Mybook premium edition 500gb malfunction, HELP

Error message
I did a quick test with the software provided with MyBook and a error message appeared witch said : cable test: read diagnostics sector error. My blue light is always on and circling. My computer does not detect MyBook. We can see that there is a F:drive but it does not give any detail of it, or access to it. I tried MyBook on 2 other computers and the same thing happened and one of them even suggests that I reformat MyBook. I use Vista and one of the other computer uses XP. I unplunged everything, rebooted everything, as clean as possible......same problem. Tried changing the usb cable, didn't work either. The first time I used MyBook on my laptop, every went very well, downloads and all. 24 hours later, total black way to access MyBook or have my laptop recongnize it. How can I resolve this problem? or should I return MyBook. How can I retreive my personal info on MyBook? Please help....

    Same problem, same attempts, i.e. XP and Vista, Laptop and desktop, new cable and diagnostics tool with "cable test: read diagnostics sector error"; nothing works. However I don't even see a drive letter. The "new hardware found" icon pops up in the tray then the "saftely remove hardware" shows up. I can see the drive if click on Safely remove hardware but still cant access it... Need help please!

I bought a 500GB Mybook. Package did not have a part, which was quickly and kindly sent to me. Support said the software was already on the drive, when I asked about an install CD. It never occurred to me...

You have to set up the drive on your new laptop. Then install the software and when it asks about a new backup decline. Go to actions/reactivate plan and that should do it. Let me know how it works.

Mybook 500gb shows 2199gb and cannot be read

This drive has been misformatted. You will need to plug the drive into your windows computer. Hold down the windows key and tap the e key. In the window that appears, find the MyBook drive. Right click and choose format. Select the quick format box. Make sure file type is set to NTFS. Click "Format". This operation will however remove all data on the device.

I can not link up with My Book World Edition 500GB

That is because the MyBook is set with a default IP address of You will have to put a static IP address in that subnet range in order to be able to see the external drive. Hope this helps....

My Book, Need upgrade to make it compatible with Mac Leopard OS X. Article #1716.

1) Go to 2) Click Downloads 3) Select MyBook, then your MyBook model (I selected MyBook Home, as it was appropriate to my hardware) 4) Download and install the WD Drive Manager (Mac)
Note that this software only updates the utilities that control the power button, drive lights, and capacity gauge. If the drive is otherwise not functioning properly, you'll probably need to seek alternate support: the hardware itself functions just fine for me as an external drive without installing any additional software or drivers.

MyBook 500gb won't show up?

I have had this problem with several MyBook hard drives. They work fine for a bit and then the windows xp OS fails to recognize them. If they do show up the computer warns me they are not formatted. My solution does not help fix the MyBook as is. However, if you have data you must have on it this may be of help. I simply opened up the MyBook plastic case. It is different for each drive. The Pro/premiums I have found you must remove the rubber packing to get at the latch area. After I removed the bare drive from the holder I used an IDE/SATA adapter kit with external power and plugged directly into a USB port. The drive was recognized immediately and I offloaded the data. The drive actually works better now then when it was in the Mybook holder. I am taking no chances though and have switched to LaCie drives. Hope this helps somewhat.
