working of read & write request to mass storage

[LInsec]

hi ,
I am a newbie to linux . How does the read & write request from a command prompt go to usb & retrieve the file ? Can some one explain the whole mechanism ? When a read request is given , I/O manger sends the request to file system manager (FSM) and from FSM to mass storage device drivver and from there to mass storage , is this right in Linux ?

Hi,

Let me give it a try...

Mmmm....

First you have to mount your usb. After which you can already change permissions in your usb files using the chmod command in terminal/command prompt.
