I accidentally double clicked the file "/NextLibrary/References/Webster-Dictionary/Dictionary.nxbf" which is about 20 megs big. And of course it invoked Preview which was loading for more than 5 mins. I then used 'Processes' in WorkSpace to kill that process. A Core dump was generated which was about 3 megs; I deleted it but I also found out that 6 Megs out of 406 of the hard disk space was gone!?? I then login Root and do the following in the Shell: /*****************************************************************************/ localhost# fsck ** /dev/rsd0a ** Currently Mounted on / ** Phase 1 - Check Blocks and Sizes ** Phase 2 - Check Pathnames ** Phase 3 - Check Connectivity ** Phase 4 - Check Reference Counts UNREF FILE I=27266 OWNER=root MODE=100644 SIZE=1180 MTIME=Jun 2 20:18 1991 CLEAR? y UNREF FILE I=61035 OWNER=root MODE=100666 SIZE=9 MTIME=Jun 3 17:12 1991 CLEAR? y ** Phase 5 - Check Cyl groups BLK(S) MISSING IN BIT MAPS SALVAGE? y 12310 files, 197509 used, 204744 free (744 frags, 25500 blocks, 0.2% fragmentation) File system not may not be clean! Run fsck again to clean. ***** FILE SYSTEM WAS MODIFIED ***** ***** REBOOT THE SYSTEM (NO SYNC) ***** localhost# /*****************************************************************************/ I've tried <1> reboot -n. <2> switch from NMI to mon NeXT> and reboot the system. <3> Alt-Cmd-* To reset the machine. <4> run fsck again to clean the File system and then reboot. ......... many trials + phone calls. The result remains the same, Everytime I run fsck, it says the same errors. And the missing 6 Megs never comes back. The file system was never fixed. --- The buffer cache always rewrited the superblock, I guess, even I specified the -n (No Sync) or or reboot the system from Mon. I've been looped around by the NeXT support by asking such questions that few people ever experienced. Can anyone find me back the lost 6 Megs? -Gary Chang NeXT-Mail Addr: garyc@robbie.acns.nwu.edu E-Mail Addr: garyc@eecs.nwu.edu
