 When trying to upload a new image in the media library I get an error
 "Failed to write file to disk" after the WordPress 4.0 update. This
 appears to be an issue in one particular wordpress as I tested this in
 other sites I manage and it works fine there.

 Are there any new known plugin conflicts with version 4.0?

Comment:

 Do you have enough disk space available? Can you upload a file via FTP?
 Does it still happen with all plugins disabled and a default theme (Twenty
 Fourteen or Twenty Thirteen) activated?

 The error code `UPLOAD_ERR_CANT_WRITE` is reported by PHP, see
 http://de1.php.net/manual/en/features.file-upload.errors.php and
 [source:/tags/4.0/src/wp-admin/includes/file.php#L259]
