A few months ago, I purchased a 32 GB Class 10 Micro SD card. It went bad a few days ago and I cannot get anything to read it.
The issue is this: because I have no sd card inside my phone, I can't take pictures, listen to music, etc. However, I recall doing something to make my micro sd card the primary storage, where before it was the internal sd card that stored all the pictures and music.
What can I do to revert to making the internal sd card the primary storage location for all my files?
Thanks for any help.
What kind of phone do you have?

Hello everyone.
I have this strange things going on with my microSD card.
Recentely i bought 32 GB card for my nexus one (using cyanogen mod 7)
When i use that card on my pc i can write all the files at 5 MB/s speed. Then i put it inside my phone and it doesn't mount. After few tries like 4 or 5 it mounts but after that some files are gone from sd card. Allways leaving like 30 GB of empty space. So if i write more it will delete some so it would be 30 GB. Then it mounts normally.
Ok now more then half of you will say that this is fake card or smth. But i downloaded H2testw program and checked my card. Everything is fine with it. The program wrote 32 GB of data and verified everything. Its just problems with phone reading SD card. Anyone can help me ?
Hmm........
So noone has any ideas ?
Check your phone for firmware updates that might raise it to the 32 gb ceiling. Maybe there is a Cyanogen 7 update that will take care of this for you. Also does your phone support SDHC cards?
SD Card Not reading correctly
If you haven't done so, you might want to check the specs of your device to ensure that it will accept 32GB. Some devices top out at 8 and 16GB respectively.

That, and I would upgrade to the latest nightly of CM7.
It is probably not "32gb" "Genuine" memory card.
I've purchased the memory card couple months back and
It says "16gb" when I put musics/videos in the memory card, it was unreadable and unplayable. I think it had actual memory of "2gb", so yes, I've been scammed by Chinese people =P.
I recommend you to check your actual memory by using this program
"H2testw"
When I play video stored on my internal storage, it is smooth. I can watch a 90 minute movie video without noticing any glitch at all.
When I play video stored on my external storage, there are glitches. One glitch every 1-2 minutes. These are not big glitches, just a brief deviation that gets your attention. If I listen, I think it is skipping a fraction of a second of the audio. (It may be skipping a fraction or second of the video display also, but my eye doesn't detect it). It's not a huge deal: ...... but just something that I notice and it's a minor irritation.
Since it occurs only on external sd, not internal storage, I assume it is the speed of the sd card. I have a 16GB Sandisk SD card. If I remember right, it's "Class 6"
I don't hear any glitches when listening to MP3's off of external sd, works just fine with no glitch ever.
SUMMARY: no problems on internal sd, no problems on mp3's. The only problems are videos on external sd.
It seems to me that the external sd can't quite keep up with the high transfer rate required for video playback.
Has anyone else seen this?
Any observation about which SD cards do this and which don't?
By the way I'm running rooted 2.3.6 from qkster's package, with Zen's Infusion A kernel. Holo launcher.
I haven't tried boosting to 1600Mhz. I'll try that and report the results later.

I just tried it - no difference. Glitches still occurred with cpu max frequency set to 1600.
You should try to format your external card and then try again.
Also, it could be your external card is to slow on reading
Should not be that slow if it is class 6 though...
Maybe try other card on your infuse with same video file.

Thanks. I have also noted the SD card media scanner runs to scan my external sd card more frequently... almost every time the phone comes out of sleep. I think this symptom coincides with me adding more files to my external SD.
I will try reformatting now as you recommended.
Question: is it better to reformat sd card in the phone or on the pc?
(if on the phone, there is no question of file system... I'll let the phone pick the format. If on pc, I'm not sure what format to pick... I'm using Entropy's kernel with voodoo lagfix enabled... does that mean external cannot be formatted to FAT32? )
The bigger problem is the constant scanning every time I turn the screen on. It was a nuisance, and I think it was draining my battery.
It gave the error message "sd card unexpectedly removed".
There are threads on this for some other Samsung devices.

There was a suggestion Sandisk cards in Samsung devices tend to have the problem.
I transferred my files to my pc, formatted sd in the phone, no problem until I transferred files back... then problem started recurring.
I reformatted in the PC to Fat32. Put files back on. Seems to be much better. But very close monitoring using SD Card Monitor program....

... shows it is still have problems. I'm going to break down and buy another sd card. Perhaps another brand.

Your SD card has problem for sure.
It shouldn't scan that often and it shouldn't say it is unexpectedly removed.
Seems either phone's card reader or the card is very unstable. That is why you are having problems in video files.
If the SD card benchmark program shows that tour SD card is performing bad, I beehive you got fake Sandisk SD card or really low class SD card.
From this point, I believe getting new SD card is the best solution here.
PS. You should put the SD card on PC then run benchmark on PC to see how it performs on PC. If it performs too much faster on PC, then the problem might be your phone's card reader.

