Prior to an intervention, the raw tag was used for two different things:
- Questions involving the camera RAW format. All of these questions that weren't closed were retagged with the camera-raw tag.
- Questions involving "raw" (uninitialized) hard disks, thumb drives, etc.
Since the first use has been eliminated*, the raw tag is now restricted to the second use, thus making it a clear meta-tag.
Please burninate the raw meta-tag now that it's been disambiguated.
* - There are still two questions that relate to camera RAW, but they've been closed as off-topic/not constructive because they solicit software recommendations.
