Saved image extremely small

I created an image from my Bootcamp partition which Winclone 8 Standard tells me completes successfully however it completes very quickly and the file is only 631 bytes for a 50GB partition.

I am on Mojave 10.14.6

Open the log and it should tell you what the issue is. It sounds like a disk related issue (try CHKDSK) or the helper tool is crashing.
