I am new to ubuntu. My External HDD USB 3.0 used to work on Ubuntu when the file system was not encrypted. But after I started using sda3_crypt, the USB drive is not getting mounted automatically. I tried using mount command but it is not recognizing the file system. The hard drive is in FAT32. Even after I specify mount -t vfat (etc.) it is not working. Can anyone help please..

Thanks in advance.
