app2sd question - myTouch 4G Q&A, Help & Troubleshooting

So where does the data go when you move an app to the sd card?
I moved them once and then did a full wipe.
I had roughly ~5.xx gb left on sd card. Now after moving them again, im down to ~4.6
How can I tell if I have doubled up the data and am taking up excess space?
Thanks.

Nothing at all?

Has anyone noticed? SD memory card full to early?

So i have to standard 16gb sd card, and i know that about 2 gigs are full just from the programs, and reservation the phone puts on it, but so far i have 10 out of the 14 Gigabytes stored, and it says memory full... only 10 out of the 14 are full, and yet it wont let me put anything on the phone or even take pictures because the memory is apparently "full". does this happen to anyone else?
its full because you are using it. I bet you move all kind of cache onto your sd card and install all kinds of programs in there too.
But the card still says i have 4 gb left of OPEN UNUSED SPACE!

app2sd self destruct

My Eris has been running very smoothly for several weeks with ELB 2.7 with JIT enabled and most of my apps relocated to the SD card. But a few days ago, I started experiencing crashes when waking up the phone or answering a call, and then last night I started getting FCs anytime I tried to launch an app located on the SD card.
The FAT partition works fine, and the EXT partition appears intact when I mount it, but nothing located there will launch.
I've resolved the issue (sort of) by reinstalling the apps I need on my phone, and switching off App2SD, but now I'm wondering what the next step should be. Does this indicate that my SD is dying, or should I try repartitioning the card -- either to eliminate the EXT partition entirely or to recreate it?
just try reformatting the card...if you start experiencing it again...then your card is most likely dying... sorry...
Even if you got your Eris on the first day it came out, your card shouldn't be close to "dying" yet. Maybe it was defective to begin with. I'd bet willing to be its not the card. I know a2sd is harder on it, but I just doubt it killed it already.
Copy your apps to PC, reformat SD Card, Copy apps back, and see what happens.
Please report back, I'd be interested to see what happened.
Apps2SD isn't recommended by a lot of the devs for a reason. It causes unnecessary wear on the SD card. SD cards have a limited life span of around 100k cycles. When you access a program on the SD card it doesn't just make 1 cycle (read/write), it makes many during the usage of the program. 100k for picture taking and other standard use is quite a bit, but when an app is accessing the SD card constantly while running 100k is reached very quickly.
I'm going to take a guess and say your card is dying for reasons stated above. Try reformatting as recommended, if that doesn't work, replace the card.
The only time this would be a concern is if you moved dalvik-cache to the SD card (as that is constantly updated). When you put an application on the SD card, the data related to the card is stored in /data/data, which is not moved to the SD card (this is why internal storage continues to decrease after you move apps and dalvik-cache to the SD card).
Also, it's 100,000 cycles per block of memory. Most SD cards have wear-leveling technology that helps with this issue, so it will take a while before the card becomes bad (if it is a good quality card).
I would say he has a failing card. It happens once in a while.

yeah u gotta be very careful with app2sd
I followed the advice of several people and repartitioned reformatted my sd card. I decided to go without app2sd for awhile so I just did a single fat partition. So far so good...everything is working again.

[Q] Galaxy S4 Storage Issue,

So i Got an S4. I rooted it and im running stock 4.2.2 XXUBMEA firmware. With the new update, i can move apps to the SD card, but App data is still internal. you cannot move app data. About 7gb of my internal memory is already taken up by android which leaves me with around 9.23gb left. after installing all my necessary apps, i have left about 7.3gb internal storage left. The problem is here. Most HD games these days have Data files around 1gb. for example, games like Asphalt 7, Batman and GTA Vice City. they all have sd data of around 1gb. And as you know, on the s4, unfortunately, you can only put Sd data on the internal storage and you cannot put it in the micro SD card. So, in order to play these HD games, i have to use my internal memory. By doing this, i wont have much memory left and will probably run out of memory after 3-5 HD games. What do you think is the best solution for this? How do i play a lot of HD games on my device? After all, I paid a lot for this phone. I hope i did not waste my money. Remember i am rooted. Is there anything i can do?
Thanks
Help will be much appreciated.
Since you have root try Folder Mount. It transfers game data to sd card and mounts it to internal sd. Free version let's you add 3 apps paid version is unlimited. It's worth ebery penny trust me

