Hello, Yesterday, Techtool checked my OS 10.2.4 Hard Disk and under the Multi testing it was stuck by Volume structure, sub "Catalogue file". I waited for 45 minutes and nothing happened, I skipped the Catalogue File and the test was further OK without any difficulties. I am not a computer freak, is here maybe something significant wrong, I checked with DiskWarrior and all the directories are OK. Can somebody help me me to straiten this problem out. Thanks in advance, Ernst.
