The image does not mount or shows broken pipe
Low risk✓ ProvenWhat you see
- ShadowMountPlus rejects the image or the mount fails, sometimes with broken pipe.
What it means
ShadowMountPlus rejects your backup image, or the mount fails, sometimes with broken pipe. There is also a user report on the ShadowMountPlus issue tracker of exFAT images failing to mount with broken pipe on one build.
What to do
Check that the image is complete and the extension matches its format
.ffpkg is UFS, .exfat is exFAT and .ffpfs is PFS.
Compare your build with the report
The report describes exFAT images failing with broken pipe on a specific ShadowMountPlus build. Check which build you are running and compare.
When to stop
Changing the extension does not convert the image
Renaming only the extension does not turn the image into another format.