[Q] External SD Card/Storage Issues

Hi all i'm fairly new to the xda forums but I just recently had a strange occurrence happen on my S4 that I was hoping someone could help me resolve or at the very least explain it to me.
Ok well I have the sprint galaxy s4 with a 32 gb external SD card if i'm not mistaken. Well I enjoy downloading videos and files to my phone instead of using the internet to watch them because I get bad service where I work. So it's much more convenient to just download them beforehand and watch with no buffering.
Well after awhile of doing this I downloaded androzip file manager so i could rearrange my files so I knew exactly what was on my phone. Well as of yesterday my total space on my device was 16GB and my available space was around 7.2gb. My SD card as i said was about 32 or so and my available space was around 14 to 15GB.
Well I went to try to download a 4 and a half long video in high quality and it all of a sudden said that my memory was full. As far as i knw this video was about 4 gb or so...which should have fit on my device or SD card. Well after finding this unfinished download then deleting it I decided to try to free up some space on my phone to hopefully have more room. Well I googled it and alot of people said an app called SHREDroid was the way to go and that it would completely erase files that I had previously deleted so it wouldnt take up unnecessary space on my phone. Well i used it on my internal and external memory and now my storage looks really funny. My available space on my device is somewhat normal at 7.82 GB. But my SD card is just strange. I havent downloaded anything else and it went from that 14 or 15 GB down to 2.82GB.
How in the world could this have happened. I have nothing new in my external card as far as i know. Can anyone please help me with this?
Sorry for the long post i just wanted to be clear and concise. Please feel free to tell me any details i may have left out
Thanks everyone!
Lots of reports of bad SD cards, so that's a real possibility here.
But what I'd do is backup everything on the SD card to a PC. Then I'd format the SD card (Settings>More>Storage - Scroll to the bottom). Then copy everything back onto the card from the PC and see if that fixes it.
Is your sd card formatted to FAT 32?

SD card as Internal? Is it really a good thing to do??

Even though I got 32gb internal and having Samsung 32gb sd card, I selected the option to make 'Sd as Internal' (I thought that in future I'm gonna install huge games and there would be internal memory lack).
But after doing this I can't see my internal Storage and same time Im sensing that my 32gb internal will be not fully used. And I know(as I have some android knowledge) apps in internal(system) will run smoothly than in sd card. And class 10 sd card is good for media not for system contact. Now I have to dump my data(songs&movies) in the same storage where system treating it as 'Internal'. So I may not put huge data in my sd card at where as my internal will be some what unused much.
If you have 32gb internal(this is almost enough to run apps without lags) and 32gb sd(more songs&stuff) I suggest you "Don't make your Sd as Internal".
This is my opinion. What's yours? Am I correct or You want to change my mind throwing some light?
yeah I did the same thing!! 32 gb is enough for apps

I agree. With Android 6 the 'external' storage (microsd card) can no longer be used for moving apps to. It's data storage only. When you have a phone with limited memory (say 8 GB) and want more to store your apps, you can use the SD as internal. This will format (and encrypt?) the SD and replace the internal storage.
As SD is generally slower, I would advice against it. When in a couple of years we're at Android Z and the 32 GB is indeed a bit small, you can opt to go to the 128 GB SD, but until then I would use it for data only. (I have my Titanium and TWRP backups on it, next to some media, nothing more)
32 GB (23~25 usable) is more than enough for apps and few games..and I don't recommend to use SD card as internal..unless your device has only 8gb memory then use a high end SD card..such as Samsung evo+ or pro. (Correct me if I am wrong but I think Google introduced this feature for their low end Android one phones..)
Don't do it , formatting sd card as internal will reduce its performance and also it will be encrypted. So you can't use the data with in it without the same phone you have formated it with. Since g4 plus have 32 gb internal it's totally unnecessary
