I have a 1 TB USB WD Mirror Edition raid drive on my iMac. It has a recurring problem of um-mounting and I have to power it off and on to get it to re-mount. This is a pain since my iTunes library is stored there. What could be the issue? The raid status is healthy... but yesterday iTunes took forever to play a video and I had to force quit iTunes a few times for it to finally work.

Also if I decided to get another raid drive can I just pop in the 2 drives I have in this one and have it work?

Did you try a different USB cable?

I changed the cable and the hard drive still unmounts and I have to cycle the power to get it to mount. I dont see any firmware updates for the drive so I am at a loss.

Stupid question but...is the power adapter also plugged in?

If you keep having problems, just RMA the drive with WD. Most of their external hard drives have a three-year warranty.

My issue with that drive is OSx sees the drive but iTunes doesn't. Not always but often enough I have to quit iTunes, unplug USB cable, plug back in and launch iTunes again.

That is exactly my problem. If I get a new raid enclosure can I just pop the drives in the new enclosure and iTunes will see it? Or do I have to buy one drive and rebuilt the raid from one of the drives from the WD enclosure. If I RMA it back to WD I will need to backup my 300+ gb of iTunes.

You can get an advance RMA, which means WD will ship you a new drive before you ship back the defective one.

Have you looked on WD's website to see if this is a known issue? There may be a firmware update for the drive that fixes your problem.

You can't pull the drives and put them in any enclosure. RAID setups are specific to the controller that handles the RAID; the only enclosure that would reliably be able to access your data without damaging anything is an identical WD enclosure.
