[Q] G Tablet Reboot with External HDD

Hello,
I thought I'd try and see if anyone else is having a similar issue.
I recently picked up a western digital 500GB passport external hard drive.
I formatted the hard drive to fat32 and double checked there are no extra partitions on the drive.
I'm mostly running CyanogenMod 7 with stock kernal lately and I've found when I hook up the hard drive, the tablet stutters a bit and then reboots.
On bootup it gets to the unlock screen, and when it starts scanning the sd card, the scanning message starts to cycle quickly and the tablet reboots again.
I restored to a backup of vegan5.1 to test on it. Same thing, on insert the tablet starts to hang and reboots.
On vegan though, on the next reboot, it would start normally, but for some reason its not mounting the drive. I search under usbdrive and don't see the folder and file i put on it for testing.
Anyone else having issues like this? Could the problem be its a 2.5" drive and no external power? I know when its hooked up, the light comes on and I can feel the drive spin up and vibrating, so not sure whats going on.
Thanks for the help

That (not enough power) sounds exactly like what's happening, I.e., the drive is drawing so much current from USB that it's either causing voltage to the gtab internals to drop to the point that it resets.

If this is the case, does anyone know what 2.5" external hdd's will work with the power requirements? (Someone who has one that does work?)

You could always get a powered USB hub, provided that isn't too inconvenient to carry around.'
Edit - Most 2.5" external drives that didn't require external bricks that I have seen have a 2 prong USB adapter. One for data and power and the other for more power only, since each port maxes out at around 500mW I think. Obviously we have only one port, so a powered hub or a jury rig.

I think others have gotten some drives to work, but not sure if they were 500gb. Also, even w a specific model, if the current draw or voltage are just 'on the edge's of working/not working, you may or may not get lucky.
BTW, have you tried w a thicker/heavier USB cable? Thinner/smaller gauge wire has more resistance, so voltage drop would be less over a shorter, heavier gauge cable than over a longer, smaller gauge cable. I have actually had drives not work, then switched to a thicker USB cable then it worked.
Jim

On a similar note, just yesterday I purchased an external USB DVD+/-RW for use with my netbook and tablet and it would not work without a powered hub between the tab and the DVD.

My 160GB ipod classic works fine, but my 1TB external drive that has an external power source doesn't work with any of the ROMs.

Does anybody know the maximum current supplied by the GTab's USB host port?
My 2.5" 500 GB External came with only a short (single) usb A to usb mini cable.
And it gets powered up fine from every laptop/netbook I have tried. They have always displayed 500 mA max current for each port.(when I look in Windows Device Manager, USB Root Hub).
Can the G-Tab supply up to 500 mA from it's USB host port??
I want to make sure it will work on a GTab before I buy it.

confirmed working external HD on g tablet
Using tnt lite 4.2.4, i personally have a 500gb formatted in fat32 working
model 500gb free agen go flex.
I've tried the latest WD passport SE, spun up and didnt detect in astro, ES file explore or stock file viewer
i have over 100gigs on this drive, about 80 of music and some Tosh.0 and everything pops up instantly and runs all the music fine out of MORTY music player... plays perfectly. Must have for your powerhouse. Hope this answers all the unanswered questions about external HD's on g tablet.
I have not tried stock rom or any other roms.
If you are looking for different external hard drives... make sure they are LOW POWER and NOT 3.0. 3.0 seems to require a driver to work. So its kinda hard to walk into a store and buy 2.0 only devices now.
Goodluck all.... i was using a patriot xt 64gb rage flash drive before this but 130 bucks is outrageous vs 75 i paid for the 500gb seagate.

[Q] USB Adapter to work with ext hd

Hi,
I was curious if anyone got an ext hd to work with the usb adapter?
Everytime i plug it in, it tells me a "high powered ext hd" is connected but unable to read..i know it was made for usb sticks and keyboards etc but has anyone gotten ext hd to work?
Thanks!
sent from the iPhone's pimp, dont make me have to slap a B

I found my 1Tb Hitachi Touro was detected to start with but the power was insufficient to leave it on. It was not working after a few seconds of being plugged in. Memory sticks are no problem but the HDD sucked more power than the 10.1 wants to give...
Shame that an awesome tablet that runs rings around just about everything else falls short of my Acer Icona A501 for this...:crying:

I used a 1A externa battery to power an HDD and it worked just fine on the Note. The HDD was NTFS, but I used USB Mass Storage Watcher and mounted the partitions.
To get it ti power on you need a split USB/ power cable.

Yeah, my Acer A700 has this ability but unfortunately the Samsung Note doesn't have the power.
The fix is to buy a self-powered USB hub... Or use high capacity thumb drives.

