Any way to update Hitachi Travelstar firmware?

gang I've been web-searching for updated firmware or a way to do it on Hitachi travelstar internal 2.5" hdd... I have one that is producing frequent read errors, but running chkdsk the drive is 'squeaky clean' from a surface standpoint. I was hoping I might update..... can't find a thing

this drive failed the HP builtin [BIOS] HD tests, short and long, and failed the HGST diags tests, short and long [though the SMART status was all rosey :)] Specifically the tests point to read-access failures which produce a string of Windows 7 system 'critical' events since the OS timing is scrambled by fetches that return no response.

nagging in the back of my brain is an ugly scenario: what if the issue is with the Mboard component? what would clue me in that the drive interface is at issue ? disc is a lot more likely I agree but it just doesn't feel like an ordinary disk fail
