sorry, no LBC content, no vascular surgery content, no vascular lab content, but i just had a very terrifying experience and seem to have been saved by norton utilities- if you use a macintosh, you might want to read this use mac powerpc 7100/66, ran out of hard drive space, upgraded to quantum 1gig last january, found that apple hard disk formatter doesn't recognize quantum drive, had to have university repair service format drive- then things were fine until about a month ago, then noticed a "temporary items" folder in my trash, couldn't get rid of it because "in use", still there even when started with extensions off- didn't respond to truning off virtual memory either- the real problem was emergence of frequent crashes (often, but not always when connecting with netscape) and when i restarted, could not boot from hard drive, in fact couldn't see the hard drive! started from system 7.5 tools disk, the hard drive "unreadable, do you want to initialize? (that's when the terror really began!)- ran the apple disk first aid utility, found problems "but cannot fix", nevertheless, could now see the hard drive (terror abated briefly), but problem kept recurring- apple hard disk setup couldn't see the drive called northwestern consulatants a couple times, the first question was always "do you have norton utilities?"- didn't take the hint at first, thought this might have been revenge from lucas fan who might have sent a virus with some mail after i said a disparaging thing or two about lucas in my lbc mail, loaded current version of disinfectant anti-viral, didn't help i had backups (call me anal, zip drive purchased when i was anticipating installation of the quantum, among the 5 smartest things i've ever done)- bought norton utilities, ran the "disk doctor" from the emergency disk, found a bunch of problems, examples of the ones that seem now to be potential culprits: Scan Catalog An error was found in a leaf node in the catalog b-tree. Node 240 has an incorrect forward link. (5,4,1) Node #240 The leaf node was fixed. An error was found in a directory record in the catalog b-tree. The folder record for the folder, "GigaBrain", lists an incorrect number of files (or valence). (node 495) (5,7,8) Node #495, Record Offset 1 The leaf directory record was fixed. An error was found in a directory record in the catalog b-tree. The folder record for the folder, "Trash", lists an incorrect number of files (or valence). (node 419) (5,7,8) Node #419, Record Offset 1 The leaf directory record was fixed. fixed everything suggested by disk doctor, restarted, saw that pesky little temporary items folder in trash again, but this time, it allowed me to empty the trash, and now after several restarts (no subsequent crashes), everything seems to be fixed buying norton utilities also on list of 5 smartest things i've ever done joe (sphincters relaxed for the first time in a month) schneider Joseph R Schneider "You have a Lucas type 4 generator on a 12 volt system, and you know the British, they'd rather spend time glueing a piece of wood to the dashboard than get the electrical system right."
