I got this problem about a week ago.
Sharpcap fails to capture, or save a snapshot, and says "An error has occured while writing to capture file. No more frames will be written during this capture. Maybe the file is too big or the disk is full?"
The disk is not full.
- I tried with different partitions, same result.
Internal capture for plate solving works. On the same drive it doesn't want to capture.
Other capture programs like Firecapture and APT works on the same partition with the same hardware.
Camera is not open in another program at the same time.
I have this issue regardless the camera (ASI120MM and ASI178MM)
I tried different cables, different ports, no success. Btw, it worked earlier with the same hardware.
I tried to run SC as Administrator, no change.
I tried repair SC installation, no success.
I tried to lower USB traffic, no change.
It's usually dropping frames also, but not always.
Operating system: Win10, 64-bit.
SC: latest version.
The screenshots were taken through RD-connection, but this is the same from local as well.
I can't recall, but maybe it started after I installed APT for D-SLR work.
