My Eris has been running very smoothly for several weeks with ELB 2.7 with JIT enabled and most of my apps relocated to the SD card. But a few days ago, I started experiencing crashes when waking up the phone or answering a call, and then last night I started getting FCs anytime I tried to launch an app located on the SD card.
The FAT partition works fine, and the EXT partition appears intact when I mount it, but nothing located there will launch.
I've resolved the issue (sort of) by reinstalling the apps I need on my phone, and switching off App2SD, but now I'm wondering what the next step should be. Does this indicate that my SD is dying, or should I try repartitioning the card -- either to eliminate the EXT partition entirely or to recreate it?
just try reformatting the card...if you start experiencing it again...then your card is most likely dying... sorry...
Even if you got your Eris on the first day it came out, your card shouldn't be close to "dying" yet. Maybe it was defective to begin with. I'd bet willing to be its not the card. I know a2sd is harder on it, but I just doubt it killed it already.
Copy your apps to PC, reformat SD Card, Copy apps back, and see what happens.
Please report back, I'd be interested to see what happened.
Apps2SD isn't recommended by a lot of the devs for a reason. It causes unnecessary wear on the SD card. SD cards have a limited life span of around 100k cycles. When you access a program on the SD card it doesn't just make 1 cycle (read/write), it makes many during the usage of the program. 100k for picture taking and other standard use is quite a bit, but when an app is accessing the SD card constantly while running 100k is reached very quickly.
I'm going to take a guess and say your card is dying for reasons stated above. Try reformatting as recommended, if that doesn't work, replace the card.
The only time this would be a concern is if you moved dalvik-cache to the SD card (as that is constantly updated). When you put an application on the SD card, the data related to the card is stored in /data/data, which is not moved to the SD card (this is why internal storage continues to decrease after you move apps and dalvik-cache to the SD card).
Also, it's 100,000 cycles per block of memory. Most SD cards have wear-leveling technology that helps with this issue, so it will take a while before the card becomes bad (if it is a good quality card).
I would say he has a failing card. It happens once in a while.

yeah u gotta be very careful with app2sd
I followed the advice of several people and repartitioned reformatted my sd card. I decided to go without app2sd for awhile so I just did a single fat partition. So far so good...everything is working again.

has this ever happened to anyone? not sure if its coincidence or not, but i installed the new unstableapps overclock app and it was running at 1.3 fine, was playing a game, it froze, rebooted, then the message pops up in my notification bar that my sd card was damaged and i had to format it. not a huge deal but i lost some pics of my kids on their first field trip in preschool so that sucks. my pc wouldn't even recognize it... just wondering if anyone had any input on this?
I've been stressing my phone while OC'd playing games as well. It occasionally freezes on me, but I've never had a data corruption. I don't have any apps on my SD card, though. Was the game on your card?
Just noticed your post as I just created a thread about my SD Card doing the exact same thing today. I was just taking pictures of my kids when the Camera app Crashed. Restarted my phone and Got the same error about SD card needing to be formated. Running Stock 2.2. I'm not going to format the card until I know for sure the data is gone as I too have pictures on it I need.
yeah i think the game was installed on the card. i think i had the overclock too high. its stable at 1.2 but any higher i get force closes playing that game... maybe i'll try to move it and see what happens...
My SD Card crapped out withing the first week. I hadn't had time to root the phone or overclock it. Verizon replaced it. I think some of the SD cards are defective. This post will remind me to copy the contents of my SD card to my computer in case something like this happens again. I have most of my apps running from the SD card.
If a file is open on your SD card when an app or the phone crashes it will leave the file corrupt on the card. This will throw errors when you're trying to use the card in the phone. You should try making a backup on your PC of the SD card, then poke around on the SD card for the potentially corrupt file. If you can manage to delete it you should be fine.
I have just come back to android after a 4 year iPhone hiatus. I've got myself a S7 edge and put in a 64GB SD card.
The SD card seems to work fine until I try and download music to it from Google Play Music, it gets to 1-2% and then the phone reports the card is corrupt and cannot be used. It cant even format it. I returned the card and got a replacement which did the same thing.
With the card in a corrupted state I put it in to my Windows PC (which reports it corrupted), deleted the partition and recreated it. Used both iometer and ht2testw to fill the card to its limit and test IO on it, which did not fail. I've then put it back in the phone and tried to download music and it corrupts again.
Next I've put it back in Windows and fixed the partition, put it back in the phone and got the phone to re-format it and tried again - corrupt again.
I've fixed the partition, signed up to a spotify account and filled the card with as much music as it would hold - this works! As does every other app - camera, podcasts, copying games to run from the SD card. Its only when Play Music tries to right to it.
Has anyone seen this before? Is it a known issue? Any ideas for a fix?
You are lucky your card survived...
Here is my experience

