And, there is one more great thing I gained from this two-week study.
56 ~ 57% connected to disk damage error
3 FAT boot partitions on USB
/dev/synoboot1, /dev/synoboot2, /dev/synoboot3
If it cannot be mounted
boot-wait (tcrp) and automount (rr) complement this.
There are addons such as:
If these three boot partitions are not mounted properly, they cannot be created.
There is a function that forces this.
This is a method I researched and came up with.
Force create the above three nodes with the /bin/mknod command.
Because this forcefully created node is not a stable node,
The 56-57% disk damage error still did not go away.
However, as a result of this function, there is no need to forcibly fake these nodes.
It seems to be more stable to connect to a USB device directly using "ln -s" in the form of a direct symbolic link.
I will discuss this improvement plan with wjz304 and spread it to rr to improve it into a more stable addon.
