I have a problem using an Optical Floppy from a Motorola
68030 Micro under VxWorks 5.1 Operating System. The problem is 
the following:

I have to develop a program in ADA to write and read from an
Optical Floppy that is connected in a SCSI port "/sd0/".
I thought it'd be very easy using the ADA procedures OPEN,
CLOSE, READ and WRITE but I have encountered that I cannot 
control if somebody removes the floppy when a write or read
operation is running. I think that a DEVICE_ERROR exception
must be raised but it doesn't happen.
Perhaps, the Operating System creates a temporary file to 
write an read, and when I CLOSE the file the system phisycally
writes data in the floppy, but if this idea is right, Why isn't 
any exception raised when I CLOSE the file after removing the floppy??

Any suggestions??

Thanks in advance..
