It is not likely, but Flash memory does has a chance of failing even if its new, I have had a couple die on me with fairly little use... I would possibly try to contact the place you bought it (or if it came with device the manufacturer) to look into possible replacements.

Tried other computers? other card readers? If you ever get it back up for mat it and select "default allocation size" in the format dialouge. should help with future use.

Odd Issue With a Micro Sd

Hey guys this is my last place to turn before I just go buy a new one but I want to see if anyone at all can help me.
I have a Sandisk 32 GB Class 4 Micro Sd. I bought it off a guy on the xda marketplace and it was in the factory packaging and took me a half hour to get out so I doubt it was fake unless people forge the packaging.
Well the other day I went to copy a file onto the card by mounting it to the computer. It copied just fine but when I unmounted the card and went onto the phone the file was no where to be found. This was off to me so I mounted the card again and it opened fine but there was no file. I then copied it again and it said it worked like it normally does. i unmounted then mounted right away and guess what the file didn't exist.
This is where it gets interesting.
I then mount the card again and select everything and delete it all. It says it works fine. I then disconnect the card then mount it again and guess what all the files are back. Like nothing happened. I then proceed to format in windows by right clicking and hitting format. It didnt do anything. I then go into recovery on the phone and try and format it. Nothing happens. I then connect the card directly to the computer with a micro to sd card adapter that is made by sandisk. It mounts to the computer fine. I then go into Easeus Partition Manager and click format. It finishes and comes up with an error saying There are some error occurred while writing partition chains on disk.
If anyone has any idea please help.
UPDATE: I have contacted Sandisk and they are going to send me a brand new card.

Is the card detected by the mobile?
If yes, try to format it in the mobile itself with the format option.
Also check how much space it shows , before & after formatting.

Try low level format

Could be a duff card but sometimes I have had this if the card has not been fully un mounted try waiting a couple more minutes before removing the card to give the system time to fully un mount it
Or it will not be written to.

Did you press eject USB every time you pull the cable? Not doing it can corrupt your card

dont mean to sound like a **** but you do realize I posted this over two years ago right?
but anyway the card was defective so sandisk sent me a new one.

Nooooo. This is the same issue I'm having! Ugh... mine is a 64 gb and we're about to go on a long trip. I wanted to add more music. And I can't afford to buy one from the local stores. They're too expensive! :'(
I bought mine from GeekBuying.

Q) how to format FAT32 64gb card ? can't write/delete files.

Was wondering if anyone had any ideas on what I can possibly do??
The card came as EXFAT, but most roms only support FAT32.
I formatted the card to FAT32 which was fine .. but after copying a few files the card now refuses to write or delete files. I can still open and view media that's on it but that's about it. I can't even re-format it, it will say the disk can not be formated or write error. The card isn't corrupt though, I copied around 30gbs of video on it when it was in EXFAT partition before. J
I'm using an SD adaptor into my card reader, but yes I have ensured the lock switch is off.
edit - oh also, when you place the card into the phone it'll say that the card is damaged/blank.
Any help would be appreciated
Cheers,

Make sure you format it in the phone

Every time I place the card in, it will say the card is damaged or blank
Then it tries to format it but then goes through the same loop of saying it's damaged/blank

i had experienced the same problem i tried my best using several fomat tools. think almost all the tools in the world....failed and bought a new one.....think its better go for new card

Did you try to format it on Linux? I've experienced some problems with SD cards formated on Windows (assuming that you run Windows )

pretty much - there's nothing you can do. I decided to email Sandisk and here's their response:
I understand that the error that appear after format is “write protected”. First we would like to apologize for the inconvenience.
I understand that you are getting write protection error while accessing the flash drive. The flash drive has detected a potential fault and become “write protected” to prevent data loss. There is no method to fix this. You will need to back-up your data and replace the flash drive.
So you have to RMA it. I'm abit confused because others on XDA have successfully covnerted their 64gb cards to FAT32 without any issues.
Could it be a faulty batch of sd cards?.

[Q] SD Card Not Writeable?

It seems that my SD card is not writable when inserted. Is this true? I tried to create a new folder on it with root explorer (I am not rooted though) and it said that my device needs to be rooted in order to accomplish that task.
Any ideas?
Jonn

Did you try something like es file explorer? I would try that.

