Airtel 3G Usb Modem 7. 2 Mbps – E1731 Data Card — usb modem

Address:

Hyderabad, Andhra Pradesh

Hi,
I am using Airtel 3G USB modem 7.2 Mbps – E1731 Datacard.(no: [protected])
problem is recently i have formatted my OS and when i try to plug in airtel data card
the device is detecting but i could not install the application it is showing an error "Windows Cannot Access the Disc The disc might be corrupted".
I approached Airtel office malakpet, hyderabad, they told that its a device problem and to consult service center.But service center(Abids) people told that the device is perfect, there is a back end problem.
Even i posted a mail to airtel help, for formality they called me and told they will call me back after 3days.
But still waiting for that....

Regards,
Sreekar
