[q] add additional space to a100 - Acer Iconia Tab A100

This is in a different forum for the Vizio Tablet that mounts the external SD card the same way. Someone who is a dev or at least smarter than myself might confirm that this will work.
You could change the mount points of your internal and external sdcards

Would this work? I know apps2sd given error.

This doesn't work because of the way /mnt/sdcard is being mounted (through the init) rather than vold.fstab. The only way to change it would be to build a custom rom and take it out of the init and add it to vold.fstab or just reverse it and add the entry that is in vold to the init.
Problem is the init can't be changed, it's re-written every reboot. I'm working something though that might help, just don't have it ready yet.

[Q] Link 2SD

I have updated to CM7 Mod
then i created a 300mb ext2 partition through PC
then after that i manually linked all of the apps to the ext partition but i still have 1MB left in the internal storage even after linking

Hello there,
did you reboot the phone? Did you link only apk or also dex and lib files of the applications?
How many apps are installed? You can view apps that are on the SD card but not on the ext partition. maybe they didnt get linked?
yes i did reboot the Mobile..and i have linked the dex and lib files too
there are 46-49 apps installed
yes it says ---> Linked
when im on sense, im using DT a2sd (ext4)
when im on CM base, im using S2E (ext4). I got more than 100mb free space after more than 50 apps installed.
so should i delete the old ext2 partition and make a ext4 one?
Use flashable data2sd script...it worked for me

It doesn't really matter.
I would suggest factory reset, then installing Link2SD.Open it, and tick "Auto link".Then install all apps you need, and you're fine.
By the way, that internal storage information from phone is not correct.
For example, I have 50 apps installed with 30mb free internal storage.Then I delete one app (2mb), and the phone shows 50mb free.So, it's not correct.Don't know why, but that's the way Link2SD works.I got used to it.
Anyway, if you have Class 6 or up sdcard, then I'd suggest using data2sd, otherwise, stick with Link2SD.

but when i started using link2sd for the first time i always used to have 55MB even if i install new apps but now its only 10-15MB

how can you tell what class sd card your using plz ?
I would also recommend S2E, like asdot said earlier.
It is in my opinion the easiest and best solution when you are using CM (7 or 9, both work).
Just install it from the market.
And it is true, if you have a slow SD card I would not use data2sd. The app S2E gives you the option to move apps only, not their data. I use that option and have a very fast phone with basically endless memory

Use antutu to test sdcard read/write speed.
Compare with this(write speed is what's important)

[Q] A2SD question

2 questions
1) is A2SD usually brewed right into ROM's?
2) should I see my internal storage size actually increase if it is working, or does it just make it easier to move things to SD?
One of the reasons I rooted, like everyone else I would guess, is because of the relatively small internal storage on my EVO. I read somewhere that you could get the EVO to think that a 512meg partition on the SD card is actually more internal storage but have been unable to get google to tell me how to do it...

U should get more internal memory
Sent from my PC36100 using xda premium
1) the rom description will say if a2sd is baked in, or if the rom supports it. If a2sd isn't baked then download the zip (which I can post if you want), then flash the rom, then kernel, then gapps, then a2sd. It will reboot 3 times then check the internal memory.
2) it won't show any more internal memory, just that less is being used, as a2sd basically tells the phone where on the SD card to look to find the apps

I'm fairly certain I have it working. I using classic, which has it built in. Think so anyway. I installed an a2sd app and it shows the ext3 partition and that its being used. I suppose that when I start to approach the app load I had before I rooted the phone ill know.
Thanks for the answers guys.

Could do (in terminal emulator)
su
a2sd remove
If,after the phone reboots, you have less free internal memory, you know it worked. After verifying that, then go back to term emulator and
su
a2sd reinstall

[Q] question about Data recovery after formatting

read a lot of threads said that it is impossible to recovery the data as N7105 only support MTP mode while not UMS mode.
but i am thinking, if it is possible to have a apps/ adb shell command that can copy the entire internal storage bit by bit to a external device ( like external sdcard or even a pc using a usb cable). so that i could run data recovery program from that image copied bit by bit?
Enable usb debugging in dev options.
This would mount the external and internal storage that is rhe /data/media and not /data.

problem is, it does not matter if it can mount both external and internal storage, because if it is in MTP mode
there are no any data recovery program can detect the drive
just read that adb shell dd command might be able to do the job.
but as i wanted to copy the entired storage
is it possible that there are a dd command which can output the file to pc directly?
I had the same problem. Then I gave up
Sent from my GT-N7100 using xda app-developers app
i have read many cases but with same fate as utkarsh said 'gave up'
Edit:
There is appl in play store, which can recover, but supports only Fat partition
So try getting your device to format in fat32 still can be help, but really i don't know how
Just i have read some command can remove your partition and you can create it to fat, later formating it again make it exfat
though everything is just assumption and idea, if you want to be creative read and collect information. it will never been risk free.

[Q] how to turn SD into into internal memory?

OK so I looked at a similar thread to this but I don't think I understood nor do I believe its right Ford what I want to do.I was wanting to put stock ICS on my phone but to do so will leave me with (roughly) 20 megabytes of storage left. I have been told there is a way of tricking the OS into believing the SD is internal storage I have looked on the internet and here as well and found nothing therefore I was wondering if you guys could help me out in accomplishing this. any feedback is both welcome and appreciated thanks
flash the rom, flash gapps, and on the first boot go to play store and install mounts2sd, configure it to reverse mount and select apps, data and dalvik. voila

Yes this can be done quite easily using a script called a2sd or another like it.
First you need to create a ext4 partition on your sd card. It's highly recommended to use gparted(look around for guides)
Then flash a rom that has a2sd support. If you want ics/jb, I'd recommend the rom in my signature...it's great and works well with a2sd
Once in the rom, open terminal emulator and type
su
a2sd install
y
n
y
From then on all apps that you install will be moved to your sd-ext partition.
Thanks.

AOSP Kernel & 64 gig sdcard

Is there a kernel that supports a 64 gig sdcard?
Or is there a mod to fix it?
Or do I have to format the sdcard for AOSP?
Please someone answer me
Sent from my SPH-L710 using Tapatalk 2
KT747 supports exFAT if that's what you really want. But if you're using AOSP, you can format the card as ext4 instead and use it with no problems with any kernel. I know CM10.1 supports mounting ext4 SD cards at boot (I use it), and if you're using an AOSP ROM that doesn't support mounting ext4 at boot, check out goo.im, and navigate to invisiblek's folder, and he has a zip you can flash to mount ext4 cards at boot.

Aside from FAT32, no. Since exFAT is proprietary, AOSP can't include it (for the most part; obviously, KT747 had it), and since 90% of users will only use Windows PCs, Samsung has no reason to support Linux filesystems.
In reality, both TW and AOSP kernels work with ext4. The root filesystem on our phones uses ext4, so the kernels have to support it. But since very few of their customers even know what a filesystem is, let alone which one they're using, Samsung sees no need to support mounting ext4 SD cards at boot. The kernel does support ext4, but Samsung went and butchered the vold.fstab so ext4 cards wouldn't mount correctly.
So, for no real reason whatsoever, FAT32 is the only filesystem guaranteed to mount in both AOSP and Touchwiz at boot without hacks (if you look around, there's a guy that's working on getting ext4 cards to mount at boot in TW). It sucks, especially with a 64 GB card.
