Friends. My friend encrypted a usb pen drive (ScanDisk) using windows and gave me.. he told the password to me. That drive has got some inbuilt software for encryption. All normal usb drives are automatically mounted in my debian box. My usb device is /dev/sda1. But, this pen drive can not be accecible. Can not mount this manually too. How to mount an encrypted usb pen drive? thanks. T.Shrinivasan.
