Using D4. How to stop I/O Error 21 when trying to access removeable media when no media present (i.e Floppy Drive - no disk, CD - No Disk, ZipDrive - No Disk). This is driving me mental. I have a project with the similar components and code that I worked on in D2. If I run the EXE from that old project I just get a message box saying Invalid filename.
Please help it's doin my ed in.
