On a single floppy disk, I had two folders. One of them contained 3 MacDraw images. I selected the first (one click on icon with mouse) and used the pulldown menu to "print" (not inside the MacDraw application). It seemed like a nice shortcut, until it crashed. My floppy was in the disk drive when all this happened. The mouse froze and there was no keyboard response, so I powered down (the floppy ejected) and then powered up. I rebooted the system from the hard disk system floppy and then attempted to read my original disk. The error message was as follows: System error. This disk is unreadable. Do you want to initialize? I answered "EJECT." I tried to get some help from the systems people around here but we don't have any utilities to read unformatted disks. I suspect that one of the files on the disk is corrupted (the one I tried to Print), but I don't think all of them are. Does anybody out there have a utility that either: helps read unformatted disks, or finds the next file on the disk? Even a diagnostic utility that can explain what's wrong? I'd rather not through it away. Thanks in advance, Julie A. Harazduk {ihnp4|seismo}!philabs!jah

The problem of unmountable disks caused by a crash can usually be fixed by using a program like Copy ][ Mac to sector copy the damaged disk. Usually, the error status indicator on Copy ][ Mac shows one or two sectors have been clobbered. Copy ][ Mac reacts by writing out zeroes to the respective sectors on the target disk. 9 times out of ten you will find that the duplicate disk (with errors removed) will mount properly. jason ( baron@runx.oz && jasonh@psych44.su )
