DMEDIUM_REMOVE [(#channel)] or


Location SMSQ/E v2.73+

This function returns the value 1 (true) if the medium on which the specified file or directory is located (or to which the specified channel is open) is a removable hard disk. Otherwise it returns 0 (false). If no parameter is specified, it looks to channel #3 (or #1 if #3 is not open).


This function does not appear to work on Falkenberg hard disk interfaces where it always returns 1.


DMEDIUM_RDONLY allows you to check if a disk is write- protected. There do not appear to be any ways in which you can check if any channels are currently open to the medium (ie. whether it is safe to remove the disk), except for listing all currently open channels, see CHANNELS.
