Flashing blue rings

The my book world has 3 different kinds of flashes.

1. Fast flashing (every 3 seconds) - Which means it's going into standby mode.

2. Slow flashing (every 5 seconds) - Which means it's in standby mode.

3. Alternative flashing between inner and outer ring - Means RAID failure (this only applies if you have the RAID compatible version [dual drive my book world])

4. Simultaneous flashing - Means the drive is overheating and the drive needs to be shut down.

Try resetting the drive, using the link below for guidance (this will not effect your data). If the drive does power-up, you will need to change the IP to static, if you had it that way before and you will need to login with the following login details: Username: admin | Password: 123456

Mine is the same. Powered down over Xmas. Powered it up and the disks spin up but no lights.
Emailed WD. They sent me a bunch of standard test stuff. Nothing helped.
I ended up taking the two 500G drives out and putting them in my computer. The first one I tried (B) would not allow the PC to start!!!
The second one I tried (A) was found correctly in the BIOS. The XP disk manager found it but couldn't identify the file format.
I put the A drive (only) back in, powered it up and voila ... it worked.
Looks like the B drive failed. Now to go buy a relacement drive for B!

Have you tried different cables or a different port on your router. Is there any way to get into the Hard Drive by connecting it directly to a PC and checking the network settings or anything..? If not, then you may have to connect it directly to a PC and share it to your other PC's.

I would try to connect the drive directly into an ide or a sata cable on the motherboard. Maybe using the western digital tools from their website you'll be able to access the data and copy it. I hope this helps you.

The Failed Mount issue is usually caused by Internet Security settings. The most common way to resolve it is to add the following files/ports to the exceptions list of your firewall(s) -- in some cases you will need to add it to the Windows Firewall, even if you have another Firewall installed as well:

MioNet.exe (C:\Program Files\MioNet\jvm\bin\MioNet.exe)
MioNetManager.exe (C:\Program Files\MioNet\MioNetManager.exe)
ServiceStatusGui.exe (C:\Program Files\MioNet\ServiceStatusGui.exe)

These ports are also required for MioNet to create a drive-letter for remote drives:
TCP In/Out 443
TCP In/Out 445

The issue you are experiencing is an error on our servers. Our next version of MioNet should prevent and resolve the issue, but in the meantime you must complete the following steps to regain remote access to your My Book World (blue rings):

To create a new MioNet account, please use the following instructions:

Part A. Reset MioNet/Anywhere Access

1. Please open your web browsers and enter (without the quotes) "http://<IP address of My Book World>" or "http://mybookworld" in the address bar. The Shared Storage Manager web page will appear. The username and password it requests will be the same as your MioNet username, and the original password used for MioNet (if you changed your password on our website, it does not update the My Book World).

2. Once you have accessed the Western Digital Shared Storage Manager please select "General Setup", then choose "WD Anywhere Access settings". On the following page you will have three buttons to select: please click on the "Stop" button, wait until WD Anywhere Access status goes to "Inactive", then click the "Reset" button. Once the WD Anywhere Access Status goes to "Not Registered," (on older firmware, it will go back to Active), the My Book World has been properly reset. This will return the MioNet software on the My Book World to default settings. It will not harm your stored files.

Part B. Uninstall and Reinstall MioNet (on a computer located on the same network as My Book World)

1. Uninstall MioNet from one of your computers.
2. Insert your Western Digital installation disk or download MioNet from http://www.mionet.com/mbvista and launch the MioNet installer.

NOTE: You must use the installation disk or the link above to create your new account. Certain functionality related to the My Book World is related to the installer you use to register a new MioNet account. Failure to use the proper installer may result in the need to repeat this process.

3. Register as a new user. You will need to specify a new username and E-Mail address.
4. During the installation, MioNet should detect the now reset My Book World. Please add it to your new account.

Part C. Uninstall and Reinstall MioNet on your other computers

1. Uninstall MioNet from your other computers.
2. Install MioNet using the Western Digital installation disk or downloaded from MioNet from http://www.mionet.com/mbvista and launch the MioNet installer.
3. Register as a current user with your new account's information.

Please let us know what your new account name is and we will follow-up with additional information. We will also send you instructions on how to reset that account's password.

I have alternate blinking too. This is NOT a raid drive.

Your My Book World should not be formatted or you will lose all ability to access it through the Network -- it will simply become a hard-drive at that point. There is software installed on the hard-drives that communicate with your Router in order to obtain an IP and be available as a Network Drive. If the drive and the Router are communicating, you should see an IP in the DHCP list of your Router. It is possible that the My Book World is not setup for DHCP, so if it is placed in an alternate environment with incompatible static IPs, it won't be able to access the Internet or be available locally. You can try a hardware reset on the drive and see if it pops up in your Router's DHCP/Client list, at which point it should also appear locally and over MioNet (MioNet will need to register the device to an account before it will appear in MioNet, but it must detect the drive locally in order to attach).

1. Turn off My Book World
2. Identify the reset button on the back of My Book World
3. Depress the reset button while restarting My Book World
4. Keep the reset button depressed for about 10 seconds after you see blue lights on My Book World

sounds like you are using the wrong power supply. Check the amp output on the power plug you plug into the wall make sure its the same as the amp input of your external harddrive
