Struct FsStatusFlags 

pub struct FsStatusFlags {
    pub dirty: bool,
    pub io_errors: bool,
}

FAT-resident volume status flags read from FAT[1].

The FAT spec dedicates two high bits of the cluster-1 entry to volume hygiene: one for “clean shutdown” and one for “no I/O errors during last mount”. Both bits are cleared when something is wrong. This struct inverts that polarity so a true value always means trouble.

FAT12 has no spare bits in its packed 12-bit entries; the spec doesn’t define status flags for FAT12, so a FAT12 mount always reports dirty: false, io_errors: false.

Fields

dirty: bool

true if the volume was not unmounted cleanly last time.

io_errors: bool

true if I/O errors were reported during the last mount.
