Using the 29PIN LIF connector on the MZ-RPA1280 as an M2SATA

[Neo0]

Hi,
I have the misfortune to have a drive like the MZ-RPA1280 for the SONY VAIO VPC-Z21 series laptop and it has come to an end.
However, as it turned out, there are craftsmen in the world who make m2SATA from these drives using soldering and separate wires leading from the new m2sata drive to their old MZ. It looks something like this fuzzy photo (see attachment m2_lif.jpg). Most likely they did what they did in this old thread: https://forum.hddguru.com/viewtopic.php ... ile=mobile
If I understand everything correctly, then I need to do as I painted here (see attachment m2_disk_edit.jpg). But one question bothers me: how to completely turn off the 3.3V (or maybe 5V) power of the old MZ drive in this case? Which tracks need to be cut or will it be enough to unsolder any element so that only the new m2sata drive is fed? Did I understand correctly that the tx / rx sata connectors on the backside I leave as it is?

P.S. Explanation for post above: Data on the disk is not needed, but I would like to continue to work with this laptop. The question is how to change ssd here to something more stable and standard?
