I have been mounting an NTFS file system on a Windows laptop without any problems whatsoever with a Debian Live DVD:
$ uname -a Linux debian 5.10.0-18-amd64 #1 SMP Debian 5.10.140-1 (2022-09-02) x86_64 GNU/Linux and even though Linux utilities are telling me I do have space on the drive: $ date; sudo df -h | grep "Filesystem\|/dev/sd" Sun 14 May 2023 06:55:23 PM UTC Filesystem Size Used Avail Use% Mounted on /dev/sda1 286G 167G 120G 59% /media/user/60320G593EB7250F $ $ date; time sudo du --summarize --human-readable /media/user/60320G593EB7250F Sun 14 May 2023 07:13:43 PM UTC 166G /media/user/60320G593EB7250F real 0m45.230s user 0m1.073s sys 0m15.443s $ when I try to save or download a file I consistently get the same error message: $ cp "No space left on device" > No_space_left_on_device.txt bash: No_space_left_on_device.txt: No space left on device that started happening right after a WiFi connection at a library was shutdown, which I waited for with my script running, accessing the Internet, because I wanted to test such a case. Script "gracefully" worked as programmed to do, but that other error started right after the connection was cut off. I have no idea how could those two things be related! Why would that happen? Any suggestions, please? lbrtchx
