Title:
hfs+ filesystems fail reading / writing large files
Status in linux package in Ubuntu:
Incomplete
Bug description:
I noticed a problem reading hfs+ partitions on a USB flash drive after
I installed Ubuntu 20.04 on two laptop machines. 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.
