FreeAgent heating issues
(It's my first post here, you are doing a great job!) I found your forum by searching how to open my brand new FreeAgent Essential and I saw you having many problems. I wanted to open it to fit in a fan (you can read my story
here)
I think the main cause of your problems is overheating. As I describe in the link above, my brand new unit's temperature can easily rise to 58 °C (136.5 °F). After fitting a fan (even in a quick and dirty way) the temperature fell to 39 °C (102 °F) and did not exceed it even after 30 minutes of intense file copying.
The FreeAgent's cooling relies on passive airflow from the base grid (which seems adequate) to a very small exhaust on the top. This design, together with the very small dimensions of the box, does not ensure enough airflow to cool the disk.
After my experiences, I think the following advisory is mandatory:
1. Do not trust external hard drives not having a fan if they are designed to work 27/7
2. Do not ever buy a USB drive that does not have a fan or its enclosure does not have room for adequate intake and exhaust of airflow
3. Avoid as much as possible spinning down the drive, unless it doesn't have a fan (in which case it is designed to shut down after 5-10 minutes of inactivity
It's mainly heat that kills hard drives. Unfortunately not all of them are supported by SMART monitoring tools, so the average user does not know if the temperature he feels is OK or how hot the drive actually is. In the case of FreeAgents (which are supported) I strongly advise you to experiment a bit with a SMART monitoring tool (like
Hard Disk Sentinel, which provides on their site very good
information about SMART) and watch your temparature rise to 58 °C (136.5 °F) as did my brand new one...
Finally, I believe that everybody using a computer:
1. Should urge Microsoft to develop free AND built-in AND installed by default SMART monitoring tools for its operatings systems. Most modern motherboards natively support SMART and probably you have noticed the reported temperatures when setting up your BIOS. Unfortunately, in Windows you need special tools to access the information, which has the disastrous implication to dumb down the users: a) they don't get the habit of monitoring their hard disks' health; b) they think of the hard disk as a black box, when instead it is a VERY sophisticated piece of technology INCLUDING predictive failure early warnings; c) when their disk fails, they blame the manufacturer of the disk, instead of the operating system which did not warn them.
2. We should urge Seagate and Maxtor to either design better cases, or to include a fan at the expense of price and/or noise. Don't they realize that heat destroys their reputation and their sales? Unfortunately users prefer to buy the fanciest or the cheapest drives and they do not sit back to think about the security of their data. It's true that including a 10 cents fan might increase the final retail price by $10 and make the product less competitive, but for god's sake, confidence on the storage device is #1 priority on my book (and not performance, geek factor or cool looks).
Long post, but I hope useful.
