[Q] tablet only use the internal memory not my SD card

my a100 only install apps and other crap i downloaded on the internal memory.
but i wanna use my SD card iinstead
internal is only 5 GB i have a 16GB memory for god sake.
is there anyway to make this thing use my SD card
thank you

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

Personally I like to save my external SD cards for backup

No. This question has been answered many times. No, not for running applications. The /mnt/external_sd is intended for multimedia and book files.

Maybe i'm wrong, because i've an 8gb version, but... Did you both tried Link2SD app?
I'm using and it works like a charm... i just needed to create a 2gb ext2 partition on external micro SD...

Just wondering why 2gb only? I assume this is just gonna be 1st (maybe unused?) and the other 30gb is the 2nd partition where you will have Link2sd transfer the app over?

I don't know if this is why he specifically only did 2 gigs but ive heard partitions for ap2sd over 2gigs can cause the sd card to wear a lot faster, but i have never tested myself

I used my phone to do the partition it works great but I don't think it moves data as well
Still have 2 gb free not that much though

Once I find a way to have my mount script run on start up, I'll post this mod that remounts the external sdcard as internal storage. Havnt found a way just yet to remount the internal to the external though.

Sweet that wail be awesome, one question does this only use the external as internel storage or both as the external and the internal together ?
Sent from my Iconia A100 using Tapatalk

As of right now its just binding /mnt/external to /mnt/sdcard so you cant access the internal memory. If I can figure out /mnt/sdcard origional block I should be able to get them swapped so you can use both.
This mod will probably not work on the transformer since it probably has different mount points.

HELP! Problems with new Sandisk 64GB Micro SD

Hi all, this may have been asked a thousand times but I cannot find a definitive answer to this. I bought a 64GB Sandisk Micro SD Class 6 card to use for all my games and stuff. I received it today and tried putting it in my phone. It always shows as damaged card, so I tried the proper steps of pulling down the notification bar, selecting the card and the phone told me it would need formatting, so I clicked format.
But to my dismay the bloody phone formatted the internal USB storage so I lost all my pictures and personal stuff!!!
To add insult to injury, I cannot get this bloody card to format and work no matter what I try. I haven't formatted or partitioned it in my PC, only tried through the phone.
Please, please can anyone help???

Got it sorted. Mods can delete this thread if need be

Sorry, I would have posted it up as soon as I sorted it but I was in a flap trying to get my phone back up and running properly.
What it seems to boil down to is that custom ROMs generally don't format the external SD cards correctly, or so I read somewhere on a thread on XDA (I think it was in the T989 thread or something like that). I used the free EaseUS Partition Manager tool to first remove the partition on the card (64GB formatted to exFAT), then create a new 64GB Fat32 partition. I don't know whether it was necessary but I flashed Samsung standard LP7 Rom to my phone and fully factory reset the phone.
After that was done, I inserted the 64GB card, booted up and went through settings-> storage and erased the SD card to make sure it was formatted correctly for the S2
...and voila
Hope that helps someone out

Get the app undelete to restore your deleted stuff

My SD card was working out of the box with Galaxy S2. I just formatted it and that was it
Just got a Galaxy S3 last week and the same SD was driving me insane with message
SD damaged after copying 59 GB of music to the phone
It was playing music without problem but as soon I restart the phone it would through error SD damaged
After so many tests I just found out that KIES is the one was corrupting my SD card
I tried copying my music with Sandisk data manager, mediamonkey, adding music folders manually and it works flawlessly, restart and not problem
All this app recognize Galaxy S3 quicker than SAmsung KIES, KIES takes a while sometimes to connect to the phone
Hope Samsung update KIES because it doesn't work with GALAXY S3 for uploading 59 gb of music
I was about to send my SD to amazon and get a refund, thanks I didn't do it
Happy days after so many days of testing

Hi guys
I also had the same issue with sandisk 64 gb card but couldnt find any solution n had to get two cards returned.... i dont use kies or any other thing. It also got damaged on first restart after copying 30+gb data on it. Couldnt find a damn solution. Now i have ordered a kingston 64 gb one to c if it makes any difference. Any idea by anyone to check it in a proper manner n maje it properly usable?

