I'm no expert but I think fstrim is no help here - it merely reclaims free space on a disk, but raw data is still accessible. At least can be if disk does not implement DRAT (Deterministic Read After Trim) (read of zeroes that is).
But better safe than sorry, right? So maybe we should issue fstrim after all.
Yes, also trim very useful on ssd =), But i don't check does this helps or not, this is only theory. -- Vasiliy Tolstov, e-mail: v.tolstov@selfip.ru
