External USB Drive (Optional)
You can use the external Type A USB port to attach a data-storage device. The external USB drive
identifier is disk1. When the ASA is powered on, a connected USB drive is mounted as disk1 and is
available for you to use. Additionally, the file-system commands that are available to disk0 are also
available to disk1, including copy, format, delete, mkdir, pwd, cd, and so on.
If you insert a USB drive with more than one partition, only the first partition is mounted.
FAT-32 File System
The ASA only supports FAT-32-formatted file systems for the internal eUSB and external USB drives.
If you insert an external USB drive that is not in FAT-32 format, the system mounting process fails, and
you receive an error message. You can enter the command format disk1: to format the partition to
FAT-32 and mount the partition to disk1 again; however, data might be lost.
