New SD erasing apps when restarting phone!!

So I bought this sandisk 32g microSD (overkill, I know off eBay for $20. I thought it might be a fake but it seemed legit as the seller was 100% feedback. It arrived in its original packaging. It says it a class 2. It also has its full 31.2g of space. I formatted it before use. It checked it write and read speeds. They are the same as the SD that came with my phone. Now every time I restart my phone about half the apps I have moved to my SD card disappear. I don't really know why, and I kinda do wanna use this card. Help please?

Use H2testw to test your sd card and see if its fake or not

Like the other one said, the problem is your SD card.
It happened to me when I bought 2 32 GB card from ebay at low cost.
In fact, they flash a 32 GB firmware on a 1 GB card.

Can't say I'm surprised. Thanks. Also what is H2testw?

its a program for detecting counterfeit usb drive or flash memory card
you should try to use that on your sd card and see if its "real"
i don't trust any sd card on ebay any day
always buy from legitimate reseller

D2G not liking my new SD card

hey everyone, i recently got a new Patriot 16gb class 10 micro SD card, and its blazing fast, but i have problems with it, it works perfectly fine when i format it but once i start syncing my music to it, it causes my phone to freeze up and starts FC'ing all my programs, and when the screen turns off it doesnt turn back on and i have to reboot it. When i put in my old SD card it reads and functions perfectly.
what could be causing the problem? i have the exact same files in my new SD card as in my old one, so it couldnt be any of the files, can the D2G support class 10 SD cards? i tried SBF'ing and starting fresh but i still have the same problems, and formatting the drive and syncing the files again doesnt help. i even used h2testw to verify that the card isnt fake and it isnt.

You really need to stick to Kingston and SanDisk <= class 6

unfortunately, the droid series of phones dont support class 10 cards, it took me a very long time searching, but i found that out. either way, i traded my card for a class 6 card with my friend, so im fine, even though i downgraded, thanks.

I wouldn't be surprised if it could be patched at some point to support class 10.
But probably not on a locked Bootloader of the D2G

From what I read, its the hardware that doesn't support class 10 cards, from what I read only the desire HD class of phones and the atrix support class 10 cards

ok, what the hell is going on? i put in a 16gb class 6 card in my D2G and it acted up in the same way it did with the class 10 card, same thing with a class 4 card, what the hell is wrong? this is really pissing me off because ive wasted a lot of money on these sd cards, and none of them are working, my D2G only seems to like the standard 8gb that came with it.

Brand matters. Make sure it is either SanDisk or Kingston...

Did you unmount and then remount the cards?

i tried everything at this point, if it doesnt freeze my phone it cant unmount, the few times i manage to unmount it and format it, i try to sinc my files back onto it and it starts freezing up again, im pretty sure at this point that its something wrong with my phone and not the sd cards, this has been happening with every 16gb sd card i can find

No offense, but are you sure it is indeed a SanDisk and not a Chinese cheap fake clone?

Yes it is indeed sandisk, I bought it off of newegg, not ebay where they sell the chinese clones, I ran h2testw to ensure it was up to spec and it is.

so no one knows whats wrong with it? im thinking i might have to rma my phone...

I'm having a similar issue with my D2G, and a 16GB Class-4 Lexar SD card. I used 'rsync' to copy all my data from my 8GB card to the 16GB, and it will boot up and work for a minute or so, then it either freezes up, or the screen turns off and I can't turn it back on again.
The only thing I have not tried is to use the phone to format the card. I almost want to say that when I first installed it, it seemed to work, but I didn't want to have to redo settings or re-download apps that are on the SD card. Maybe there's some data messing it up. I used 'rsync' so it should have gotten all the .hidden files, and respect any permissions, so I'm not sure what the deal is.
Maybe I just need to spend some time, and reload all my apps and redo my settings that might have been saved to the SD? Anyone else have this issue or something similar?

