Hi folks, After a disaster with hdparm security-erase before an action to align the partions and the filesystem properly on an ssd, my ssd became fully uncommunicative. Now to my opinion,it is desirable that the opensuse partitioner has an ssd option to align partition and filesystem properly on this this type of devices. Is this a good idea and a reasonable expectation ?

Thanks, Hans
Are you guys sure this doesn't already work: If yast partitioner / installer is not following this logic it's a bug: 1) Default all partition starts to 1MB boundaries. (That is ignore cylinders, etc.) 2) Get physical sector geometry from block subsystem. If it does not align with 1MB, then move the starting sector to align. So a 4KB physical sector works fine with 1MB. So does a 128KB erase block on a SSD. But a raid5 would typically not align, so if mdraid is properly reporting, yast-partitioner should override 1MB to align with the raid stripe. Again, if the above is not true, its a bug.
