It keeps always busy. It spins OK, no bad noises.
I tried to swap PCB, but same thing, until I put the original one and I started to work.
I did a FW backup, all ok. Accessed data )I saw the folder structure, but it was giving some errors and needed to do a power off/on.After that it went to the same log.
I then tried a hotswap (followed the rules to do it), but after standby and calibration it clicks.
I found that the patient have 1 head (on DE it showed only 1 head) and on the donor (even after writing ROM into donor PCB) it keeps saying it have 2 heads.
Tried to do RAM headmap, start with changed headmap and nothing works....

Any ideas??

It has 1 head. True, head map shows 2. Head map wont work.

I suspect SA.

I might help

i remember some of these had a memory allocation problem, they forgot to free a buffer under some circumstances, which resulted in consuming all the buffer allocation entries...
There were 2 solutions: correct the fw bug, or eliminate the problem which caused it to get fired.

Terminal logs mean Wrong PCB or used another case before

No, it was solved with the same and original PCB.

Not defect list, but firmware issue.
