300 Gb external HD, Seagate ultra ATA/100, 7200 RPM, 8MB cache, in a ADS USB2 case, both new. HD partitioned approximately 35GB x 1 volume/65GB x 4 volumes. Computer is Dell Inspiron 6000, 2.13 GHz, 1 GB RAM, XP MCE sp2, both HDs NTSF.
Issues: In moving 7 GB (downloaded movie) from internal HD to external HD, external shut down after almost completing transfer at about 8x speed (so about 15 minutes to move 7GB or 17 Mb/s). This was 3rd movie moved in succession. External HD felt warm, not hot, warm. Fan is apparently working fine, I can hear it; however, I have not yet figured out how to monitor it, either temp or fan speed, as I can/do for internal HD and CPU. etc. using Speedfan program.
I'm assuming heat is the problem, that the ADS case/components are getting hot and shutting the thing down. ADS specs say it has a transfer rate up to 480 Mb/sec, I was only moving about 17 Mb/s, so way below (~1/18th) max transfer rate, if I did the math right. BTW, the external HD when doing nothing except running the fan feels warm. So, as I see it, the options are cool down the external HD or slow it down. I would prefer the former.
Question: is the external HD cooling properly? How do I determine that? How do I improve the cooling? ADS case has very small (tiny) openings for air flow and space inside is adequate but tight. But, this is what it was designed for. Can I alter the case somehow? Or is this just a fairly big HD (designed to have a lot of room for airflow) inside of a small, not very well ventilated/cooled space, and is that just how it's going to be with this setup?
Related question: Can I monitor external HD temp and or fan speed? I assume it has sensor(s). Can I / How do I access that info?
Thanks for your prompt response.
