i bought a 32gb transcend micro sdhc yesterday..went home, placed it in card reader, wrote backup on it, worked fine, i could r/w on it with my laptop..then i placed it in my phone [xperia sola 6.1.1.B.1.54 stock rooted bl locked], booted it and explored it using astro and root explorer, worked fine, i could r/w on it with those apps...the problem is when i open walkman there are no songs/albums detected, so i tried exploring an album and playing it via astro and walkman was able to play the song but just the one song i selected..its also the same with sony album app there are no pictures detected from external card, so i tried viewing a pic the same way i played the song, i was able to view the one pic i selected..there are no errors popping up, which is why its so confusing..i managed to make it work last night by clearing dalvik cache, but when i woke up this morning the problem began again..any advice?

btw on stock camera app i selected external memory as save location, when i open the app it says memory error but when i take a pic it can save there as well, i took a pic and album was able to see the new pic but not the old ones..am i missing something with permissions?i already tried changing the permissions for external memory using root explorer but failed, something about sd file systems not allowing permission changes..i already formatted it countless times to fat32 still the same..it really is working fine, its just that the apps arent able to access it for some reason or another..

update: i just restored my phone with backup from 2days ago and cleared my dalvik cache..its working now..my concern is if i restart my phone im probably gonna go over everything again..this is really weird

dodgy stuff

From my own experience, I've found card readers are the culprits. Multi card readers and cheap card readers.

I now only bother to access memory cards using either my Sony Nex 5 camera, or my Samsung phone.

Sure cheap bogus SD cards can be a nightmare, but I've found it's 99% of the time the card readers. Just my own experience of going through about ten cheap multi card readers.

No counterfeits?

IDK, but half the cards I buy are counterfeits. Maybe you could mention them in case some people still have a cold ear.

Like, where to get counterfeit cards, how to "repair them" (assigning them their right size), how to address the seller, etc

Laters!

Could problem be 4.2.2?

Hello, thank you for posting on this topic. I have a T-Mobile Samsung Galaxy Note II (rooted, CyanogenMod 10.1 4/13 Nightly t0ltetmo) and a Sandisk Ultra 64gb XC1 MicroSD Card. I am running TWRP 2.5 recovery. My SD Card worked fine until I did a clean flash of AOKP Build 6, t0lte. After that, my card was no longer recognized by my phone once booted. When I try to mount the card I get "SD Card Blank or Has Unsupported Filesystem" error. My PC still reads the card with the adapter and disk management in Windows 7 shows a healthy drive (exFAT). I have run check disk with no errors. I can read and write to card in Windows, no problem. Even TWRP reads card. Only problem is once I boot into 4.2.2, card is not read. I have backed up and reformatted card as well. I thought maybe it was the Rom so I switched to Cyanogen 4.2.2 but still have same problem.

Is this a problem with the new 4.2.2 Roms not playing nice with this type of card or is there something wrong with my card?

I am thinking of going back to 4.1 but I really, really like the new JB. I am hoping I can keep the Rom and get my card to work with it. Hope I did this right. Would appreciate any help I could get. Thanks :)

** I think my card is defective. Tried putting it in a couple of other phones and it doesn't work with them either. Tried different cards on my phone and they do work. Heading to Best Buy to see if they will honor warranty or I might have to contact Sandisk directly :( Thanks anyway, guys.

About the sd of samsung

Hi everybody.

I bought a 8g samsung sd class 10 pro, for a intensive work with swapper and similar somethings... What is the time life of this sd? Samsung publicity says 10 years, but i don't believe this.

A lot of thanks for the information about the sd, some answers works for me.

Regards.
[General Accessories] ronman71:
Wow, guys. SanDisk replaced my card through warranty but my phone still won't recognize the new card. I am going to try to unroot and flash back to stock, then will report back.
[General Accessories] ronman71:
Yup. It was the new CM Roms. Reverted to stock, unrooted and card works fine. Nice of SanDisk to replace my SD card, though. Shame. I really liked CM10.

[MENTION=4797562]Deftone[/MENTION] came from the XDA portal, just wanted to add a possible solution for "Corrupt Data" issue, and perhaps others -

Possible fix for software issue (corrupt data, non-mountable file system etc.) is using a Low level format program, to format the card sector by sector and basically returning it to its factory state.

[General Accessories] hb-kevin:
I happen to work in a Sprint store as a repair tech. One thing I can definitely say has worked in fixing many micro SD cards is cleaning the contacts with denatured alcohol. It's a cleaning alcohol that is perfectly safe on electronics such as computers, motherboards, and phone parts. If all else fails, try giving the contacts a gentle scrub with some alcohol and a soft toothbrush.

Depending on which type of corruption if it is missing all it's partitions then you can fix it fully.

I managed to get mine working by doing it using a card reader since the built in one will not detect it due to the partitions.

A lot of people have sd card issue and most mite end up buying a new card.

I was too having a sandisk 8gb (w/o warranty, and i guess was duplicate) sdcard which was courrupted within 2 months, tried a lot of things but everything failed,

so i decided to buy a new sdcard,

But this time i took dual care and time before buying a new sd card and found this i.e

A card with "5" year manufacture warranty.

