after installing I can see drive as sda1 - however when i try to mount .. i get error mount failed:

Does this mean that i need to root my device ?
[Acer Iconia A500] hellcat82:
Yes, this only works on rooted devices
[Acer Iconia A500] kxs783kms:
I'm rooted(verified by removing files from system/app with Root Explorer) but I'm getting the same error message.
[Acer Iconia A500] bodysoda:
Oh yes.. thanks.. I have root'd my a500. I can access all the files on my 1tb verbatim hdd.

Thanks to who ever wrote this ntfs app.... lol...this is going to make my I pad friends jealous :cool:

Follow the "How to root the Iconia A500" guide

Install the NTFS Mount app on the first page

Plugin NTFS USB External HDD/Thumbdrive

Launch NTFS Mount

Select drive (sd*)

Click mount button

Navigate to /mnt/usb_storage in a file manager

I can't install the apk

get: Application not installed

and yes I am rooted checked with root check, have more than 1Gb free space,

have the same problem with some other apps too???
[Acer Iconia A500] GeneralSmart:
I dont understand...i rooted Acer A500, isntalled apk can start it, getting su-rights, but dont find any of my ntfs memory sticks....:confused: is it just supporting hdds???
[Acer Iconia A500] hellcat82:
It works with my USB memory stick. Perhaps follow the manual instructions? Do you not see the drives in the dropdown list?
[Acer Iconia A500] atomicwedgie:
I posted about this a while ago. For some reason you need more than 1 gigabyte of free space to install applications. Free up some space and try again.

Yes, thats the problem, i dont see any drive in the dropdown menu...any suggestions??:o i tried 2 usb memory sticks, some card readers....
[Acer Iconia A500] hellcat82:
Can you try this in a terminal windows

ls /dev/block

Do the above without and without the thumbdrive plugged in and report the differences.

For example if I plug my NTFS thumbdrive in the extra items I get are:

sda

sda1
[Acer Iconia A500] Euclid's Brother:
Totally Awsome. I didn't realize it didn't have NTFS support when I bought it and was intending to use an ext hd with my kids vidoes on them. This works GREAT! Thank you so much.

Do you take feature requests? With a usb hub, it actually recognizes additional usb drives (sda1, sdb1, etc.) Would it be difficult to allow custom mount points for NTFS drives. Perhaps mount sda1 as /mnt/sda1 and sdb1 as /mnt/sdb1, etc. That leaves usb_storage open for a FAT32 drive. Then we would be able to copy files from one drive to another..

Thanks
[Acer Iconia A500] rushless:
Yes, I noticed this too and confirmed by adding and removing to the 1gb free threshold. I wonder if this is a bug or a Honeycomb constraint due to dynamic storage? Apple aint' go this problem... Just sayin'. My iPod 4 64gb has 712mb free ATM.

Be interesting to know if this is a bug or how Honeycomb rolls.
[Acer Iconia A500] hellcat82:
I originally wanted to add multiple mount points, but time got the best of me so I packaged what I had. When I get a few minutes spare I'll have a go at implementing what you have suggested.

[Acer Iconia A500] Vereynn:
Works like a champ for me, other than I get Unmount Failed: when I try to dismount the drive I'm testing with. No errors or consistency failures when I plugged it back into my Windows box, so I'm guessing it unmounted on the drive side but a handle got left open somewhere on the tablet for a little bit.
[Acer Iconia A500] GeneralSmart:
do i need to type stuff in any kind of terminal or just like the tutorial says: root, install apk and mount?

Edit: got it working now...dunno what the problem was....

[Acer Iconia A500] filnet:
Perfect, full access to my external 500 GB HD, no more copying for some of my less frequently used files.
[Acer Iconia A500] JackMetal:
Many thanks for this! Works great. Quick question: Is there any way to 'automate' the mounting just like for fat drives?

Now, if I could just get access to ext3/ext4 and TrueCrypt containers, I'd be perfect! :-)
[Acer Iconia A500] hurrpancakes:
For some reason, my external hard drive will mount, but my flash drive will not
[Acer Iconia A500] psychotropic:
If you're having unsucessful unmounts, it's because an app is still using something on the drive. Mac, Unix, Linux, or any Linux-based system will fail at unmounting drives if something on the drive is still in use. Close any programs that could be actively accessing drives and try again.

