Pen drive problem...
 

Hi,

I am using Transcend 4GB (JF V10). There is no problem in mounting the device but when i tried to copy or add a file in to the device (using file browser) it is giving error message as "cannot copy/delete device is write protected), but i can copy or delete or write a file into the device using command mode. What must be the reason...?

and... once it is opened using file browser ... it is not allowing to do any operation even thru command mode.

It is working properly in Windows XP.

Most likely it's just a permissions problem. To give full rights to all users (read, write, execute) you can mount it as follows
Of course you'll need to substitute the correct device and mountpoints for your system. See the man pages on the mount command for more info
