drivers on ur pc r outdated .... update them from net they r present free of cost . search on google abt how to update drivers..

Try formatting the laptop and insert it. it worked for me.

I bought a new Sony NWZ-B133F/BCE Walkman. When I plugged it to the USB the drivers got properly installed, but the player does not show as a removable device or any other device in My Computer.
just follow...be sure your player is connected to pc
go to my computer right click>>properties> IN HARDWARE TAB select device manager>portable audio>right click select update drivers>click next>tick the option let me choose driver for this device>next choose usb mass storage driver from two options click next....
AND U R DONE....

See if your players hold button is on and when you connect it to your pc, hardware update wizard comes up, in tat choose the second option(ie install from...(advanced) and click next and choose 'dont search i will choose the driver to install' and press next.... check show compatible hardware choose usb mass storage and there you go.....
