My Western Digital external hard drive has just stopped showing up in Windows Explorer. I can see it under Disk Management. I also have irreplaceable data on the drive. I'm greeted by this message when first loading into Disk Management.
I think your images were too high resolution and so cannot be displayed. Try uploading again but at a small resolution so that the image sizes are only 100KB or so each. Right clicking on them causes a sub menu to appear but it does not give me the option to "open in a new tab" either. Incidentally you mention "Disk 4" but there are only three broken images not 4.
