So i have two 15k Worldisk (Fujitsu) 36gb drives in my O2. When I power the machine on and let the drives spin up they will start to make a ‘whoom-whoom’ sympathetic vibration humming sound as the revolutions of the two drives are near, but probably not 100% identical. Each drive on it’s own is perfectly fine. Any fix for this? (I doubt it).

i don’t really want to invest in any more scsi drives. I do have a 146gb seagate but it gets blistering hot! I would just pull one of the drives but it has most of my application archives.

You might try some mechanical decoupling from the drive tray / chassis; instead of using screws to fix the drives, try some rubber or sticky tack? The low frequency vibration is the beat frequency caused by the slight differences in their vibrational frequencies 😄

Another idea would be to put one in an external enclosure to separate it a bit.

Another question - I have a spare 10k 18gb drive that is a bit quieter, Compaq brand but I’m not sure Compaq made scsi drives. One of ICs on the back is Agere Seagate, is there a way to find the original brand / spec of the drive?

…and I remembered - the 146gb Seagate committed suicide by seizing up from heat. 😁

I think Compaq and later HP rebranded Seagate drives, as indicated by that chip. Does the model number on the label indicate anything?
