hfs+ file systems fail reading / writing large files
In the last quarter of 2020, I submitted this (https:/
In May 2020, when I updated from Ubuntu Mate 18.10 to Ubuntu 20.04, I noticed that reading/writing hfs+ formatted USB drives failed for large files. Files about 500MB always fail. I've also noticed failures for files down to about 100MB.
I suspected my several year old USB flash drives. The new USB flash drives failed the same. The flash drives work just fine when formatted with ext4. For the rest of 2020, I had to boot Ubuntu Mate 18.10 to write hfs+ drives.
Due to this bug and other bugs introduced via updates in 2020, and Ubuntu's failure to repair them, in January 2021, I installed MX Linux. For that saga see: Looking for a Linux with no serious bugs https:/
Simple test case:
1) Mount an hfs+ formatted drive (or format a drive to hfs+)
2) Write a file about 500MB to the hfs+ partition
3) Unmount the hfs+ partition (otherwise you just read the cache)
4) Mount the hfs+ partition
5) Diff the original file and the copy on the hfs+ partition.
I've tested these kernels:
hfs+ works on these kernels:
vmlinuz-
vmlinuz-

Ubuntu 20.04 fails on two different computers:
Lenovo FLEX 3-1480 and Acer E15 laptop.
Ubuntu Mate 18.10 works on both machines.

Thank you to Robert Crook who confirmed that he has this same problem.
This question expired after 15 days with no assistance.
Perhaps this is not the correct forum for this type of problem.
Does anyone have a suggestion as to where I might find assistance with this problem?
Thanks
