for some values of 'work'. as its completely unaware of the internal
block remapping of the SSD, all it would really do would be to churn the
I've read the only way to reset the block remapping on most consumer
SSDs is to write all zeros on them, some vendors say twice. so, make a
full file system backup, zero the disk (maybe zero it again), then
restore that backup. NOW your data is all contiguous both in file
system logical space AND in remapped SSD block space.
