Might be a probability issue. For the 250 GB case I did in total about 200000
truncations on about 250 files and found in the output file 8 and 13 corrupt
blocks (I only kept detailed numbers for two cases). Reducing the block size
might "help" by increasing the number of I/Os.
I can't test your script right now, the disks are all busy with some long
running experiments. There should be another one just back from RMA on my desk,
so I can try it tomorrow when I'm back there (was travelling for a week).
What do you do on the remaining space of the SSD? Try putting a file system
there and fill it with something so that the SSD is 99% filled so it can't that
easily remap the blocks you are writing to.
