عندك الوسيط الخارجي .. للقراءة فقط ..

لذلك مايقدر يكتب عليه

لما عملت مونت للبارتشن اللي فيها الفيديوهات عملت لها read only يعني فقط للقراءة .. اما الكتابة لأ

لتصحيح الأمر اعد الماونت مرة أخرى باستخدام

mount -t vfat -o rw,remount /dev/hdb1

مع تعديلات بسيطة من عندك

mount: only root can do that

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
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
