Did I reduce the longevity of my Hard Drive by this silly mistake of mine?

Yesterday, I was multitasking (not at the computer, but at the home) when I plugged my 320 GB Seagate Freeagent Go external HDD into a USB port of a USB hub. The motor didn't start due to lack of power and I immediately, completely forgot about that I had plugged it in, and went to do some other household work.

When I returned after 4-5 hours, I found the HDD plugged in, and very hot to touch (I guess the external case was around 55 degrees Celsius = 131 F.) Not sure about the internal temps, as SpeedFan/HW Monitor didn't show it.

Still plugged in, when I put the HDD against my ear, the motor was still trying to spin up the HDD, but failing in the middle, and repeating the process again and again at an interval of 2-3 seconds.


I got upset. I unplugged it, and let the HDD cool down. When I plugged it to a USB port of the mainboard, it worked fine, though.


I'm still upset for this silly mistake of mine. Do you think I reduced the longevity of the HDD motor because it was trying to spin it up for 5 hours? And also because it was hot?

Please note that the HDD was inside a pouch, which led to poor cooling.


Thank you, everyone.

That should not damage anything. It's just running an electric motor that has a VERY LONG MTBF.

Dropping the hard disk would have been bad.

Be grateful. No problems.
