Sounds like dry bearings

Original equiptment in a beige G3 MT vintage 1998

I was reading email when suddenly the hard drive started to make a grinding noise. I closed all the open applications, then opened a few, didn’t seem to effect it as the noise continued. I read Kris’s last post in Dust in the Wind and then it stopped. Noise lasted about two minutes.

On a rare occasion in will make short noises when seeking on the drive, but never that loud, long, or in idle mode. My thought’s on this is a lizard, ant, or just dust got in there dragging a bearing down, or......... it’s time to R&R the hard drive.

Any thoughts?

My superdrive started making infrequent clicking noises which became steadier. It died last Thursday.  My new drive is due on the 18th.  I would suggest backing up your drive while you still can.

Thanks for the heads up Gmann, done!

Oh wait, it might just be the fan! The noise returned for about a minute, it sound almost tinny, high rattle, thin aluminum, and I think I can still hear the Hard Drive as the noise fades away. It’s coming and going now, it start to rise in noise level, RPM? then slowly fades to silence. maybe I should replace the fan also, or in lieu of?

Where that WD40? Marvel Mystery Oil? 3 in 1 Oil? Never Seize?

Pack them bearings........
