I doubt it. disks all dissipate around 10W (+-50%) when active.
that stretches a bit lower for laptop disks, and a bit higher for
FC, high-rpm and/or high-platter-count disks.
unfortunately, seagate has gutted maxtor's website, so it seems
almost impossible to get a simple spec sheet for maxline drives.
I did find a japanese sheet that simply lists 9.97W (probably idle)
which is entirely typical for such a disk.
but I think the point is that putting any disk in a poorly
ventilated enclosure is asking for trouble. it's not really clear
what google's paper implies about this, since they basically
say that new, too-cold disks are at risk, and old too-hot ones.
