[Q] Is it the SD card at fault?

hi all,
thought i would ask here as my questions in the rom specific forum are getting swamped by every asking for the dev to install specific programmes or people asking wht OJ death is..
im just trying to narrow down if my SD card is faulty, the rom is causing the issues or i have or am doing things wrong.
on random occasions i have lost apps, photos and other info from my SD card.
the first time it happed i did a nandriod backup prior to a rom update.
right after the nandriod back up my phone booted up and every photo i had taken in the last 2 days were gone.
thankfully using Recuva data recovery program in windoiws i was able to find and restore the photos.
i then updated my rom the Open desire rom, the one that enabled the OTA menu system. as far as i know there were no other things changed in the initial update.
after rebooting all my sd card data was wiped.
BUT.... some of the apps on the sd card were still there and some were gone, as well as apps on the phone, some were gone some was not.

You're not alone... I too have a similar issue, with an un-branded, un-rooted Desire. The first think I noticed was a duplicate "Backgrounds" folder appearing in the 3D Gallery - which in itself is odd, because the standard Gallery app only shows it once.
Weirdly in one version of the folder I have a few less images than the other, but they're otherwise all duplicates and can only be found in one visible "Backgrounds" directory on my SD card. It's not just the Gallery app aither - some others (like Wall Switch) also see two "Backgrounds" folders.
Then I noticed a number of images had mysteriously disappeared from another folder - in both Gallery apps. The only app that's crashed is Wall Switch - which is probably related, as it's looking for images in that "Backgrounds" folder. It works fine most of the time though.
If any images have gone missing, I should be able to get them back as I recently upgraded to a 32GB card and copied all my files across before doing so. However, I'm more concerned that there's a problem with the new card. (Which, for the record, was not a cheap one from eBay.)
As such, I'll be spending some time this weekend testing the new card to see if I can identify any issues... but I too have a couple of questions in that regard:
i) Is there any benefit in formatting the card in the phone before use? (It came pre-formatted so I first checked it for errors in Windows first, then just started using it.) I realise before Froyo the phone could not format such big cards, but I think that may have been resolved now.
ii) What's the best way to verify the integrity of the card? (e.g. Will error checking via Windows - XP in my case - suffice?)
EDIT: I took the card out and copied the files (minus my MP3 library) back to the 4GB card that came with the phone. When I ran with this card the duplicate directory disappeared. CHKDSK found no problems on the 32GB card, but I reformatted it in the phone anyway and then copied everything back to it and all is now fine. I'm assuming the phone did a "Quick Format" rather than a full one, as it only took a few seconds. I'm not too worried about the missing image files as these may have been inadvertently deleted anyway. Fingers crossed the problem is behind me now, but I'll keep an eye on it.

I am having similar issues, it's almost like the SD card is not fully loaded, and tried to load but can't. Things are missing, and then they are there. I am using a new 16GB over the original 8GB.
I am rooted though, am I able to do a format of the SD card?
Also when I choose to make it work as disc drive, nothing happens, does not show up on system.

i had the same issue when i first rooted my phone i was able to put the card in an old HTC and it showed up as a drive in USB mode and i was able to run a file recovery tool to extract the data
then re format and copy the data back to it..
but the current issue is just random and strange...
stuff just seems to disapear as far as the phone is concerned ...
as i have already mentioned i had stuff vanish after running nandroid back up..

So for me it seems it happens shortly after bootup. Yes I give it enough time.
But once I open the all programs area, I see it load all of the icons. Maybe some issue with it not loading untill I open that area up.
Also, most of issues seems to be coming from the App Organizer Application, it's updated often so hopefully my issues will go away.
*As I play around with things it seems almost all my issues are related to the program. Even the issue with it not showing up on my computer when connected through USB. It does show up, just takes awhile, and once it does my Apps Organizer icons flash. So related.

[Q] Gallery3D raises the dead...

