American Hard Drive Instability in China

From the USA, I have brought several external firewire hard drives that I connect to my Macbook Pro to edit in Final Cut Pro in China. On all the hard drives power bricks the input is rated 100-240V, yet whenever I turn on Final Cut Pro the program constantly crashes. I noticed that my hard drives vibrate because of the 110/220 voltage difference, so my theory is that the drives don't work well with 220V electricity despite the specs written on the power brick. So today I bought a large transformer, Yue Ying brand, rated for 2000 watts. The input is 220V and output is 110V. I've connected a brand new American APC 10 outlet Back-UPS to it, and my hard drives to the battery backup plugs on the UPS. Final Cut Pro is still unstable and crashing. I'm not sure what to do at this point. The salesman connected the transformer to a digital meter and rated 110V. I'm wondering whether the hard drive should run at 120V, or possibly the 50/60Hz cycle difference is causing the issue. I do not have this issue at all in the USA, only in China. Any advice would be most appreciated!

Thanks,

China is full of local hard drives- get a local external and see what happens. It seems a little unlikely the voltage is actually affecting FCP though.

I think the hard drives in china are supposed to spin the other way... or wait, maybe it's south of the equator that they do that.

The power brick's output is DC, not AC, so the AC input voltage is irrelevant if the brick is rated for both. The smoothing filter is probably not the best in the world, but still DC, so the 50/60 Hz doesn't matter.

You have other problems IMO, perhaps the disk access speeds causing FCP to crash?
 
Since you're running off a good UPS, your power isn't the problem.

Try deleting your FCP preference files and see if that helps. I had a recent rash of crashes and deleting prefs did the trick.

I've had the same issue and deleted preferences, it help. Also
what kind of firewires are you using? The firewire bus could be conflicting with something else.:Drogar-Smoke(DBG):