Or use a hard drive with provisions for external power.

I plugged my ext powered hd but still no luck. Oh wells! Or maybe split line usb and ac like someone recommended
Thanks guys!

Split USB is your best bet. No hub needed, just an external source of power like a portable battery.

Yeah, but it bites my kickass up-to-date sammy tablet is put in its place by my 18 month old Acer Iconia A501 that supports the 1Tb 2.5" HDD with no problem.
I think this bites a bit. Makes life hard If I need more storage than most thumb drives supply...
No how am I supposed to take a veritable video store with me to watch....

If you could run an external hd via USB it would drain the battery pretty quickly.

Nope, get at least 6 hours of watching videos from the 1Tb hdd on the acer Iconia A501... The battery is not as beefy as the SGnote 10.1's either...
Just an oversite by samsung...
Just a pain now having to carry 2 tablets around...

It won't because the Note will not provide power to the HDD, you have to use external power.

Can GS6 Handle 1 TB External HDD?

I have used external hard drive before with my note 3 but it's only 150GB. Now with S6 having no expandable SD card, I'm thinking I'd keep an external hard drive handy. I know it supports USB OTG on the get go but can I it run 1 TB HDD without extra power source? I think this is better than buying a 64 GB model with the same price of 32 GB model and 1TB HDD.
or do you think I should go with the 64 GB model?

Did you have 1TB of storage on your previous phone with SD? If not, why do you need the hassle now? Why not get a MicroSD adapter that is a fewe $ and still use your MicroSD?
To naswer your wuestion - it will not handle a device with that much power draw.

Because my macbook storage is almost full so I find the need of using an external HDD. Do you have any idea what maximum storage GS6 can handle via USB OTG?

Hard to say, but I would first start with upgrading your Macbooks drive instead of looking at solutions like connecting a 1TB drive to a phone.
An extreme solution would be to get get proper cables and use a powerbank to power the drive and have it working on the phone, still.

It's not the size drive that's the issue, its the type of drive you connect. A flash drive is one thing, bit don't think about hooking up a 2.5" mechanical external hard drive. Even if it worked, your battery would die in no time.
Sent from my "bigger is smaller" LG G3

Let me break it down.
Note 3 USB OTG output current: 900mA
Note 2 USB OTG output current: 500mA
Note 4 USB OTG output current: 600mA
S4 USB OTG output current: 500mA
HTC m7 USB OTG output current: 300mA
HTC m8 USB OTG output current: 500mA
So, maybe, maybe not. Note 3 can run every drive I've tried except the power hungry 4TB Seagate Backup Plus Fast.
If you want to measure your drive and find out the current draw, just buy the inexpensive CHARGER Doctor.
Also, the S6 will probably have 600mA output, so it most likely can handle some drives, but you'll need to measure to be sure. I'll be testing an S6 soon to verify output current.

External hard drive support

Hey,
I would like to connect an external 2.5" hard drive to my Samsung Galaxy Note 10.1. I have the original samsung adapter kit, but I read that it won't be possible because the tablet has not enough power output for an external hard drive. I don't want to risk breaking my hard drive or tablet so that's why I ask here first. Would it work if I connect one USB plug of the y-cable to the tablet and the other one into a powerbank?
How did you solve this problem?
Thanks in advance

Some drives have ability to use their own power supply. Look for one that does.

OTG Volatges or Amps for HDD

hi everyone
I was wondering if anyone knows how to increase the voltages or amps for OTG to make power HDD successfully
I have 1TB and 2TB HDD
both are working with my Note 3 N9005 and Note Edge N915S without extra power
but for my Note Pro P905 they both need external power
the Note Pro does not provide enough power for them
so
I want to know if there are files that need to be edited to increase the power supplied for the HDD through OTG cable or do I need a custom kernel
thanks

That's odd. It reads my three 2TB WD Elements drives without issue... Even two of them at the same time over a hub works without issue.

Over a hub with external power right?
It works with external power
But try connecting one of them directly without power
It will not work
The hard drives works with My note 3 and note edge without the need for external power

No, just a regular USB hub without external power. This one: http://www.saturn.de/mcs/product/_ISY-IHU-1000-4-Port-Hub,48352,278643.html?langId=-3
But I do believe it depends on the drive itself. I have an Iomega 500Gb drive that won't load without external power, while my 2TB Western Digitals do.