A million thanks, I wanted to throw away my 64Gb card and I've payed 70$ for it, but after formatting with EaseUS Partition Manager to Fat32 it works just fine I've tried with Windows a 100 times with no results.

EaseUS Partition Manager def did the job!
here comes the weird bit:
connecting the 64gb micro sd with this

to my pc shows 29 gb in easeUS.
while inserting it in my phone it shows 59.4 gb
using this type of adapter
and connected to the pc with a sd - to - usb adapter:
http://h10025.www1.hp.com/ewfrf-JAVA/Doc/images/550/c01650840.jpg
it will show 59.4 gb in easeUS as well
does that make any sense at all?

I bought this to put into my Samsung Galaxy S3 and opted for the Sandisk name due to previous purchases and reputation. Many people have said to format the card via the phone before use so I did this, or tried to, but it just kept saying that it was in an incompatible format and the process could not be carried out! Ok, a little frustrating but I thought I'd just use the supplied adapter and format it via my laptop. Similar message from Windows - not able to complete the format, the disc may be corrupted!!! I tried this several times on both the pc and the phone and nothing. Very poor in my opinion and it has been returned for a refund.

Thanks! This really saved my day

I ended up getting a 64gig Sandisk super duper card (or whatever it is called). I plugged it into my computer via a USB adapter, and it worked fine. Then I formatted it in FAT32 with the tool suggested in previous posts, and that worked fine. Then as I was copying stuff over (it was still plugged into the computer, my phone was in USB mode transferring data), the transfer froze. I unplugged it, and it was warm. So I tried again, it worked for a bit, and then would freeze. Not sure what the issue was. So I returned it to Best Buy, and they are sending me a new one. Hopefully this one works.
Any tips or suggestions other than formatting it with that utility? Could it really just have been the card itself?

Got one last night, formatted it using the program suggested, no dice. Getting a "damaged card" notification, nothing I can think of is working.
Formatted on my PC, formatted using a Mac, formatted using a linux terminal, nothing seems to work.
Anyone have any ideas on what else I can do to rectify this issue? :/
Or is it safe to assume that it's a defective card?

Hi, know what you're going through. See my post at http://forum.xda-developers.com/showthread.php?t=1698672&page=9
The guiformat tool under the link luigig posted worked great. (I'm too new a member to repost the link here.)
If it doesn't work I suspect you really have a damaged card. There are some known bad batches.

Had an a media scanning issue on my new SGIII (At&T), from my sandisk 64 card. which was previously formated at 32. I used OP's method and so far so good. I also transfered my files to pc and ran defragler on them as i had a media scan issue. I transfrered all pictures with no intent on putting them back since they were from my old atrix. No problems as yet. I will try to transfer from phone to pc to see if i get the freezing. If i do, you will hear back from me. If not THanks OP:good:

try to format it using your pc. (as a FAT32)

format 64GB
What you should do is download a free partitioner program like Easeus Parttition manager. You should make two partitions on your sd card with a max of 32 GB. Format both of them as Fat 32. Once done, put it back in your phone, it is now recognized and you can reformat the card in your phone. It pops up as a 64 GB card now.
Good luck.

The ultimate solution !!!!!!!!!!!!!!!!
First u have to use an external card reader coz 99% of the problem is that i mean do not use ur laptop card reader but use a multicards reader coz laptops card reader r not designed for micro sd 64Go once u plug in ur micro Sd u should run a small software BOOTICE ( it's been attached to this post ) , u will see the real size right after in th picture 1
Fist u should update ur exFAT ( look to the attached files)
after that follow the steps on pic 2 , 3 , 4 ...the idea is to reformat ur card with single partition with exFAT and not FAT32 the exFat is an update given with microsoft it's been attached also.
Remember the prob comes from ur card reader and always use an external cards reader like the one used to format ur sdcard ....if u have any other question am here
warm regards

Hi,
Thanks for your idea, but i'm trying to get my SD as FAT32, but i'm having trouble seeing the full card. Is there anything you can suggest? My card is showing up as 27GB when formatted as exfat, it's 59GB (64GB)
My aim is to use an AOSP rom and i am unable to use the exfat file system.
Any help would be greatly appreciated.
Thanks.