I just ordered a 16 gig class 10 and hope that it will work.... as it is a pain to return. Have heard that there is a great speed advantage to using the high speed card and sideloading most photo Apps to the card. Did u get the card to work in the end?

my class 4 16GB card worked, it was any card that was of a higher class that didnt work, to this day i still have my 16GB class 6 card that causes freeze ups and reboots on my phone no matter what i do, i have no idea what causes it to act that way, but im pretty sure that this phone has a class limit of 4

Hi,
Did you copy everything from your old card to the new one, or just start "fresh" with the new card?
Also, did you use the phone to format the new card, or just start using it out of the box?
Many thanks...

i pretty much tried everything, formatting it on my computer, formatting it on the phone, copying files over, starting from scratch and syncing my music, every time it would start out working fine, but once there were a few files on the sd card it would start freezing up, the thing works just fine on my friends inspire 4g, he had it before me and had all his music and files on it and it worked flawlessly, i dont see why it doesnt work on the d2g.

I'm unable to get my class-4 16GB card to work with my D2G, so I'm going to exchange it for a class-2. The phone is supposed to be able to take up to 32GB, correct? I'm starting to think it's an issue with anything > class-2 speed.

the sd card that the phone comes with is a class 4, and my class 4 16gb card worked, it might be your sd card as someone said earlier

Damaged SD Card

I'm starting to get really annoyed with either this phone/android or cm7. My SD card apparently has been "damaged" yet again for the 2nd time in 2 days while the phone sat at idle. I have a backup of all the important items but this is beyond annoying to keep reformatting sd cards. Any ideas as to what might be destroying my sd card?

What's the default capacity of the card? If it's 8GB, is it the card that came with the phone? If it's not that card, did you buy the card from a reputable vendor? There are entirely too many counterfeit cards floating about these days.

It's a 16GB Class 6 card I bought on Amazon. Forgot the brand and it's not even listed on the card itself. I think it was Komputerbay. That's probably my issue.

Hmm.. Was the card sold directly by Amazon, or was it a 3rd party just selling "new/used" stuff via Amazon?

Nah it was from a 3rd party. I was being cheap and found a 16GB Class 6 card at a good price so I figured who cares what brand it is and I guess 4 months later is when I'm paying for that.

Something to try, rather than reformatting every time, is to mount the card on your computer and run fdisk. Try this link for more info: http://forum.xda-developers.com/showpost.php?p=4112485&postcount=9

I'll give that a shot when I get home and more than likely I'll be smashing this card and using the stock 8GB card till I can get a real good card.

Yeah I'm betting it's a cheap p.o.s. card. Good thing I got my invite to Music Beta today! I'll upload my music there and be fine with the stock 8GB card.

Another thing that seems to work for me when I get "Damaged SD Card" or "SD Card Unexpectedly Removed" is boot into Recovery, go to Mounts and Storage, and make sure all four partitions are unmounted. I don't know why they are mounted on boot, but it seems like when I get an SD issue, I go into Mounts and Storage and one of them has to be unmounted.
This usually happens when I have recently mounted USB storage to transfer files to/from my computer. If anybody has some insight into this, please speak up! Thanks.

Warnings with SD cards for A2

So I recently ordered a Sandisk Class 4 16 gb sd card for my Atrix 2. I wanted to be able to keep a backup of a ROM at all times while having 500 songs on my phone..but 2 gb just didnt cut it.
So i tried to connect the card with my phones USB cable while having it in the device, but it just wasnt showing up on the computer. I had to end up using a card reader.
It still works...just something to keep in mind while buying SD cards.

In order to view files on your sdcard on your computer, you have to select the "USB Mass Storage" option.

thats probably it. I had this happen off and on until I let android format it. my recomendation would be to put it in your computer and format it as fat32 then put it in the phone and have it format it

Thanks a lot ill try that

Although problems do not seem to be prevalent with the slower class cards, it might be a good idea to follow Patriot's advice regarding formatting. The suggestion was posted by Patriot in response to a review of a 32GB class 10 microSDHC.
Patriot acknowledged a problem with hemorrhoid OS and 32GB class 10 cards and suggested a temporary fix of performing a full format on a Windows PC with a 32kb allocation size, obviously FAT32 since stock hemorrhoid does not recognize NFTS.
The reply can be found in this review although the specific page will change if more reviews are added.

