Hi All

all possible commands it showing that the pendrive is write protected
it cannot be fomatted

I have tried fdisk,cfdisk,gparted,dd, rm * etc
pendrive is transcend 8 gib but it showing 530gib of size

Pls help me regarding this issue.

Is it unmounted? Check the output of df -h command.
Unmount USB and execute format it.

[linuxsupport]

yes it is mounted, I have tried that method also

[devils casper]

USB disk should not be mounted. Its not possible to format mounted partition. Unmount it using umount command and format it after that.

install gParted and then unmount the pendrive and then format.
BTW,what's the command that you are using to format the pendrive.

or else
you cd to pendrive and issue the command
rm -rf *

[linuxsupport]

I have try all the possibilities. When ever I type the command
#rm -rf *

the file are deleted, After that I gave the #ls
that time I can able to see the content residing in the folder.

As I asked in my first post in this thread, plug-in USB and execute df -h command. Post output here.

tail -s 3 -f /var/log/messages
df -h