"5 year" is like "god" is like more than enough.

There is a company

http://www.strontium.biz/

1)Provides 5 year warrnty even on 2gb card

2)Service center are located in most of the areas of world. (Check the site for your location)

3) And price is almost same and sometimes even less than other companies.

4 )Available through most of online shopping sites (or check main site for where to buy details)

5) the product is so immune that after a rough use its working well and fine.

So all your worry about using a expensive sdcard with 10 times care would be gone away.

8GB microSDHC vs Nokia 3120 classic which support only microSD

Sandisk 8GB microSDHC versus Nokia 3120 classic which support only microSD format (up to 4GB - 2 GB and 4 GB cards use larger block sizes and may not be compatible with some host devices) >> NOT COMPATIBLE end of story.
[General Accessories] penguinjoe:
Need to add one more to your list OP. This is one that bit me in the ass the last time I tried to move to CM 10.1

Format incompatibility. CM 10.1 does not support the exFAT or NTFS filesystems required to make effective use of SDCards >32GB.

Let me explain:

SDXC MicrosSD cards now come in capacities over 64GB and, as shipped, phones like the Samsung Galaxy S4 supports them in hardware and software.

Capacities of over 32GB are very trouble-prone when using the mroe common FAT32 file system found on lower capacity SDcards. Worse, Windows absolutely refuses to format a +64GB SDCard to FAT32. Samsung (and I am sure other vendors that support 64GB SDCards) have licensed Microsoft's exFAT filesystem to legally provide support for exFAT. However CyanogenMod does not have this licensing in place and Google does nto provide blanket licensing for it.

This is a royal pain to those of us that have a 64GB SDCard in our Sammy GS4s, but want to move to SM10.1 or related rom. This leaves either reformatting your +64GB SDCard as FAT32 using a third party utility OR downsizing to a 32GB SDCard if you want to run anything except the bloated, OEM-branded, as-shipped ROM.
[General Accessories] RebDovid:
64GB SDXC MicrosSD sporadically unavailable

I have a sporadically unavailable 64GB SanDisk SDXC MicrosSD. Generally, when it becomes unavailable, that is, when the phone is unable to "see" the card or its contents, restarting the phone again makes it available. But sooner or later it again becomes unavailable.

I tried wiping the card with a microfiber cloth. When I reinserted it in my phone, it wasn't seen. Restarting the phone made it available.

My phone is a Galaxy S3 running Stockorama version2 with 4.1.2. The same problem existed, however, on my previous ROM.

It's worth a try.

Ok so this may get long winded but stay with it, it may be worth it.

I had 3 x 32gig cards 'fail' and I thought this can't be right. I noticed that sometimes when I rebooted the phone the SD would be OK and then a short time after the phone would say it couldn't see it again and it needed to be reformated. So it was intermittant. Even in the PC it would sometimes be seen and other times not. So I started to look for a pattern. The SD started out fine until I put them in the PC to transfere data files music etc. A short time after that they would start to play up and 'fail' saying they needed to be reformated when back in the phone. But as mentioned I could sometimes get them to work again. If you have exprience this type of behaviour try the following.

Keep trying to put the SD into a PC until it does read, I had to use different usb slots with an adapter but eventually they do read, then back it up. Then reformat the SD using SD Formatter 4.0 at www.sdcard.org/downloads/formatter_4

Then reload the SD with your backed up files. I had 3 x SD fail in 4 weeks. I used this method with 1 of the failed SD's and it has worked without issue for 3 months. I then did it to the other 2 SD's and have both of them running in my Note 10.1 and Acer 501. I suspect my issues were related to some structure change in the SD when I put them in the PC but I haven't had an issue since using this format tool. I don't know weather it is just pure luck but it did work for me.

Try it and see if it does help your issues, if so please just hit thanks - I would be interested to see how many had the same issues and this helped.

Thanks for reading.
[General Accessories] ftkatyowser:
I have a unique issue ("unique" meaning that I can't find anything on it anywhere, but I'm probably not looking hard enough). I have a 32gb sandisk microsd, and I was using it in my tablet for a while before it suddenly unmounted. I put it in a reader for my computer, but it doesn't mount at all- doesn't even show up in disk management. The only thing keeping me from scrapping and saying "corrupt data" is that when I put it in my tablet (galaxy tab 2 plus) it says "sd card blank or has unsupported file system" and then unmounts the card. Same thing happens if I just hit "mount sd card" in the storage menu. My s3 is in the same boat as the computer, it does not see the card at all (or is unmounting the card faster than I can see). I have a good amount of data I would like, none life-threatening but I would like to fix this card if I can.
[General Accessories] corvaxmuzzy:
It sounds like the disk has become partially corrupted. Your situation sounds like a good candidate for simple data recovery. My favourite apps are Lsoft's Active@Disk, Paragon's programs, and Easus's programs. There are also free programs, such as Recuva and PC INSPECTOR Smart Recovery. You can get them from MajorGeeks.