[Q] 64GB SDXC card not working

I have an AT&T SGH-i747, I ordered a class 10 64GB SDXC card, when I put it in my phone it says "preparing sd card", then immediately says "it is now safe to remove your sd card". After several attempts to format the card (FAT, FAT32, exFAT and NTFS, which my computer does recognize) it started to tell me that my card was removed and to please insert another one once I insert it. There has never been an option to format the card in the storage section of settings, only to mount it, which yilded this result "prepating sd card" then immediately said "it is now safe to remove your sd card". I have serched through posts on this site and others, they all work under the premise that the card is no good and to exchange it, but my computer reads it just fine, so the card an't be bad, or they say that it comes formatted with exFAT which certain ROMs can't read, but I formatted it to FAT32 with no results. I am running Ariel ROM 2.07 with Ktoonzes Kernel. Any assistance you could provide would be GREATLY appreciated

Have you tried verifying the card's indicated space and speed? If you received a faulty or fake one, files would rewrite over and over again on something like 1gb of data (causing some files to not be readable). As asked above, where did you get the card from?
Sent from my SGH-I747M using xda premium

If you have e a custom kernel I.e faux, chances are it doesn't support exFAT.. In fact.. Most winxp computers don't either...
Assuming ur card is legit you need to get an adaptor and put it in a computer and format it to FAT.
I had the same problem with my sandisk 64 gb class 10.
I'd you look at my posts you will find step by step instructions on software I used etc.. Can't find it now on my phone.
Once you format it to FAT, it will work just fine. Assuming of course the card isn't defective

updates
I got the card from some Amazon vendor, the first one didn't work at all, returned it and bought from a different Amazon vendor. Poped it in the phone and it says "preparing sd card" then immediately "it is now safe to remove your sd card". In storage settings I have the option to mount the card, but I just get those two messages again. Formatted to FAT32 because I saw exFAT was propriety from MS with the same results, I used minitools partition manager I believe it's called. My computer was able to read and write to the disk until I allowed Windows to reformat it to ntfs, which took hours to reach 25 percent so I force canceled the format and pulled the card. From that point forward minitools said it was a bad disk and Windows froze when it would try to read it. I am using a Windows Vista computer which does not give me the option to format the disk to FAT32, only exFAT and NTFS. I am running Ariel 2.07 ICS with KToonzes kernel. I have a rooted stock nand backup or am willing to change ROM's if it has something to do with that, can't test that though as I've already returned the card. I also would rather not spend $100+, I'd rather just get a 32GB for $20. Thanks for all your help so far, I hope this helps you help me.

It appears to me that when you forced cancel, your 64GB micro usb got corrupted (which should not have happened, but did) that's why your Windows cannot read it. May be some one with a Win7 machine can reformat it for you. It could be something real simple like the MBR string on your card.

If it is taking hours to format NTFS then there is still something wrong with your new card as well

I guess I just got two bad cards then, or maybe the mini tools is to blame... guess I'll try it one more time. Thanks everyone.

I formatted my Sandisk 64GB MicroSDXC card to FAT32 (64k cluster size) with GUIFormat ( http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm). Even after that, it took some finagling to get it to work. I think I had to clear dalvik and also clear cache and data for the media related system apps... after that and a couple reboots (to force a media scan), it worked fine since. Make sure to allow enough time between reboots to allow media scan to complete (around 15 mins should be plenty), otherwise the media data may get out of whack again. Keep in mind that if you format your card correct BEFORE flashing your ROM, you probably won't have to jump through hoops to get your media data corrected.

But the problem repeat.

Card is bad. I had same problem after flashing a custom kernel once. The card is still sitting on my nightstand, taunting me. I don't know what did it, but at some point during the flash the card was fried.

Flashing a rom / kernel / package wouldn't fry the external sd card. Most likely the sd card is corrupt. I'd try formatting it again using windows, or linux, if available, fat32 format. if the sd card continues to show 'unexpectedly removed,' then the card itself is damaged and will need replacement.

Well, all I know is it worked perfectly fine until I flashed that kernel. When I rebooted from recovery, the card began throwing that same error. I tried several things, to no avail. The only time I've physically handled the cars was putting git in the phone 2 months prior. I tried formatting the card from my phone, and I've tried using an SD adapter & formatting from a PC (tried multiple adapters & multiple PC's) - none of them worked. Card is totally "bricked."