Which variant of the note pro do you have? Is it the P905?
If it is p905, then which rom are you using?
What cable do you use to connect the hub to the tab?
And which models are your 2tb hard drives?
Because i have wd passport 1tb and elements 2tb
Both are not working with tab but working with the phones

P905, P905XXUANC3/P905DBTANC3, pure stock. (Yes, still on KitKat.)
USB Cable is the official Samsung ET-R205UBEG OTG cable.
The two drives are both WD Elements USB 3.0 2TB. Both formatted as EXFAT.
I had a WD Passport once, but it had problems with my old TF700T due to the backup partition and the autorun.

Buy a portable charger ��
Gonna try to get it back to kitkat and test it
Or see the difference in kitkat kernel vs lollipop kernel
update:
got back to KitKat (P905XXUANC3)
and it does not work without power also and I lost the LTE connection :crying:
flash drives are working fine
only problem is with the 1 tb and 2 tb hard drive
(I don't have a smaller hard drives to test for now)
going back to lollipop and gonna try to find a solution

Bah, I'd really hoped that would work...
I have a portable powerpack, a 15600mAh Asolar Xstorm. It's just not very convenient to have to juggle a 12" tablet, portable harddrive hanging from an OTG cable, as well as a powerpack the size of a 6" phone, alongside my already 5.7" phone, whilst switching trains and standing in crowded carriages. :laugh:

The only drive I have with me right now is formatted in NTFS. (Because the piece of crap Windows XP Dell PC I have to use here is too old to recognize EXFAT, and FAT32 doesn't support 5GB Photoshop files.) All it does is give an Unsupported file system error. (Which makes sense, as I haven't rooted)
Edit: Okay, borrowing a drive from a friend to check, this is a 1TB WD Elements in EXFAT...
Edit 2: That somehow won't load. Device just says it's blank or unsupported. I'm confused, why isn't this one working?

Can you try with your hard drives and make a video?

I can't make a test because my portable drives are all formatted ext 4 or ntfs, but I'd check the portabla case itself: many portable cases show strange incompatibilities: a different chipset and/or usb chip can be the culprit. Unfortunately the only way to check this is to open the case. WD may have changed something in the hardware or the firmware, if any, over the time and this could explain why some drives work and some not.
My suggestion is to check the compatibility prior to buy a portable drive.

It is not the hard disk itself
the problem is with the note pro
i have many 2tb & 1tb hard drives
all of them work well with my phones
but none work with the note pro

Not the hard disk but its case. It is the combination of case and taget device that makes the difference. Some of my devices do not work if attached to my modem but do work attached to to my laptop or desktop pc, others do the opposite. The only case I found to be compatible with all my devices is a thermaltake one, that I bought because it was listed in the compatibility list of my desktop's motherboard.

my hdd also requires a battery pack to function over otg. its a 500gb usb3 toshiba. i went round and round with this for months and could never solve the problem. mine is the verizon unit, and i think that has something to do with it as any other non-verizon note pro sees the hdd with no problem, no power pack needed. (even works fine with tab pro wifi model and galaxy s4, s5, and s6). didn't matter how i formatted the drive, it still wouldn't see it without the power pack.
quite frustrating.
-lq

This will depend mainly from the Hdd that's inside the case.
I personally assemble my portable hdd's buyn a case and a low power hdd (Wd green or so on). It's very simple and you know what you have. Doing this way I never had power problems even with usb2 sokets.
Keep in mind that an usb3 Soket is rated at up to 1 Amp, while an USB2 socket is rated at max 0.5 Amp. I don't believe that any portable 2.5" HD will absorb all that power , but I would not be surprised if on a tablet the available current was much less, to limit the maximum discharge rate of the battery with consequent risks of dangerous overheatings.
In any case I guess that on the Market there are cheap usb gadgets able to measure the absorbed current from an USB socket. Ebay or Aliexpress can be good sources for such gadgets.

I've posted this problem on other thread too but the question is related to this thread too, hence I'll ask.
My smartphone (an Asus device) is able to power up HDD (2tb Seagate Slim BUP) by itself and can read and write files too(I use Total Commander app along with a 3rd party plugin to read and write to NTFS drive.) Problem is my smartphone's battery drops 1% every 1.5 mins when HDD is connected to it directly.
So I want external HDD to draw power from external supply ONLY (from powerbank or 2A charger) and not smartphone. Ofcourse phone will use some power but primarily HDD should use external supply power.
Is it possible to do this ? If yes, which hub or cable should I use ?
I had bought a OTG Y cable but on connecting micro usb end of cable to smartphone, phone started charging itself and HDD turned off. I tried both 5V 2A charger and powerbank with same output.
Is there such thing as a hub or OTG Y cable won't use external power if smartphone is capable supplying required power? Or the cable was faulty? I'm new to all this so could you tell what went wrong ?
