This is a new issue for me. Whenever I try to copy any type of file to a connected drive (flash drive, internal secondary hard drive, whatever) it will not complete.
Graphically I use nautilus for my file manager, drag and drop or ctrl+c ctrl+v produces a progress bar that winds up hanging up at the last few kilobytes and will not complete. I've let it sit for hours, when all it should need for the whole process is a few seconds (or minutes for larger files). Trying to cancel it doesn't do anything, force quit produces nothing, even 'pkill'ing the process doesn't cancel it. I can't even unmount because the process ties up the device rendering it "Busy" according to my system.
Via terminal, I don't get a progress bar or completion time but using cp /path/to/source /path/to/target just hangs, and will not complete. Same things happen, ctrl+c doesn't stop it, can't term the process. In either scenario I wind up having to force my computer to shutdown in order to retrieve me device.
I thought maybe it might be due to the drive(s) being mounted as read only (I don't know how/where to check how my devices have been mounted, but I just took a guess) so I manually mounted my flash drive and manually tried to copy something:
ra@ra-desktop:~$ sudo mkdir /mnt/8G_flash
ra@ra-desktop:~$ sudo mount -t vfat -o rw,users /dev/sde1 /mnt/8G_flash
ra@ra-desktop:~$ cp /home/ra/Documents/confirm /mnt/8G_flash/
cp: cannot create regular file `/mnt/8G_flash/confirm': Permission denied
Hopefully someone can help me out here. Thanks in advance.