This, kids, is why I canceled my pre-order for the Asus Transformer and bought the Acer Iconia. USB support right on the tablet, no accessories required. You damn Australians are just wonderful. Your social scientists have saved me with their journal articles on my last social work paper and you, sir, have saved me with clear straightforward NTFS access on rooted devices. This country needs more recognition.

Now if you can get your country's tourism department to remove that OBNOXIOUS tourism video of people singing that seems to air several times per evening, we'd be in business.

[Acer Iconia A500] hellcat82:
Theoretic multi-mounting

I've updated the app which now creates mount points based on the drive name so theoretically it can mount multiple NTFS drives. It now also has an option to add symbolic linking to root (/sda1).

Uploaded the new version to the original post
[Acer Iconia A500] BrainMcFly:
i have tried it, rockplayer plays my movies from a mounted usb Harddrive (NTFS formatted). Plays all Formats but having Problems with MKVs, because it dont fully supports all x264-freatures (choppy playback and tearing or blocking errors). I think its because the Hardware of the Iconia just supports some special encoding-features.
[Acer Iconia A500] Euclid's Brother:
Thank you so much. I look forward to giving it a try.
[Acer Iconia A500] 00mred00:
Will try closing apps...I got this to work once...then after the tablet went to sleep it wouldn't work again.

Will toy with it more tonight because it sure would make life easier...I've been converting/shrinking movies to play on the ps3 fat system for years
[Acer Iconia A500] hellcat82:
I have noticed a bug of sorts, there are some series of events that stop the usb drive from being detected by the tablet after a while. I was unplugging replugging the drive then all of a sudden the usb port wouldn't detect the any drive I plugged in nor did dev entries appear. A reboot fixed it so it's not a big issue and I did unplug and plug it in around thirty times. Just something to keep in mind.
[Acer Iconia A500] anubis13:
Installed the NTFS app. D

Drive isn't even detected by the tablet.

FAT32 formatted 2.5" 500GB drive also not detected.

Formatted the drive to only have 32GB and FAT 32, still not detected under the USB_STORAGE folder.

Rooted, using Root explorer.

the only thing that works through the USB port is a keyboard.

Haven't tried a thumb drive yet.

I'm starting to think I have a defective unit
[Acer Iconia A500] hellcat82:

[Acer Iconia A500] hellcat82:
Your drive is on sda1 and sda5. Multiple partition? Either way both partitions should mount if they're ntfs.

Your tablet is definitely detecting the drives.
[Acer Iconia A500] Euclid's Brother:
I haven't had a chance to fully test it yet with a usb hub and multiple devices, but it did mount /dev/sda1 under /mnt/sda1 successfully. (using NTFSMount1_2.apk)

After a few minutes i noticed that it "lost" it. NTFSMount said it was still mounted, but the files were gone. Unmount was successful, but it would not mount again until i pulled the usb stick and re-insterted it. I'll keep my eye on that to see if it occurs again.

EDIT: I haven't nailed down yet when it happens, but it seems to "lose" the mount point after a few minutes, then re-dectected uner the next dev name.. (etc. sda1, sdb1... i'm now up to sdd1 all from the same USB thumb drive). Rebooting allows it to find it again as sda1.
[Acer Iconia A500] hellcat82:
hmm that's strange, I'll have a look into it. Did you get the same behaviour from the original version?

Have you enabled symbolic linking in settings? Can you toggle it and see if you get the same behavior?
[Acer Iconia A500] Euclid's Brother:
No.. i didn't get that in the original version. I skipped the middle version you posted and went to the last one. I did not try the sym link option. I'll give it a try and report back.

I'll give the other version a try too and see what it does.
[Acer Iconia A500] Euclid's Brother:
i can duplicates the issue now. It's when the screen turns off. Either via switch or by being idle too long. If you turn the screen Jack on within a few seconds, it stays mounted. Otherwise, a few seconds after thebscreen goes off, the thumb drive led will start flashing and it will unmount. Next time it will detect as sdb1.

Gonna try the old version.

Edit: same happens in old version. I guess it's turning off the USB ports w/o unmounting.
[Acer Iconia A500] Euclid's Brother:
@hellcat

In your next release could you add a button to refresh the device list? When this screen off unmount issue occurs, the only way i can remount is to kill NTFSMount and run it again.

