[The Solution for Seagate 7200.11 HDDs]

As said your problem (whatever it is) seems like being NOT a BSY or a LBA0 (but you haven't provided yet ANY meaningful detail/info to confirm or deny this hypothesis)

I have two similar hdd one that works and the other does not. When I connect the hdd that works with the screw pcb hyperterminal communication with hyperterminal is perfect, when I separate the pcb, this is not connected to the terminal. In the case of the failed disk I can not get connected to hyperterminal in any way. Always using the same ttl converter. Because I can not ge achieve connection with the hyperterminal. Apologize because my English is very bad.

I want to know why the pcb is not connected to the terminal without being bolted to the hdd. From already thank you very much and sorry for my ignorance

My seagate 7200.11 responds to ctrl / z only when connected to the pcb disk. When I disconnected pcb I fail to connect with hyperterminal. Why is this happening?

Possibly it is not in one of the malfunctioning cases we are talking about (LBA0 or BSY).

A "normally working" 7200.11 terminal is accessible with the PCB connected to the disk (obviously), cannot say if a "normally working" one is also accessible when the PCB (powered) is detached from the actual disk (and/or one of the two sets of contacts are insulated), but I think it should as well. ;unsure:

I'll have a problem with the electric mass?. Will I be able to use a disk pcb other similar characteristics to recover my disk is damaged if its pcb I burned?