Be patient... they'll likely come sooner or later.

I got a 16gb class 4 sandisk and I am formatting it in my computer using following method:
I inserted the memory card in my E71 and connected it to my computer in mass storage mode. Then I started formatting using fat32, 32kb through my computer. But it is taking ages. Since last 2 hours, only 35% is completed. My questions:
1) Can i stop the format in between ? Or will it lead to certain faults?
2) Is the format this slow? Or should I try formatting it by putting it in adaptor and putting the adaptor in laptop slot and then format?

I remember reading somewhere that some class 10 SD cards don't play nice for the Atrix 2. If that is so then what brands are the ones that do work well for the Atrix 2? I'm still rockin the 2gig, and well it just isn't cutting it.

I'm using a Kingston 32GB Class 4 card, which is actually in my SGS3 now from my A2, and I have never seen anything to complain about with it. I still hit high benchmark scores as noted with my A2 as well as my SGS3, thinking though that I may try a higher rated class sdcard for the SGS3, since it doesn't seem to have the issues that the A2 has seen. But, a little more digging around has to be done before I make that kind of jump! (Better safe than sorry!) But, yes, the Class 10 cards will -eventually- give you grief if you try to use one with the A2. Not sure the 'scientifically-proven' answer to give here, just know that from everything I have seen, which has been substantial enough for me to believe that...

You should try a re-formatting of the sdcard, as you likely have some corrupted app data/other data that is causing the rebooting. A Class 4 card should give you no problems like this, unless you have some issues like I just mentioned.
And if you're trying to restore app data from, say, Titamium Backup, I recommend you do not do this. Just try a fresh format of the card, and do not restore data to it. Run your phone afterward for a good while to test. If your phone continues to reboot after you have tried this, changes are that you can rule out the possibility of the cause being due to the sdcard, and we can explore other possible known culprits...

I just put an 8gb class 4 SD card in my phone. I formatted it via the phone twice and rebooted. My camera saves pictures and videos that say they can't be opened when I try to go play them. And Doggcatcher has the majority of my podcast downloads failing. This has persisted after a couple reformats. Thoughts?

[Q] My phone identifies the SD card and data on it, but few things are accessible

Alright, first let me start by saying that I hope this is in the right area and i'm sorry because i'm sure this question has been asked to death.
I have a Galaxy S 3 Running stock with android 4.0.4 (Not rooted)
I also have a SanDisk Ultra 64GB SDXC class 10 MicroSD card (Formatted to FAT32)
I have had the phone a month and for probably the first week I was using the card in the ExFAT file format...Then random card identification problems started to pop up. So I scoured the web for a short time and found that the issue could be solved by reformatting the MicroSD to FAT32 at the expense of not being able to have single files larger than 4GB. Everything worked for a good week, then suddenly the phone didnt know I had music on it anymore, my player stopped and i confusedly navigated through songs that weren't there. I removed the card and reinserted and the files worked again.
Well today the phone is doing the same weirdness again, it is identifying that there is in fact a 64GB MicroSD and the amount of data is correct. It is also allowing me to navigate to the files in ASTRO, even my PC still detects and allows me to Add/Delete files from the MicroSD...BUT my phone will NOT use it. For example, if I go to camera and want to take a picture with the destination being the MicroSD, the phone says "What MicroSD?", also my media gallery is empty (Save for the files stored in the internal storage) and my music player is empty as well.
Anyway, I didn't know what course of action I should take. Does it sound like one or both of these items needs to be returned/reformatted/smashed with a hammer?

I am not sure if the sgs3 supports 64gb cards, i suggest you first try with a 32gb card to see if it is a card reader problem or a mmc problem

If that's the case why does it state on all the North American Cellular phone websites that the phone supports "Up to 64GB MicroSD"? Seems crazy that such a large feature could be so buggy.

The GSIII (international and US) variants do support 64 gb micro sd cards. It's advertised on the box.
It sounds like your sd card is failing you. Definitely backup all your data to a computer and think about replacing this micro sd card via manufacturer warranty.
