I am experiencing intermittent disk accesses on my Mac Plus for which I have
no explanation and which I fear might belie an infection of some sort. The
accesses happen at fairly regular intervals of about 5 mins. and seem to be
independent of the current application.
I am running system 6.0.2 on a stock Mac Plus with a Seagate-based Ehman
drive and a Pract. Periph. modem as my only peripherals. I have numerous
CDEVs and INITs installed, but I can get this behavior even after emptying
all of these from the System Folder into a separate folder and re-booting.
I run Disinfectant on all software I download and occassionally on the whole
hard drive, so a viral infection seems unlikely. Perhaps this behavior is
part of the normal functioning of the drive or the System?
I have looked around for a utility which would give me some information about
the disk access (read/write, where it's coming from, etc.), but have found
nothing appropriate.
Any ideas? I will post a summary of the results if I figure out what is
going on. Thanks.

The This is probably normal. Seagate drives "recalibrate" every few minutes for some reason, and you can hear this since the seek is rather loud on these drives (it sounds like a couple of seeks). I think they do this to catch any thermal expansion/contraction problems in the head arm and the disk itself. BTW, if these sounds "belied" an infection, they would be showing it to be not true :-) Eirikur Hallgrimsson eh@ddif.enet.dec.com
