I thought rather about shortcutting the predriver of the motor. And that's why I first will try to apply the cardboard in the moment described at the russian page. Ther is at a 80% chance that it makes the same job as the jumper ;-).

I'm still sure that you can flash the firmware over serial via bootstrap. There you could flash what ever you want. But I don't think this applies for you disk becaus that would mean someone from Seagate service screwed it up... ;-)

*wow* I have a hard time with the russian page. Not sure if I need jumper of picture 3 or 4. Guess picture 4 because the print matches closer mine. Seems to me as we make a shortcut by purpose... Somhow I have no good feeling. I will postpone the operation to tomorrow. I'll keep you up to date. Hope I will not kill the drive... Regards Chilli

@MadOCer I think that the NS are the OEM parts. But that might be too easy ;-). @all I've a serious problem (sorry for little cross post but this seems the right place): My ES.2 ST3500320NS Firmware FSC6 (??) has obviously the BSY problem. (What is FSC6? Where there some fujitsu siemens equiped with it... ?) My problem: As soon as I disconnect the motor or the heads (or both) the HDD won't communicate anymore. As long as both are connected, I have communication. I can even send the spin down command by a quick sequence of Ctrl z, /2 and Z (using a terminal with Macros) but than I get the busy reply because I was to quick. I can not make it slower because than HDD goes into it's failure loop (sends busy informatino about all 8s). I'm really stuck. What's about the second service connector that is also connected to the same serial interface? Any possibilty to get the drive into bootloader and flash it via serial? Is the faulty log pointer at a different memory address for every firmware or would it be possible to reset it with a poke to a good state (if a poke could be done before drive get's busy)? I made a boot disk for ST3500320AS. If I ever can recover my drive from BSY error, can I use this or would I screw up my drive finally? (sorry for not going throuch all 119 pages but I allready get complaints from my family for sticking at the computer all day and night) Misc. *) The Serial inputs of the processeor are protected by serial resistors that prevent to blow it's clamping diodes when applying 5V level. *) I don't knwo why so many use USB to Serial + Serial to TTL, when you can both in one (TTL-232R-5.0V works fine) *) Rx and TX are correctly in this articel and wrong in some others (you have to cross Rx and Tx of HDD and Computer cable) Regards Chilli

With either of them or both disconnected I get no communication at all. Currently I'm stucked. So this thing has a serial communication. If the engineers at seagate are no idiots (and I don't know any id*** that is able to make such a peace of high tec), there is a possibility to get into bootlader mode and flash directly over serial. Exactly for such cases where the terminal is not available anymore. Anybody heared something about that? Another idea how I can get the thing in service mode or prevent it from spinning up? Help is appreciated. Regards Chilli
