the failed byte counts in the log look rather random, which usually
means the hardware setup is failing. Did you try to read+verify with
this setup? only if reading is 100% reliable, writing will work.

Do you have the plain chip connected or is it already soldered to the
board? If the former, make sure to connect all input pins, i.e. /HOLD
and /WP too. If the latter, power supply can be a problem; using the
regular laptop PSU works best (might have to get it into a wake-on-lan
state). Also, the T530 lacks pull-ups on the /CS lines of both flash
chips. If that is the case for the T430 too, idk, but if, you should
make sure that the /CS of the chip you _don't_ want to access is
pulled high.

Hope that helps,
Nico
