I recently uploaded a number of images into LR CC. A number of them appeared with highly saturated bands obscuring all or part of the images. After an hour with support the problem continues. I am using OS X. The banding seems to be random, appearing in some images one time and in others later. When I opened the obscured images into PS, they were normal.
Could this new a hardware problem or a problem with Lightroom?
This is a hardware malfunction causing your photo file to be corrupted. The problem could be any of the following: camera card, card reader or USB cable, hard disk, computer memory. You need to identify the peice of hardware that is malfunctioning by importing the photos again using different hardware, and if possible import to an entirely different computer to see if you can isolate the problem.
