disk fever

My PowerMac 5500 hard disc often lapses into a 'fever' (lots of whirring
and a hard disc icon flashing in the top left corner) which causes it to
virtually freeze up. I have recently wiped some redundant data and applications and transferred a lot of new data and applications from
another computer. What is wrong with my Mac?

Are you using sherlocks Indexing feature?...To find out open sherlock and under the find menu there should be an "index volumes" menu. Make sure youre NOT indexing volumes. You will also get disk activity like that if virtual memory is turned on in the Memory control panel. Set it to defaults.

The disk activity is not due to either of the suggestions made.
Have you optimized it or run norton on it lately?

If you are running Norton File Saver and have it set to scan after a certain amount of idle time, you will get this behavior.  The fact that you have a hard disk indicator in the left part of the menu bar suggests that this is the case.

To eliminate this behavior, open the File Saver control panel, select the Scan Schedule tab, and deselect the "after N minutes idle time" checkbox.  Do the same in the Update Schedule tab.

You can also stop this behavior by holding down the "bypass scan/update" hot key, configurable in the Hot Keys tab of the same control panel, which defaults to the Option key.

Because your disk light is flashing so crazily (word???) and you hard drive spinning so much, it sounds as if your hard drive is frantically searching the disks for the information.  Dumping files and applications onto a hard drive and ESPECIALLY pulling some at the same time, makes a mess of the organization of you hard drive info.  You need to run a utility to check your system for unnecessary files and THEN optimize your system.  Try this and see what happens....  :)

Did as boostra suggested with Nortons but discovered I had a version which was incompatible with my current system. I removed it but disc hyperactivity is still there. Comments from redironman makes me think
I have a mess on my hands and need someone who knows more about these things than me to fix it up. I will get someone to look at it. Not really sure how to grade as I am a novice at experts exchange, and weed, boonstra and redironman were all helpful.
If your Norton is not current, suggest you remove all Extensions and Control Panels related to Norton and reboot.

I'd make certain File Sharing is off.

I'd make certain your disk is not full, deleting unnecessary files until you have at least a few meg unused.

Then suggest you run Disk First Aid.  DFA 8.5.5 is the most current, but you can get 8.2 at:

Good luck.