Symptom went away with new sd
Before replacing the sd card, I had 100+ sd card events recorded by theSD Card Monitor program in a 24 hours period.
After replacing the sd card, I have 0 events recorded by the SD Card Monitor program in a 24-hour period.
The new SD is a Lexar 32GB Class 10 for $45 at Target. (preformatted as FAT32)
It was cheaper than the $70 32GB SanDisk they're selling at Best Buy.
I'm tempted to say the problem is solved.
On the other hand, one thing I noticed on the old SD was that the old sd symptoms got worse with time... I don't think they were there when the card was new. So I'm not sure if I've really solved the problem or just reset the clock waiting for the new SD to act up under whatever influences degraded the old one. Time will tell. For the time being, life is good. That scanning upon coming out of sleep was a real PITA.. slowed down the phone just when you picked it up to use it... actually dropped two phone calls recieved while phone was sleeping.. I presume because the phone wasn't able to handle scanning and answering at the same time.
Perhaps it was a fake SanDisk. Where'd you buy it from? Lots of fakes on eBay.
I bought the SanDisk (that had the problems) at Best Buy.
Ever since I got the M8 i've been having issues with the camera storage to SD card. I am now rooted and running a custom rom, but still experience the same issue. I have the Camera photo files saved to Ext SD card. I can take the photos and it will save fine to the sd card. after a few hours though when I navigate back to the gallery, the photo's will show up as a cached file/missing (Triangle w/ exclamation mark). This was happening on stock unrooted rom. I rooted hopefully fixing this issue but it still happens. I even formated the SD card in the phone and it made no difference. I'm running the latest Skyfall rom. Any suggestions for fixing this other than saving the photos to the internal phone storage would be appreciated.

Im having the same problem. Maybe we can help each other out. Mine is a 64gb class 10 i got off of Amazon. I formatted it every way possible both in a computer and in the phone. I just swapped to an older 32gb ive had for a while and see if I still have problems

Yeah, that was my next plan. I too have a 64GB Samsung class10 card. The phone is supposed to support up to 128GB storage. Let me know how it goes. I will try the same. :good:

Update:
I havent any problems with pics since switching to my 32gb card
I changed my SD card to 32GB and it is working fine now to. Now I can save the photo's to the SD card without it deleting them. sucks that my 64GB card wouldn't work properly. I used the same 64GB card in my Experia Tablet Z and it works fine, saving pics or transferring data. Of course I'm running 4.2.2 on the tablet.
I had the same issues with mine, I had a Trancend 64 Gig from Amazon and switched to a Sandisk 64 Gig I had laying around and its fine now. Both my Trancend cards seemed to have the issue with this phone but not with my Samsung devices.
Just as the title says, I am having random unmounts and remounts of my sd card when trying to download things and when trying to view gallery. Phone is not rooted, its a sprint variant, and it's a 64 GB ultra sd card. I have had this card since my note 3 and it has given me no issues up until now. Am I the only one? Is there a fix for this? It's been doing this since day one.
Sounds like it could be a bad sd card. Try getting a adapter and putting it in your computer. If it reads it back everything up and format the card.
I've had a few micro sd cards crap out on me in the past.
I had the same problem. Never had a problem worth the cardin the previous phone. Format the card in the phone, still does it get a new card. And buy a Samsung micro sd. I have had numerous SanDisk cards die and finally went to Samsung and never had a problem since.

My phone never rebooted, I have a 128 GB SanDisk Class 10 sd card. But after like a few weeks or months I got a sd card error and soon after that I couldn't access any files on it.
Only rebooting solved the issue, but once I got it it would occur more often and often, sometimes every 2 days and sometimes multiple times a day. Formating the SD card made it work again for a few months until it started all over again.
I formated it to different formats (in windows), I also formatted it with the phone itself, nothing helped.. I'm constantly running out of space now because I only store my music and photos on the sd card.
I never tried a different sd card long enough to recreate the problem, but I used this sd card for a few months on a different device.
If someone fixed this please help me I'm so tired of this :crying:
I have a 128Gb Sandisk in my Mate 7, runs with no issues at all. Maybe clean your contacts?

To be honest I never tried it lol, but if rebooting the phone solves the issue I don't understand how dust or dirt could be the problem. I will try it anyways, maybe it works :cyclops:

Cleaned the sd card and the sd card slot as good as possible, but after a few days I had the same problem again... Maybe my sd card is broken but I can't really test it so I guess I'll live with this forever...
Just now it came to my mind that I could've bought a fake SanDisk card, even though I got it from amazon. I will test it tomorrow I think.
Maybe.
How is it formatted? Probably most compatible to format to FAT32.
I have a 64Gb card in an old phone that was supposed to take a maximum of 32Gb and it works fine when formatted the right way.

It is formatted exFat right now, I formatted it quite a few times since i got the card so I don't know whether I always had exFat or not. I'm checking the SD card now for it's real capacity, with 100 GB left it will take 8 hours, but if it's really a fake card it should cause errors way earlier I think. If that's not the problem I'll wait until I have time to flash KangVIP, then I'll re-format the sd card and do some cleanup while I'm at it.
i bought a 128gb samsung evo+ sdcard and working great so far
