[Q] external memory card problem - AT&T Samsung Galaxy S II Skyrocket SGH-I727

My ext. Card (32gb sandisk ultra micro SD) constantly corrupts random files. I don't think it is the card because this is the third card I've used with the same results. I can however use the card on my laptop and it works perfectly fine via the card adapter. If I put music or movies on the card from the laptop and try to use it on my phone the file won't work or works for a few seconds then stops. Also, when I save to my phones internal memory it works fine. Has anyone else had issue? I've tried factory resets and custom ROMs but its always the same result. ANY input would be greatly appreciated.

Don't install custom ROMs on top of each other.

Tried it and it didnt help. I tried putting some files on my phones ext sdcard via usb cable from my laptop but it freezes in mid transfer. Also when I tried to make a Backup with CWM it wouldnt complete. So i wiped/formatted and fresh installed stock rom again and installed TWRP with the same results. I think its time to just give up. Also when I try and install SUPER USER it gets stuck in a boot loop. Frustrating.

ideas anyone
Okay I was able to flash cm10.1.2 and super user with twrp. Its crazy I can transfer media to the internal storage just fine but not to the SD card. I've factory reset with twrp and reinstalled stock and nothing seems to fix this.

I'm so glad someone has posted this issue, I can confirm it does exist on stock Rogers RUXUMA ROM with an external Sandisk 64GB class 10 card.
The problem especially occurs when downloading compressed files from the internet. They appear fine but when you try to extract them, they have CRC failures. Sometimes they are fine until you reboot the phone.
I have been trying to troubleshoot this issue for months, its a problem with MTP or exFat on this particular phone. I've tried both CWM and TWRP, no success. The old Gingerbread ROM which didn't have MTP or exFAT support works fine, I've gone back and tried dozens of times.
I'm just surprised nobody else has reported this.

I could really use a hand with this pickle

okay, so i've found myself in a bit of a pickle. Recently I've been running the CM7 nightly's, but today I tried out the RoyalGinger rom and I believe it either corrupted my SD card or it's blocking my SD card from being used/read.
Tried several times to reformat it but each time it said 'checking SD card', but the weird thing is I have an active wireless connection, but I'm not getting texts. I can download from market, get on Facebook, etc, but my texts won't come in until I reboot the phone. A few times I booted it up and it wouldn't allow me to even see my homescreen because it'd pop up with EVERY app force closing (including google services, framework, etc), I was able to get back to my homescreen by clearing by Dalvik Cache luckily, however I'm still unable to do most anything. I went in to wipe/restore but it says cannot find SD card, directory invalid, cannot mount, etc.
Is there a way to reformat my SD card through terminal? If so could I get the code procedure for it? or anyone have any ideas other than picking up a new micro (which isn't a big deal but I'm strapped on money til Friday) but i'd still prefer to know that it's JUST my SD card and not my phone memory. Anyone? Anyone? Beuler? Beuler? Thanks in advance. I'm really sorry if I posted this in the wrong section, but c'mon, everyone gets one.
Ok so do u have a stock backup rom? Ide say go to rom manager and go to recovery and whipe etc.. Then install that stock back on it.....And can ur sd card even read at all? Just get any.file manager and check your sd.

I think I have a backup rom of CM6, but not an actual android stock rom. It won't allow me because it says 'must have an SD card inserted' then it says must have clockwork mod recovery installed, which I do, the current version. Now that it says that I'm afraid to boot my phone into recovery, and I can't really tell if my SD card will read. I was able to use my file manager and the entire SD folder is blank.
ten minutes later: still boots into recovery, none of my backups are available on it. I was thinking about downloading a rom from the phone and trying that way, but I don't know if it'd save to the (apparently unreadable) SD card.
Ok try this...... Find out what recovery you use 3.0.0.5 or the normal 2.5.1.4 for froyo then download a rom thats the same recovery as the one u have on it right now...... If its the same as your cyanogenmod 6 then install that from the recovery manually!!!
if its not then download a rom that is and make sure you use a file manager to see if the download sticks in your sdcard. And if it doesnt stick then......your problem sir might be a corrupted sdcard, or a phone that cant read your sd.
Hope its not either or, so give it a shot.....
And ur supposed to have a stock backup as soon as you root and switch roms man Lol makes life easier

It sounds like he doesn't have access to his sdcard. It doesn't matter how many backups you make if that's the case...
If you happen to have a sdcard reader or a microsd usb adapter you could format it in windows, copy the files you need, and start again. Also did you try connecting to your pc and seeing if it's readable that way? You can format the card if your pc recognizes it. If you have adb set up you can push the recovery image to the phone without a sdcard. But once again without a working sdcard you won't be able to flash a new rom.
Hey guys I'm pretty sure it's just my SD card. I tried saving an image, just to test it and it says 'an SD card is required to download images.bin', so I'm HOPING it's just my SD Card, however my notifications are working properly so I can at least deal with it til friday, if it IS my SD card reader in the phone, well... I have a plan for that, however due to already technically breaking that I shouldn't go into it. Thanks to you guys for taking the time to post and if you know anything else that might help me I'd gladly accept it.

