So, the problem turns out to be my lack of detailed knowledge about the storage limitations of ESRI Grid. One of the top level folders which contained the Grid had a space in the name. I completely forgot about this limitation singe the geodatabase, shapefiles, etc. do not have this limitation. It is funny, because I always tell my students - NEVER USE A SPACE IN THE NAME OF A FILE OR FOLDER!

I am trying to find the cause of a really strange problem. At this point, the problem is academic because I already have a solution/work-around. I have a 28GB DEM Mosaic in GRID format that will not open when it is stored on my local RAID 5 array. ArcGIS Pro 2.3 gives an error of "cannot load data - unsupported format." All associated GRID files are contained within a top-level folder (so no files are missing). I can literally copy the folder from the RAID to another local or external non-RAID drive and open it without a problem. Same DEM that didn't open from the RAID but now opens from anywhere else. The workstation has many cores and 128GB RAM, so it is not a performance problem. I can open 50GB IMG files from that same RAID drive. I receive the same error trying to open the DEM on another computer after mapping that RAID drive. The same DEM works fine stored on an external RAID 1 array. My solution was to store the DEM in a file geodatabase - which works fine on the RAID. Any thoughts as to why the same fairly large GRID format raster can be opened on all other drives but not on a RAID 5 array?

I wrote the original question but had a colleague submit before my ERSI login was sorted out. The symbology is bad, but what appears to be one long line is actually two - split right at the confluence. The drainage line layer seems accurate. Based on your reply - that every drainage line should correspond to one catchment - it seems like the Catchment layer is wrong. What might cause the stream segmentation - catchment grid - catchment polygon - drainage line processes to result in a single catchment with two drainage lines? The underlying data is a LiDAR-derived 10ft pixel DEM for a mountainous area. Thanks, Shawn
