[Q] Can't read/write SD card - Android Q&A, Help & Troubleshooting

Hi,
I did a backup using Titanium Backup and Go Backup and after wiping my Motorola Defy, tried to restore apps, contacts etc.
The problems I encountered were:
1) Go Backup can't recognize backup directory on SD card for some reason.
2) Can't move apps to SD. An error occurs: "Move Application: Failed to move application. There is not enough storage left." Needless to say, I have more than enough storage.
This is was I encountered by far, although I believe these are just a small part of the symptoms for a single problem.
Maybe its because there are no permissions, or moving apps is impossible because of an existing app files on the SD card.
Does anyone know what is the actual cause for this?
Or is there a tool to fix the permissions on the Defy?
Thanks ahead!

See if any of your other partitions are full or close to full.

I have no partitions on my SD card

No, I mean the internal memory of the device.

Does it has to do with the moving app to the SD card?
And it seems I do have a little space for apps, but how should I check it anyway?

The easiest way is to run Link2SD -> menu -> Storage Info
This will show all the mounted partitions, and space used/free.

Internal: 103mb used, 25mb free
SD: 8.71gb used, 6.12gb free
SD 2nd: not found
System: 178mb used, 148mb free
Cache: 16.29mb used, 177mb free

No idea?
I tried that:
1) Deleted the GO Backup directory
2) Removed the app
3) Re-installed the app
4) Copied back the backup from my PC
I could then see use the backup, but I still can't move apps to SD
Something must be jamming it
Can it be something with the mounts?

I haven't used Go Backup, so I have no experience with it, but it does seem that it's somehow involved/responsible. I noticed they have an update as of yesterday, so you can see if it makes any difference.
Have you tried putting your SD card into your computer? Does it function normally? Can you run a disk check on the card from your computer?

The problem is not with GoBackup, as it works now.
The problem must be with something jamming access to the SD card.
I tried to run a check from my PC and I get "No problems found"
And now, for some reason the phone activity crashes after I terminate a call

Well, all the applications I installed where installed using Titanium Backup.
While trying to install from Play Store, the device crashes.
It uses CM 7.2.
So it might be a permission problem in the device itself.

[Q] Apps required to be in phone memory.

I have rooted my optimus one.
just wanna know which are d apps that are neCessary to remain in the phone memory.

Widgets should remain in the phone memory. Everything else that doesn't run frequently should go to the SD card

unable to move maps n youtube.
stil woried abt lockscreen n launchers.
Are you using the stock ROM? Apps that are in /system/app cannot be moved to the SD. If you installed it via downloading/installing from the market or somewhere else, you can move it.
Everything that feels like it should be launched no matter what or those that need to be started quickly on boot, keep it on the phone memory.

Yeah. m on stock.
did move sum apps to sd via app 2 sd enabler.
Cmon guys I thougjt it was safe to move all sh#t to sd
It's safe. It's just that apps that need to be started on boot must be there as soon as it can. Read and write speeds on the SD card is much slower than on the phone memory.
Well he didnt ask for fast boot
It's not about fast booting It's about getting the things you need as fast as you can. For example, I need a widget to load as fast as it can since it has to be there as soon as the phone boots. That was my point
Everything that you don't use everyday move to SDcard (if possible). If you move favourite apps to SD and you acces them all day long you will shorten the SDcard's life.
I have void with a2sd enabled. So all user applications are on sd. Can I use titanium backup to move some apps to internal memory?

I used Titanium to move a lot of stuff over to the SD from Internal... Stuff in the /system directory doesn't affect your phone's "Internal Storage Space" as reported in the Settings menu since /data and /system are separate partitions. Apart from /system apps, the only thing that I would want to move to the SD that it couldn't move was the PayPal App from the app-private location. Going into ADB wouldn't allow me to do it either.
Titanium also allowed me to uninstall a bunch of the **** that came installed like game demos. This did not free up additional storage space, with the exception of what it removed from Dalvik-Cache. Which, btw is going to be your biggest issue... Some ROM's allow you to move this to the /cache partition, but this is a relatively small partition (~56MB) on this phone and my Dalvik-Cache currently takes up ~90MB.
Pls reply here guys.

I use app 2 sd to move everything I dont need frequently on SD, than just long press on those program from app 2 sd and Open them.

I used Titanium again and used it to incorporate the updated GApps into the ROM. I knew that I had about 56MB free on the system partition. Putting Gmail, Maps, Street view, Market and anything else that I could find freed 30MB on the data partition.

mnt/sd versus mnt/sd/ext_sd

What's the difference? Ever since coming to the rezound everything has been saving to mnt/sd and all of my old stuff is on mnt/sd/ext_sd. therefore my apps can't restore backups. This is super annoying. What can I do to remedy this problem? Thank you.
Sd is the internal and sd_ext is the external card.
Move from internal to external and set your apps to use external.
Setting apps to use external only works if the app itself allows it, correct?