Ultimately, Auto Mount/Unmount would be great, but I have no idea how difficult it is to detect w/o constant polling of the dev list.

Thanks.
[Acer Iconia A500] sto88:
Hi,

if it possibile, someone can edit the topic and edit the first post with the guide to add ntfs support... I think if it'll be in the first post it will be easy to read and stay updated with the future versions of this wonderful mod XD

Thank :D
[Acer Iconia A500] hellcat82:
Actually if you change the orientation of your screen the whole app will reload, I know it's more of a bug than a feature but it works, at least until I get some time to put a refresh button on it. :D

Dear Hellcat82,

I downloaded very 1.2 to my new and rooted A500. I have Dolphin HD. When I run the apk, I get "No application is found to run this program''. I tried very 1.1 and the same. I downloaded other apk from dolphin and all worked. I even downloaded the G-viewsonic and it ask me if I want to install. I did not. I just want to verify that I am able to install apk.

Any idea to why? I am rooted with Gingerbreak 1.2 and couple rooted programs are working fine. Thanks for the help.

Dr. Sam
[Acer Iconia A500] Ramasoft:
The same problem. See my post #73.

Dr. Sam
[Acer Iconia A500] hellcat82:
There should be no reason that you cannot install the apk, if it's asking for a program to open the apk it's most likely a corrupt download. Maybe try downloading using a desktop or the default browser? Or alternatively if you PM me I can email you the app.
[Acer Iconia A500] Euclid's Brother:
After downloading, you have to use a file manager and go to /sdard/download and run it from there. It will ask what you want to run it with. Choose application manager and it should give you an option to install. G'luck.
[Acer Iconia A500] Ramasoft:
Thank you very much. I shut down the device. I went to the download folder. I clicked on the file and it did install without any problem. Thanks.

PS. I am using a program called Mini Info. In the past, it showed both external SD and the internal SD information. In the A500, it only show the internal SD information. Any idea to why it does not show the external SD information. Thanks.

Get all the time…. the “ Application not installed “

@Ramasoft you get it to work ?
[Acer Iconia A500] Euclid's Brother:
probably because it's not using the right paths. The tablet mounts the external sd card at /mnt/external_sd. That app has probably not been updated to look there. Email the developer and see if they will update it.
[Acer Iconia A500] hellcat82:
Well after a few nights of hard labour I've got some nice new features which just need a little bit of personal testing and tweaking before I post them up.

The big new feature is the ability to mount NTFS SDcards as an external_sd. I've tested it and it's all working I'm just not yet sure things like Music will be able to detect content on it.

At some point it will have the ability to mount NTFS SDcards on boot as well.

Edit: It's not looking like the music player will detected the NTFS mounted SDCard, so it's not loading music from it. I'll keep looking into it, hopefully there's some way to force the Music player to scan it.

Edit 2: Nevermind got it all sorted, now music detects the added media.

Man you are a legend i have had problems playing avi files from externalsd but they will play from internalsd now i can mount sda1 500 gig hdd and play all my files from it until now i have not been happy with my A500, now i love it thank you man :)
[Acer Iconia A500] EwanG:
I have a Xoom flashed with Tiamat's 3.1 and his 1.4.4 kernel. I just got a Motorola Camera Connection Kit cable which I understood supported Host Mode. I installed the Mount NTFS 1.2 apk.

I then attach my USB cable to my 4TB Hard Drive on one end, and to the Motorola cable on the other. I turn on my HD and let it spin up. I then attach the Motorola Cable to the Xoom and wait for a full minute to make sure it is getting time to see the drive. I then run the Mount NTFS program. When I run it, it does not see the HD and gives me no Devices to select.

Is the problem here the Motorola cable, the order in which I'm doing things, or something else?

I'm getting ready for an extended business trip, and would like to avoid having to get a laptop or PC just to be able to work with files off my external HD. I thought I had the answer here, but... ???
[Acer Iconia A500] netarchie:
Great app , thanks a lot!

Just one question, Do I have to unmount my drive everytime I remove it from the USB?

The reason I ask is, I had include 'my pics' folder on the external 500 gb hdd for quick pics to display my pics, when I remove and replug my HDD , quick pics says the hdd is not mounted and the USB mount app mounts with a changed name, i guess? everytime.

Sorry not a linux guy!

