disk repair utility (was kernel panics...)

OK, now that my memory has been jogged by inserting the Jaguar (10.2.3)
installation disk, there is a Disk First Aid program in the Utilities
directory. I didn't run it because it's a classic app and thought it
might be incompatible with a system with OS X already installed. I
don't see any other disk repair utilities on the CD.

Is it a good idea to run this utility, and is it preferable to fsck?

BTW, the system seems dramatically more responsive since I booted after
attaching a different mouse and disconnecting the SCSI scanner and zip
drive. It's too soon to tell if one of these devices had something to
do with the panics, but it seems like a good sign.

No, Disk First Aid won't do anything when run in Classic on Mac OS X.

For Jaguar, look in the Utilities folder inside the Applications
folder. There is an application named Disk Utility. Run it, click on
the "First Aid" tab near the top of the window, click on a disk icon,
and click the Verify Disk (or Repair Disk) button.

Note that Verify Disk and Repair Disk merely run the appropriate fsck
program (typically fsck_hfs) for the disk you choose.

Thanks for the info. I did run that Disk Utility before looking on the
install disk. Disk Utility says that to verify/repair the startup disk,
you must boot from the OS X install disk and run the Disk Utility from
the Installer Apple Menu. However, it also says that the startup disk
is verified/repaired at boot time (as would be expected with a
Unix-based o.s.). My system has a single hard drive with a single
partition, and it appears that the available disk repair function is
being run automatically and there are no further disk repairs that might
help eliminate the panic problem.

Yes, that is what is says alright, and yet I've often found that running
fsck in single user mode finds disk problems, so I'm not convinced that
the OS really checks the disk as throughly as it could. Sometimes, as is
usual for unix systems, you have to run fsck several times before no
more errors are found.

(Disk utility when run from the installer just runs fsck, I believe).
