Hi,
í have a problem with this HDD. It was previously installed in an external USB3.1 Case and was being unused, as it seems, for several years (Date Code from 2017). The drive had only 6 Hours(!) of running time after i got it from my nephew a few days ago. He told me that this drive already showed signs of failing when connected via USB (slow writing speeds, he assumed defect sectors).
So i took it out and attached it directly to SATA and the SMART-Status told me, apart from some weird entrys hich seem to be normal for particluar Seagate drives, that the drive is healthy. Copying files went "smooth" until i got to a point at around 150GB, where transfer to the HDD stalled. From then on i had more and more drive access problems - until recently, where even the SMART Status cannot be read out. It is recognized by the BIOS, doesnt´t sound at this point exactly what you would expect from a failing HDD (no endless seeking, stalling recoginition) and Linux gives straight at the Boot process a lot of IO errors, but, as i can tell, without Head action. Cables and so on are not the cause of this problem.
I am quite sure that my nephew didn´t drop this drive accidently, he is extreme careful at handling such things and if so, he would have told me for 100%.
Since i simply cannot accept to declare a 5TB drive, which has now a total of ten Hours Runtime (and that for suree), as "dead", I´d like to get at least access to this drive via RS232 and give it a try with the options being given. Rejecting this HDD would be, because of its age and since its an OEM-Drive, impossible.
An ordinary PL2303 USB=>TTL-Adapter is of course given, but i am not aware of the logic level of this particular HDD. Is it know if this Type of drive requires an 1.8V logic level and if yes, is there a simple solution (apart from using level shifters) to get the 5V TTL down to this voltage? I´ve read somewhere else on this site a solution via an Resistor and a few other few parts, but the schematics are no longer accessible. The PL2303 itself unfortunaly cannot be modified. DC-DC-Converters, Transistors (547/548) would be avaliable too.
Many thanks & best regards!
