I see that other people have been having the same issue as reguarding this URL http://community.wdc.com/t5/My-Passport-for-PC/Passport-Elite-500G-USB-Device-Not-Recognized-malfunctioned/td-p/74516
I am also having the same problem reguarding the Passport Elite where it is not fully recognized. I need to download the device drivers for the hard drive, need to know where I can get them to install them manually. I have tried through automatic update through windows but it recognizes that there are no drivers and then gives me an error message and closes itself out. I have tried to use the drive on a pc, and on my laptop, wont be recognized. Short of following through on the RMA that is created and loosing my information, I would like to have an alternative method. I would wish to retrieve my information before sending the Unit in. I have tried a data recovery company, but alas they need the device driver also. Where can I find the device driver for the unit?
