The Blue Chip upgrade doesn't require returning your old CPU module which is a plus, and for owners of cacheless PB G3/233s, it's the only 3rd party CPU upgrade option. I hope to have a review sample in the future to test for reliability and performance. [*Update* in January 2001 I posted a review of the Bluechip G3/500 tested in my PB G3 wallstreet. The CPU ratings database also has reports from owners of the Bluechip upgrades.]

" Hi Mike!
Saw your post about Diskwarrior and overlapped files the other day, and finally have a chance to share my experience with the same problem. Here's the dialog between me and Jorg at Alsoft:

Question_or_Problem:
Disk Warrior has been running 13 hours now, and has found 3986 overlapped files so far. Any idea if it's worth continuing the run?

(My teenaged son was on my machine, screwed something up, then tried to fix it with an old Norton Utilities version 4 CD). Internal is unbootable; Finder says it "cannot be found."

Mac OS Version: Mac OS 8.6
Mac Model: G3 blue+white
Mac Processor: G3 (PPC 750)
Mac RAM: 256

Whether you continue to allow DiskWarrior to run or not is up to you. It will eventually finish the job and give you back a working directory. If you need the computer right now and all the files are backed up then you may want to stop the process. Remember if you stop it and then decide to restart DiskWarrior it will take another thirteen hours to get back to this point. If all the files are backed up it would be more efficient to reformat the disk and restore the files.

If you decide to continue on what will happen is that DiskWarrior will give you a report. At this time you can look at a preview disk and if you have the capability you can back up the files from here. If you go on to replace the directory what will happen is that DiskWarrior will separate the overlapped files. Let's say file a and file b are overlapped, DiskWarrior will copy file b to another spot on the disk. With 3986 files that could fill up the disk. At that point you will have a working disk and you can most likely restart the computer from the disk but there will still be overlapped files. If this occurs copy some of the files off the disk then trash those files and run DiskWarrior again to allow it to finish unoverlapping the files.

(Mark's comments later-Mike)

... Disk Warrior ran 70 hours and then it fixed every damn thing!!!

Actually, it blew off while repairing the overlapped files after replacing the directory, but I found an alias in Damaged Items that was 2GB in size, trashed that, reran DW, and it adjusted disk space used to the correct 5.5 GB of 6GB disk, pretty much ignored the overlapped files thing, and finished in just a few minutes.

I'm a very happy camper, especially since the boy finally admitted that he'd run Norton 4 not just once--but SIX Times!

Thanks again for your help, especially the sentence: "It will eventually finish the job and give you back a working directory." There were many times between 11:21 p.m. Thursday and approximately 9 p.m. Sunday, when as I watched the "overlapped files" count slowly rise through the thousands to a final count of 10,756, that only your words and a stubborn disposition kept me from just reformatting the drive.

I've had Diskwarrior save my bacon many times, but it never took more than a few minutes until the Powerbook HD was trashed. I consider it one of the 'must-have' Mac disk utilities.

" Mike:
A comment regarding Debra Dnahouraii's Orb problems: it sounds suspiciously like faulty termination. You can't just simply trust that the built-in termination works properly.

In my case (Oct. '99 SCSI Orb), the drive would not operate at the end of a chain w/other devices, and when connected alone, would produce numerous disk errors.

I then attached an external active terminator, and the drive has worked properly since. Disks which had previously produced errors now work fine.

My conclusion is that the Orb SCSI termination is faulty, and you should presume that it has none, and use your own external termination.

Something that occurred to me is I wonder if that Mac model (6500/300) supplies terminator power to the bus (not sure if the drive does) but if not that would only make matters worse I think. There's an older page here with SCSI ORB drive owner comments from last year.
