Details tab please - to see attributes. You can check them yourself and post

Did you run any server stuff with that disk (media server??)

Took screenshot of properties of one of failing exe's and noticed it has 0 size on disk, any ideas how this can be fixed?

One thing I noticed and haven't otherwise come across is all the periods/dots in the file name/path. Usually only the period preceeding the extension [as in thisfile.exe] is needed, could be the many periods are the problem. Also noted is the file size shown is incorrect, should be larger for the file type, suggests there is corruption of the file or it is not all there/incomplete.

Quoted from www.experts-exchange.com/questions/28937891/Error-0x80070780

exe files don't show attributes. This is the point where kind of server admin is needed. I have very limited knowledge here

he APL attribute indicates those files are actually reparse points - ie: symbolic links to the 'actual' file. At a guess your de-dupe experiment removed the duplicates and left the symbolic links in place.

it appears that they are inaccessible because the link is still there but there is no underlying physical file as a target for the link.

Edit: more and more I read about this, and alike problems, more I see mention of backup made (often under Windows server 2012) and deduplication service disabled. Almost like a common point.

Hi
If I bite the bullet and reformat drive D (The HDD), should this clean up my problems?

Many thanks for all of the suggestions from members

If you put the same image back on, probably not. But I'm not sure, since I don't have all the info... :) Is this drive from some kind of backup system?

Open one of the problematic file in hex editor and check if there is anything but zeroes in it...

Bowlsys said:

No the drive was/is purely a local drive to this machine. It was shared on the Lan but nothing else.
Are you saying if I put the backup image back the problem will return?

Mounting Macrium image and manually copying the files is really no different that this...
How was it shared?
In my opinion (I'm no expert on this field), you can restore your files by putting back the same sharing software, that was there before you clean installed this system.

Or if you have Macrium image of previous installation (system drive)?? Make image of new system, put old one back on, restore the files (or set sharing software in another way) and then change system again..

Edit: reread that post of yours... Was the share used by some kind of server? Then setting that server could help.

Bowlsys said:

OK will check on status of images of drive C.

The disk D was shared purely using windows shares. The only things approaching a server are/were 3 NAS devices and a MAC.

Which one was writing on it (that ISO files)? NAS devices were writing / reading from share? Were you syncing stuff between them?
(I really hope some pro server admin will join this... sorry)
