Problems with baud rate in 7200.11

[AOnD]

Hello people!

Somethimes I have problems to repair the 7200.11 hdds with PC3K. I tried many solutions, and actually It's used to work change the pcb for a donnor with the native eprom.
But sometimes is not, and don't know why.

It's supposed ok, or just I had good luck with the change of pcb (with native eprom).

Anyone have the same problem?

Thanks!

I'm not sure if I understand your problem correctly. If you're referring to the baud rate at which to work with the 7200.11 in diagnostic mode, it is 38400. The PC3K is not always successful in repairing the two usual 7200.11 problems- translator and constant busy. In these cases it is best to use the manual method which has been documented in this forum extensively.

Yes, I have tried. But even with the windows terminal I couldn't unlock the terminal, I've tried also the shortcircuit to unlock, but it didn't get access...
Did anybody fix any HP12?

Thanks!

How far can you get with PC3K fixes?

What FW revision shows up in PC3000 (Not the label).

I fixed any 7200.11 except the HP12, and one that read the id, serial and the firmware wrong like ST_MQ56, ... and think its because of the eprom or head problem, but I showed that the heads are ok, so...allmost for sure it's the eprom. What do u think?

And now also I have another case of SD15, that have boud rate problem, and this is because of the pcb or because it's just locked. This is my real question!

Thanks!
