Yeah, A700 gets confused and thinks the drive is a power source.
Do you have any other problem using the drive with any other devices or pc?

again, it works on A500, and at least 5 other players, pc or mac in both modes, and OF COURSE without the power cable, that's why i bought them.

Try plugging the charger to the tablet and then connect the drive see if that helps.
In an example, sometimes in the scenario where a usb hub doesn't get enough current the devices plugged on the hub won't work.
So, maybe A700 can't output enough current to the usb for the particular usb device that you're trying to connect.

If that doesn't work you can still call them for support or return it under warranty.

It's also possible that the harddrive needs to much current. The USB 2.0 spec specifies a maximum of 500 mA, but some harddrives use more, especially at spinup. That's different between brands and versions.

Hi every1! I have a similar issue on my A510 using Samsung Spinpoint M8 1TB external hard drive. It works, but not for long What I'm experiencing really starts to annoy me. When, for example, I'm transferring my videos from a tablet, hard drive just "disconnects". A second after I get a new notification message that USB device has been plugged in, like I myself disconnected the cable and connected it again. That wouldn't be a big problem if my whole ntfs file system isn't f....d up and previous data lost! After that I need at least 15 minutes to correct the problem in my Windows environment, not saying I have a couple of gigabytes more free space after fixing that (lost data). Hard drive is almost new, doesn't behave like that when connected to a laptop or a desktop, so according to what all of you are saying, my tablet doesn't distribute (constant) 500mA, or hard drive doesn't meet USB 2.0 specification and requires more than 500mA, right? I first thought it's about Android's ntfs compatibility, but now after I've read this thread, I'm with you. However, my ntfs formated sd card and ntfs usb stick don't behave like that, so it's not about ntfs afterall. Hard drive indeed comes with 2 usb connectors merged into a microusb, but that's not helpful since I have a single usb port on my tablet. Also, I can't have my hard drive connected while recharging in order to give my tablet more "juice". Should I maybe lock the screen to conserve the power and have a more stable current flow when copying data to my hard drive? I might try just that. What do you guys think?
