Storage? I am Storage!
Yes, really. It started to happen after I made a small change a few days ago.
I have 2 HDDs (a WD 80GB JB, and a Quantum FB+LM 30GB), each the master (and sole) drive on it's own channel on a Promise Ultra 100. The opticals are on the MB IDE ports. I had the HDDs connected to the center (slave) connector of the Ultra-ATA cables for convenience reasons; after reading a thread at SR, I put the HDDs on the end at the Master drive connector. I've had this weird noise since then.
It sounds like the noise diesel engines periodically make, like a sneeze. Or imagine a hot griddle; wet you fingres under a running tap and then flick the water from your fingers on to the griddle. What do you hear? A big hiss, that slowly dies down as the water evaporates. The pitch of the sound goes down in the process. That's exactly the sound I'm hearing. And no, my rig isn't water cooled!
The noise doesn't happen with any consistency with respect to time; I may not hear it for a whole 10 minutes, or I'll hear two within one minute. I've got the side panel off and tried to listen to isolate it, but I can't tell. I've run the respective diags on both the HDDs and they passed with flying colors. At this time, I'm not able to troubleshoot by disconnecting things one at a time; I've got things running that can't be shut down.
MB is a Tiger 100, running two FCPGA P-3-800s in slotkets. The case has 3 fans in it, one of them in front of the HDDs in the drive cage. It's not the CPU fans or the other two fans; I've checked with a flashlight. I can't check the HDD fan because I can't see it till I remove the HDD cage.
Any ideas? :-?
