Comment (by anevilyak):
I can't concur here, on my Corsair the results seem to remain as before,
which is to say the partition is still usable/readable, but there's no
obvious indicator as to whether the trim operation actually succeeded.
Steps:
- unmount partition
- dd if=/dev/zero
- mkbfs
- mount
- verify blocks are still generally zeroed apart from basic filesystem
structures via DiskProbe
- fstrim
- check blocks again - still zeroed. According to the drive specs, trimmed
blocks should theoretically return deterministic random blocks on read, so
this should theoretically rule out seeing straight zero blocks, but that's
not currently the case.
