Just set up my O2 with a fresh install of IRIX 6.5.30 and a Compaq SCA drive taken from an old server of mine, and I've been experiencing this constant repetitive disk activity even when idle. It's almost exactly every second it makes two clicks out of the hard drive. I'm wondering if this is a known thing IRIX does, such as flushing logs every second, or something peculiar about my setup? You can hear audio of it at https://ckits.ca/files/Irix_disk.mp3 or https://twitter.com/ChartreuseK/status/1...01028?s=20

I'm wondering if this is IRIX flushing logs and if it could be tweaked to increase the period to a minute or more, or saving certain ones in a ram drive and not bothering to flush). Or if there's just something wrong with my setup and I'd be better off doing another clean install. 

Someone on twitter advised me that it could be related to swap, but even disabling the swap device `swap -d /dev/swap` provided for no change in behaviour.

If it's not normal I'll see about grabbing a different SCA SCSI drive for it, and hopefully one with a quieter seek anyways. However I don't remember it doing this at any time during the install process, only after booting up into IRIX so I don't believe it's a dying drive.