Hi, I have a reader on my laptop but not the adapter, so I can't tell and yes, you were right, I can't see any of my backups (which I have my stock, then cm6 and cm7) so I either need to find an adapter or get a new SD card. luckily I pulled all of my camera images off my phone last night when I put the new rom .zip on the phone sd, so I'm not really worried about 'losing' anything as long as I get my phone working back in proper condition.
Well that happened to me before as well.. All i did was replace sd cards lets the phone do its thing flash a different rom like CM6 or CM7 and then once replaced i got the adapter for my old sd card reformatted through windows and put it right back in and it worked.. So try that?
Ill have to. Thanks a lot guys I do appreciate any comments and suggestions and ill be picking up a new sd later thia week to fix it but can amyone recommend a good brand sd to pick up? the apparently failed one was a samsung 8gb

Hp is very good, u probably can find one with 8 gb. At best buy.. But if u want a 32 gb then thats online all day

I usually use sandisk so yeah try that?
Something similar happened to me. Your SD card likely has a bad or corrupted file. I used Win7 to copy over what I could to a folder in my PC. The Win7 automatically refused to copy over the corrupted files while carrying over everything else. In XP, your file transfer stops and you have to try again to ensure you have everything that's not corrupted transferred over.
After copying, I just went ahead and formatted the SD to FAT32, transferred everything back, installed on my phone, and voila.
Go into recovery and partition the card. You'll lose everything on it but it should be useable after that

MHX Superlite 5.0 mediascanner

I flashed the MHX Superlite 4.5 yesterday. Media scanner "starts" whenever I open gallery or music or any app that accesses media. Songs/pictures on my external SD card would not be recognized by either stock music player,play music,gallery
I flashed MHX Superlite 5.0 today. The problem persists. I searched the thread and found that someone suggested to run "SUPERIPE" then reflash.........I'm assuming they meant Superwipe. I ran Superwipe TWICE, re flashed and still no change.
Fortunately there is no stick when restarting or shutting down, but I could live with that.............Need my music
Thanks
Update: I have tried a new ROM AND a new sd card and the problem persists!
how big is your media stick? brand?

sounds like you might have filesystem problems with the sd card? i suggest you copy all your stuff off it using the mount usb storage option in cwm (mounts and storage > usb), and then format /sdcard under cwm, or remove the card, format it under a windows computer, and reinsert it.
formatted the sd card (while connected to my PC and using the default FAT32 setting)
problem persists

I've had pretty good luck doing the following to fix strange errors:
Wipe data
Format system twice
Format data twice
Format cache twice
Run superwipe
Flash rom
Wipe cache and dalvik before first boot (this requires holding the volume buttons on the superlite 5 install at the appropriate time)
I'm sure this method is at least 50% superstition on my part, but it works for me every time.
I just want to state for anyone who ever reads this
I finally got the media scanner to work
Method
flashed through Odin original skyrocket leak
Flashed cwm
Ran super wipe
Flash ROM

I had the same problem, with a different ROM. I think there was something corrupt or messed up on the internal sd card, cuz after I moved everything to the computer, it worked fine. The one click worked because it wipes the emmc. I went straight from GB to a ICS rom, that's why I had a problem.

I woke up and found that somehow my wall paper had reset itself, and the media scanner was not working again. Thanks to what you said, I knew to format the Emmc and media scanner works again.
I did remove everything from the SD card to my PC and format the card a few days earlier but that didn't solve the problem.
It seems you understand what's going on. Could you explain a little more. I rather understand than just know to format emmc
Thanks
To be quite honest, I'm not 100% sure what causes media scanner to lock up. From what I read elsewhere on the internet, it could be a corrupt file, or maybe its just that ICS's media scanner handles files differently than GB's media scanner. I'm leaning more toward the latter, as GB media scanner never had a problem when running a GB ROM, and there is some reason as to why the one click ICS was designed to wipe the emmc (internal sd card).
Hope that helps clear any confusion!

