As in the title HDD ST32000542AS
I experimented on it so much (it was with relocated sectors, so a small loss)
And what's going on ?
Well, after the experiments (commands in the terminal), it ceased to be visible at all, both for the system and even in the terminal (via the RS232-TTL line)
First, after the experiments, all SMART and even the temperature information disappeared.
After another it ceased to be visible at all, now it is gone, as if it did not exist.
The plates are spinning, something scratchy and that's it.
The terminal is silent ....
The electronics did not fail because I replaced the electronics (with the EEPROM) from another functional one and the electronics on other platters started.
So something has disappeared from the "cymbals", apparently the situation is that the electronics do not communicate with the head.
But what how?
Is it possible to "activate" (reactivate) the disk in such a situation?
I know it's an old disk, etc., but maybe someone will have a similar situation someday and will want to recover data ...
