[Q] SD card keeps freezing phone

So I flashed my Captivate back to stock using Odin and then flashed Cognition. Everything seems to be working fine again except my phone locks up every time I try to access the SD card. It usually happens whenever I open gallery but also sometimes when I'm in a game or some other application. I can still access it fine through a computer and it doesn't look like I have any corrupted files but it just keeps on locking up my phone. I tried reflashing Cognition and that didn't help. I'm wondering if it's a problem with the SD card even though I've never had any problems before because I've done countless restarts and battery pulls today so it's possible something got corrupted. Any help would be greatly appreciated!

Does it have the standard directory where you store your photo/films?
or
Did you try to reformat (FAT32) it? Then take a few pictures (so it does create the stanard directory/~ies). Seems to me it's missing some..

I finally fixed it by going all the way back to stock and reflashing everything. I think it may have have had something to do with the overclocked version of Cognition I was running or perhaps a theme I installed. I was pretty sure it wasn't an issue with the SD card as nothing was corrupted and I could access it fine on my computer. Either way it works again now!

just as a future reference.. you should ALWAYS backup your SD card to your PC considering SD cards DO fail. I lost almost 4.5gb of info because my memcard was corrupted and I had to start collecting all over again (+ i lost something like 600megs of cell pics).

[Q]: Applications not loading from Storage Card

All of a sudden apps on storage card fail to load.
After a few reboots they reappear at random, but disappear again on reset.
Did not have that problem with stock, but after flashing Infused 1.14 (and on) the issue appears even with the (rooted) stock rom.
Any ideas?
I am trying to determine if I need to return and replace the phone before I lose the option.
Thank you in advance.

Answering the question by myself, in case others encounter the same issue.
The external card had something corrupted, and when the system was mounting it, all mess ensued.
Backed up all the data and reformatted.
System appears ok for now

I just had this same problem or at least something very similar to it. Initially I thought it was the 32GB SD card being too big since I read Android had a 16GB external card limit. But those posts were from a year ago and when I searched deeper I read that 32GB cards were being use without size problems now. There was one issue that seemed to affect some people and that was that android could have problems formatting a card that big and that's how I installed it in my Infuse initially- I let the Infuse format it, then popped in in my Macbook Pro (in OSX) to copy over the contents from the previous 8G card. I believe I have hidden files set to show, so I should be copying over everything- though, could this method of upgrading the card be a problem too?
It worked for a couple days, but last night during a reboot I tried to access the app tray and didn't know the card was still being scanned. It froze and I couldn't get past the secondary media scan after many tries. I didn't realize that apps were being automatically installed to the card.
Anyway, I was gonna return the card, but after reading your post, I'm thinking again about corruption due to poor formatting as the problem, so I'll try it again when I get home. Thanks for your post. I really want to be able to use this larger card so I'm keeping my fingers crossed this will solve the problem.
BTW, how did you format the card? I have Win7 x64Pro on my MBP as well if I need to use windows, but did you use FAT, FAT32, ExFat? I'm still a 'droid noob ;P. Thanks again!

[Q] Apps gone

Hi after having to switch my phone off, when I turned it on again it appears that all the apps I moved to the SD card are no longer there. I have just spent some time downloading them from the market again.
Question is why has this happened and how do I stop it from happening again
Thanks in advance

Solution
Hi Nexus.
I think you'll find that the apps still exist, they're just fragmented on the SD
card. This has happened to me plenty of times.
I've found it's only apps that are installed on the SD card and it's never
happened with apps on the phone's internal ROM.
A good way to check is to go into: Settings- Applications- Manage applications-
then tap the SD card tab. That list shows all of your apps installed on the SD
card. I found that when apps here got fragmented/corrupt they didn't show their
original app icon. Instead they showed the stock android app icon. This is a good
way to tell if the missing apps in question are still there but are just fragmented.
The way to solve this, the way that's worked for me, is to plug the phone into a
pc and mount the SD card as a disk. Then on the PC access the SD card via
explorer and right click- properties- tools- then click de-fragment.
This may take up to 30 mins as it's not as fast as a HDD.
From using this technique my apps have always returned and I can use them
with no problems again.
I've also noticed that this issue only happens if I restart or turn the phone off. I
don't understand what is corrupting the apps as the SD card is mounted
correctly and is the one supplied as standard.
I hope I've helped, and I guess this will save you from re-downloading all of your
apps again.
I'm happy to hear anyone's thoughts/suggestions onto why this is actually
happening in the first place too.
Cheers, Dms

Hi thanks so much for the answer. This has been bugging me for ages and even though I have been searching I have not had any joy solving it until your reply.
As you said it only seems to happen to apps on the sd card, and I would like to know why they are not "persistent" There must be a developer who understands the Android system who can explain why this happens and what you can do to make apps you have on your sd card permanent.
As you said it only happens to me when I re start my phone.
Thanks again for the answer

Hi. It's no problem. Yes I havn't seen anything about this issue being mentioned either.
I'd like to know what's causing it. Whether it's a hardware fault or something in the software.
It's a real pain having to hook it up to my pc to sort it out. Especially when I'm away from a pc, I can't use half of my apps.

