Hello i own several portable HDD, these are 2'5 HDD drive with 1TB memory.
I own the classic WD usb2 but also two Verbatim, these one
http://www.verbatim-europe.co.uk/en...rtable-hard-drive-1tb_5276_0_28934__1534.html
These are usb2 or eSata, you have 3 ways to plug these : 1xusb2, 1xpoweredesata or Esata+SpecialUSbPowercable (that's because not all eSata plugs are powered)
I ran test with my A500 and my A700, the WD drives never had problems, but those special vertabim ones aren't working on A700 but are working on A500
Now i ran more tests, i discovered that A700 accept these with the help of the second usb2 cable (and of course another device) so clearly this is a power issue, because these drives aren't made to be used with the two USB2 cables
However, I was also a early owner of the A500 and first firmware didn't accept these drive too, so maybe ...
The A510 powered and worked with whatever I tried as far as USB portable drives. The A700 may require more power for the display, so you might be on a threshold for some slightly higher drives.

Yeah ? still the same speech since early a500, ppl like you claiming, it will accept anything, but it is absolutly not.
I admit the a700 accept on the first firmware, cameras, and ntfs, but i guess this was an issue back then with honeycomb, not usb.
But it refuses my two joypads, as A500 always did too, and i own two very common joypads: our national FreePad, and wireless xbox360, they both refuse to turn on when plugin, strange thing, they are both working perfectly using USB/BT center app. That include sending power for the leds, only when the app is on.
Also back then it rejected numberous sdcard usb adapters, i won't test them all again with a700.
As i said back then A500 refused my verbatim too, they added whatever support later, i'm disapointed to hear that you think they'll never fix it.
Does it always require 2nd usb cable to be plugged in or power adapter plugged in to the drive?
it a tablet so if doesn't have enough power to power external devices, wouldn't it be fairly normal?

it does not, of course, as it's a portable drive (that means self powered), and it works on a500.
The extra power feature is only there for old esata plugs.
Maybe a simple picture would be clearer (and proof)
As you can see the A700 turn on the verbatim led, but that's all

The A510 is not the same. I found the A500 as bad for portable drives (only kept a few weeks) as it was for wifi reception. Not the same comparison at all. The A510 is a good tablet, but the right side getting hot started to annoy me and I returned it.

Yeah but later firmware changed it a lot (more compatibilty, cameras, ntfs, pads, mouse support added), and now as i say: actually A500 accept more devices than A510 !

This could mean, that power is not distributed to the usb port in order to save power or it means the drive itself is "A power source" for example you'd charge the A700 through the usb port.
IF this is true then it is the drive itself having such a "Feature" therefore the tablet's behavior in this manner is indeed normal.

led is lit-> power is distributed
no, a portable drive isn't a power source
tablet's behavior over old model cannot in any way be normal

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?
A workaround I was using when I really had to access a harddrive was to use a Y-USB-cable and a wall charger. The first USB plug of the Y cable went into the tablet, as this one usually has the data connection, the second one went into the wall charger. The wall charger supplies the extra current that is required by some hard disks for the spin-up phase.
Of course this is neither comfortable nor portable, but does the job...

Good ol' thread I'm trying to forget
Just wanted to say that problem sorted itself out after changing the motherboard lol (tablet was dead soon after post).
After that it didn't happend a single time. It's also possible that Android was more stable after updating from ics to jb, hard to tell.
Anyways, I got rid of the tablet. Not that is was bad or something, just time to move on...
Yeah, sorry for necro-posting, but maybe some other person with a similar problem finds the thread or so.
Also I am trying to get to 10 posts to be able to post my A701 port of CM10.2 in the dev boards, and it's hard to add some stuff with at least some value to other threads, as they all are pretty old =D

I'm just posting for brief warning/general info for you guys. When I got to work tonight I plugged in my USB OTG cable which I have been using w/ no issues on both my N7 and S3 since July and then plugged in a 64gb flash drive that I have also been using since launch. When I plugged in the flash drive, I heard a pop, the screen went blank and the phone is totally dead. A quick search showed while this isn't incredibly common, it has happened to several people. Most blamed the OTG cable, but I disceted mine and it had no broken wires and no shorts. I turned up a thread on root wikiz that basically said that it is the power management IC self destructing and there is nothing that can be done to repair it. So, just a heads up if you use OTG-- I am not sure I will use it again on this phone as it seems it is just a matter of time...

