~~tag>OOWOW dump howto~~

====== OOWOW create dump partition ======

After writing oowow image to SD/USB disk, for example by next command ''gzip -dc BOARD-oowow-latest-sd.img.gz > /dev/sdX'', the disk will have only 1st partition. After 1st bootup from this disk, 2nd partition will be created automatically by oowow. But in some cases if we need created it before 1st usage, we can [[#create-2nd-dumps-partition-manually]]

===== Create 2nd dumps partition manually =====

For some cases we need create 2nd partition before start oowow, for example automation restore images etc ...

```sh create-2nd-part-example.sh
# copy original parts
sdfisk --dump /dev/sdX | tee /tmp/oowow.parts 

# add dump partition
echo start=131072, type=7 | sfdisk --force -a /dev/sdX

# format 2s part as exfat 
mkfs.exfat -n dumps /dev/sdX2

```
