On a Debian 12 installation with Plasma desktop, I'm having a weird problem copying files to USB flash drives. Copying a 1GB file it should take a few minutes, but it completes instantly and reportedly successfully. The copied file appears to be the same size as the source file, but when I try to open it, it appears to be empty or corrupt.
Specifically, I'm attempting to copy an iso file to a flash drive set up with Ventoy. The Ventoy partition is formatted with exFAT, and has 5 GB free. When I attempt to boot into the offending copied iso file, I get an error (something like "magic number is incorrect").
I've tried both terminal and Dolphin to copy the file, with the exact same result in both cases: the copy operation completes instantly and the copied file appears to be the same size as the source, but the copied file doesn't work. Adding to the weirdness: the checksum of the copied file is correct.
Workaround, and proof that the problem is not with the flash drive: a virtual machine running Windows is able to properly copy to the flash drive properly. As expected, the process to copy a >1GB iso file takes a few minutes to complete, and I am able to boot into the iso file via Ventoy.
Am I somehow unwittingly creating a symbolic link or something silly like that?
Please help! Thanks in advance!