I searched as best I could, but couldn't find a match to this particular issue.
I do have a rather weird issue with Gallery3D, that I've noticed after switching to OpenDesire, in 4.0.10 and 4.0.15.
Until recently I have been using various Sense based ROMs, where photos taken with the phone are stored in DCIM/100MEDIA and I always just used HTC's gallery app.
Now I'm on OpenDesire 4.0.15, which stores phone photos in DCIM/Camera, and uses Gallery3D to display them.
The thing is, when I try to display photos from DCIM/100MEDIA, taken earlier on various sense ROMs, Gallery3D shows some completely random photos instead. The thumbnails in 100MEDIA display correctly, but when I tap any thumbnail, it expands to the grainy fullscreen version, and is then replaced with a sharp and refined version of *another* picture.
It shows photos that I have taken with this same handset, but imported to my computer and deleted from the phone long ago. That is, photos that aren't even *on* the SD card anymore.
I have tried the following:
1. settings > apps > manage > Gallery3D > force stop + wipe data and settings
reboot
no luck
2. rename 100MEDIA to something else.
repeat 1.
no luck
3. Create new folder DCIM/Test
Copy files from DCIM/100MEDIA to DCIM/Test
The copies in DCIM/Test work well.
Hm.
4. factory reset, wipe cache + dalvik
reflash OpenDesire (4.0.15)
no luck
5. Made a flashable zip with most recent Gallery3D.apk from this thread and flashed it over the one included in OpenDesire 4.0.15
No luck (yes the update succeded, different file size )
Ok, fine, so I kind of solved the problem in attempt number 3, right? Well, yeah, except that I'm uncomfortable about my phone magically raising photos from the dead that I've deleted long ago.
Have you guys got any ideas or input?

Well, your deleted pictures aren't exactly "dead", they just aren't in the master file table of your SD once you hit delete, but they can definetly read. But to avoid going offtopic, you can simply back up your files, format the SD card and restore the files. Everything should be ok.
As to why this happened, it's possible that your Master File Table got corrupted somehow (or Android's MediaManager isn't reading it correctly). But I can't really say much since it's difficult to tell what the real cause is (perhaps you didn't "safely remove"?).
Either way, reformatting should help. And keep using Gallery3D from that post, it's one of the best around

Reason
Even i experienced the same issue,,but couldn't find the solution,,,,but i figured out why it is happening..!!
My gallery 3d app was showing the images i took long back which are no more in the SDcard..!!!how can it be possible..??
The reason is,,
>When we delete the file in the sd card,,the operating system will just mark that that memory location with some special character ,,in fact the data will appears to be deleted but truly i won't ...!!
>when we add new files to the file system that space will be overwritten ,,,by the new file...!!
>So in our case the file which appears as the thumbnail is in exact same memory lactation as the old deleted image....so the thumbnails will be stored in different location as the cache,,,,,
>this is the reason why it show the thumbnail but when we click on that,,, it shows the original data resides there....!!
> its just a bug in the Gallery app
>And it will happen only when we delete the files inside the gallery app...
>Next time try to delete the files in Some file managers like Astro

Apps on SD disappeared???

Hi everyone,
In panic mode right now...
I downloaded an app that helps you find all your apps that can be moved to the sd card. So it found 150 or so. After an hour of manually moving each one, I had over 400mb of free internal space and only like 40 apps left on the main phone storage. Awesome... but then this morning I noticed that things were running real slow... so I rebooted my phone. When it came back up I noticed some of my home screen shortcuts had become generic android icons. I went to my launcher & lots of apps were missing. I have a LOT of apps so I can't quite confirm yet whether its all the apps I moved to sd but it seems that way.
When I go to the market I see apps that I had yesterday as not installed. I have astro but I'm not quite sure what folder to look in to see if the apps are all still there, just not being seen by the android system maybe?
I've been driving all morning so I haven't gotten to research this much yet. Just rebooted a couple times hoping to fix it but no luck yet.
Any help is majorly appreciated. As soon as I'm at a computer ill be working on this all day. Freakin disaster!

update to my question
so now that i'm in to work i can mess with this... quick update...
when i go to manage applications and go to "on SD card" i get a big list of apps that have the names like "cn.miren.browser" instead of Miren Browser and "com.alphonso.pulse" instead of Pulse which is kinda normal except usually they then refresh with the regular name and the size listed underneath. well it's been sitting here for 5 minutes now and hasn't change and it still says "Computing..." under each one and instead of the normal icons, its sort of a grayed out generic Android icon with an SD in the bottom right corner of the icon.
so clearly it still knows that these apps are there. it just maybe can't access them? i dont know. could it be the sd card? this is the original 8gb sd card that came with the g2...
any thoughts?

