Problem with copying files to externel USB connected disk

[Joerg Lechner]

Hi,
I copy frequently TV films from my internal disk to an usb connected external disk. This
is ok for let's say a bunch of 20GB. 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.

Kind regards

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.

 Hi,
I use simply move (verschieben nach, German version) in the files menu (Dateien), shown at
the left hand side of the window, or cut and paste in the files menu. Copying using the
files menu shows on the one hand the files in the internal disk and on the other hand in
the external disk. I use two windows of the files menu.

My impression is that the "blocked files" are not corrupted by the copying
process, but Fedora says the files are corrupted - MS Windows says the files are ok.
Thanks for help.
Kind regards

So a GUI file manager of some kind, but you still haven't said which
one. Examples would be Nautilus (under Gnome) or Dolphin (under KDE)
but there are plenty of others.

Hi,
It's Gnome, didn't know that in this case I use Nautilus.
What do You mean with: [Please don't top-post on the list], sorry for the silly
question?

Kind regards

Putting your response at the top, above the text you're replying to is 
top posting.  Most people reading this list prefer to see questions 
first, followed by answers and top posting reverses everything.

Thoughts:
- external disk formated with fat32 => movie file > 4 GB ?
- try rsync ?
- try to move away the movie file from the disk under windoof. copy it back and try again
under fedora => does the same file make problems ?

Why do you need a usb adapter ?
Is the disk without enclosure (USB3 Interface) ?

Had a Aspice E5-574 without any errors regarding file coping via USB.

 Hi,
formatted ntfs, copied file with Windows (You can say Windoof), but still impossible to
copy with linux, I use an old internal disk as external disk without enclosure, therefore
usb adapter, usb 2 interface. The laptop is ok, but with Fedora possibly the beginning of
this error is a "path break down" during moving the file, therefore my question,
if some data of this file are kept in a "cache" and prohibits to copy/move
again, also after a reboot. Because copying this file is still possible with Windows, I
assume the file itself is still ok.
Kind regards

My understanding is that any such cache would be in /tmp, which is 
located on a ramdisk which means that it can't survive a reboot.  It's 
possible that there's some sort of "dirty bit" that's not being properly

cleared from the file, but I don't know enough about NTFS (I abandoned 
Windows before I had to use it.) to say for sure.  Next time this 
happens, try booting into Windows, doing a proper reboot and see if that 
clears this up.  If so, we'll know where to look.

IIRC you are running Fedora from a usb stick ?

I can't say how much RAM is needed during coping big files and if it is needed, but it
sounds to me like you running out of something, which could be RAM e.g. swap space.

Do you got swap space or enough RAM, esp. you are running a full blown (???) Desktop from
USB/RAM ?

Tried sysrescueCD ?

another point could be your old (?) external disk => bad sector, etc.
did you checked it with smartctl, etc. ever ?
My experiences are windows isn't that smart realizing bad disks.

If you need a copy tool with verify under Windows, maybe this one:
https://fastcopy.jp/en/

I used to checksum important files and keep that checksums, too.
