Windows 7: USB External Hard Drive keeps disconnecting.

that seems odd to me that it would only draw 2 mA

What bothers me is that it worked for almost a month and a half in the same configuration. It can't become power-hungry suddenly.

This guy has the same thing... from 3:58

Right! :) So happy to inform you that I've cracked the little devil! YES! It was the electric lengthener! I guess it was kinda sensitive or something, causing a voltage fluctuation. :). I was charging my hair cutting machine, when my USB mouse started doing the same thing... Nailed it! So happy!

Thanks to everyone that replied :). So to others that come across problems: check your gear!

So you solved it by changing your lengthener or connecting to other electrical outlet? Because I have the same problem and it's especially annoying when listening music from external HDD. Maybe I should connect power adapter of HDD somewhere else.

I had that happen with a 1TB WD drive except it kept connecting/disconnecting all the time then found out I have a power outage in the area, and suddenly my drive became a raw drive, lost everything, now it is an internal drive!

win7 home basic 64bit

so u guys sayin' this happens bcoz of power outage like a black-out or low voltage ??
Mine have been acting like this for the past one month or so .

I have a 1TB seagate external drive . For two years everything worked fine until now it automatically disconnects while copying data and re-connects . It even asks me to format the external drive , but i cancel that option ... and then i MANUALLY disconnect & reconnect the device to make it work again ;(
... So is there anything i can do to prevent it ? Mine connects directly to the usb port .

So suppose there is low voltage in my area , and at that time if i DO NOT charge my PC while the external drive is plugged in , like running my PC on battery , then will this "disconnect reconnect" thingy occur ??
Im extremely worried of losing all my data , so planning to buy another one to copy all the stuffs there but until that happens, my current one must survive . Please help me out guys
