i have done alot of nonsense to my tablet, but for some reason i don't think my tablet is recognizing my internal sd card as memory. I tried downloading a file from a website and it said that i needed an sd card to download the file...this never happened to me before recently. I remember the tablet recognizing the 16 gigs of internal memory as essentially an sd card on the system. I think it now recognizes it as maybe internal memory and needs to show it as an sd... i don't know for sure... is there anything i missed. do i need to partition something? i just flashed cyanogen 7.0.3..
so it happened just after flashing, or already before? in cm in a file manager do you see sdcard?
Dunno about thekafka, but I have just flashed the same version of cyanogen to my G-tab, and am now experiencing the same issue. This did not start until after the installation. File Manager and CWM do find the SD card.
Is there an optimal partitioning scheme to use when flashing this ROM?
In CM-7.0.x, the internal SD card is mounted at /mnt/emmc and the external SD card, if one is attached, will be mounted at /mnt/sdcard. They're not trying to make things difficult for new users--it's just what's sensible for the wide range of devices that CM runs on: internal SD cards at /mnt/emmc and removable SD cards at /mnt/sdcard, whether on phones (remember, most phones don't have internal SD cards) or tablets.
If you're coming from another ROM where the internal SD is at /sdcard (or /mnt/sdcard) and the external is at /mnt/sdcard2, you, and some of the applications that you use, might get confused.
It's easy enough to switch the mount points so that internal SD is at /mnt/sdcard and the external will be mounted under /mnt/emmc. There is even a CWM-installable zip file floating around to do this easily. Search around here or at the cyanogenmod gtabet forum.
Thanks for being helpful and smart and stuff.
Here's the address of a thread with fixes, including the ZIP file that rajeevvp mentioned:

I have searched and I have not been able to find my answer. I have looked in the settings and I have changed the settings.
But it doesn't matter how I set it up it always install the files onto the internal memory .
I have a Micro SD card that I would like to install most of the programs
Is there a way to install the programs onto the external Micro SD card or a move them there after you download them ?
I remember reading a thread or two about moving apps to the SD card ... have you tried searching on "move apps to SD card"?
Heh! The grass is always greener on the other side isn't it?
The easiest solution to your problem would be for you to install CyanogenMod. It likes to install everything on the external SD card--so much so that people resort to hacking /system/etc/vold.fstab to get it to use the internal SD card instead.
You might care to look at that file on your ROM (I'm assuming its VEGAn-5.1.1 or one of the other Froyo-based ROMs). The vold program uses that file to determine where disks should be mounted. You can switch only the device paths in that file to get vold to mount it the way you want it--external SD card as /sdcard and the internal SD card as /sdcard2.
If you just want to manually move files from place to place, use Root Explorer.
I have a few questions about app install locations for the g-tablet. There are three places where apps can go: 1. internal memory, 2. internal sd card, 3. external sd card.
For internal memory, I can see the installed apps (the apk files) at /data/app. I cannot find any evidence of any apps installed on the internal sd card (do they stay packaged in the apk file or get exploded out). What directory do they get put into on the internal sd card? In case you're wondering, according to App 2 SD Pro, I have 10 apps installed on the sd card.
Is there a way to install apps on the external sd card? Everything that I've read about and the sd card app managers that I've tried only work between the internal memory and the internal sd card.
Hmmm...nothing but crickets. Not even a question for more information? Well, here is a little more anyway. The tablet is rooted and I have tnt-lite 4.4.0 installed. I'm using Root Explorer to browse around in the file system.
This discussion might help, somewhat.
Yes, that other post was somewhat helpful. I can see the apps that have been moved to the "internal" SD card are at /mnt/asec with Root Explorer (I didn't have to unmount either...but the .android_secure folder did show as empty).
A couple of other questions for you:
1. Are you using a remote Linux machine to do those find commands or is there a way to get to that command line on the g tablet? I only have Windows so I may be stuck there.
2. Unmounting the SD card in the Settings will unmount the "external" SD card, right? not the "internal" SD card?
3. Do you know anything on my other original question about the "external" SD card? Can we move apps there some how? If not, I'd be game to try to write an app that will do it but my guess is that if there isn't an app that does it already, its probably harder than it seems that it should be.

If you unmount the SD card (internal or external -- depends on the ROM), you will see stuff in /mnt/sdcard/.android_secure/.

I use a telnet session into the gTablet, but, you can run the commands either inside a Terminal emulator or via adb. It usually doesn't matter how you run the commands.

Depends on the ROM. In CyanogenMod, the SD card is the removable SD card. The internal non-removable one is called "emmc" (mounted under /mnt/emmc). Other ROMs have /mnt/sdcard and /mnt/sdcard2 (Froyo/GB) or /mnt/sdcard and /mnt/external_sd (Honeycomb ROMs).
3. Do you know anything on my other original question about the "external" SD card? Can we move apps there some how? If not, I'd be game to try to write an app that will do it but my guess is that if there isn't an app that does it already, its probably harder than it seems that it should be.

