Most device access functions can return any of the following device errors:
FS_ERR_DEV_INVALID_LOW_FMT
Device needs to be low-level formatted.
FS_ERR_DEV
Device access error.
FS_ERR_DEV_IO
Device I/O error.
FS_ERR_DEV_NOT_OPEN
Device is not open.
FS_ERR_DEV_NOT_PRESENT
Device is not present.
FS_ERR_DEV_TIMEOUT
Device timeout error.
Each of these indicates that the state of the device is not suitable for the intended operation.