???
so i found out that the sd card had some errors in the file system. so i let windows fix the errors. no help (although my phone boots WAAAAAYYYYYY faster now).
so then i found that i have an extra 8gb microsd laying around (which also happened to be a better, class 6 one too). so i cleared it off and copied over alllll the files to it. booted up. STILL NO GO.
anyone have any ideas here? i'm really running out of ideas here.
when i boot, everything runs great, but all my apps that are installed to sd are gone. also it never says "preparing sd card" in the status bar when booting. then if i go to manage applications it never finishes "computing" the size of apps. if i go to "on sd" it shows all my apps, but says computing, and i can't access them, uninstall them, move them, etc. i'm totally out of ideas here and i really don't want to have to do a system restore.
anyone?

think im having the same problem . has ur market gone too?

fix?
ok so i ended up getting mine fixed using these steps that someone from a company that makes an apps2sd app sent me... the only difference i had to do was since my phone also wouldn't recognize my pc, i had to pop the sd card into my pc directly to delete the .android_secure folder... i don't want to mess up your phone or anything so make sure to read around a bit more before trying this, but this is what worked for me. after i started adding all my apps back one by one i've been fine ever since.:
"I guess the problem is ".android_secure" is not recognized by Android.
Would you try the following steps (I am not sure if it works)?
1. mount phone with PC
2. backup all files under .android_secure
3. delete .android_secure directory
4. unmount
5. try to move an app (any app) to SD card (it forces Android to
create .android_secure on SD)
6. mount phone with PC
7. restore all backuped .android_secure/* files to .android_secure
8. unmount => check if it recognized the apps that you moved to the SD card"

Camera won't save pictures, can't dl whatsapp-images

Hey Guys,
I'm having a problem since i first rooted my Nexus GSM: When using the camera, the clicking sound appears, but there is no new thumb in the corner and no picture saved in the DCIM/Camera folder. If I'm trying to do a video, the app crashes.
If somebody sends me a picture in Whatsapp, I see the litte thumb, but if i click it, nothing happens (and of course - no picture is saved on the phone).
I check the permessions for the camera and the DCIM-folder and I let the RecoveryMod fix all permissions. Do you have any idea what could have gone wrong?
First I installed Revolution HD ROM, today I did a reset and installed AOKP ROM. Problem stays the same.
I hope you can help me!
EDIT: Checked data & media, too.. everything is rwxrwx--x

Ok, I fixed it.
If anybodye else got this problem: I simply deleted the DCIM & WhatsApp-Folder.
Don't know why i didn't try that before -.-
Sorry guys

permissions the cause
hi, i had the same problem. PERMISSIONS SEEM TO BE THE ISSUE....
I backed up and restored my memory with the tool kit.
Under "BACK UP OPTIONS" i selected "3. backup you Internal Storage [virtual SD Card]"
The only way i have been able to get around it is by changing the name of the dcim folder as i was unable to delete it.
note: i have also had various other problems with other apps. these apps had folders that were restored via the toolkit. in some cases all i had to do was rename the permission locked application folders. in other cases i had to rename their folder and create a new one with the original naming and sub folders

[Q] Unexplained Consumed Memory

I bought this Samsung Galaxy Tab 3 SM-T210R for my mom its currently running kitkat 4.4.2 non rooted which I am about to fix here soon.
The problem is my mom hardly does anything on this facebook some books recipes and maybe 1 or 2 games and her church stuff and for some ungodly reason it keeps telling her she has low memory around 775mb left and it wont install anything else.
I put a 16gig sd in it for her and moved everything possible over to the SD cleared all the cache from all apps and have gone to the extent of restoring it to factory and it still keeps doing the same thing.
My only thoughts are root it with custom recovery and wipe it that way and reinstall the firmware but that is a extreme I would only do in a worst case scenario.
If anyone has any idea's I would appreciate it this isnt my first rodeo with android devices I am not a complete novice I have rooted my phones in the past including my current galaxy s4 so I am open for any and all ideas.
Thanks,
West

Yea I am aware of that part my problem is I keep wiping the tablet and restoring to factory and within a couple hours it tells me it has full memory or low storage space again.
I went to the extent of deleting the non needed folders such as downloads images dcim etc and letting the system remake them assuming they were the culprits I also went into the Android\Obb
and also Android\Data and cleaned out the stuff that did not need to be there on my last factory restore.
And No matter what I do upon resetting back to factory the space gets consumed within a couple hours and that's only just browsing the web and clearing the cache when done.

hi, if you have a large amount of pictures/video, it may be gallery
generating/regenerating thumbnails in /sdcard/DCIM/.thumbnails.
Check the size of that directory, if that's the case delete the directory and replace it
with a dummy file named .thumbnails an set it's permissions to read-only
i ask because if your moms got hymns etc. that are actually in an image format instead of text
those will have thumbnails, the same with some ebooks.
Replacing .thumbnails with a fake .thumbnails will only make gallery run a little slower.
Many apps do the same thing, generating images in hidden folders on your sdcard for caching ads etc.
