It seems that when i want to paste a file to my usb, it says "the disk is write protected". . . but when I used the USB to another computer, i can paste files. . . I don't know why such thing happens, is it because I have to adjust a setting or something in my system that will allow me to copy files from my laptop to my usb?
some USB flash drives have a switch on them for write protection ...check that out, If this is not the case then try to format your flash drive and asign it a different drive letter. If you cannot format under windows do it under command promt when windows starts up (use F8 @ boot time and sellect "Start windows with command promt" i think thats the option )
