Function

Checks medium

Description

This function checks the status of the drive's medium. It reads the DISK-ID and compares it to determine whether or not the medium has been exchanged. If the medium has been exchanged, this function makes all file handles unavailable, sets the current directory to root, and returns MFS_ERR_DISKCHANGE.

Main errors

MFS_ERR_NO	Normal termination
MFS_ERR_DEVICE	Device error An error occurred in an internally called Leo function. Since a Leo function error is stored in the variable mfsError, check this variable to perform processing.
MFS_ERR_DISKCHANGE	Media exchanged The media has been replaced by another media. If a file is opened, close it and begin the process for opening the file again.
MFS_ERR_NOTMFSDISK	Not an MFS-format disk The disk ID's disk use is not 1.
MFS_ERR_VERSION	Different version disk
MFS_ERR_HEADER	Header error The header area is corrupted. If it is the RAM area, try to repair it.
