Disk
The following content will show you how to create a dual-partition flash disk
for booting up a Linux system from the first partition, while saving the root
filesystem in the second one;
1. Insert a TF card into a TF card reader and then connect the
reader to your PC; execute the following instruction in an Ubuntu
system to view the device name of the TF card;
$ dmesg | tail
Device Information:
...
[ 6854.215650] sd 7:0:0:0: [sdc] Mode Sense: 0b 00 00 08
[ 6854.215653] sd 7:0:0:0: [sdc] Assuming drive cache: write
through
[ 6854.215659] sdc: sdc1
[ 6854.218079] sd 7:0:0:0: [sdc] Attached SCSI removable disk
[ 6854.218135] sd 7:0:0:0: Attached scsi generic sg2 type 0
...
The above information shows the TF card device name is /dev/sdc;
2. Execute the following instruction to view the path where Ubuntu
has mounted the device automatically;
$ df -h
Device Path:
. Filesystem
...
/dev/sdc1
At the end of the line starting from /dev/sdc1 you can see the device path
is /media/disk;
