Corrupt SD Card issues

Is anyone else having issues with their sd card corrupting? I have an 8gb class 6 transcend card and it has corrupted 3 times in the last month. I always unmount the card in windows before unplugging the phone. It seems to do it when I'm writing to the sd card from the phone.
The first time I noticed it was when I deleted a picture with built in photos app.
The next time was today when I made a nandroid backup before applying an update (theme). The nandroid backup finished and when I went to apply the update it came up with an error (I didn't reboot between the backup and applying the update). I reset the phone and the sd card was unavailable.
At one point I did have the card partitioned with the apps on one partition. When it corrupted I reflashed the phone back to 1.42 and left the apps on the phone. I went back to one partition and left it at that (fat32).
I don't know if I just have a bad card or something else is going on. I never had any problems with 1.41. However because it did it while doing a nandroid backup would that rule out the software version?
I would like to find a solution, as I don't trust the card anymore without backing it up frequently.

i've had it happen once (files names corrupted) but assumed it was down to the card as i had the same happen when it was in my N95, i've now bought a new card and i'll see how it goes.

When mine goes down, it seems like it kills the partition. When I open a disk manager I don't see a partition on the card anymore.

Hey axion,
Yea your card is pretty much dead... this also happened to me yesterday on my 4 gig card... yyour card will still work however reformatting or creating anymore partitions won't help bring it back.. for future update.zips or recovery boots upload your update files to your stock 1 gig card.. remember to always safely remove hardware with any card mounted to the to a computer..

YES - and not only have I had the same problems, it's with the same brand card! Transcend 4 GB Class 6.
My phone started having issues where I installed an application and it would act wonky, then if I tried to reboot it'd lock up into an infinite loop.
The last couple of times, I solved the loop by doing a fsck on the partition in GParted (booted into a GParted Live instance from a laptop using a USB stick). The problem reoccurs though, making me think there's something problematic with the card.
There's an app in the thread on the cheap 8 GB cards (of which I'm holding my recently received shipment . There's an app in that thread used to test write performance, but it does some crude error checking, and I had an issue when I did that test.
I'm going to do a partition clone and report back.

my dodgy card was 4GB Kingston, one interesting problem i had with it was video refused to play, i could read and write the file fine but android would refuse to play it and meridian video player would report the wrong pixel size, time and codec which had me confused all last weekend.

I'm also frequently having problems with my 8gb card (http://www.newegg.com/Product/Product.aspx?Item=N82E16820211341). Every few days I find myself firing up Ubuntu to fsck it and I always find errors. I often discover them when looking for a file on the phone (I usually do a find / | grep whatever and notice that I get "stale file handle" errors).
Should I get a newer/better card? I'm happy to pay more for a better one. I didn't know this brand, but it was the only class 6 I could find. If Sandisk made a faster card I'd get that, but I can only find a class 2. I have a 16gb Sandisk but it is only class 2 and therefore not good for apps, which is what I'm using the sdcard for.
If anyone can recommend a better one, I'll give it a try.
Does a 16gb class 8 exist yet? What about a 16gb class 6?

I just moved to the same card you have, mlevin - so I'll post back my experiences if I'm seeing anything.
I'm wondering if maybe moving the caches to SD isn't the greatest idea, since these devices aren't meant for continuous writes. If I have more issues, I might just move the caches back to the onboard memory.

Yeah, that worried me as well, so I moved my caches back to the main storage and only have app, app-private and data symlinked to the card.

If you are having problems after moving apps and data to your ext2 partition, you have to push the original init.rc and mountd.conf back onto the phone so you can wipe to card fully and restore it to the FAT32 file system.

I had a similar problem on my tmobile wing (variant of the Atlas which is a modified version of the Herald) running Windows Mobile 6 and Windows Mobile 6.1. I think it was also when I used the SD card as a place to store cache for PocketIE. Maybe that's the issue, using it as cache storage. (This is my theory, not something that has been confirmed.)

