I have a Mini Mac that I share files via an USB flash drive formatted with hfs+ from the laptops with Ubuntu installed. I had no issues with Ubuntu Mate 18.10. I noticed that very large files, typicality larger than 100 MB, would have read errors or sometimes have a zero file size. One particular file about 500MB fails nearly every time. Other files, down to about 100MB fail sometimes. I bought a new USB flash drive, but have the same failures on that. I have an identical flash drive formatted with ext4 which has no issues. I'm currently booting to Ubuntu Mate 18.10 to write the hfs+ USB flash drive. 1007 ceres ~ cat /proc/version_signature Ubuntu 5.4.0-42.46-generic 5.4.44 1000 ceres ~ lsb_release -rd Description: Ubuntu 20.04.1 LTS Release: 20.04 1005 admin@ceres ~ sudo lspci -vnvn > lspci-vnvn.log pcilib: sysfs_read_vpd: read failed: Input/output error pcilib: sysfs_read_vpd: read failed: Input/output error --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.6 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: uschcld 1581 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: MATE DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2020-05-17 (91 days ago) InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Release amd64 (20200423) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 0408:a030 Quanta Computer, Inc.
