I have Debian on my PC. I insert a USB flash and it open just fine in my Gnome environment. But when I try to copy something in it I get:Error during copy.The destination is only for reading.When I go to properties to see if I can change something from there it seems I cannot  the change I am making resets on it's own. What should I do?EDITIf I use mount I get: /dev/sdb1 on /media/KINGSTON type vfat (ro,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0077,codepage=cp437,iocharset=utf8,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks)and# mount -o remount,rw/dev/sdb1/Usage: mount -V                 : print version       mount -h                 : print this help       mount                    : list mounted filesystems       mount -l                 : idem, including volume labelsSo far the informational part.
