Thank you for reminding me about memtest86, I had a bad memory module. I am trying to RMA it now. It seems unlikely that the memory would go bad after about a year. Live and learn.... Ubuntu just updated to 22.04 with the kernel 5.15.0-27-genericOn 4/28/2022 1:56 PM, Chuck Anderson wrote:
What are the kernel version(s)? What filesystem?
I suggest:
- Try memtest86+
- Try a live Fedora 35 on a USB stick since all your other tests were relying on Ubuntu, even the Windows 10 which was a VM on Ubuntu. Fedora usually has much newer kernels, so if there is a Linux bug, it might be fixed already.

I have been chasing my tail trying to download a very large to my desktop. The bug is strange enough that it might be specific to hardware.
The issue is that I can not copy very large files accurately. The threshold value size of the file seems to be about 8589934592. Any file this size or larger seems to be uncopyable on my desktop.
I had downloaded a corrupted file of 71.9GB with Ubuntu 20.04, Ubuntu 22.04, Windows 10 virtua machine running under Ubuntu 20.04, Manjaro. All of theses OS;s were running on the same hardware.
I had no issues downloading the file from a raspberry pi with and external hard drive.
I have included the C file I used to create the files which also has some notes opn the results of the tests.
Any advice or help would be appreciated.
