Hello there. Been using 11.4 for the last few days and I think I might really like it. Thought getting my Broadcom wireless to work would be the hard part but I’m having real trouble with USB transfers for some reason.
Tried to copy a 700MB .avi to a USB stick yesterday, I know it’s good as I use it regularly. I get the KDE notification that it has copied the file (seemed far too quick but didn’t think much of it) and then went to watch it. Didn’t show up on my telly and when I stuck it back in the computer to check it had only copied an arbitrary 39MB of the file. Tried again this morning, copying three albums to my phone - I get the notification that copying files has been completed almost instantly, I let it sit for five minutes and of the three albums one track has been transferred.
It’s an Android phone so I can use a file browser to confirm they are there, but they’re all 0 bytes in size. Any ideas?
Broadcom
Install Broadcom Drivers from Packman
A 700MB file might take a few minutes to copy to a USB drive
In kde it can sit some time looking like it’s done or almost, just leave it.
Might be worth formatting the USB device all the same. If you have windows use that and try again. But be sure to always safely remove the device from windows first.

Did you safely remove it?
The kernel caches write operations in memory, and the program is free to
return, and use, that file. But it remains writing in the background.
However, if you try to safely remove (ie, umount) the device it will wait
for ever.
It would also be good to fsck the device.

Meant to say I managed to get that working this time, after finding that post the other day, so a belated thanks is due for that. Did struggle with in in previous attempts with openSUSE, not sure why seeing how easy it is.
I try to safely remove the device but it always comes back reporting that a file is in use, presumably being copied over in the background. I do get the taskbar notification of it being copied to the device almost instantly though, which means I have no idea how long the transfer is going to take.
So this wasn’t an issue at first?
Did you try a new user login. If you login with that, does it do the same?

or does that USB stick have some weird windows software on it? i’ve had
sticks i couldn’t use unless i re-formatted them.

It is classical linux behaviour, write ops are cached. What we did
traditionally was issue the umount command in console and wait for it to
finish. That’s the signal to remove.

A 700MB write to an USB 2.0 stick will take at least a couple of minutes, if you have an exceedingly fast-write stick. The common 4GB variety will take in excess of three minutes, IME.
You HAVE to safely remove a stick before physically removing it from the USB port, specially when writing large files. If you fail to do so you’ll certainly have errors in the file allocation table - assuming your stick is formatted for windows FAT, as most are, and you should run fsck (or scandisk in windows?) before writing to it again.
You DON’T have to safely remove if you only read (copied) files from the pen-drive.
After you click the safely remove (or eject) button, the stick light will blink until all writing is done. After it stop blinking (the removable device applet will show a pop-up saying this) you can remove the stick.
Also, if it’s connected to an old USB 1.1 port the writing will take MUCH longer.