g1 sd card deletes itself
I am on my 4th sd card. I am not sure what is corrupting/deleting my data. I can copy over some music/video/pdfs/wtfevers and it'll stick around for awhile. Then BAM, music folder empty(had 1 gig of music in it). BAM, 1 of 3 video files corrupted. OH wait, now all 3 are gone. awesome. I keep a backup on my pc so I can copy it all back over once it goes south. I have the doodledroid drawing app on my phone and the folder will go corrupt - not allowing me to save an image until I delete the folder so it can reinitialize(create a non-f'ed up folder). Also, my picture thumbnails get f'ed so I have to delete that folder so the G1 can remake a new non-corrupted set. My PDFs disappeared about 3 days ago. Cards all formatted fat32. blah.
Frustrating.
I have root
kila-user 1.1 PLAT-RC33
Anyone else find a solution?
BTW, my sd cards were:
sandisk 2gb
sandisk 2gb
PNY 4gb (current)
Lexar 4gb

mlevin: I have that card. It's been fine...until I believe the other day. I was running 5.01H w/ apps to sd and my battery had died so I charged it. Upon turning it on the android screen kept looping as though it wasn't mounting the card. Worse came to worse and I had to end up reformatting the card and starting from square 1. Now that I reformatted it, I'm getting "insufficent space" errors when trying to install paid apps even though I did everything right.
I'm wondering if it is the card.....

[Q] ACER LIQUID E - 16gb card "checking for errors".....

Hey all.
FIrst off I dont recommend this phone. haha, that being said...
I just bought a 16gb microsd card for it. I was able to install it and transfer a bunch of tunes over. Then when I disconnected it from the computer, it has a little sd card icon with a sprocket at the top left of the screen and says "checking for errors". As a result, I dont have access to the info on the sd card > music contacts photos etc.
Its been 12 hours or so and this status has not changed.
Can anyone shed any light on this issue? Has it "farted" or do I just have to wait...
Thanks.

Have you tryed turning the device off taking the battery and SD card out then putting it all back and turning it back on, had issues with my phone not recognizing my SD before and it worked for me, just give it a try and see.

Thanks, but tried that many times...
I did try removing the battery and card multiple times to no avail.
I even sacrificed my programs etc through a hard reset. As soon as the reset completed, I have the same notification about the sd card.
Some details...
When I first inserted the 16gb SDHC card, the phone acknowledge its presence and I formated the card in the phone. It said there was over 15gb available... all fine...
I then was able to que it up with my pc through the USB cable and transfer about 8 gbs of music to the phone... transfer when fine.
Upon removing the phonne, it started with this "preparing sd card, Checking for errors" nonsense.
I am firmly convinced that there ACTUALLY is no SDHC support on these Acer Liquid E phones. My old 2 gb card that came with the phone works just fine and is back in the phone now. My only other option is to buy a 4 gb card and see if that will word fine, as 4 gb is not considered SDHC. then step up again to a 8 gb card (SDHC) and see what happens.
Does anyone else have a SDHC card in there Acer Liquid E? Does it work?
There is also NO help from Fido or Acer to work through issues...
Really makes me want to go back to the iPhone........ grrrrrrrrr....

Make sure that you formatted it to FAT32 first of all and does the card still connect to the computer using a card reader ? Why don't you try formatting it on your liquid by going onto storage and then unmounting it then format.

Thanks... no go though. At wits end...
Thanks for your attention!
When formatting in the phone, it doesnt allow you the choice to format specifically in FAT32 or other. I can only assume it is formatting in the proper system.
As for mounting and unmounting (what I feel this phone has been literally doing to me for the 6 months i've had it.lol)... as the sd card was stuck in this "checking for errors" sequence I had no access to mount or unmount the card or reformat again. These options were simply greyed out and not accessable.
I have not placed it into a card reader to reformat through my PC. I will try this step next and see what happens. I will have to find a card reader, or perhaps plug it into my camera as the card came with an sd adapter... see if that route will work.
Regardless. extremely user non-friendly phone here in the Acer Liquid E.

[Q] USB Mass Storage Won't Register

When I connect my phone to my PC (Windows 7 Home Premium) i get the notification for how to connect. but choose USB Mass Storage, it will not connect. sometimes if I wait a minute or so it will, an occasionally it will just work. Sometimes it will also work if I chose windows media sync and them explore on my computer, but not always. This is driving me insane since it won't do anything consistently. The problem started a while ago. Not sure If I had rooted yet at that point, but I was on a stock rom. Currently running Supercharged V5. any help would be greatly appreciated

If you have any apps stored on your SD card, it can mess it up. I had bootstrap stored on mine and was having similar problems, removing the apps should solve the prob.

