I am writing an application using Borland C++ Builder Version 6. The application will run on a computer that uses the Windows XP operating system. Data is transferred on and off of this computer using a 3.5" floppy disk. I would like for my application to be able to detect when a disk is inserted or removed from this drive. I would prefer to accomplish this without polling the floppy drive since that will start the drive motor each time. My application needs to run 24/7 for several years and I'm concerned that starting the motor that many times will wear it out. Do floppy drives generate events when media is inserted or removed? Is there a way to detect these events? Thank you. Back to top Remy Lebeau (TeamB) Guest Posted: Tue Jun 21, 2005 5:46 pm    Post subject: Re: Detecting Floppy Disk Media Change.

Is there a Win32 function to check whether a certain drive exists ? Don't those sticks just add a "removable" drive to Windows when they are inserted ?

Take a look at the RegisterDeviceNotification function. Back to top Jonathan Benedicto Guest Posted: Wed Jun 22, 2005 2:37 pm    Post subject: Re: Detecting Floppy Disk Media Change.

There are several ways to do that: 1) GetDriveType(). 2) GetFileAttributes/Ex() 3) IShellFolder::ParseDisplayName(). 4) Probably several others that I am forgetting right now... Quote: Don't those sticks just add a "removable" drive to Windows when they are inserted ? I cannot answer that. I have no experience working with memory sticks. I would imagine that the reader device adds a new drive letter when physically installed on the machine, so that the drive letter is always available, and then simply mounts the file system to it when the stick is inserted. That is how CD/DVD andZip drives work, for instance. Gambit Back to top Jonathan Benedicto Guest Posted: Wed Jun 22, 2005 8:51 pm    Post subject: Re: Detecting Floppy Disk Media Change.
