My WD Scorpio Blue 2.5" drive started losing partitions when the drive (connected to a USB external case) would be plugged into any computer. I tried it with a different external case with same issues.
I created an account on the Western Digital portal site. Registered my drive and the filled out the RMA form. I decided to provide a credit card number so they would send the replacement first. I filled out the RMA at 11:30am and found out they shipped the replacement that afternoon at 4:30pm.
I found their web portal to be very end-user friendly and very informative. Folks, you cannot ask for better customer support than this. This is why I continue to purchase WD drives. This is the first drive that I have ever had an issue with, so I was not sure what to expect. I was very pleased with my experience. Thanks WD.