No Apps on SD Card
Don't think that's the problem. I keep all apps on my phone because there is more than enough space and my SD card is full of music. it is a fairly low quality card though. Could that be the problem? I'm not exactly sure what class, but it was super cheap

I heard of class 10 SD cards having trouble, I have Samsung class 6 in mine and it is working fine.

[Q] flashing SD to internal memory f**ked up my device

Hello!
Well, about a month ago i've bought a brand new moto g 2015 8gb/1gb and all went well untill i flashed the external SD card to internal memory and moved the data to it, then my nightmare begun *evil/dreamy music plays*
- the home button do answer when i tap it but there is no function on it
- notifications are not displayed at all...
- moto screen not working
- lockscreen not working
- battery charge speed decreased considerably
- cant reach to quick settings
- factory reset button locked (gray letters, cant tap it)
- moto gestures not gorking
- the phone get really overheated while charging
- some other functiones are locked (same as factory reset)
As it was a brand new phone, i sent it to motorola so they would provably fix it... and they did..... Once i get back to my home with my phone working at 100%, flashed the SD card as internal memory before installing any app on it, so guess what! SAME PROBLEM ALL OVER AGAIN
hopefully i've downloaded an app so i could factory reset and it worked. my question is (if any one know) why is it happening??? now i cant flash sd card as internal memory coz im afraid it will break my phone all over again...
ANY GUESS?????'

If it happened with two different devices and the same SD card, I'd say the issue is the SD card. Just a hunch.

Nope

I wouldn't say that SD cards are a "one solves all" subject. Wouldn't surprise me if Android just didn't like the SD card you have as internal for some odd reason. Maybe you could keep it as a backup and buy a newer card unless the one you have right now is already new. If that's the case, I would just return it.

Needs to be UHS or better to work as internal reliably. I tried an 85Mb/s card and it still failed after a short time. Not sure that was all card speed, though. I think Mm also has issues setting default permissions.

SD Card slowing down Android ?

Hi, It's my first post here on XDA-Devs.
Here's how my story goes. I bought an ASUS ZenPad C 7.0 few days ago (Less than a week maybe). It was working great. I didn't install many apps (only 2-3 till now). It was working great until yesterday. I bought a SD card (32 GB) which is full of study content. All the content was already in it when I got it.
My device supports upto 64 GB expandable memory. But when I insert it into the tablet, the tablet lags, lags terribly ! It lags so bad that I have to forcefully shut it down. I can't remove the battery so have to hold the power button for 30+ seconds to do this.
My thought for the reason :
1) The ZenUI keeps crashing, even without the SD card.
2) The android on this device is not well coded. It's bugged. Alarms keeps on vibrating the device until I force stop the clock application.
I think I should root my device and install cyanogenmod because it's far better than what i received in the package. It might fix the alarm and UI crash issue and the most important SD Card issue.
That's all. Help me please.

I've certainly read of issues with the ZenUI before, so if a root is available and you're comfortable doing it then it may be worthwhile.
But what do you mean that all of the content was on the SD card when you go it? You purchased/received it loaded with content? Have you loaded the SD card into any other devices or a PC? Do other devices lag in a similar manner?
Also, have you tried loading any other SD cards into it? If you have any empty one, or maybe one with just a few photos and/or songs, that could be a useful test.

try factory reset and again configure it with the sd card insertes in it

The SD Card was loaded when it was purchased. And I've tried other SD card (4 GB) and it didn't lag. I Can't try this 32 GB SD on other device as it's won't work on a device with different IMEI number.
Maybe the SD card is the problem ?

I've already tried that. Doesn't work. As i said, the tab lags only when the sd card is inserted.

maybe there is extra load from the study material.
does that have any auto run feature on windows. that allows ypu to open and access the contents

Well the Asus ZenPad you got is only listed with 1 GB of RAM and a fairly modest resolution, so if there are graphics automatically loading when the SD card is put in then it may be creating the lag on the device.
But you say that the SD card will only work with that device? That seems strange to me. What happens when you try putting it in a PC? Or do you only have the ZenPad to work with?
Do you know what brand the SD cards you have are (both the 32 GB that doesn't work and the 4 GB that has no issues)? And is the 4 GB card completely empty? Have you ever seen any notifications with the 32 GB cards that it is unmounting from the device on its own?
