SD Card Intermittently disappears until Soft Reset?

Hi
In the last week or so my SD card has suddenly started disappearing until I soft reset the device. If I remove and reinsert a different card this also does not appear. The only way I have found to resolve the problem is to do a soft reset. It will then be visible for a day until it disappears again.
I haven't been able to narrow it down to a specific application or action.
Has anybody else seen this (or even better know what the problem may be?)

I have had the same problem i found it to be "Spb ToPlay" everytime i used it if i stopped it playing i lost all sound on my XdaIIs and the SD card went missing. removed the plug-in and havent had the problem since...........................do you have this plug-in? if you dont then i have no idea sorry i couldnt help.

I have recently installed spb time but it doesn't conincide with my problems starting. I may try disabling it to see if that makes a difference.

this has happened to me before, but i didnt have anything like you mentioned installed, so it must be a bug or something!!!

I found on my M1000 that the card will not be visible when the battery gets low, most times it gives a message like "the power is too low to support the device"

Happens to me with my O2 XDA IIs. When I contacted O2 about it, guess what their reply was?
Reply number 1:
"Thank you for choosing O2!
With regards to your query below, you may like to remove your storage card and monitor the device. Please note that O2 Asia has tested with different brands of 256MB SD card and works fine. However, storage card of larger size may not work properly and cause the device to hang. You may also like to test your unit with another storage card to verify. Hope the above information is useful for you. Thank you."

"With regards to your query below, you may like to perform a hard reset and
without restoring back any data back to the phone, try to change the
landscape again and see if the problem still persist.
**To perform a full reset:
Warning: Clearing memory deletes all data and restores the Pocket PC Phone
to its default settings. Programs installed at the factory remain, while
data you have created and programs you have installed are erased.
Before performing the full reset, use ActiveSync to keep a backup of your
Pocket PC Phone data so that if you need to clear memory, you can restore
the data on your Pocket PC Phone.Do not use Xbackup on your device to do
backup for your data.
To perform a full reset on XdaIIs, press and hold the power button, and then
use stylus to press the soft reset button at the same time. After the full
reset, you will be prompt to recalibrate the touch screen.

What a load of crap!

Lingering EVO issues (SD Card, Camera, etc.)

I'm having some lingering issues with my EVO even after running OTA updates. I am running a rooted stock ROM, currently software version 1.32.651.6 (I have not attempted the latest OTA update yet).
In particular are two problems - SD card issues have remained even after the OTA update. This was present even before rooting but after installing the first update (I went to a "full-service" store on opening day and they set it up themselves, assuming everyone would want it - luckily I could still get root). Issues include the Camera application reporting permissions problems randomly when trying to save pictures to the SD card, HTC's music application freaking out and coming to a near freeze trying to crawl the SD card during one of its troublesome spurts, and files disappearing from file explorers. So basically run of the mill, pre-first-OTA sd card problems. But occurring after the update and both before/after rooting.
Second is a problem with the camera itself. When first booting, HTC's included photo/video application will instantly crash after showing the camera icon on the black background. Google Goggles freezes for about 10 seconds then reports it was unable to connect to the camera. After the phone being on for about half an hour, these issues (seemingly) go away until the next reboot.
Last, and least frequent but still troubling, is a problem with the device powering on. At least twice I have been unable to get the device to turn on after powering it off, forcing a pull and replace of the battery to get it working again.
As far as I know, all of these issues could be either hardware or software. Even the power problem - my best guess is that the phone never powers off fully, but is instead locked inside of a deep sleep state and thus can not turn on until a battery pull forces the entire system off.
The questions being - first, are there any known solutions to the above problems? I have found many threads in particular regarding SD card issues, but none that seem to report these problems post-update. The others I have seen little to nothing about.
Second - if there are not known solutions, would it be prudent to return the phone as it may likely be a hardware problem?
Since it seems I'm forced to take the last update if I get a replacement, I may likely have problems getting a full root back. I'd like to avoid that if possible - having root works wonders for doing application development using non-native (unexposed) API's (Which - side note - since I'm developing for 2.1 at the moment, other than hacking for direct access to a Surface, does anyone know of a _fast_ way to do direct blits from native code? glTexImage2d is insanely slow).
Thanks all any help. Again, apologize if any of these are solved and gone problems, but I wasn't able to procure anything myself.

