Recovering BWX-100 videos from the SD card with only the DES server available

Written by Randy Campollo on . Posted in MVI.

Issue: A customer needed to pull the footage off a BWX-100’s storage card but did not have the technical ability to create a Linux live USB. They however had the SD card, a card reader, and physical access to the DES server.

Resolution:

1. Ask the customer to connect the USB card reader with the SD card inserted to one of the server’s available USB ports.

2. While logged in to root in the DES linux server instance, run lsusb to confirm that the SD card is properly detected. This may appear as a disk manufactured by SanDisk Corp.

3. Run lsblk to determine the location of the card’s storage partition. In the example below, it is /dev/sdc6

4. Mount the storage location as an ext4 volume using the command mount -t ext4 /dev/sdxx [mount point] where sdxx is the storage partition identified via lsblk. In the example below, we are mounting /dev/sdc6 to /media

5. Navigate to the mount point and copy the files from the disk to another location using your preferred file transfer method (scp/ftp).

6. Once done, unmount the volume using the command umount /dev/sdxx where sdxx is the SD card partition that you were working with.