CyanogenMod does what you want by default. As I mentioned above, for it /mnt/sdcard is always the external removable SD card. So, everything "moved to SD card" ends up on the external SD. If you want other ROMs to behave this way, you'll have to change some of the /init*.rc files and the /system/etc/vold.fstab file and change what gets mounted as /mnt/sdcard (ie, which device is assigned the "sdcard" label). Look around, the changes are fairly obvious.
My recommedation, however, is to just install CyanogenMod and avoid the /init*.rc and vold/fstab hackery.
Good information. Huge THANKS !
One last question (hopefully)...if the SD card in CyanogenMod is the external SD card, I guess I have the reverse question for it. Can/how do you move apps to the non-removable SD card?
I guess what I'm getting at is I have a 16 GB internal, non-removable SD card and a 16 GB removable SD card that I'd like to maximize the use of. I'm not stuck with only being able to put apps on one or the other depending on the installed ROM am I?

Heh. What started as a simple question about App install locations has now progressed to low-level mucking about with the system. What next--RAID using the SD cards?
To answer your question, with the standard, unmodified ROM you are stuck with only using either one or the other. But, since Android is based on Linux, (and since we have the source code for most of the programs on the system), it can be made to do a lot of non-standard things.
I'm pretty sure that the system can be modified to use both the internal and external SD cards for App installations, but, this will need a fair bit of customization of the ROM. Which means that if you switch ROMs or even upgrade the current one, the setup will have to be redone again.
Therefore, my recommendation, is that you use one of the SD cards solely for app installs and the other only for storing media/books/whatever. 16GB only for apps is a fair bit of space, I feel.

Well, I had hoped to avoid the mucking about part and that one of the available ROMs already had the ability to put apps anywhere but it sounds like that is not the case. I guess I wasn't clear with my original question.
Anyway, thanks for all of the answers. I'll stick with what I've got for now. At some point I may play around with some things and see how thoroughly mucked up I can get it.
I don't understand storage on Android and how it works. I would be grateful if someone could explain it.
Normally I thought that Phone memory refers to the storage space on the phone (like ROM) that was fixed and not removable. SD card is the microsd card that I physically insert into a slot on the phone. However, it seems that Android has 3 types of storage: Phone, Internal SD and External SD. Is this correct? I would appreciate if someone could clarify. Also, when I do move Apps to SD card on my CyanogenMod ROM, it seems to only move them from phone memory to internal SD, not external SD. As a general rule, is is better in terms of speed to keep the apps on internal or external SD? I don't want to keep in Phone memory since it is quite small, only about 1.8 GB. I should point out that I am using a Class 10 MicroSD, so it should be quite fast, or so I've been told.
What you refer to as Internal SD is probably not on the SD at all but read/write memory in the device itself. Basically built in storage that's an addition to the read only memory where the important stuff is.
As an example, the Omnia i900 had ROM + 8GB Storage in the Phone, with whatever you wanted to add as External SD. Plug the Omnia into a PC and you had two lot's of storage that you could drag and drop files to.
Basically you have 3 things:
ROM (Read-Only-Memory): This is where Android itself resides. All the OS stuff is here.
Phone Storage: You may consider this as the phones HDD. This is where all the apps/SMS/MMS/... are stored. (This is usually not meant to be accessed by the user to place files there, thats what the SD-Card is for)
SD-Storage: Your SD-Card where you can put everything you want. Music/Pictures/Files...

Is it possible to run apps off the SD-Card? When I use an app like App2SD, does it actually copy to the SD Card or just to the Phone storage? This is what confuses me, because I selected 'move to SD' on my phone (I'm using Cyanogen 7.1.0). But its still in the Phone Storage. I know this because when I put the SD card into my laptop, it does not show any of the software files.
When you move apps to the SD not all data is moved to the SD. The phone needs some files on the internal storage to run, since it needs to know that the apps are installed on the phone. When it needs to run it'll find the executable files in the internal storage, and run the data files from the SD card. Much like on a computer when you've installed an application and install it on an external HDD.
Apps you move to the SD will be moved to /Android/data/ and /data i believe since i have quite a bit of appdata in these folders.
I've installed Hyperdrive via SafeStrap today. It seems that when you create that Rom Partition, the OS seems to have been configured so that "SD Card" is actually internal device storage and in order to actually get to the External SD Card I you have to go to Root -> Storage -> ExtSDCard directory.
Also, when I plug it in to the computer, all I can see is the External SD card and this new "fake" SD Card partition in the computer. I can't even get to the Root of the phone.
The problem is things like Pictures and some applications only allow you to choose "Device" or "SD Card" for storage and no matter what you choose it's going to the same place and this virtual SD Card Partition is almost out of space!
Help!
Any help?

That's the way the Stock ROM works - /mnt/sdcard is the internal storage, /mnt/extSdCard is the external storage.
You can't mount the root because it's a Linux EXT4 filesystem. Windows doesn't understand it. Again, that's normal behavior.
My pictures, music, Ti Backup files, etc. are stored on my external SD card, so it's quite possible to do that.
Fixes and Question
Wrong thread, could not delete. Sorry.
upgraded to marshmallow and had both the internal sd and external sd as one (using it as storage)
This turned out to be a bad item and the external sd failed (possibly due to too many reads and rights)
I noticed my internal sd card stopped being able to install apps. On further inspection in Root Explorer external sd card is a folder, but 'sdcard' almost looks like an inaccessible link/normal everyday file. Pressing it in REplorer says that it's not mounted. Yet it is the internal sd card...I can also see how much space its components are taking up under 'storage' in Android OS.
My question is how do I fix this? Most apps get installed to internal sd. I have read on XDA that sometimes kitkat would make inaccessible/encrypt the internal sd card, how do I diagnose this is my problem ,and if I find out it is,how do I fix it?
