External Hard-drive

Hi,
I was looking at some wireless hard-drives to use when I'll receive my TC and was wondering, because of the high-price of these, is it possible to connect an external usb hard-drive to the TC with a USB-miniUSB adapter cable?
Will it be like plug-and-play?
Thanks!
It doesn't have a USB host feature unfortunanlty.

[Q] USB OTG mounts microSD via USB adapter?

I use the USB OTG cable to mount USB flash drives on the Galaxy S II, no problem. I tried putting a micro-SD card in a USB adapter and mounting that via OTG, but the micro-SD card is never recognized. I get no notice of media scanner running, etc. Yet, this same USB/micro-SD combo works fine in my laptop. Any suggestions how to get it to work with the SGS2?
Actually, this worked with a different, better quality USB-microUSB adapter.

Connecting HD by USB

Hello there,
I have a problem when trying to connect my portable HD (250GB) through USB adapter, it say that is not possible to conncet. I though the problem was the adapter, but not because I could connect a regular USB memory.
Anyone has been this problem, and What was the solve?
Thanks in advance
My guess is that the drive is in NTFS format and not something Android can read, like FAT32.
It's either the file system as mentioned by steckums or the usb adapter doesn't provide enough power for the hard disk to run.
Almost all usb hard disk drives require "high power" from the usb port which the adapter can not deliver. It should say so in the error message. You need a powered usb hub to connect a usb drive to the Tab.

Thanks for reply, if this is the cause will be imposible to connect my HD? or if I connect a hub to the adapter the HD will works?

Yes, the following has been reported to work as long as the HDD is formated to FAT32:
USB HDD - powered USB hub - USB Adapter - Galaxy Tab 10.1

I'll try it, and report
I tried but didnt work.
I connected the HDD to regular hub and nothing, i never know what is a powered hub. Then a reformat the HDD to FAT 32 and the tablet was not able to start.
The last test was try to connect a powered HDD and this one was reconized by tablet but the oroblem was the format.
In conclusion the problem is the power and the format of HDD.
Thanks for your answers

Usb otg + laptop hard drive + usb host

Hi, i wanted to know if it was possible to connect my internal laptop hard drive via usb otg and read the files from it.
I believe i will need a usb host to power the hard drive via mains and an external caddy to hook up the HD. Could anyone confirm if this set up will work and whether it will be at all possible to read the files of the hard drive.
Thank you for any help.

First of all, you need a SATA-to-USB or IDE-to-USB adapter to connect the internal HDD via USB.
It depends on yout HDD if the S2 can serve enough power. Try it out. If it does not work, you need a self-powered USB-Hub between S2 and HDD.
Hi, thanks for the reply. I went to a computer shop where they used an external caddy and i tried to connect it to the usb otg cable but it didn't recognise the hdd.
Do you have a recommended self powered host? Or will any (cheapest option) on ebay suffice?
Thanks again

[Q] Connecting to external HDD

I was wondering whether I could connect an external HDD (powered) to XTZ. Do I need an OTG cable or just a plain microUSB to USB adapter will do the job?
OTG cable, like on all other Android devices with Micro USB.

Thank you. Well bought me an OTG cable. Seems to recognise keyboard, mouse and usb flashdisks but whenever I connect an HDD, either selfpowered or powered through the usb port, it is always recognised as damaged USB storage… then asks me to format it. In case I choose to format it nothing happens. I should mention that this happens with FAT32 HDDs too. Isn't XTZ capable connecting to external HDD?
Did you solve the problem? I going to buy XTZ but for me is essensial chance to connect external HD
It is possible and works, but it only if the HDD has an own power supply.
No I didn't manage to access ANY type of HDD self-powered or not and any kind of format i.e. Fat32, exFat, Ntfs etc. I only managed to access usb sticks and input devices (mouse, keyboard).
I am rather disappointed from this issue…
Can I charge my cellphone if I connect it to the tablet with the usb host Cable ?
Using the tablet as an external battery for emergencies. Thanks

Very unlikely.

Which one did you buy? I bought a pack from amazon but none (of the 4) worked. I only tried using it to sync a ps3 controller though.

I have the 16GB WiFi version and I have no problems at all reading external media. Here is what I did:
Before starting I reformatted the HDD with "exFAT" file system using a regular Windows PC. I did a full format, not the "Quick Format" option. This took a looooong time to complete with the big drives. In the XTZ I installed "ASTRO" File Explorer from Google Play to perform the file operation. After that I was ready to go. I already tested with copying a 20GB file and it worked fine.
The same procedure worked for:
- 32GB micro SanDisk
- 64GB micro SanDisk
- 128Gb USB pendrive (OTG cable needed to connect)
- 300GB USB external HDD (OTG cable + powered USB-hub needed to connect)
I hope this helps