Hi, I have a 16GB SDCard and it show only 45MB of total space on my phone and computer and I can't format it through computer or phone, every time I click the format button on computer the sdcard unplugged automatically. Can this sdcard be repaired?

Thanks in advance
[General Accessories] DrHerTz:
You should try booting into safemode and using program "Low Level Format"

try it ...

If can't ... your SDCard is brick :D
[General Accessories] Baskhara:
Tried Low Level Format but always failed, sdcard unplugged automatically once the format button clicked, and sometimes the LLF crashed :/
[General Accessories] DrHerTz:
Did you already tried change the Adaptor of MicroSD or Change the Memory Card Reader ...

Sometimes, that can happened to your hardware ...

If you using CPU, the best way is put the USB on the Back (Onboard USB), don't trying using the Front USB

CWM restore causes corruption?

Thanks, great guide!

I'm having an as yet undocumented (or at least- not yet found) issue: After a CWM restore, my Xolo Q800 (actually, Allview P5 Quad) tells me my SD card is damaged. I'm pretty sure it is not: I ran fsck_msdos without issues, both local and on a PC (the whole card). It mounts without issues and all my files (so far) open without problems. Still, I formatted a new (32GB) card, and copied all the files (again, both via an adapter on a PC), and the new card gives the same warning..?..

I suspect there's a file somewhere causing this- but can't find any info on it. It is no problem other than that SD card warning annoys the @$# out of me, I'd like to know what's up... It is nowhere near important enough to do a full re-install (like I said, everyting seems to work fine) but I know me, and that's what I'll end up doing if I cant work out twhat's causing this...

Anyone? Thanks!

Edit: Found it was the interna SDCARD that got corrupted- its empty so formatted. Still weird that CWM restore seems to cause this (wasn't the first time)
[General Accessories] THUDUK:
I have an Xperia z, the micro sd card I used was about 6 months Old, 32GB SanDisk class 10 ultra, not been used that heavily, was put in my galaxy Note and stayed in only used to store and play music, never taken in and out, never had an issue with it until now.

Simply plugged it in the Xperia z and all WAS well, all the music showed up and played perfectly.... Excellent I thought.

Then after two days, suddenly a notification message on my Xperia sd not loaded, no file explorers would even see it, neither did the system settings.

So I tried removing the card and placing it back in, rebooting, still nothing, so removed the card and put it in the small usb card adaptor that came with the card, both my pc's I tried, nothing happened when I plugged in, yet if you go to the Computer, file explorer a grey out g drive is shown, right click properties, 0 bytes, try to format, states this is not a drive.

Tried easeus disk manager and a few other programs and the sd doesn't even show up on the list.

Now using some Old scratched up tatty unbranded. 2GB class 4 sd card, and that had been working Fine for the last 5 days.

What could have happened? What can I do now to try and recover and reformat my 32GB sd card?

Noob question

I am confused by this - I ran a search and the only 'earbud' that comes up is the kind that you listen to. I admit that I am a noob, but I did try to find it - OH! Is that another word for cotton swab?

Also, can I use 90% alcohol to clean? I have that.

I have a HTC Inspire. I took a bunch of pictures, after I looked over them, I wanted to start a file just for these particular pics. I was looking around to see how to do that when all of sudden I got the message 'Insert SD card'. The card was in and had not been removed since it was originally put in (approx 2 years ago). Now everything that was on my SD card is unacceptable. I do not know if it is gone or not. My son tried putting it into his phone and also his computer and still nothing was showing up.

Do you have any suggestions?

Thank you!​

Adapter won't load

So, I've bought a new 8 gb class 10 card on monday (3 days ago), and I've partitioned it for Swapper and tried using Link2SD to clear out some space, but I probably messed up in the proces somewhere and the Link2SD only moved apps to my internal memory again. So I went to partition it again, used the MiniTool Partition Wizard, created the three partitions but when I clicked Apply, the program said Bad Disc (or something like that) and since then my adapter won't load up the card. It works on my phone now, but it hasn't in the first 2 minutes. And I can connect the phone with the USB, too. But I need the adapter to make the partition again for the Swapper and Link2SD.

Anybody knows what's the problem here?

One more thing - If anyone thinks it's the adapter, it's not. I've tried with two different adapters, and it's still the same.

Hi there, and what is the problem with my SD card?

I'm experiencing such a weird problem with my 8gb SD card I guess.

I download a music with mp3 format and I can listen it, but after 5 minutes I can not listen the music, its not recognizing the music, it can't open it.

When I download an apk from web I can install it immediately after the download has finished, but

after 5 or more minutes I can't install the apk, it says ,, there is error parsing the package" also the icon from the apk is changed into android icon.

One more problem... when I move an app from internal memory to SD card I can open it and play it, but after 5 minutes or so after closing the app, I can not open it again, it instant force close when I'm opening. Also in settings on Manage Applications the icon on the app that has been moved to SD card is removed.

This are the problems I'm facing, every help/opinion is very apprecied.

Thanks a lot!
