Since DECUS seems to cater to people running DEC software (and UNIX doesn't qualify as DEC software, since it takes less than 14 statements to open a file), this might not be the forum for finding out about RT-11. Good luck. You'll probably need it. Jeff Bowles Lisle, IL

It has been my experienct that physical cleaning rarely restores bad blocks on the disk. Often a flakey drive is at fault. Since the track positioning info is stored on the same surface as the data, a bad drive can currupt the disk. The only cure I have found(which works about half the time) is to write a program that forces a write to each block on the disk even the bad ones. If that doesn't cure the problems, just use it for a frisbee, as I can't find anyone who will reformat old packs. Michael G.
