USB/HDD capacity on Head unit - Android Head-Units

Hi,
Can someone explain to me why many Android head units will have a 64GB limit on a USB stick but far higher on HDD. Below is from a Joying unit specs.
USB/SD slot maximum compatibilitySupports USB flash drive and Micro SD card with up to 64GB of storageHDDSupport external hard drive with up to 500GB storage

I don't think those are generally accurate. I'm using a 128GB USB flash drive with no problems. I've read some use an external 1TB SSD.
I think biggest issues are format (FAT32/NTFS/etc) and power requirements of what you plug into the USB connectors. For drives with a higher power requirement, you'll need to power the drive some other way. There may be other considerations.
I can't say what will and won't work, though. If the vendor gives you those specs, you can't complain to them that a larger drive than specified doesn't work. You'll just have to try what you have to see if it works.

External HDs

Can Iconias USB supply enough power to run external 2,5" HD (5V/0.55A). Some cases seem to have 2-headed USB cord for extra juice, and some make do with only one... And requiring 2 makes them pretty useless for iconia. Any experiences?

I use an WD external 250 gb hard disk on my iconia with no problems and it has 1 usb
Using a Freecom 320gb, had to format/patition to FAT32 since it won't read NTFS.
Basically all the single head USB-cord drives work, and afaik they have to be FAT32 (havent looked into reading NTFS).
I'm utilizing an app called Drive Mount to use my external 320GB NTFS-formatted hard drive.
I have a dual-head cable, but running single is no problem thus far.
Works like a charm.
It depends on the external drive; if the drive needs the 2nd port for power ... well ...get a better external drive ;P. I've used a verbatim Usb3 drive as wel as a number of external cases with old laptop drives (my new fave is a vantec USB3 case w/ an OCZ SSD in it.

stickmount + usb flash drive

I bought a 32gb SanDisk Cruzer Fit to store my music library on, and it worked initially with USBOTG and stickmount. However, it no longer works with Nexus 7, all other memory sticks are fine, and the SanDisk works on my PC, but not the Nexus 7. Anyway, I plugged it into a USB hub and it works again, but only through the USB hub. Anyone else noticed this kind of behavior? I'm guessing it's related to power draw, as the hub is mains powered, but I'm surprised it can't cope with a flash drive. I'm now wondering whether to buy another device, or whether the same thing will happen.
I had the something similar and a reboot fixed the issue for me. I tried plugging in my 250GB WD Passport but I guess there wasn't enough power for the external drive because it kinda just sat and clicked. I then tried plugging in my 16GB thumb drive that I know worked the day before but now matter what I did, I could not get it to mount through StickMount. I rebooted the Nexus7 and I was then able to use my thumb drive again. Not exactly the same but try a reboot if you haven't already.
I also have that problem with my Buffalo USB hard drive, where it sits and clicks, it's OK via the hub, but not direct. A reboot doesn't make any difference. I'm wondering if it's my USBOTG cable, as that's the only variable, I have read that others have got the SanDisk 32gb to work with the Nexus 7. I'll try another cable...
Got my new USBOTG cable, and the Sandisk 32gb now works. My external HDD still doesn't work (unless plugged into hub), but that's not too surprising. The new cable is this:-
Afunta(tm) USB 2.0 A Female to Micro B Male Adapter Cable (search on amazon.co.uk)
The old one works with most of my USB sticks, but is maybe not as solid in terms of build quality, as the new one is much tighter. The old cable is this:-

USB OTG Output current

Can anybody test the Note 3 with a USB OTG cable and external hard drives?
If you are rooted and using the app "Stickmount" https://play.google.com/store/apps/details?id=eu.chainfire.stickmount, one should be able to mount a FAT32 partition to their phone.
If you don't want to format your hard drive to FAT32, then using the app "Paragon exFAT, NTFS & HFS+" https://play.google.com/store/apps/details?id=com.paragon.mounter would allow to mount another partition type.
It would be very interesting to find whether the Note 3 can provide enough power to external hard drives (portable hard drives with no included power supply) during the read and write processes.
Even though a USB 2.0 OTG cable is all that is available (to my knowledge), it would still be very useful to have the full 500mA available on the USB 2.0 portion of the Note 3 USB port.
Most smartphones have much less than 500mA on tap for the OTG connections.
I was able to connect a 500 mA (2.5" 5400 RPB SATA) from ADATA hard drive to the Note III!
Really unexpected. Connected the OTG connector first, then connected the drive to the female USB A port on the connector.
On my Note II it would try to spin up, squeal and spin down.

Awesome, good to hear. Have you tried large file writes and reads to and from the drive in order to see if it is able to complete a write operation? If it can handle writing a bunch of data without corruption, then it very well may have full 500mA output capability.
thanks for the report!
I was able to delete a file from a FAT32 formatted drive. No need to install anything extra. Even though there is a 4GB file size limit, FAT32 is unfortunately the only format everything can read without additional software.
Even windows can't read Ext3/4 without additional software - and the software isn't just click and install good to go.

Just wondering if anybody has any more info on the Note 3 output current? I hope it can power a Western Digital My Passport 2TB 3.0 as well as some DACs, such as the Musicstreamer II without providing insufficient power to those devices.
I went into a store and found that it will power a Western Digital 2tb my passport drive. It wouldn't read NTFS, so either root or exFAT may be required.
I confirm works well on my OTG usb 2.0 from S 2

[Q] USB Storage questions

I was wondering, what's the largest size USB stick or drive that somebody has succesfully mounted to one of these? I currently have a 32GB SSD on a USB enclosure connected to mine and it works fine but I'm looking to have a lot more storage (my music collection alone is about 60GB plus I'd like to include some videos). I tried hooking up a 500GB USB HDD that I have but it didn't work (I'm asuming because the HDD takes more power from the USB port than the SSD) so I was thinking of buying a large USB stick but I wanted to make sure it would work before wasting my money.
Additionally, I'm able to connect a USB stick to either one of the USB ports, but I can't connect 2 USB sticks at the same time (one on each port obviously). Is this normal behavior or is something wrong?
FYI, my unit has an RK3188 CPU and I'm using Malaysk's ROM (I couldn't do it on the stock ROM either so I don't think it's the ROM).

Formatting the SD card as internal storage

Has anyone formatted a micro sd card as internal storage? If so how do you like it?
Clearly devices with usb C ports and usb 3.1 should be much better performing, but I was wondering what issues if any people are seeing with the current hardware on the Moto X Pure with micro usb and usb 2.0.
The only Android device I've formatted external storage as internal storage on so far is the Nexus player. On the Nexus player I'm using a 64GB usb 3.0 flash drive through a usb 2.0 hub through the micro usb port on the back of the device, so the speeds are limited, but it seems to perform pretty good I think most glitches/issues I have with the Nexus player are unrelated to the file/storage transfer speeds.
I believe the micro sd slot is still connected though usb 2.0 on the Moto X Pure so I imagine it should have similar performance to what I see with the Nexus player with slightly less latency not having to go through an additional usb hub.
If your on marshmallow you get prompted as to what to do with your external SD card. Either keep it as portable storage or format it as internal
