Clean all, from the help of diskpart, should write zeros to all of the drive. Absolutely bad move for him.

What if the zero track is bad? Then a dead hard drive?

Ask permition to the owner of the drive to continue on and if you insist you will need at least a TTL adaptor and plug it to the drive like this :

@ abolibibelot - As it's been said earlier, you should try to connect it through SATA with a “reasonably current” desktop machine (less than 5 years to be on the safe side)
then if all is fine, open the whole drive with an hexadecimal editor (WinHex if you can, or HxD which is free) and post a screenshot of what you see.
but still get a 0 byte capacity and no drive letter, first check the SMART parameters (CrystalDiskInfo, HDTune...),

Do you think that recovering a lost F3 Arch drive ROM (like the one from the OP drive) would be a "problem" so big that so far only a bunch of data recovery guys know how to do it (and charge a fortune for it) if one could just "hot swap" a Seagate F3 Arch PCB ?
This does work for some drives like WD (with limitations like translator problems that have to be "solved" by for example "SMART HOT SWAP") but FORGET about using that method on something like a Seagate F3 Arch drive, at least without moving adaptives from original patient ROM to donnor....
I have already posted a screen shot. You can see it on page 1.

Would it be consistent with what is observed here ? Is it possible to fix through software-only means, by manually correcting the partition table, or MBR, or something ? I myself bought a used 3TB ST3000DM001 (bad, I know – I only got movies on it) in a Seagate Expansion enclosure, I don't quite remember the specifics, but when I opened it and connected the drive directly in SATA, the partition was no longer recognized, I had to re-format it in SATA to be able to use it (it was empty at that point). Could it be something similar ?

3. So you connect it with old (2TB limited) SATA, and it identifies as wrong size (you will get drive's correct size modulo 2TB binary; which means 3TB drive which has 3 000 000 000 000 bytes will be shown as remainder of (3 000 000 000 000) divided by (2 * 1024 * 1024 * 1024 * 1024) which is 800 976 744 448).
4. So you then connect it to the modern (NOT 2TB limited) SATA, and it will not read, because all partition tables and filesystem bootsectors, and sometimes filesystems internally are put there based on 4K sector, but the drive is now properly identifying as 512byte sector. You look at partition tables and everything is 8 times smaller than you expect it to be.

That adapter you posted up ther ( the Max232 one ) probably would not work. Just from memory, the levels in the max232 would be about +-5V, and in your hdd you need something able to understand lesse then 3.3V probably. Even a MAX3232 one could have problems.
Also, your adapter gets power from where ? Some get it from the serial port through some creative means, but others need the connected board to provide it ( like modems, routers, etc that have a +3.3V pin in its uart ) .
You will need some adapter like those mentioned by Spildit, or at least some of those people build with old cell phone cables. One based in the CP2104 chip would be easier, as it should support all voltages from 1.8V and up.
