Elphel393 series cameras support recording in two modes: normal recording to a file system and fast recording to a raw disk or disk partition without any file system on it.

New page

As it was mentioned in [[Camogmgui | camogmgui]], ''camogm'' can save images to a raw partition or disk in fast recording mode and you need to do one additional step to extract these images from such a partition. This short note describes how to get images from raw partition.

1. Download [[https://github.com/Elphel/elphel-tools-x393 these scripts]] to your PC.

2. Connect camera to eSATA port, power it on and wait until it has loaded.

3. Copy ssh key to camera. This step can be skipped if it was done before.
$ ssh-copy-id root@192.168.0.9

4. Run ''int_ssd_download.py'' script to dump camera's raw partition to PC.
$ ./int_ssd_download.py -c root@192.168.0.9 -n 1 -bs 100 -bc 1 .
root@192.168.0.9: connection ok
root@192.168.0.9: raw partition name: Crucial_CT250MX200SSD6_1531103B6ABA-part2
umounting /dev/sda1
root@192.168.0.9: Enabled connection: internal SSD <-> PC
Connect camera (eSATA) to PC (eSATA/SATA). Press Enter to continue...
[sudo] password for mk:
Getting raw partition data from /dev/sdb2
1+0 records in
1+0 records out
104857600 bytes (105 MB, 100 MiB) copied, 0.501566 s, 209 MB/s
Waiting for disks to show up:
[]
root@192.168.0.9: Enabled connection: internal SSD <-> Camera
Done
Here, the ''-c'' parameter specifies which camera to use and script controls this camera to switch internal disk to eSATA and find raw partition. The ''-n'', ''-bs'' and ''-bc'' parameters specify the number of chunks to download, block size in MB and the number of blocks in each chunk respectively. The script will create a subdirectory, which name is made of disk manufacturer, model and partition number, and download disk dump into this subdirectory.
$ ls -l

5. Use ''extract_images.php'' sctipt to extract images from disk dump.
$ ./extract_images.php Crucial_CT250MX200SSD6_1531103B6ABA-part2
