(About removable media, not the case from the user since it was a bug solved with an update)

This behaviour happens because when the drive is mounted you are not considered the owner so a trash bin cannot be created. No uid or gid was assigned and since a trash bin folder cannot be created in the drive you are only offered the choice to delete the files automatically.

In that case you have 2 options: cut the files in to your Linux file system and delete them there (which defeats the purpose of press delete and the files are deleted) or make sure you are assigned the correct permissions when mounting the drive.

Create a new rule for your auto-mounted drives with these lines, use your favorite text editor for that

gksudo gedit /etc/udev/rules.d/10-my-media-automount.rules

# vim:enc=utf-8:nu:ai:si:et:ts=4:sw=4:ft=udevrules:

#

# /etc/udev/rules.d/10-my-media-automount.rules



# start at sdb to ignore the system hard drive

KERNEL!="sd[b-z]*", GOTO="my_media_automount_end"

ACTION=="add", PROGRAM!="/sbin/blkid %N", GOTO="my_media_automount_end"



# import some useful filesystem info as variables

IMPORT{program}="/sbin/blkid -o udev -p %N"



# get the label if present, otherwise assign one based on device/partition

ENV{ID_FS_LABEL}!="", ENV{dir_name}="%E{ID_FS_LABEL}"

ENV{ID_FS_LABEL}=="", ENV{dir_name}="usbhd-%k"



# create the dir in /media and symlink it to /mnt

ACTION=="add", RUN+="/bin/mkdir -p '/media/%E{dir_name}'"



# global mount options

ACTION=="add", ENV{mount_options}="relatime"

# filesystem-specific mount options (777/666 dir/file perms for ntfs/vfat) 

ACTION=="add", ENV{ID_FS_TYPE}=="vfat|ntfs", ENV{mount_options}="$env{mount_options},gid=46,dmask=000,fmask=111,utf8"



# automount ntfs filesystems using ntfs-3g driver

ACTION=="add", ENV{ID_FS_TYPE}=="ntfs", RUN+="/bin/mount -t ntfs-3g -o %E{mount_options} /dev/%k '/media/%E{dir_name}'"

# automount all other filesystems

ACTION=="add", ENV{ID_FS_TYPE}!="ntfs", RUN+="/bin/mount -t auto -o %E{mount_options} /dev/%k '/media/%E{dir_name}'"



# clean up after device removal

ACTION=="remove", ENV{dir_name}!="", RUN+="/bin/umount -l '/media/%E{dir_name}'", RUN+="/bin/rmdir '/media/%E{dir_name}'"



# exit

LABEL="my_media_automount_end"

Reboot your computer and your ntfs drives will be mounted using this custom rule, to change the permissions for the mounted drive have a look at the line $env{mount_options},gid=46,dmask=000,fmask=111,utf8", the option gid=46 should mount the ntfs drive with group privileges (46(plugdev) is the group that allows a user to mount a drive in Ubuntu), fmask and dmask settings to write, create, delete files/folders on the drive.

Change it according to needs. You will need to sort out other file systems by yourself according to to each type but this should get your started.
