But if you were running a REPAIR and force quit - well you might have quit just as the program was over-writing some important information. Think about it - while repairing, data is stored in memory and data is overwritten. Should the program quit at the wrong time a repair would be incomplete - that could be disaster. That might be your experience. I've given the new TechTool two drives that no other program had repaired and it repaired one of them. I also gave it two drives that Disk Utilities had pronounced fit and it agreed with both. A 4 drive test ain't much but I can report that so far it has done no harm. david =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= "When will the public cease to insult the teacher's calling with empty flattery?
