    Sorry - dunno hoe I reported as abuse! Simply mean to give more details - this is the second drive after having changed the first with the same error - and I got it to work first time with my laptop. The issue I have is with my desktop.

You have a bad drive, return and get a new one. Dont try plugging it in to your computer anymore as you may damage your computer.

    Well right off the bat it sounds like there is something wrong with your USB ports. What is the make and model of your computer, and how long have you had it? Have you ever overclocked anything on your computer? Ever had an issue with other USB products?

    Ok, here we go.... First we are going to check your main Hard drive for any issues.

    Step 1: Go to "My Computer"

    Step 2: Right click on main HDD

    Step 3: Click on "Properties"

    Step 4: Click on "Tools" Tab

    Step 5: Click on "Check Now"

    You may be asked to reboot the computer to check disc. When you restart it will say checking drive click any key to cancel, dont click anything, allow it to run the check. If no errors come up please get back to me and we will then go from there. Our next step will be to test the Ram in your computer.

    Yes we are going to have to chek your Ram. You are going to have to remove the cover of the computer to access the Ram. If you have more than 1 stick of Ram we are in business. Here is a pic of a ram module so you know what you are looking for

    We are going to remove 1 stick and boot the system as normal to see if the external drive works. If it fails take the other stick out and place the first one you took out back in and reboot the system. You will only be testing one stick at a time, so if you have more than 2 sticks remove all but one, and repeat the steps for all sticks. We are trying to single out the bad stick, if there is one.

    If a bad stick is found keep it out of the system and replace all other sticks back into the computer.

    Here is a link to a video on how to remove ram.

WD Software will not load up, and Windows keeps giving me an I/O error. With the I/O error, I am not able to see or access any files that I have on my WD MyPassport 1TB, SN WXD0AA9W6561

Have you tried another USB port.Try not using a USB hub and plug it into a different port on your PC. Also try temporarily disabling your virus and anti-spyware program. My virus program Antivir always blocks my WD software. There may have been an update that now blocks it. Check all your cables and plugs on the WD drive and if still not working try starting your pc in safe mode and see if the WD drive is recognized. Hope this was some help, Thanks for using FixYa

Just plugged in new wd 1tb hardrive to windows xp computer blue light flashing on book front but no icon on computer

Brand new?

Did you follow the instructions in the booklet that were packaged with the external disk-drive?

Did you try connecting the unit to a different computer?

Did you take it back to where you bought it, and ask them to demonstrate attaching it to one of their computers, as a demonstration that it works, or to prove that it is "defective" and the seller must replace it?
