Hello, I am having an issue with my RAID. I have the 1TB version set up for RAID 1 which has been working for quite a whlle. Recently I have been experiencing a problem with writing to the drives. I use this device as storage for photographs and found that when I edit a file on the RAID it does not write properly. At first I thought it was not being written to at all, but discovered that it will eventually write the file, but it takes about five minutes. Obviously there is something wrong. I thought that updating the firmware might solve the problem, but the update is not working at all. I have done all the things that are called out in the instructions, i.e., nothing on the USB bus but the drive(s), keyboard and mouse. Everything is plugged directly into the computer, no hubs or such involved. What happens is that the firmware updater loads, sees the RAID, and begins the update process. As soon as the updater dismounts the drive (I know this is necessary) it shows an error that there is no drive found to update. There is nothing wrong with the cables, I’ve checked that. I do have the files backed up on another drive. Here is my system info:
iMac 27" 3.4 GHz i7 16GB ram
Mac OS 10.7.5
WDH2Q2000
What I see in the system logs is that the updater just doesn’t find the drive after it launches and the process crashes with a SIGBUS error. As for the write problem, I see lots of USB timeouts.
What to do next?
What’s the status for the drives under Drive Manager?
You might want to run a test on the unit to verify if either one of the disk is failing.
Try using a different interface cable if possible like Firewire or another USB.
Don’t think a firmware update is required with this scenario.

His disk isnt failing, Mavericks is corrupting RAID combined with the garbageware WD software HD controller
replying to this thread, since a WD staff has responded.
i have a 2tb (2x1tb) MyBook Studio FW800 drive. it has been formatted for RAID1 via the WD manager.
i have NOT mounted this drive since upgrading to OSX Mavericks.
the WD manager software was not loaded by the new OS, and was listed as incompatible. it appears that WD needs to update WD manager to work with Mavericks.
my question is this: since the drives are RAID1 mirrored, can i remove them from the enclosure and mount them using a dock or other enclosure? or has WD manager created it’s own file index on the disks that would still be unmountable by the new OS?
i really need to access the data on this external, but i don’t want to risk corrupting the data. i’d rather wait until WD and Apple can come up with a solution, but i am worried about the timeframe a fix, if any, will come in. please help
John, the Drive Manager status shows “healthy” for the RAID and “good” for both drives. Disk Utility finds no problems. I have used different cables, and it exhibits the same behavior whether on the USB or FW bus.
Thank you.
Guru,
Your rather snippy reply is off base and not how a true guru would speak. You didn’t look at the version of OS I am running. 10.7.5 is Lion. Mavericks is 10.9 and is known to brick this particular hardware RAID so I won’t be going there at this time.
Thanks for playing.

Bughouse,
Please do not hijack this thread! Your post is off-topic and is obviously confusing people.
Thank you.

Thank you.
Will need to suggest to contact support for additional troubleshooting.
Do not continue trying to update the firmware since it might damage the drive.
Please reply back once you get a resolution from support.
