When I finally recovered from my monster crash of Dec 17and after an "Write all zeros" Erase I then installed 10.4.11 on my 250 Gig and partitioned my 500 Gig to 420 and 80 then realizing that the 500 Gig may have had physical problems I did a "Write all Zeros " erase on the 420 and 80. That gave me a 420 Gig and a 45 Gig. Many bad sectors on the 80 gig. I probably should have Nuked the whole 500 Gig and then partitioned but by then I was out of patience. Then I used used SuperDuper to do an incremental back-up on the 420 Gig and 45 Gig. I figured from what the SuperDuper notes said that it would up-date all that was different on the Target. Since there was nothing on the the Target I thought that would mean everything on the 250 Gig would be moved to the Partitions. Also Part of the instructions on SuperDuper says leave the Target Bootable after an Incremental Up-Date. When finished I had two Bootable partitions that were clones of the 250 Gig drive. Now I run MacJanitor on the 250Gig and incrementally back the partitions up nightly. It takes about six minutes for about 9.25 Gig's with my Dual 500 GigE to increment each partition. I do have a question though. When I run MacJanitor on the 250 Gig and then Increment the other Volumes does the Clean-up on the 250 get properly transferred to the other volumes? I do leave them booted all night in hope that the Cron tasks will clean them. But not too sure about all that.
