The walkman is plugged into my workstation (running 42.2 with KDE desktop) using it’s usb cable and I am trying to copy my music data to an SD card in the device. I have formatted the SD card using the walkman setup as instructed and when the usb lead is plugged in the Device Notifier pops up with 2 actions offered:- Download Photos with DigiKam and Open with File Manager. If I open with file manager (dolphin) I can see all the directories created by the Walkman and can access the target Music directory. So far so good.
My first problem has been the inordinate length of time it took to copy the music files. I know the USB port on my system is not the fastest but it took overnight to copy the files I wanted. I have tried a card usb adaptor but this didn’t solve my next problem:-
My second problem was that unfortunately my files required more space than available on the SD card. (128gb class 10) The result was that most directories were copied over but not always their entire contents of track files. The data comprises classical music works so I then had to investigate each work to ensure it was complete. In order to make space I had to delete some directories (works) so that those that remained were complete. The problem is that even if I delete the directories and files I am willing to omit, no space is freed up according to dolphin. I have tried re-booting walkman device, removing card and putting it into adaptor but nothing worked. Does anybody have any idea what is going on and why the space freed up by deleting files and directories is not being released?
Finally I thought I would try and use console and go directly to the Music directory on the SD card rather than working through dolphin. Unfortunately although the device seems to be auto mounted I cannot find a way to navigate to it from the command line. Here is the result for fdisk -l:-
fdisk -l

Clearly the usb device is at /dev/sdb1 but how can I get there on the command line and why is there no mount directory in my system? Where is USB device mounted?
Grateful for some help please.
