1. What is the most effective non destructive way to erase or prepare a SSD drive for an openSUSE (LEAP or TDE) installation?
There is a "secure erase" function in hdparm, but I guess it is equally bad.
I would simply use gparted and create a new, empty partition.
The trim method mentioned by Michael, I will have to read about it.
I forgot there is a way with dd, which is to zero a few sectors at the starts, where the GPT table resides, and a few sectors at the end, where there is a backup copy exists. However, this is what gparted does, more or less (replacing with a new table). However, I do not know how to calculate the exact sectors to erase. -- Cheers / Saludos, Carlos E. R.
