I made a tool using Turbo C that copy a floppy disk into a file by sectors and
viseversa. I have a little problem when I try to restore a floppy disk from a file.
The problem is that DOS do not refresh its internal directory table. That's mean
that I need to open the floppy disk door to tell the DOS to read again the new
directory. I am overriding the DOS function calls to access the disk. But also
I made a version that use Absolute Disk Read/Write DOS internal routine and
doesn't work. Do I miss an interrupt routine to update the directory???
I try almost everything. Help!!!

Thank you,