That didn't work either. It says "operation failed".
I actually noticed that it wasn't working playing act raiser and it wasn't saving my position. Moving the ROM to internal storage worked. I then tried to create a folder.

Huh. Just tried a different SD card and that one worked. Weird.
Sent from my Nexus 7 using Tapatalk 2

I spoke too soon. After removing the sdcard that worked and putting it back in, it no longer is writeable.
Sent from my Nexus 7 using Tapatalk 2

It works again if I pull the card out, restart the shield and put the card back in. Perhaps something up with the mounting process?
It appears that once a card is mounted, if it is removed and re-inserted, it remounts as read only.

It looks like sdcard mounting is messed up. I can't get any of the sdcards i have tried to mount.

Did you go into settings and actually click unmount before removing the SD Card? Many linux systems (android is linux) will mount devices which werent safely removed in read only mode for some bizarre reason.

I tried that as well. It still doesn't work.

when you go to storage under settings, under sd card does it show total space for card. if not maybe you have to format it to NTFS first. thats what I had to do with my new card. also said to do so on shield guide

I did not read the destructions. The destructions have useful information? Where may i find these destructions? I assumed fat32 so that is what my sd is formatted to.

sorry i cant post link yet cause im new to forum. but go there, (shield.nvidia.com/user-guide/sd-card) user guide said to format it to NTFS

Would has added this sooner, but I lost my sdcard reader.
Formatting it NTFS worked.
Still wont mount, but now i at least get the option to mount.

Yes, I formatted it to NTFS before I inserted it. It shows the total space and space available, it just doesn't allow anything to be written to it. I can take it out and put it in a PC and it works correctly. I also have another SD card that I tried and it worked for a few minutes, but I haven't been able to get it to keep working.

sorry I dont know what else to tell you, i first had the same problem like yall when I stuck in a brand new card. nothing I downloaded would go on to card. and it didnt show the amount of space left under the storage menu. Then i found out it need to be formated to NTFS. Once i did that everything started downloaded and showing up on card.

The only memory card I have gotten working (about 1 minute ago) is 512MB and formatted fat32
The card i want to us is a 16gb microsdhc formatted fat32 when this memory card is in my shield it knows it has a memory card but says it has no partitions on it.
I am running testdisk on the sd card and it found 9 partitoins. I will try and clean that up.

To be honest, I've never tried SD card support on the device. So I can't say one way or another. But I'll be looking at it soon enough since I got my first build of CWM for SHIELD waiting for me to debug in the other room once the kids go to bed.

I just tried two different 8GB class 10 transcend cards, an 8GB class 2 generic card and a 256mb sandisk card. I put each card in and copied a file from internal storage to it. Then I removed each of the cards without unmounting and put them back in and proceeded to copy a file to the card again. Every time it worked successfully. I do not even know what format they are in and didn't format them before testing. And, maybe the issue didn't show up because I didn't give it enough time. I am not sure.
Also, I know this is probably a really dumb question but the micro sd slot is spring loaded. You are pushing it in until you hear a good solid click right?

issues
Having issues of my own.
Bought a 64gb sandisk SDXC card for shield. It worked 100% fine in my SGS3 formated for exFat. But not in the shield...
It seems to work somewhat when formated for NTFS. But the file path is really messed up and 1/2 my apps cant see the SD card because of this. It something like (root/storage/sdcard1/....)
2 apps that are basically usless right now due to this are Power amp & FPse.

Android doesn't normally support either exFat or NTFS. The shield may include support for them but if I had a shield I would steer clear anyway and go with what android definitely trusts in FAT32.
Hopefully NVidia will do a firmware update to sort these problems though

[Q] sd card not detected anywhere

Hi,
I have a samsung galaxy note 2 and i bought a cheap micro sd card from ebay which was a big mistake. the card is 64 gb and i bought it a month ago. it was working fine until yesterday. i got a notification saying safe to remove sd card.i went into storage settings and it says mount sd card. when i mounted it,i got another notification saying blank card and then it asks to format the card. i took the card out and did the same procedure several times but the same thing. i've got important data on the card and have no other backup. i also used the usb cable to connect it to the computer but it only recognizes the phone memory and not the card. i dont have a card reader. i have checked several threads here on xda but i cant find anything related to my problem. please help me....please its really important. thanks.
