Do you have an idea what a normal operating temperature for 2.5" drives might be?
On my usually-on-but-often-idle laptop (running FC2 for relevance to this list!),
/usr/sbin/smartctl -A /dev/hda | grep Temperature
reports 38 degrees C at the moment. This doesn't seem very hot as electronics go,
but I don't know about disk drives.
That temperature can rise a good deal if the disk is very active,
or especially if the laptop is in a confined space; its lifetime peak is 53 C,
which does seem uncomfortably warm, but it spends almost no time at such high temps.
Mine is a Toshiba drive, though not a Travelstar -- it's a MK6026GAX.