Jason

This happened to me. Verizon will warranty the phone. I wondered what actually blew up in the hardware. I am surprised it hasn't happen to more people, seeing how you really don't have any control over whether it blows up or not.

Sorry to here about your phone. I was jut about to go buy one of these cables.
This same thing happened to my phone a few weeks ago. It went totally dead out of nowhere, I was taking photos at the time.
You shouldn't have a problem getting a replacement even if you don't have insurance.
Good Luck
I have heard stories about that happening, though its not common, it is surprising that its so low considering its random and no one knows exactly what causes it
at least you don't have to factory restore before returning
Sorry guys, I just woke up. Was on graveyard shift last night. Anyhow, the cable was a generic ebay right angle otg cable, about 5" or so in length. I am 99% certain it had nothing to do with the cable though, just a hardware problem. As mentioned above I dissected the cable and it had no problems. I could still use it on my Nexus 7 with no issues. I had the cable plugged in before inserting the flash drive and it was fine until the flash drive was plugged it.
The Root Wikiz thread I mentioned said that someone had sent theirs in to be Jtag'ed thinking it was just hard bricked. The response from the people where he sent it was that they had seen a number of them with the PMIC damaged and that there was nothing that their services could do for them.
My guess is there are some marginal PMIC's out there and that when they switch the port from charge to host mode they just cant take the current and pop. The fact that I made it nearly 5 months using the same OTG cable on a regular basis kind of lends credence to this theory, but who knows. All I know is that it was totally dead, absolutely no signs of life regardless of what I tried.
FWIW I was rooted and running paranoid android, but I have found reports of this happening to bone stock phones as well as any variation of ROM. Verizon did warranty the device. Oddly, the tech told me "I have never heard of this happening" but didn't even ask me to try anything with the phone, he just said that they would ship me a new one for warranty replacement.
New device is here, I'm off to root and unlock! Good luck guys.

Wow, that sucks, but I am glad you got another S3. I have been using this one that I got from Amazon. It has a couple of usb ports and 2 card readers. I have been very happy with it. It is extremely useful when I am at family functions, and everyone has taken a lot of pictures and video. I can grab their cards and pull the pics and video onto my 64 Gig SD card on my phone. People are amazed I can do this with my phone! However, now I am a little worried about using it. I will keep this in mind, and only use it on the occasions that I really need it. Thanks for the heads up!

but i think the s3 is already wasting power and i must charging it after a day.

One day charge is normal if using phone. If gonna use OTG you are overusing and can expect 1/2 day. Buy good cable if want data.
I had something similar happen except, my usb sent a static spark from my oc to my phone. Didn't fry it completely, but messed up something that would no longer dock to pc, dock to car our go into deep sleep.
Wonder if the two issues are related.
Be sure to discharge any static in you usb called before plugging them into your phone.

