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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1891768/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