[Q] Flashed 1st Rom, everything good, Then accidentally formatted internal sd

So I finally got the courage to flash a rom after dealing with an extremely sluggish Vibrant for over a year. I flashed the rom and everything was good, then I tried to get all my music on the phone. I couldn't get it on the external 16gb sd card so I figured I needed to format the card. I went into settings and It only gave me the option to format one of them, under SD card "format" wasn't even selectable. So I format the one I could and now notice a lot of missing folders. All that is left is albumthumbs, android, dcim, lost.dir, external_sd.
I'm not sure what I deleted but the phone still works fine.
What do you recommend I do? Should I odin back to stock and then load it again?
U should flash rom again

Thanks for the response. That is what I figured.
Flash ROM again OR attempt recovery using a recovery tool

You could also connect your phone into mass storage mode to the computer and attempt a recovery using one of the many available tools if you had important information on the internal SD.

SDCard Mounting Errors with microsd inserted.

Hi, hoping for some help. I am running PAC-rom (latest nightly) and am encountering the following situation.
My phone and internal memory (sdcard0) works fine without a microsd plugged in.
As soon as I plug in any Microsd (tried a 32gb and 4gb and 8gb) the phone loads the contents of the microsd (external and sdcard1 I believe), but then sdcard0 does not get mounted.
Seems it only wants to run one or the other. I have tried searching and came across ideas of formatting etc, but nothing seems to get them to work together. Has anyone else encountered this? Any ideas?
Let me know if any additional information is required to troubleshoot.
Thanks!
Sounds like a software fluke ... Try falling back to the latest stock ROM ucmc1 via Odin and perform cleanup ... Wipe and factory reset. Then do a clean install if your favorite custom ROM following their installation directions from their xda page.

I haven't gone to stock but have the issue on the latest CM as well as PACman.
I guess a better question would be whether anyone running these roms DOES NOT have the issue?

Problems after Rebooting

After doing a hard reboot, there is a 50% chance the phone will soft reboot again within 5 minutes if I don't clear the cache/dalvik. After doing a soft reboot, my SD card is not recognized and then I have to hard reboot... You see my problem. Do you have any suggestions on what to do so I don't have to clear my cache/dalvik every time I need to reboot? Thanks!
I am running CM 13 Nightlies
Try to reboot your Phone without your SD Card. Maybe your SD is faulty. If your Phone is working ok without SD, then Backup your Data on your SD in PC, format it to FAT32 and try again to reboot with SD Card.
Sorry I forgot to mention Im using my SD card as adoptable storage. Am I able to still format is as FAT32 and also use it as adoptable?

You can still try rebooting your phone without the SD card to test it. Some of the apps may not appear but that's about it. Be sure and turn your phone off before removing or inserting the SD card. I would suggest using the phone to change the card back to a removable media card before putting it in the PC to format.
Just a few questions before I do anything. Will reformating my SD card wipe all its data? Can a FAT32 formatted SD card be used as adoptable storage? Will a FAT32 formatted card be able to have a swapfile on it? I use a ram expander

Yes, formatting the SD card will wipe all data on the card.
No, a FAT32 card cannot be used as adopted storage, only a card adopted by the device can be, that process formats the file system as an encrypted ext4 system.
Maybe, but I'm not sure Android normally use a swap file, so you might have to make some manual changes which would be overwritten every time you flash a nightly build.
TBH, the RAM Expander is probably your whole problem, the low processing power and I/O speeds of the device plus using an SD card are probably causing delayed writes and extreme lag and cache corruption. You should have at least a UHS3 card, even then I would suspect the RAM Expander is the root cause of your problems.

Ive had this rebooting problem shortly after i flashed CM and didnt get the ram expander for a few weeks after that. Ideally, I wouldnt have to flash another ROM.

Try another rom then... CM is hardly the only option, and some devices do better with different ROMs.
Otherwise, give us something concrete like a logcat or something.

Ok I'll upload a logcat as soon as I get it to break again.
Here is a logcat I got. I'm not sure if I caught the first failed reboot but it soft rebooted a good 3-4 times so hopefully there's something worth looking at. Thanks for your help!
BTW - it's in a zip because it's exceeds the file limitations for .txt files on xda.

I did a quick glance though the file, I'm at work and will look through it more later, but two things stuck out to me... there seems to be a lot of package errors, and the theme is not happy.
When is the last time you did a clean install, and then reinstalled your apps from the Play Store (not restored from TB or similar app)? Also, does the problem still occur when you use default theme?

I did a clean install about a week ago (and reinstalled my apps from the Play Store). I haven't tried it with the default theme but I can do that this afternoon.
Just rebooted with the default theme and it booted up fine but then i rebooted with my previous theme and it also booted up ok so basically idk if its the theme yet.

Update: Im fairly certain it was the theme now. I have since replaced it and my phone is much more stable. Thanks for your help! Now whenever I reboot, it will probably soft reboot once and then it works fine.
