    How to disable zero filling of newly allocated files?


    Hello!
    This is an issue for ages. Apparently windows writes zeros by default for all allocated files. Particularly noticable, when downloading with bittorrent, where the app hangs and the hard drive becomes unusable for quite a while.
    But it's also a problem more generally. Any such allocations will double the wear on HDDs and particularly SSDs, apart from taking twice as much time.
    Any way that I can set windows to don't write zeroes when allocating files?

    Double check if you have trim enabled, open Admin command prompt and type:
    fsutil behavior query DisableDeleteNotify

    DisableDeleteNotify = 0 : TRIM is already enabled
    DisableDeleteNotify = 1 : TRIM is not enabled

    To enable SSD TRIM support, type:
    fsutil behavior set DisableDeleteNotify 0

    That's all fine, but it's not relevant to what I asked.

    My answer does apply if you use the SSD.
