what does „other chips work fine” mean? With the same WD HDD setup? Or on other
Which programmer are you using?
Could you provide a logfile with the output of flahrom when trying to detect the chip and
running with the –V parameter?
Will supplying power through 3.3V Vcc and SATA
connector at same time fry the chip?
It should not. If SATA is 3.3V as well (not sure if SATA uses 5V?) and you connect
the Ground there should not be fried nothing. But on the other hand I´m not sure if this
is your real issue. Better you do steps mentioned above first.

Betreff: [flashrom] HDD in-circuit reprogramming
I need to reprogram the firmware on a WD HDD with SOIC8 Winbond chip supported by
flashrom. I tried reading in-circuit but my programmer does not detect it (other chips
work fine). Probably other components are drawing voltage so I disconnected Vcc and tried
to power it through regular SATA connectors which didn't work. Do you have any
recommendations how to workaround this issue? Will supplying power through 3.3V Vcc and
SATA connector at same time fry the chip?
Thanks for your help