Well i try anything , 32fat format and some "health" program to sd cards
I dont know what is the problem.
Now the card is working but there is this message "sd card unexpectedly removed"
Sometimes it just wont load the files in sd external SD .
ill check the card with another phone and update.

This is really bumming me out. Just started experiencing this problem this morning.
I flashed FreeG 2.0 and it suddenly disappeared. Couldn't restore nandroid cuz all my nandroids are on my ext sd. But then out of nowhere, it re-mounted. So I was able to restore my cm10 nandroid. But now it's gone again.
Not sure if it's a problem with the sd card or S3. It's a fairly new Sansdisk 32G class 4.

HAHAHAHAHAHA Love it!

Had the same issue with my S3.
Turned out that the SD card was dying, this caused it to be unmounted by itself and then mounted again (sometimes showing notification “sd card removed unexpectedly”), hence triggering the media scanning process.
I created an application to monitor how many times the SD card was removed, and turned out to be unmounted every ~3 mins!!!
I then bought a new Transcend 32GB Class 10 card, and until now, this never happens, no reports from the application whatsoever, and no media process eating my battery.
I just published this app in the play store now, this is the link:

No. Wrong kind of memory. An SD card is not and never will be RAM.
I like to break stuff!

Storage, what its designed for. Its no different than partitioning your hard drive in your computer. It just splits the storage volume up. Older phones with less internal app storage people would partition their cards to use a2sd and gain extra app space thats it nothing else flash memory is like rom(random operating memory) a space for storage and containing filesystems. RAM (random access memory) is the space applications are executed in, it has a much higher read/write speed allowing the application to function without lag. You could put a swap space on sd but it still isn't RAM it will only be utilized by idle applications to hold them open while they are dormant. Android is already efficient in killing open apps to free RAM when needed and swap doesn't really work the same way it does on a pc. 9/10 times andorid kills the app instead of utilizing the swap space.

I think you need to read up on what ram is. Ext3/4 are filesystems and have nothing to do with ram unless youre using a ramdisk.

I think what you are talking about is swap. Which this phone has more than enough RAM that swap is not needed. Swap partitions kill SD cards anyways.

I don't know if I really wrong, but it's the proof. Here's the step-by-step how that man explain to increase the RAM using micro SD.
*)It's originally in Indonesian Language, but I translate it to English..
First Version:
1. first backup the data on your SD Card. because the SD Card will be on Delete and Format Partition.
2. Download Software for making partition, you can use the Mini Tool Partition Wizard or EASEUS Partition Master
http://www.partitionwizard.com/free-partition-manager.html
3. Install MiniTools on PC
4. Connect your phone to PC
5. Delete partiton SD Card and then click Create Partition
6. Because I just 2GB SD Card so I only make 2 pieces patition. First Partition Using Ext3 format. Partition for linux at 500Mb. Used to install / move apps from phone memory to SD Card
7. The second partition the rest of the first partition, the FAT32 format. Used to store data such as office, mp3, videos etc..
8. If the SD Card Has a fairly large you can make a 3rd partition Swap format. Swap partitions are used to support the work of RAM. and a swap partition usually made ​​of 2 times the RAM.
10. When finished click APPLY on the top left corner to execute the partition that has been created.
Second version:
Material that you need:
1. dtapp signed
2. A2SDGUI
3. Have already partitioned sdcard
The steps:
1. move the material to the sd card
2. Enter to recovery, choose mount storage and change to:
_unmount / caches
_mount / data
_unmount / system
_unmount / sdcard
_unmount / sd-ext
3. If you done, back to start menu and install dtapps2sd cwm-2.7.5.3-beta04-signed.zip who already downloaded earlier. . finished and reboot the system.
4. Then install A2SDGUI open a2sdgui zipalign on boot and set swappiness 60-65. Then move to Dalvik tab, select the Dalvik cache on sd ext, click move. allow it to reboot. See Picture.

5. Wait wait until the reboot is complete.
6. After your phone ready, enter terminal emulator type this command.

_a2sd datasd
let it reboot

And this the result.
Third version:

even if you could, tricking the OS to use sd as ram would be awful.

its impossible to use an sd card as RAM. anything that tells you otherwise is lying. the only way to get more ram is to buy a better phone.
