Apologies if this is something that's already been discussed (if so I missed it), and also
for saying something that you've almost definitely covered but......

Check to see if there's any autoloading of modules, or anything, going on as a result of the
mount/fdisk?

Also (instead of the mount) does a 'dd' work?  E.g. dd if=/dev/sda of=/dev/null bs=512
count=1?

That's going to be faster & probably less intrusive.
