Data recovery and disk repair questions and discussions related to old-fashioned SATA, SAS, SCSI, IDE, MFM hard drives - any type of storage device that has moving parts

Hello,
HDD data from label:
Toshiba MK1926FCV
HDD2517 D ZD01
S/N 66[...]3P GP0 EC.A
814MB (CYL1579, H16, S63)
On PCB: 416 B0/S0.16N 814MB
The disk was functional but with lots of bad sectors. I started to deal with serial interface (9600, 8N1, two pins next to M/S configuration). Due to lack of any documentation I checked every 1 and 2 character combinations possible. As could be expected with one of the commands (most probably PF or PI - I do not remember exactly) the terminal hanged. So I switched off and on the power supply. Currently the disk does not spin up upon power on. In MHDD/Victoria it is detected as:
MK192XFCV, LBA size: 512MB
SN and FW - shows normally
and in error register additionally: ABRT
If I want to perform SCAN the disk spins up and starts heavy knocking.
I also connected only the PCB - the detection is the same.
It seems that I erased model information, or more probably just the information about number of connected heads - thus the knocking.
My question is: Is there a possibility to recover the drive?
Every hint/documentation/file will be welcome.
I have no knowledge about serial terminal in Toshiba drives (this was the first attempt to learn).
I have found some files for MK1924FCV but with different FW version.
Additionally I have (unfortunetaly not at hand) second drive of the same model but with incompatible PCB - it is detected only as slave (independently on jumper setting) and shows different SN than on the label.