Discharging is what the battery always does when not plugged into A/C power and turned on, and even sometimes when it is plugged into A/C power (when you get in the top 10% of full it starts going through discharge/charge cycles to keep it within the top 10% of power but never totally full. This prevents overcharging and explosions)
That said:
A sudden reduction in the runtime for the battery under the same average load is almost always the battery going bad.
If you mean the battery doesn't last as long because you now use OTG - those things you plug into the phone need to get their power somewhere. The phone battery is it.
So now you are powering the phone + whatever other things you attach to it. Some of them can drain a lot more power then you might think. You just never noticed much (if at all before) because your total reserves weren't such a tiny amount.
If you stop using OTG devices and your battery capacity bounces right back up to where it was before, then you can reasonably infer the extra gadgets are the culprit.
(if you stop OTG stuff for a few days and the battery still sucks when before it didn't, probably need to buy a new battery because yours is most likely shot.)
Assuming it seems to work fine...
So two choices, right? No accessories and lots of battery life, or lots of accessories and no power to run them with.
well...not really:
It's probably not always possible - but how often do you use OTG near A/C power?
Whenever you are near somewhere you can plug in, the first thing you should plug into your OTG cable (besides the phone) is a USB hub with a power cord.
...and really, if you want to use those power hungry USB hard drives and things like that, then you really can't without taking the stress off of the phone of supplying that power - that hard drive just half spins up like a car that cranks but won't start.
Every crank in that car wears the battery down and beats up the starter when it doesn't fire up the engine. Just like every spin up but not quite read of the hard drive puts incredible load on the S3 to try to throw enough current at it fast enough to keep it happy. Just beating it up for nothing.
Which brought me to what I wanted to bring up for some consideration:
Think about trying to use a powered hub whenever you can as the first thing off the OTG cable, should take an immense amount of stress off of the S3 in making it all work.
Bet at the least you reduce the risk of popping since the power spikes will be much less - that powered hub is a pretty solid buffer for that kind of stuff when you are constantly popping flash drives in and out.
I remember way back when for the Nook Color when some really sharp people made OTG happen out of the thin air - no way Barnes & Noble had that on even a remote list of possibilities when they were ready to throw the device to the masses and see what happened.
If you wanted to use more then the smallest of thumb drives you needed a powered hub. The device wasn't designed for it, and simply wasn't able to squeeze more then a paltry amount of power out in reverse. (but it was just enough to talk to a powered hub...)
Anywhere that you can plug in your powered buffer should contribute to avoiding the problem the OP posted about. The thought experiment (hopefully) growing from this post? How much truth does this theory exhibit?
Edit: Totally missed this post:

Here you say you made an OTG cable, the first post I quoted you in you said you bought one. If you made it, i'd say that is your problem.
The quality of the cable you use absolutely matters. Higher quality parts = higher quality results.
I have a bunch of micro USB cables (as i'm sure many of you do also - ) ... and from some of them I get an absolute night/day result in charging.
Some cables (mostly the ones from the dollar store or older cables) just plain suck. They can't bring enough power from the same A/C adapter as my OEM HTC/Samsung cables. (I have some motorolla OEM cables from around the time of the droid X launch - they are closer to the dollar store cables in quality - haven't tried recent motorolla OEm cables, hopefully they got better or I got a bad batch over a six month period)
Using the low quality cables I can absolutely lose power plugged in just being a wifi hotspot with the screen on, until it eventually goes critical and dies. (this I tend to notice when my pc banished to the corner of nowhere loses all network connectivity) - whereas with the HTC/Samsung cables from within the last two years keep me near full with that being the only difference.
I'd rather have a few good cables then a bag full of POS dollar store ones. That little bit better material, little bit tighter QC adds up to a big difference in the final outcome.
This same thing happened to me when I plugged the same type of cheap right elbow OTG cable from ebay into my brand new S3 (2 days old with about one hour of usage). The cable worked fine with USB drives, a mouse, or a keyboard used alone on the S3. The cable was plugged into a USB 4 port hub with multi-card reader. The screen was off when I plugged it in so it appeared to just be off. Any attempts to power it on were fruitless. I smelt the phone right afterward and there wasn't any burnt smell. Plugging in the phone resulted in it getting pretty warm but not to an extreme yet the battery remained cool. It appears to have burnt something between the battery and lines but leaving the components intact thus causing the excess of heat. BTW the hub/reader is fine. I won't be using that again on my new one but I will be attempting to use a different hub that has been working fine on my wife's RAZR MAXX HD. Just hope this is a very isolated incident and not a bad batch from the retailer.
Edit: The S3 is a blue 16G Verizon model. The S3 was on stock ROM when this happened (not like that would prevent death from inferior circuit protection components).
Were you using a powered hub, or passive hub?
Anyone tried a DAC off the OTG cable?

Don't do it. I've fried 2 GS3s with a UCA-220 DAC over otg.
First time with a regular OTG cable, the second time with a OTG/phone charging cable, the power came unplugged and zap. I'm lucky Verizon has replaced the phone two times.
I think the best solution is to completely isolate the DAC power from the phone power. A circuit to charge the phone with the otg/charge cable and a separate circuit to power the DAC.

