[comp.sys.mac.misc] Floppy from Hell

gt4586c@prism.gatech.EDU (WILLETT,THOMAS CARTER) (08/07/90)

A friend of mine brought me a damaged disk to try to repair on my
IIci using MacTools.  I popped the floppy into the SuperDrive, and
nothing happened in a very significant way:  there was no noise from
the drive, and my mac froze up.  the cursor could still move, but i
could not access the menu, launch an application, nothing.  I had to   
reboot to regain control of the machine.  I put the floppy into another
friend's SE which also has a superdrive, and the drive attempted to 
read it and announced that the floppy was damaged and asked if i would
like for the system to try to repair it.

Why did inserting this Floppy from Hell make my entire system freeze?

Incidentally, my friend had a couple of other bad disks, and my drive
was able to figure out they were bad and repair them.  Also, the 
shutter on the Floppy from Hell seemed to slide OK and the floppy 
could be manually spun with no problem.  

Any guesses would be greatly appreciated.  Thanks
