Some export operations were not performed. The file could not be written.

I receive this message when I export RAW file to  JPEG file to an external disk: Some export operations were not performed. The file could not be written.

I have made the same procedure for 4 years without problems. But today my problems start. It is only possible to export the file to C: Not to other internal or external disks. And I have all permissions to the folders.

Some possibilities:

1. Not enough space on the external disk
2. The permissions on the disk has accidentally changed. (You have to actually check the permissions, rather than assume that you have the proper permissions).
3. The folder you are trying to write to has somehow accidentally changed in the Lightroom Export dialog box
4. External disk is not properly connected to your computer (maybe you need to check the cable connection and then restart both the disk and the computer)

I change my permissions, but it didn't help. Then I restart my pc, but no help. Then I restart my pc once again and now I can save JPEG file on the external disk.

What do the permissions need to be? I am having this same exact issue
