Howdy! I need to determine if a floppy is write protected from MSC. At first, I just fopen()'nd a file on a write protected floppy expecting the returning FILE *fp to be NULL if the disk was write proteced. Well, that did'nt work, but you probably guessed that by now 8^). Then I broke out Norton's "Programmers Guide" and tried the ol interrupt method. Ya see I got this idea to read in a sector, then try to write it back out, and then check the disk status afterwards. Messy, but kinda fun I thought. The only problem with this apporach is that the returned values are inconsistent. (Yep, I tried both the int86() and the dosintx() after I learned the difference between the two). At this point I need some guidence. Any one know of any method that works? I dont care how messey, so long as it works. thanks stergios marinopoulos S&M Engineering % UUCP: !decwrl!rocky.stanford.edu!stergios % % ARPA: f.flex@othello.stanford.edu % % USnail: Crothers Memorial #690, Stanford, CA. 94305 % % Pa Bell: (415) 321-7678 % -- % UUCP: !decwrl!rocky.stanford.edu!stergios % % ARPA: f.flex@othello.stanford.edu % % USnail: Crothers Memorial #690, Stanford, CA. 94305 % % Pa Bell: (415) 321-7678 %
