Question about Computers & Internet

1 Answer

The 3TB/TO My Book Essential with USB 3.0 that I purchased at Costco did not have a CD included. I tried a number of times to get it started with my MacBook and when I click the prompt button to "initialize" nothing happens. I've opened all the images of this style of WD hard drives on your tech support site (first 10 pages) but have found nothing that matches this model. Would you please direct me to the appropriate download for the manual for this equipment.

Try this page for the My Book Essentials USB 3.0 downloads: . The CD is on the hard drive as a virtual CD for most of the Western Digital My Books. When the drive is plugged into the computer, it should be recognized and then you can access the drive in the Finder. Then you will find the contents of the CD. If you want to use the WD software, for example, double-click on the icon.

If your MacBook hasn't recognized the drive being attached, then you need to fix that problem. Are the USB ports working for other (known good) devices? If you can, try a different cable between the drive and the computer. Try powering on the drive and connecting it to the computer when the computer is off. Then turn on the computer. (There are some reports of the energy-savings features causing the drive to fail to be recognized by the controller when attached when the computer is on.)

I hope this helps.

It decides for itself when to work or not. Plug in, no power. When it works it can function for a while but just suddenly shut down and doesn't go on again like I want it too.

A lot of external drives have a "sleep" mode that triggers after a few minutes of idle time, which can appear to be "off". If you are not seeing power (is there an indicator light?) then check the cables connecting the AC power adapter. Maybe the connectors are dirty and not making a clean electric connection.

First, please disconnect all USB devices and then perform the following steps:

Click "Start" button, type "devmgmt.msc" (without quotation marks) in the "Search" bar and press "Enter". Click "Continue" if necessary.

In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".

Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".

Then, restart your computer and Windows 7 will reinstall all USB controllers automatically.

for xp

click start control panel administrative tools computer management device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X

you will need to update/reinstall drivers

right click to reinstall drivers

if you can see your usb but its not working

ports(com&lpt)right click update driver

sometimes the wires inside the cable will be damaged due to bending or stretching or placing heavy equipment upon the cable

just replace the cable of the hard disk, when you plugged the external disk drive you got that windows could recognize the USB device change the cable everything should work fine again,

if you can see your usb drive but its not working

ports (com&lpt) right click update driver if this fails to fix the problem

check the USB leads that attach to the motherboard usually red white green black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems to a computer and its parts

if this fails to fix the problem

you might have to install a new usb 3 card they are cheap and easy to install you can buy these on Ebay very cheap

I have the My book Essential 3tb WD drive and windows 7 laptop. It used to work perfectly except that there was a problem with spark coming out of the usb which was replaced by WD and I even got a...

There are several free data recovery softwares that can get data off of drives that Windows explorer won't touch. Check out: If you don't mind voiding the warranty, you CAN take it out of the enclosure and try connecting it to another computer, but I really think the encryption is going to prevent this.
The only other option would be to send the drive off to a data recovery specialist which is usually extremely effective, but can be very costly (starting around $400).

Does My Book 3T need to be specially formatted for an iMac?

The Mac can read FAT32 and NTFS (with NTFS-3G), so, no, it does not need to be specially formatted for iMacs.

Computer doesn't recognize hard drive

Basic Troubleshooting:

-Check all connections (Ethernet, Power, USB, etc)
-Install the appropriate driver for the device, usually included on a CD
-Double Check compatibility with your system (system requirements usually on packaging of product)
-If you haven't rebooted since you set it up, then reboot, this fixes a lot of things
-Try the product on another computer
-Try different cables/ports on the comptuer.

If nothing works, then send it in if it's under warranty or contact a professional service.
