one more thing. I have tried to open J3 in one of my drives but it did not 
help. Maybe the sensor doesn't work in it.

Subject: 1541C reset behaviour

Hi all,
I've got a 1541C :) It looks like the original 1541 but in a white-ish case.
It does seek to track zero every time the connected C64 is switched
on. Is this drive supposed to do that? Neither the original 1541 nor
the 1541-II do that (also it seems it wants to read something from the
disk?).
I've upgraded the firmware from 251968-01 to -02 since the original
one was not compatible with some demo fast-loading code (like lunatico
from LFT).
Is it worth to open J3 that's supposed to make the track-0 sensor work?
The drive appear to read/write fine other than the strange (to me)
thing at C64 power on.
Thanks
Frank