At least sandisk I got after two Kingstons is working fine now...
Same here with Spotify also :ยง
No problems with my Samsung microSDXC PRO Plus 128GB Class 10 UHS-I
Google Play Music/Movies, Spotify, TomTom Go & Here all saves the data to the external memory...
And I've a lot of Spotify tracks offline on my MicroSD
New to XDA, not new to Android.
Phone: Moto X Play
Rom: Stock Marshmallow 6.1
Issue: SD Card disappears randomly (formatted as internal storage!!!)
Bootloader never unlocked, never rooted.
I have a sandisk 32gb micro sd card that works when I first start the phone. The problem is that it will randomly, completely, disappear.
Now I'm not, IMO, a complete noob. I am fairly (99%) sure it is indeed the sd card at fault. Ok, not an issue, I can always replace it with a new one.
The issue is, of course, that EVERYTHING is on my SD card, most importantly, my photos.
Even without accessing a file manager (phone idle, browsing web, playing games) the sd card will eventually fail leaving it inaccessible until the phone is restarted. When attempting to access my photos, which is what I need most, it fails MUCH quicker.
Having not used the "Google Photos" app before (just Gallery), I am not at all sure if my photos were ever backed up online, If they were, I'm not sure where to look.
Trying to access them via usb, wifi file transfer, bt tranfer, and even from file managers on the phone itself, result in an almost immediate failure of the sd card. 5 seconds or so tops.
The card is formatted as "Internal Storage" and I have not been able to find a way to get a computer or anything else to read it, and I would imagine for security reasons, there is no way.
Here's the question: Is there any way to get photos off the sd card, that wont take me three million years in 5 second intervals, while having to restart the phone every bleeping time the sd card fails to get it to recognize the sd card again?
Suggestions please!
Thanks in advance,

Format the card using computer (Not quick format )
Quick format didn't worked for me.
And don't make card as internal, use it as portable
with the sd card in the phone, go to settings - apps, show system apps. then select External Storage, force stop it or clear it cache. do the same to Media Storage. reboot the phone, once everything loaded wait for 5-10 minutes especially if you have lots of files in a large sd card. once that done, connect the phone to your pc (use mtp if i'm not mistaken) and hopefully you can now access the internal (sd card) contents.

This will HOPEFULLY resolve the issue AFTER I get my photos off the card!
What I need help with is getting roughly 10 gigs of data off a card that works intermittently for roughly 5 seconds at a time....

I will try this and report back.
One question... If the card is formatted as internal storage, clearing data for external storage and media storage will not cause the phone to "forget" the sd card will it?
Thanks,
Canabian.
I think I have come up with a solution to my own problem. If this works satisfactorily, I will let others know as this may help many other people facing this issue.
I am on a linux pc. I am going to try to use RSYNC to copy the files over. This SHOULD copy files over, deleting them from the source folder as it goes. Once the sd card fails, which it WILL, once I reboot the phone and start rsync once again, it should "resume" where it left off.
Here is the command for anyone else that may need it:
rsync -v --progress --remove-source-files --recursive --append-verify /path/to/source/files /path/to/destination/folder
Hopefully this works the way I hope it will. Will post back with my results when I can.
Thanks again,
Canabian.
I had the same problem, and the solution (that maybe someone posted somewhere in the internet) is using a faster SD card. Since I switched to a sandisk extreme pro, the problem disappeared. Be careful, though, when using Samsung SD cards: my moto x play doesn't like them much (I had to replace them twice before buying the sandisk; in some way the partition tables of the Samsung SD cards were damaged, plus they became read-only, resulting in two unusable cards).

which samsung model did you use? I just replaced my normal class 10 strontium card yesterday with a brand new samsung evo plus u1 card and formatted it as internal storage. so far the phone feels a bit snappy with this card.
dude search a little in this section and i hope u find the fix.i just let u know that our device has very sensitive sd pins and many users had accidentally bented them and didn't know the problem!
i hope u are not one of them!so if you are lucky,next time u put the sd be veeeery careful!i personally didn't put it out from the time i bought it...

It was just a Samsung Evo class 10. The strange thing is that I tried also a Sandisk of the same class, which gave me only the "external memory missing" problem, while the Samsung ones became just unusable plastic. But maybe I should try better Samsung SD cards.