I'd go for the replacement, sounds like a defective unit..
Be sure that the folks here at xda will get root working regardless of OTA.

replace the unit, i'm very particular about my phones, if there is anything wrong with it I replace it.

I too have the SD card issue, I have updated, i have rooted, re-rooted, flashed new rom, different roms (fresh and sd) and it has always given me the sd card issue. Sometimes it wants to be a pain and not work at all, sometimes its good for at least a week or two. I am waiting for a little longer to make sure when I get a replacement its a newer version.

SD card permission errors --- POSSIBLE FIX
I hope/think/believe I fixed this error for those interested, I use my EVO for work and need it to work without a hitch....
Here goes (**Note i am a noob with smartphones with a dangerous amount of IT knowledge - disclaimer for those brave enough to browse around the root files and SD card files; I am not responsible for you bricking your phone, I am only trying to help those in need and putting in my 2 cents_)
Download and open the app ---> Root Explorer (or any other root explorer for that matter) from Android market.
Once Root Explorer is open (look up top/left it will say) Mounted as r/o (means read only) - press the white button to mount it as r/w (read & write)
Press and long hold on the SD card directory (folder) - you will get another window from which you must select the permissions option.
Under top option USER - check all marks -- READ WRITE AND EXECUTE & click OK.
VERY IMPORTANT - Click on the (white button) Mount as r/o to write protect your root files on your phone again.
I just applied this fix about 45 mins ago and seems to be working......updates to come if issues persist or re-surface. (**Note I could not see photos or play music and some apps were also giving me FCs (intermittently) due to permission or write errors to SD card; and now it seems to be working like nothing ever happened.)
What I have ::: stock ROM on EVO supersonic with recent HTC updates applied - standard 8Gig SD card provided with phone / had rooted but put back stock ROM for preference issues.
Hope this info helps some folks...very frustrating issue.
Cheers

SD card permission errors --- POSSIBLE FIX
ONE LAST SIDENOTE COMMENT -
I transfer data to my PC often (running Win 7 32bit_)
It is crucial that you right click on "safely remove hardware" icon on the lower right side (next to date and time) and WAIT until windows tells you
..."It is now safe to remove your hardware" --- I was just taking the plug out when done and it appears as if that could have started or compounded these issues with the SD card.

I too get the could not connect problems at times. And I have lost access to the SD card a few times. Some say its Fring that causes the problem. But after removing it I still have camera issues. I noticed that having the LED Light on while trying to open the camera will cause this problem.
I am running CM6 RC1 so this is to be expected from Release Candidates. Sit tight. It will get fixed.

Well after a full 24 hrs...no issues with the read write error on my EVO SD card, I think that when the phone is removed from PC incorrectly (i.e. pulling USB cable out in mode other than "Charge only" i.e. HTC sync, Disk Drive, Internet sharing - it causes it to "corrupt" the permissions on the SD card - It is still working like a champ and i am waiting impatiently for my EVO Froyo update ... feedback appreciated for those whom tried this fix and had it work....txs

@LF142
Hi there. So I followed all of your instructions above and downloaded Root Explorer. However, every time I change the permissions, they don't save. User, Group and Other is always switched off at root level. Do you think this may mean my SD card is corrupted?
I rooted it with BakedSnack.
I now want to un-root it as I miss taking shots, looking at my shots, listening to my tunes etc.
But I want to keep all my apps. All my texts and everything else. Whats the best way to go about this? I am also a bit of a n00b and I apologize if this is in the wrong forum, but when Froyo releases tomorrow (apparently) do I have to unroot to receive the update?
Thanks

Some applications and files disappear from SD card after SAFELY removal in Windows 7

