    An interesting bug, but to be fair, /f should be used only when needed, not at random. I use just "chkdsk /scan" for the maintenance. F parameter can take several hours on HDD, it is obviously not healthy for SSD.

    Armed with a Macrium Reflect image in case of the worst, I tested this on one of my SSD machines. Nothing bad happened....

    Running chkdsk switches on a SSD appear to be controversial:

    Is it possible the issue applies only to GPT/UEFI disks, not MBR? I only have 2 SSDs on Win10 Notebooks, both as MBR, and 1 on a Linux Mint install.

    The machine I tested it on (and found no issues) is UEFI/GPT. Specs are listed on WindowsQ as my 'System Two'.

    It is very strange that a particular Win 10 ver with a particular patch can affect a old task as chkdsk c: /f, specially because the task runs under WinRE after boot, but.... as it's Win 10 I can expect anything.

    In part of that BornCity blog,
    somebody had reported that the fault only happened on computers with m.2 disks not other SSDs.
