  1. ECC memory is supposed to be able to autocorrect on the fly 1 bit of corrupted data in memory. With ECC then only HDD corruption could be considered (i do not consider corruption from cpu). For only HDD data corruption, then snapraid does answer to the problem as long as it s a per request check. But snapraid doesnt do it every time the file is opened for example, only when the bacth scan will be launched (though its enough in my case). I was more wondering if scanner would be of any benefit if not using ECC memory compared to the case where you could use ECC memory ... Or another way to say it : if scanner does allow me to use non ECC memory with a result as good as if i used ECC memory without scanner, then i would be interested because chossing ECC memory does limt a lot the choice of other components … unless price doesnt matter

  3. Lets say i m using drivepool for data only, and not on the drive that is used for the OS installation. Now lets suppose i need to change both the motherboard and the drive on which the OS is installed, without being able to preprare anything (HDD of OS + motherboard faulty). Once the new motherboard and OS is installed, what would be (if any) the way to recover the "old" ? is possible without the need of balancing any data between the disks that were incolved in the pool, in otherwords, with every files remaining on the drives where they actually are
  4. Considering i will use snapraid and update parity drive + checksums everry night. In what scenario would Scanner be of benefit to me if : 1/ i am also using ECC memory 2/ without using ECC memory By scenario, i mean in what practical cases it would recover from or prevent corrupted date ? (i just want to measure the possible benefit before adding a layer to my NAS media center). Also : when does scanner check the parity ? anytime the file is open ? and or / scheduled ? and or ?
  5. Hello, I m trying it right now after being disappointed by space storages lack of easy customization. I will use snapraid along with drivepool, for info. My concern is more about the project being still in developpement or getting abandonned progressivly by its author, as i have seen very few communications (not to say none …) about incoming features or bugs being fixed / improvements.