Wouldn't use of a powered usb hub remove any power issues? I purchased a OTG cable today.. I had planned to connect it to a powered hub, and run the DAC off that?
My Windows 8.1 PC would not recognize my Shield Tab with the supplied USB cable. Charges fine, though. However, the Shield Tab is recognized with either cable from my Samsung Note 2 or LG G Pad 8.3.
Anyone else experience this? Looking for feedback before contacting Nvidia.
My tablet is not recognised on Linux either, whereas my nexus 7 2013 was. It did have Franco kernel installed, which might make it mount the file system better than stock.
I am able to see mine in windows and my linux vm

Actually, I stand corrected. My tablet is visible in LInux in MTP and PTP mode.
Have you tried the usual tricks about swapping USB sockets, and checking your Connected Hardware in Windows.
I also have USB Debugging on, if that makes a difference.
The Shield cable is the same as any other Micro USB cable, so if you have another one lying around for another phone, give it a go first before going to the hassle of contacting Nvidia.

Actually, I stand corrected. My tablet is visible in LInux in MTP and PTP mode.
Have you tried the usual tricks about swapping USB sockets, and checking your Connected Hardware in Windows.

Thanks. It's definitely a bad cable. I've tried USB cables from 3 other devices and the Shield tab is recognized by my PC with each of them.
I have a SCH-I915 (Verizon) which is not recognized by any machine that it gets plugged into. There's no unknown device, no beep of a usb connection, it does beep like a charger has been connected (and gets the red x on the battery icon, indicating the amperage is insufficient), but the PC doesn't recognize there's an interactive device on the other end. I have spent 3 days combing the forums. I can assure everyone, it is NOT a driver issue. For one thing, the same laptop that flashed the wrong firmware and unlocked the bootloader is among those who can't see it. It also isn't visible to the best buy samsung rep or he'd have flashed it for me. I've also used anycut to manually select mass storage or samsung kies. Neither work. After reading many, many MANY posts on devices not being recognized, it seemed to me the ultimate fix for most of the people with these symptoms was a new cable. I just bought a cable and it's the same. The original does me no good, neither does the new one (which is an insignia from best buy). The maddening thng is, it was working FINE (apart from being unusable...but it was able to be connected to any way you like) just a few days ago. It was the factory reset from within the 4.1.2 OS that seems to have changed something. My idea (which may be entirely off base, since I don't actually know the USB protocols is, the tablet gets plugged in and either is supposed to say "I'm here" or the PC asks "who are you?" After that would be steps on establishing what device it is, etc... I think this initial handshake is what's broken. The PC thinks it's got a usb fan or whatever, the tablet thinks it's connected to a crappy charger.
So I've got a couple questions
1) Do they make charging cables which are distinct from the data transfer cables?
2) Has anyone used one of these insignia cables? Was it fine for you?
3) Is there any other nuclear option I can deploy myself? I don't have much faith in those best buy guys. (On a side note, I was allowed to use the guy's laptop to try and get it to work and if I had had a thumb drive, I'd have all the cool imaging software they have...but it was not to be.)
Does it shows up when connected in recovery or download mode?

No it doesn't
No matter the computer I'm attaching to, nor whether it's in download, recovery, or fully up, the connection appears to only be seen by one side.
I recently purchased this tablet from Walmart. It was appealing because it was cheap and looked to have everything I needed in a cheap tablet. I have not however been able to get my laptop to recognize the tablet when plugging it into the computer. It has two ports, a full size USB and micro USB, on it but neither work with the laptop.
The full size USB does nothing when plugged in. It does not recognize it at all. The micro USB does recognize but says the device isn't recognized and it will not give me options to update drivers and comes up short when troubleshooting. With RCA's outstanding customer service I have gotten nothing but silence. I really like the tablet but I am a bit frustrated with the inability to load my files on it.
Does anyone have any suggestions?
Thanks,

You didn't say what Windoze you are using. The first thing I normally try is to install PDANET. I don't even know what PDANET is for, but it has a LOT of drivers, and normally fixes issues I have connecting strange phones and tablets. Just go here http://pdanet.co/ and use the download for Windoze button. This link also seems like my solution: http://joyofandroid.com/how-to-install-usb-driver-for-android
Good luck. Android access from windows is more or less a crap shoot, but it can usually be made to work.
