Could you let me know the version of Lightroom that you are working on , also the operating system ?
Also please Go to the Preferences > Performance Tab, and uncheck "Use Graphics Processor
I not sure which version it is as I can't find where to see the version. Its definitely the latest version though because it was updated via Creative Cloud earlier today and it says that its up to date.
Graphics Processor tab is already unchecked,
.... to clarify, Lightroom CC 2015
The images that are showing as complete black, are they recently imported in Lightroom.
Also did you make any adjustments to these images,
To check the version of Lightroom : click on Help > About Lightroom.
Looking at the histogram there does not seem to be anything but black pixels in the file!
looking at the filmstrip some editing has been performed on this image, try going to the develop module and click reset to see what happens.
PS, as the other images in the filmstrip look OK, changing graphics processing preference is unlikely to make any difference.
I'm now getting a range of errors as follows:
Blacked Out Files
"The File could not be read"
"Unexpected File End"
"The File appears to be unsupported or damaged"
All of these problems seem to coincide with a recent Backup Drive I bought, which is a Netgear ReadyNAS set up as Raid1 for mirroring. Netgear say the files are fine but of they cannot support any software such as Lightroom and how Lightroom interacts with the Hard Drive.
I cant help but think the new drive is a very big coincidence.
It seems to be a corrupted file, could you please try to re import these files and then check the files.
Are you saying the 'blacked out' images were previously OK?
The other messages you are receiving would point to a drive problem, but don't rule out a networking problem (cables/connections etc.).
What does 'Netgear say the files are fine' actually mean? Have they checked the drive?
I've just unplugged the NAS from the router and plugged it straight into the laptop (Mac) - everything is fine now. It seems that the NAS drive isn't that compatible with Lightroom when plugged into a network.

Lightroom doesn't support catalogues on network drives, other than that I don't know of any reason why you should not be able to use this drive with Lightroom.
I would still check your networking hardware.
