The TeraStation comes with 4MB of flash.

The flash is used to boot the TeraStation.

It is split into 4 parts:

admin@HD-HTGLxxx:~$ cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00300000 00010000 "mtd0"
mtd1: 00070000 00010000 "mtd1"
mtd2: 00010000 00010000 "mtd2"
mtd3: 00080000 00010000 "mtd3"
mtd4: 00400000 00010000 "mtd4"


mtd0

Contains the flash header, kernel and the initrd.

mtd1

The bootloader

mtd2

Contains the bootparameters.

mtd3

Used to store the backup of the config files while updating the terastation.

mtd4

The full flash in one file. It is used when updating the flash.

You can dd the flash firmware image (allimage.bin) there to update the flash but it is better to use the official firmware update utility.
