Then there occurs a situation where one film is not copied and the system has to be shut down and rebooted again to continue. But the film, which blocked the system, can not be copied again. But it can be handled with windows 8.1. Is there a cache or other "memory system" in Fedora (i.e. F28), which can be deleted, so hat Fedora can copy this blocking film again? I have a similar problem in Windows 8.1, but his is solved, when I reboot Windows. > My system: Acer Laptop Aspire E15 E5-571G, cheap USB adapter to an external disk (old internal disk used as external disk with usb adapter). Windows 8.1 on the laptop internal disk, F28 on an USB 3.0 32GB Flash medium. It's impossible to answer this without knowing what you use to copy the file. Various GUI tools have their own caches. Command line tools generally don't. Also, you say it works after a reboot. Does it work after logging out and in again (no reboot)? IIRC in older versions of Fedora there was an issue of USB buffers clashing in some way with kernel huge pages (I forget the details), which would make copying large files to external devices very slow, but I haven't seen anything like that in several years. poc _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
