USB 플래시 드라이브는 Debian의 Gnome에서 읽기 전용입니다.

내 컴퓨터에는 데비안이 있습니다. USB 플래시 드라이브를 연결했는데 Gnome 환경에서 제대로 열렸습니다. 하지만 내용을 복사하려고 하면 다음과 같은 결과가 나타납니다.

복사하는 동안 오류가 발생했습니다. 대상은 읽기 전용입니다.

속성에 가서 뭔가를 변경할 수 있는지 확인하면 변경할 수 없는 것 같습니다. 변경한 사항이 저절로 재설정됩니다.

어떻게 해야 합니까?

편집하다

사용하면 mount다음과 같은 결과를 얻습니다.

/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=udi‌​sks)

그리고

# 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 labels
So far the informational part. Next the mounting.
The command is `mount [-t fstype] something somewhere'.
Details found in /etc/fstab may be omitted.
       mount -a [-t|-O] ...     : mount all stuff from /etc/fstab
       mount device             : mount device at the known place
       mount directory          : mount known device here
       mount -t type dev dir    : ordinary mount command
Note that one does not really mount a device, one mounts
a filesystem (of the given type) found on the device.
One can also mount an already visible directory tree elsewhere:
       mount --bind olddir newdir
or move a subtree:
       mount --move olddir newdir
One can change the type of mount containing the directory dir:
       mount --make-shared dir
       mount --make-slave dir
       mount --make-private dir
       mount --make-unbindable dir
One can change the type of all the mounts in a mount subtree
containing the directory dir:
       mount --make-rshared dir
       mount --make-rslave dir
       mount --make-rprivate dir
       mount --make-runbindable dir
A device can be given by name, say /dev/hda1 or /dev/cdrom,
or by label, using  -L label  or by uuid, using  -U uuid .
Other options: [-nfFrsvw] [-o options] [-p passwdfd].
For many more details, say  man 8 mount .

# remount
bash: remount: command not found
# mount -t remount,rw/dev/sdb1/
# mount -t remount,rw/dev/sdb1/
# 

왜?
