            Bug ID: 273201
           Summary: io error with exFAT flash stick using exfat-fuse
           Product: Ports & Packages
           Version: Latest
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---

I'm on FreeBSD 12 stable, amd64, with fusefs-exfat port built and installed.

Using exFAT formatted USB flash stick I get io error kn FreeBSD desktop, while
no problem with that file on the same flash stick in Windows.

I've written a 9GiB file on a USB flash dtive with exFAT filesystem on Windows
7 notebook. It works, without errors, disc check also gives no errors.

Trying to copy (or play) the same file on my FreeBSD desktop with USB3 port
gives “Input/output error” leaving 7722762240 (=0x1,CC50,0000) bytes copied out
of 9454933972 bytes.

dmesg says nothing after flash stick insertion
“umass0: SCSI over Bulk-Only; quirks = 0x8100
da0: quirks=0x12<NO_6_BYTE, NO_RC16>”.

I also mentioned the problem on the FreeBSD forum.