Good afternoon, dear xda-developers forum members.
I really hope to find some help here.
In last two months I had the following issues:
1. This one happened two times already: after using my phone as a flash in windows 7 and "safely removal" of it, all my applications which were installed on SD card were saying that "Application is no longer installed" when I tried to run it, although other documents and files were readable from ASTRO File Manager, i.e. SD card was mounted. In Settings->Applications all these applications had black icons with SD card image on it and rather with package name than regular application name(for example com.navitel instead of regular Navitel, etc.). I've restored all these applications from Titanium Backup, but I'm afraid that there is something more disappeared also which I don't know about.
2. My "Android" folder on sd card became a file with weird contents(this folder was used for NFS Shift data only). I couldn't restore it. Again: if this folder corrupted, then there is definitely something else also corrupted.
After I saw these things for the first time, I used Windows checkdisk with auto-fix errors. It found a lot of files and put it into "FOUND.000" directory. I recognized in these files few apk-files of installed applications from SD and also few images from my SD. Then I restored applications to SD card and for some time it seemed ok. But one time it happened again.
My assumption is that Android fails to re-mount SD card after I disconnect it from PC.
I don't know what to do... is it Android bug or is it Desire bug or what? I swear that I ALWAYS make "safe USB removal" in Windows before disconnect the USB-cable and I ALWAYS wait for the message "It's now safe to disconnect your device".
I'm very disappointed with all that Please, advise me something useful...
P.S.: If needed I can give you any debug information you want, I'm a programmer, so I've been around

You could try to format your SD card, just backup the contents first, see if that works. As for Android, it does a pretty good job of mounting straight after. What version of Android are you running?

I will, but strange that it happened, because I formatted the flash before using it for the first time...
I have two assumptions:
Maybe I shouldn't press power button to switch the screen off just after disconnecting USB cable from PC. I was doing that as a habit, because every time you disconnect your phone from PC, the screen turns on.
Maybe I shouldn't try to run application which is installed on SD just after disconnecting phone from PC. Maybe I should have waited for a minute. I've tried to do it once, because I wanted to see the result as soon as possible, so the phone said that "Application is no longer installed", I though that Android haven't mount SD yet and tried later. It worked. But next time when I used USB cable, all SD-card apps became uninstalled.

I'm sorry, forgot to mention. I'm using HTC Desire with Android 2.2(2.10.405.2).

Fast Boot option may be the culprit
In case anyone checks this old thread...
CUT TO THE SOLUTION BELOW -- SEARCH FOR ////
Some (not all) of my apps moved to SD (all by Titanium Backup Pro) have begun to disappear and (sometimes) reappear without warning after I began to add and delete large Virtual Machines created in QEMU from my 16GB SanDisc class 10 microSD card on my HTC Droid Incredible running rooted stock Verizon Android Froyo 2.2.3. I know this thread is far from my phone's "home base", but from what I can tell this problem with disappearing apps located on an sdcard is NOT determined by hardware or even Android version.
I also happen to use LauncherPro by Federico Carnales instead of the built-in HTC Sense launcher. I noted elsewhere on XDA that a user had suggested that because at least some (maybe all) launchers start before the SD Card that this may be a problem, especially if changes are made to the sdcard that the launcher did not perform, or was not active during their performance by other apps such as Titanium Backup. That fits my situation, because I unmounted the SD, physically removed it to a PC, and added/deleted large VM files to save (lots) of time. No problems of this sort before I did this, so there must be some connection.
I noted that other users have tried reformatting SD, substituting different brands of SD, using newer/older SD etc. None of these reliably helped. So I skipped these options.
//// The (simple!) solution I tried that SEEMS to work (only time will tell!) is buried in the main Android Settings (accessed from the Menu button while in Home screen). Under "Applications" there is a setting "Fast Boot" that I checked long ago and forgot about (it seemed like a good thing to do at the time). The text warns "Turn off to use some Market apps" (that shows the age of my 2-yr old used phone and Android OS -- ohmygosh!-- because it refers to Market rather than Google Play Store!) Anyway, I unchecked the option and rebooted the phone.
Yes, it took a bit longer to boot (maybe a whole minute!), but after waiting about another minute ALL my home screen apps had normal icons and loaded properly. Titanium Backup Pro batch scenarios confirmed there were no apps in a forced uninstalled state (i.e. I had not done the deed, the system somehow had done it or at least rendered the apps "invisible" to Titanium, which decided they needed reinstallation).
The only odd behaviour was that auto brightness was turned off after I unchecked Fast Boot and rebooted. Going into Android Settings > Display and rechecking "auto brightness" took care of that. No other oddities or strange behaviours thus far (but it has only been about an hour).
I will report back here on this thread only (Samsung Fascinate > Fascinate Q&A > What just happend? apps on sdcard) if anything else requires reporting. Silence implies success!

