Device name.

Pointer to variable that will receive the return error code from this function.

FS_ERR_NONE

Notes/Warnings

  1. Function blocked if a volume is open on the device. All volume (and files) must be closed prior to initializing the partition structure, since it will obliterate any existing file system.
  2. Device state change will result from device I/O, not present or timeout error.
