Hi SRUTSSSSSSSS80, Having a difficult time translating your fist link (google refuses), but on first glance i can't spot anything of relevence I've already tried WD ROM recovery tool and had no luck unfortunately, unless it's a more recent version than the version posted over @hddoracle in which cas...

That would be a good solution, unfortunately i don't know anybody with such tools - if i did - i'd capture communications so us mere mortals could perform such operations manually or implement such a features in other software

This: Drive do not acknowledged receipt of the command mean, VSC not work in this mode yup, figured. Ok i think the next port of call might be programming the external rom chip in circuit while the drive is on and powered up - if it's indeed as i suspect a parallel flash, then maybe the MCU will cl...

I can not detects what happens by tx/rx blinking :) When you enter to work with modules, is some error? No, at one of my first posts in this topic I list all WD rom commands, read/write/erase When hitting the modules button i get 15/03/2017 13:40:31: The error in determining the number of heads 15/...

that certainly does appear to be the case :( playing around - tried checking for modules and tx/rx light up rapidly - is that any indication that the drive is indeed at the very least responding? do you think "restart and block loading FW by changing Rom image" would work? slightly off top...

This "DLL" files - programs for ARM MCU of drive, loader UCommand wait for SSSS Then send one "dll", this loader erases rom Then send second "dll" with rom image, second loader write rom image into MCU Interesting stuff, doesn't ARM have some proprietary software begin...

Yes, set work mode to Serial TTL and select port Ahh, i didn't realise your program had this functionality, i'll give a try No, it wait while drive start to send "S" symbols, XModem protocol yes, i figured it received "S" character - which presumably indicates a safe mode/servic...

In normal drive mode, drive supports VSC command via TTL In your case, I do not know You can download demo and test this ;) Analog of UCommand I mean, "WD Rom Recovery tool", if I remember rightly If WD VSC Commands are compatiable via a UART TTL adapter does that mean it's possible to se...

Yes, ROM image damaged :( No luck with UCommad or analog with TTL rom recovery function? With UCommand no luck unfortunately, i can access via terminal and read/write addresses, but i daren't write anything and don't have a clue where to start on that front :) are the VSC commands compatiable via t...

Of course, rom dump and empty copy of rom differs :) How exactly drive respond on reset? Well i have to put it in one of my afformentioned modes (by default it's just BSY) with rersistors set in "my semi detect mode" AMNF, TMNF display in red. evry 10 seconds or so RDY, DWF, DSC, DRQ, COR...
