I have a ST1000LM014 that has the signs of a corrupted NAND, I'm going to follow the steps outlined in other threads on how to reinitialise it.
But I need a TTL adapter that can communicate with it. I've got a CP210x that works fine with other Seagate models, but it wouldn't give any terminal response with this drive.
I've also tried with a PL-2303HXD, that would give a terminal response, but its just all random characters.

https://forum.hddguru.com/viewtopic.php?f=1&t=26917the OP seems to use PL-2303 but has done some serious hacks to get it working. But he confirms that the standard config of 38400 speed, 8 data bits, no parity, one stop bit, no flow control is what it should be set to.
The voltage on the Tx and Rx pins of the drive measure 1.8v. Both those TTLs are supposed to operate at that range, but something is going wrong.
Does anyone know of a specific TTL adapter that will work here?
Could it be that the PL-2303HXD does work ok normally but the corrupted NAND is preventing a correct read out?