Thanks again for the wonderful app.
[Acer Iconia A500] hellcat82:
Yes you should unmount before removing it, otherwise Android will assume the drive is mounted and give the drive a new device name when you plug it in again. When 3.1 is release on the iconia I will add functionality that will detect when a drive is unplugged and then unmount it automatically, until then it's manual I'm afraid.
[Acer Iconia A500] hellcat82:
Can you run the following commands in terminal emulator or adb shell

Prior to plugging the hdd in type

ls /dev/block

Take a note of what you see there

Plug the hdd in and type the same again ls /dev/block

Can you tell me the differences,you should see some additional devices like sda, sda1, etc

Cheers,

Dwayne
[Acer Iconia A500] EwanG:
With the 4TB drive, there is no difference whatever - as if it doesn't recognize that an NTFS drive has been attached. I then got a FAT32 formatted USB Stick, and saw that /dev/block then added a sda and sda1 entry, and I was able to access the stick through usbOTG.

So, cable seems to be fine, and host mode seems to work for FAT32. I will try to format the stick as NTFS to see if I can then see if it really is an NTFS issue rather than a 4TB disk issue :D
[Acer Iconia A500] EwanG:
Well... that was several types of ugly...

Formatted (low level) the USB stick as NTFS, and confirmed I could create directories and read/write files to it on the main PC.

Hooked it up using the Motorola Cord, and did see the sda and sda1 devices appear. However, Mount NTFS did not present any devices to mount, and going to usbOTG gave a message that it couldn't be accessed.

So... bit of a suspicion that there is an issue with Mount NTFS and 3.1 or Tiamat 1.4.4 or possibly both.

If I get time tomorrow, I will see if I can find a smaller external USB drive just to make sure the stick isn't adding to the confusion here.

FWIW...
[Acer Iconia A500] djyoshii:
Managed to install the app fine, and then successfully mount one of my NTFS drives.

However when i then go into a file manager, "USB_Storage" still appears as empty.

Am i missing a step here or something?
[Acer Iconia A500] djyoshii:
Ok, so i installed the first version and it works perfectly fine.

Tested it again several times with the other two, and no matter what i tried neither would let me view the hdd, although they both successfully mount the drive.

not sure what is causing it, but yeah. Try out the original version for anyone who had the same issues as mine :)
[Acer Iconia A500] hellcat82:
The first version works a little differently to the second. The second version doesn't mount to usb_storage. This is due to the fact that if you mount to the same place i.e. usb_storage, you can only mount one partition at a time. The second version mounts under the device name which means if you have a hub and 4 drives you can mount all of them at the same time.

Under the second version your drive will be mounted at /mnt/<drive name>, so if the name of your drive is sda1 it will be mounted at /mnt/sda1.

Also if you enable symbolic linking in the settings it will also be available at /sda1

Hope this helps
[Acer Iconia A500] apkanthony:
you have to choose the "sda1", not USB storage :)
[Acer Iconia A500] djyoshii:
oh i didn't take notice of any other device names in the file manager.

...wow now i feel stupid lol

I'll try out the 1.2 tonight and have a look again :)

Thanks again mate!
[Acer Iconia A500] EwanG:
As near as I can figure it, it looks like NTFS Mount (or the combination of that with Tiamat) has an issue with drives that are self-powered. It's as if the OTG is looking for the current pull over the USB to tell it that something is attached.

My "smaller" 1TB drive was similarly undetected.

So it looks like whether an external USB drive is NTFS or FAT32 that it will not be detected if it isn't powered by the USB connection. On thumb drives, I have been able to reproduce that while it will be recognized even if it is formatted as NTFS, that it kind of goes "haywire" when it tried to actually load a thumb drive using NTFS. In fact it appears that the Xoom gets confused about the thumb drive and the normal "SD" card which is the internal storage.

Since the setup works just fine if you use a thumb drive formatted as EXT2 or FAT32, it appears that the cable is working in those cases.

Not sure where to go from here, but it seems obvious that I am not going to be able to use a larger drive from the Xoom. Oh well...
[Acer Iconia A500] hellcat82:
Hmm, I don't have any such issues on the Iconia. My 2TB external self powered drive works fine. It could be 3.1 or the Xoom itself. I don't have a Xoom to do any testing on so I can't really help unfortunately.

If anybody in Melbourne wants to loan me a rooted Xoom for a couple of hours I'd be more than happy to look into it :D
