Hi, I would like to create a Flow Direction using a Mosaic Dataset output. When trying to run the Fill process, I got the error messgae "ERROR 010429:Error in GRID IO: S_VXfer: Read error.". This error appeared when the percentage of completion is already in 99% which is very frustrating cause normally, when there is an error in Fill/Flow process, error occured right away or a few minutes but would not take about 40hrs running it and reaching 99%. Any input or suggestions on how to resolve this issue would be highly appreciated. Thanks!