[Q] Cannot delete or add to SD card

A few days ago, I tried taking some pictures with my Droid Charge and the pics would not save. I tried in the stock camera app and in CameraZoom EX. CameraZoom gave me an error message "failed to save photo to SD car (error code=2). I figured I was out of space.
My Titanium Backup scheduled backup did not run the next day. So, I assumed I was out of space.
I connected the phone to my PC and deleted some pics and music. WHen I was in WIndows explorer, it said I had about 2 GB free after doing all of this.
When playing music today, I noticed files that I had deleted before still present on the phone. I thought this was weird. I went back and checked and all the stuff I thought I deleted was still there.
I searched on the CameraZoom EX error code 2. It directed to remove and reinsert the card and reboot. I tried that. I have tried unmounting and then mounting with no success either.
My phone seems to be working fine, but I cannot delete or add anything to the microSD card (the original that came with the phone). It does not matter if I use my WIndows 7 laptop, desktop, or various file managers on the phone itself.
ANy idea what is going on?

To me, it sounds like the SD card is going bad. Not a common occurrence but it can happen. You're lucky you can still read from it... I would suggest getting a new SD card (Verizon might even give you a new one free) and copying your data to it before sectors start going bad. By the way, how did you manage to full up 32 gb?
Or I could be blowing this out of proportion and it's just a matter of write protection on the card.

Another option is to copy everything off the SD card, format it, and try to write everything back. Sometimes a format can joggle a bugged card.

It is mostly music that I have on there. I am not sure how write protection would have gotten on the microSD card or how I would remove it. It does not have a physical togge like an SD card does.
I think I may have to try re-formatting. Ugh.

Corrupted SD card. Call VZW and be nice on the phone, explain the situation, hopefully they send you a new one.

Hmmm, this is interesting. I cannot even format the microSD card. I tried to do it through Windows Explorer. It looked like it worked. I then tried to copy files back on and it choked halfway through on a movie, I think.
Anyway, what was more interesting is that when I looked at the drive again, everything was back where it originally was. So, the re-formatting must not have actually worked.
I then tried to erase the SD through the options in Android. I unmounted. I then selected Erase SD card. After rebooting (to just be safe), the SD card still is untouched.
THis microSD card has become an impenetrable force. More realistically, it must have write-protection enabled somehow as that is the only thing I can think of.
The question is how do I find out if write protection is enabled and how to disable it? Any ideas are appreciated. Thanks.

Removed SD card before unmounting

Okay, so it was a emergency and I had to remove my Micro SD card, so I couldn't unmount it.. Later that I day I was about to play some music when I realized all my songs where gone! .... The same with my pictures that were on the card! (ALL MY NYC PICS FROM MY TRIP I JUST WENT ON ARE ON THERE).... Did removing it from the phone actually make the date unusable or was it when I accidentally hit format SD card but, as soon as I hit it, I hit stop!!! This is crazy, for this had all my NYC pictures on it :/
On a Galaxy S2 Skyrocket, that is not reading sim cards, but the sim works in other phones. Could it be that I left it in Airplane mode so long? I am not rooted, or anything like that. Any fixes?

Does the PC reconize the card? If it does but doesnt open you might have chance recovering your data from it, if it shows up as empty your chances are pretty weak (tho with some software you still may be able to get your files back, i have even got my files back after formatting my hdd and renstalling OS). if it shows up as empty, do not copy new content on there

If you go to Transcend website they have a recovery program called recover rx. You can recover lost files with this. I had also once faced a similar problem where all my photos got wiped out by trying to download using a cheap sd card adapter. I used this software to recover all my photos.

try to explore the sd from the pc,mabye it's simple a bug

I have LG P990, which install ICS4.0.4, when i insert new SD card, i dont have mount or format option for new SD card, is that normal, i did download bind application for Music and Movie application to find my song and video. i need bind it every time, what can i do to mount new extra SD card to internal SD card?

This software is really simple free and I have found really good. Recuva.
Install on a PC and connect card select drive on recuva, and start it.
Very simple
If the problem is just deleted data or formatted drive