That is correct
Yeah I've been having this problem too. Even though I copied my backups from the external to internal storage, the apps don't see the backup files. I even changed the location for the some of the apps to look at for the backup files for restoring and it still says no restore files found.

Apps in SD card not visible after factory reset of phone?

I was trying to root my HTC One V and i unlocked the bootlocker,however that resulted in factory reset of my phone.Whenever i installed an app on my phone i always moved it to sd card via settings-->apps.I assumed that once my phone restarts after factory reset it will read the apps in the sd card but it is not so.The phone does read songs,pictures and contacts stored on my sd card and the sd card does have the folder of each app but how do i install it from the sd card?

The stock android move-app-to-sd does not move all app data to the sd card and some data is left on the device on purpose.
I might be wrong (since I never researched this) but I think you cannot restore those apps.

Okay
But is it possible that if i install the same app again,it reads the application settings from the sd card?Like if i download and install a game,is it possible for the game to read my score from it's folder in the sd card?
If the app is storing this kind of information (settings etc.) on the sd-card as a separate file then I would say that it is very likely that it will be able to read that data.
But not all apps store that kind of information on the sd-card (security reasons etc.).
I am not sure what happens to the parts of the app itself that are still on the sd-card though (I am talking about the app itself). I guess that the app will not care about those if it is stored in the internal storage. Moving the app to the sd card will probably overwrite the data on the sd-card. If the app stores the settings etc. in one of its own files then it might be overwritten as well.
You might want to make a backup of those files, even if you can't use the information in the end. But if they are gone they are gone.
Some really crazy idea would be to download the app, move it to the sd-card and then overwrite the files on the sd with the ones from the backup.
If android has no verification or security methods for this and there was no update to the app there might be a small change that this will work.
But I guess that the chances to get all your settings and user data back are still very slim as those are possibly not stored there.
But if you have the backup and some xda user swings by with a good idea (or more knowledge that me) you can still try that.

[Q] clearing internal storage

1st issue is wheni look at sd card while connected to my desktop or from a file explorer, it says my total space is only 10 gb. 2nd issue is im deleting things to free space, but i dont seem to be gaining any space. i deleted a bunch of pictures. i used sd maid to clean up some things, but im not gaining space. why is this?

Take out your ext-sdcard. reboot phone and in esfile explorer set root permissions for r/w to w. Click the menu button (hard button) and select sd card analyst. This will let file explorer go all the way thru root and find out what file is causing the size issue and tell you where it is. Voila. Hope this helps.
It was twrp using over 4gb. I deleted it. I keep my backups on ext SD anyways. At least now I do.

Crap. P.S. If you make backups , they are usually 3.8gb. (sorry, forgot to mention that.) Guess i should add that to the FAQ's.
It was a stock ROM backup from when I first rooted. I have a newer backup of it on ext SD

[Q] the whole writing to SD card thing. annoying now.

i've tried fixes via this site (including one from xposed. it's not a problem for most things but titanium backup just won't do it. the folder over a few weeks seems to go read only (checked via root explorer - can't give r/w rights) and just fails saying insufficient storage space.
i have to pull the card (can't mount as proper USB anymore - shame), create a new folder and move the content over. this works for a while but then i get the same again. something makes the folder read only.
other apps are able to write/delete etc to my mSD so the fix must work so what the hell is TB doing?
i'm on 4.4.2 (this rom from a while back)
any advice (bar flashing to 444? - might do that next w/e anyway)

Are you trying to get apps to store on your Micro SD card and not internal?
On the play store, if your phone is rooted there's a fix so you can write to the card. If you wanna save space I suggest downloading folder mount.

I would advise you to backup the contents of your external card. Then format the card by inserting it into the phone. & of course USING the phone to format it.
I had the same problem. I did this & touchwood, no problems so far. Hopefully it should work for you.

Lol what are you talking about? I don't have issues with my card I think you meant to quote the other guy....
Anyways I think he's talking about the write issue in kitkat. Download SD card fix, you only need to run it once.
Oops! Big faux paus indeed! That is correct mate.
I will do a check on the SD Card fix. Seems interesting...
formatted the SD card and copied all back on - same thing happens. it's only an issue in TB for some reason. works for a while then stop.
tried the sd card fix too (must work i presume otherwise other apps would have probs too).
i'm not trying to install apps to the mSD (although would love if google brought that back).
Im using liquidsmooth rom and gdkernel. Still cant write into the sdcard. I tried all the app fixes and xposed..
Pls help.. .

Download that, you must have a rooted phone. I've had no issues with this app, only run it once. Upon success, remove it, done.
Yeah. Ive already tried that app and other. And also the xposed apps. Still didnt work. cant delete files and sd card.
