Idstorage data is stored at first raw partition (code 0x1). Use [1] to extract.
Structure
First 0x20 * 0x200 bytes of the partition is the index table, an array of 2-byte integers, which maps idstorage leaf to idstorage index. To find the index of a leaf, go through the array and note index of the element with the value of the desired leaf. Then, seek to 512 * index and read out the leaf data.
All leafs are of size 512 bytes.
