i need. If you find out anything let me know. I am currently trying data rescue 3 so hopefully that works.
