Yes, agreed. It's not the idea of a driver that I don't like; it is making it available through the command-line that worries me. This would be unlike all other "filtering" options (copy-on-read, I/O limits, dirty sector tracking). True, there are blkdebug and blkverify but those are for debugging only. Paolo
