I have an iMac DV SE running OS 10.2.8. I would like to try a few things before resigning myself to pouring yet more money into this computer. I can't afford a new computer and this one has already been given a new motherboard and logic board. I am sick of giving it gifts, so don't want to give it a new drive unless I absolutely have to. The problems are many, but I think if I could just repair permissions, things might improve. However, I cannot repair permissions at this point because the hd icon does not appear as an option in disk util. Nothing shows up at all. So, I tried repairing permission on console with sudo diskutil repairpermissions / which gets me this message: DiskArb couldn't be activated! I booted from the install CD, and ran disk util which got me this message: Volume check failed. Invalid parent CName in thread record. Missing thread records (with a list of about ten missing records given) Tried single mode fsck -y at console, get the same results. Safari disappeared totally after a crash. In the dock and in the applications folder, there are generic folders marked 'Safari' but they are empty. A 'find' search finds nothing except the Safari crash reports, but the final and fatal crash isn't listed. I thought this might mean a bad block, but instead of just being gone, the empty generic folder is there instead. I logged in as another user, same problems occur. Attempts to install any new programs (such as Macaroni) in the hopes of running permissions repairs another way fail with an error 32, broken pipe I wonder about Cocktail, whether it might be an issue here, I installed it recently and was using it to repair permissions, etc., but now the trial period is over and suddenly I cannot access the drive to run permissions through disk util. I ran sudo sh /etc/monthly, weekly and daily checks manually on the console. The results from the monthly ones are bizarre, and QT gets mentioned a lot. I could post it if it might give a better idea? Perhaps the weirdest thing is, other than these events, the system is actually running quite nicely, it isn't slow, it isn't having unexplained crashes or freezes, etc.. How bizarre is that? Thanks, if you can help with some tips, it would be hugely appreciated. I feel like a real dork for signing up to a new forum and immediately tossing out a big whackin' problem like this, but I am quite new to the whole Unix-based way of life. I love it, but am not very efficient at troubleshooting things yet.
