The problem

I bought brand new WD Caviar Green disks and put them into My Book World Edition II White Light case but… surprisingly it doesn’t work or even start! Only top LED is blinking/flashing and MBWE doesn’t appear in my network environment! Similar situation is with WD My Book World Edition I White Light or with my previously working disk that stopped working.

How to recover bricked WD My Book World Edition White Light or install/replace brand new disk(s)?

Also following questions will find here their answers:

• Which disk to buy for WD My Book World Edition White Light?
• How to increase/upgrade WD My Book World Edition White Light capacity to 3TB (MBWE I) or 6TB (MBWE II)?
• How to downgrade WD My Book World Edition White Light firmware version?
• How to clean personal data (reset to the factory state) WD My Book World Edition White light in purpose of sale?

What’s going on?

If suddenly your MBWE stopped working, firstly decode your MBWE situation by LEDs state/action and refer to the My Book World Edition User Manual on page 10 (LED Indicators). Maybe nothing serious happened there but only something unusual.

Anyway, MBWE is booting from NAS OS written on disk, so you can’t start MBWE:

• with brand new clean disk(s) or
• when your current disk(s) has broken boot partition or master boot record (MBR).

There is no user procedure provided by Western Digital to repair MBWE or start brand new disks. You can only return complete MBWE (with disk(s)) to Western Digital to recieve new one, if you have void warranty (for warranty conditions see: support.wdc.com).

I couldn’t agree with this, so I’ve decided to make it my own and here it is…

What’s this?

This is linux bash script solution to restore MBWE White Light (install firmware once again) with a FACTORY STATE and CLEAN DISK:

• Works with both MBWE White Light (I and II) with any size of disk (even 3TB HDD)! but only WD Caviar Green!
  Be aware also that not all WD Caviar Green drives may be MBWE compatible! (see WARNING below for details).
  
• Designed to auto download & install always latest MBWE firmware directly from wdc.com (manually available here and fw revision info is here). But you can also install any firmware since & including ver. 01.02.06, that I’ve tested on 2011-04-20. If you encounter any problems with the latest version, pick ver. 01.02.06 and then upgrade to the latest firmware by MBWE interface any time you want.
• Full install takes 1 minute! excluding firmware download.
• In MBWE II only 1 disk needs to be prepared! – the second one (clean) will be adopted by MBWE itself.
• Config with only 4 lines to adjust: disk label, serial number, model type, MAC address.
• 1 script to fire! and little wizard will guide you.

WARNING !!!

This solution WILL ERASE ALL YOUR DISK DATA, if you connect your old disk!!!

If you want to rescue data on bricked MBWE, contact Western Digital on wdc.custhelp.com or find handy crafted solution on mybookworld.wikidot.com. But, you can also boot Ubuntu from CD and try to make your data copy before this operation (4th partition is DataVolume partition) and move them back to your „new” MBWE. This should be possible if you got MBWE I or MBWE II with RAID 1 (mirror) or JBOT disk configuration. In other case, you shoudn’t do anything but call Western Digital if you care your data and you don’t know what to do.

Don’t buy new WD Caviar Green disk without being sure this model works with your MBWE!

As Western Digital online customer support says, Advanced Format Drives are not compatible with MBWE but they don’t say which one particularly is advanced/incompatible (more about Advanced Format Technology). Particular WD Caviar Green disk models with MBWE compatibility statuses are (for specs go to wdc.com or Specs Sheet):

• EADS, EAVS, EACS (SATA II 3Gb/s) are definitly compatible as WD says.
• EARS (SATA II 3Gb/s) are compatible as tested on my own and by the community.
• EARX (SATA III 6Gb/s) compatibility varies as community report successes (1 case) as well as failures (1 case). WD support hints it may or may not work due to relatively older MBWE SATA II interface. Try different jumper settings as a last hope (see pic).
• EZRX (SATA III 6Gb/s) is compatible as tested by the community (here is the proof of 2x3TB WD30EZRX).
• EADX, EZRSDTL (SATA III 6Gb/s) compatibility unknown yet.

REMEMBER: If you buy new disks to your MBWE II, always take both disks of the same type and the same part (production series) due to RAID performance and conformance. Therefore, you should buy both disks from the same retailer at once (at the same time).

Quick How-To

1. 1 Boot Ubuntu
   from CD/CDRW/PenDrive. How-To on: Download Ubuntu. (NOTICE: If you have problems with other linux distributions/versions simple use Ubuntu 10.10, because I’ve tested it).
2. 2 Wire your computer
   to the Internet (wireless connection is often not possible due to lack of many Ubuntu CD WiFi drivers and it’s not our goal to play with it here).
3. 3 Extract mbwe.tar.gz
   (right click and choose Extract Here) on Desktop (all files should be placed in folder mbwe – if not, correct this). If you pre-downloaded firmware image manually, place it in mbwe folder and rename it to fw.img.
4. 4 Connect your disk
   through USB (or any other hot plug way).
5. 5 Edit mbwe-config.sh file
   in folder mbwe and type your disk parameters (DISK_LABEL, MBWE_TYPE, MBWE_SERIAL and MAC_ADDRS) according comments.
6. 6 Open Terminal
   (CTRL+ALT+T) and type:
   cd Desktop/mbwe
   sudo bash ./mbwe-install.sh
7. 7 Listen carefully
   what is Terminal asking you and obey his commands. If you need some screenshot hints go to the Polish version.
8. 8 After Safe Remove disk
   using Disk Utility (click Safe Removal button), place it in MBWE bay (any bay in MBWE II). Remember to unplug MBWE from the wall (electricity) before.
9. 9 Plug MBWE to the wall
   and wait 3 minutes then go through first start procedure in MBWE web GUI (log in as admin/admin).
10. 10 For MBWE I that’s all.

For MBWE II go further:

1. 11 Shutdown MBWE
   by holding Power for 3 seconds and wait untill all LEDs are off, then unplug from the wall and put your second clean disk in an empty bay. If your second disk contains any data or structure (isn’t brand new), you must completely clean it before (unallocated space = no partitions, unformatted). This can be done using Disk Utility.
2. 12 Power MBWE on
   and voilà.

That’s all folks
