Perhaps, perhaps not. Yesterday when I should restart the AMD 64 I placed my hand on the chassis and could feel some vibrations as lather disappeared. I couldn’t hear if it was the fan or the disc. That is my Achilles heel. But all other works well and I have not got a feeling or message there is something wrong on that computer.

If the disc should go crazy and the read/write head should begin go very fast fort and back I can’t think it should cause heavy vibrations or perhaps am is wrong? And the fan should only give vibrations if it runs in unbalance for example.

To be honest I have zero experience of accidents with discs and fans. My experience is discs of today and even 10 year back is very reliable and don’t broke down after 5 year. On my Intel PII I have an 8 year old disc as never failed and yet it worked hard running MoneyBee.