[Q] Phone resets to Jan 1, 7:00pm after restarts. Many apps not working.

I've been having a very odd bug that started to occur today.
Whenever I restart my phone, battery pull, or turn it off and on it resets to Jan 1st at 7:00pm. Some apps are not working, including BBM (msgs don't attempt to send), Snapchat (gives me a "Google Play not supported by device" notification), and Google Play (no connection error).
Because my phone is "in the past", whenever I send or receive texts they do not appear on the message log due to their time stamps being in the future (I assume so).
What should I do? Should I wipe and re-root. I'm running Liquid Smooth JB 4.2 ROM and have been for nearly 6 months for no issues. I wouldn't expect it to be the ROM.
Another thing, If I do wipe and re-root, how would I completely wipe everything minus the core things? Let me elaborate: I've been having a problem caused by CWM where it is creating multiple "0" folders (which are created to store all the files every time I install a new ROM). I think it's at about 7 files deep now due to switching ROMs daily about 6 months ago. This leads to a very messy internal SD with files all over the place. How would I fix this so it goes back to the normal file structure, pre-root? Do I have to go delete the files by hand on via my PC?
Another thing, what method is recommended to save my People contacts, messages, app data, etc (preferably on an external back up: PC or external SD)?
Thanks in advance!

Bricked Oppo Find 7

Hello,
I have an Oppo Find 7 for a while and I always thought that the Color OS is not very good, and specially, it comes with a very limiting partition division.
So, when I could no longer decide on which Apps to keep and which to uninstall, since I had no longer space left on my phone due to the stupid small partition for applications, I decided to format my phone, reconfigure the partitions and install a new ROM (CM 13).
I had done it often on my lapton, how difficult could it be to do it on the phone?
It all seemed to work fine, but when I started my "new" phone with CM I noticed that something was wrong. I tried to use the camera and it showed an error saying I did't have a storage device.
Well, I was sure I had left enough space for photos in the other (not OS) partition, and I had also the SD card.
I went to Settings->Storage and I saw that my phone was recognising the OS partition only (about half of all internal storage) and had a portable storage device called "sdcard0" (not the actual SD card) reading "Damaged" below.
I've tried to erase and format that partition, but it shows an error reading "command '41 volume partition disk: 179_0 public' failed with '400 41 Command failed'".
I've tried to rearrange the partitions again, to reinstall CM13, but nothing worked, so I just accepted that my phone could not take pictures. Everything that did't require to have a file system worked fine (well, I cannot see the naked ladies pictures my friends share on whatsapp). This was a few months ago, so I don't remember precisely what I did.
Recently I decided that I actually need a phone that takes pictures, so I went back to trying to fix it.
Unfortunately, I can't. At least without some custom help. I've read plenty of tutorials, forum pages, but there's always something that doesn't work in my case.
Here's what I can do with my phone:
- It boots
- It works
- Computer recognises it
- adb recognises
Here's what I can't do:
- Have any files (the file system is broken)
- Take photos
- Restart with bootloader - when I tried, the screen just shows a sitting penguin for a few seconds and then turns off. I do remember to be able to do so, but I can't now.
I've tried to load bootloader though the phone's interface, through the power+volume down button combination and through adb. They all had the same result. The stupid penguin and then darkness.
Can someone help me?

Hello, you're phone is not bricked. What is the exact name of you're ROM ? Do you have make LVM, or chinese storage partion?
