Help with formatting issue on Sandisk 16gb micro sd hc

Well first off I want to apologize for such a lame first thread, but I've been a heavy reader for a while now and this is the first time I haven't been able to solve it.
I bought a Sandisk 16gb micro sdhc class 2 card for my fuze and having a very difficult time formatting it.
I put it in my phone, connected it to my comp via usb and selected "disk drive" option on my phone, then on my comp selected the "open folder to view files" option and I put some files on it. I then disconnected it from my comp and a few minutes later checked to see if my files were on my phone, the files were there but it said the card was full when there was only ~1.2gigs on it. So I connected it back to my computer and when I tried to open the card it said that the card was not formatted, so I select the format now option and it will fail, saying windows could not complete formatting. I then downloaded the panasonic sd formatter from www.sdcard.com and tried formatting again and it says the write protection switch is on and to turn it off, well there isnt a write protection switch on the card...
So I'm not sure what to do at this point, can anyone offer any insight to this issue?
Thanks in advance for any help.

There is a write protection switch on the SD adapter

well in my case the "sd adapter" is my fuze/tp which has never had any problems serving as a disk drive adapter for my sd card in the past.
my laptop has a slot for memory cards and i do have a micro>sd apadter but my lt can not read sd hc cards.

no one can help or offer any insight?
I really don't want to have to buy another one..
I would be willing to donate to whoever can help me fix this..

SanDisk microSDHC card
I did move the write protection switch both ways and it still says write protected in either direction. please help. Thanks

i think it may be your version of windows. i had a similar problem even with a 4gb non-sdhc sd card. it can be read on the phone, but for some reason can't be read if put in the laptop. i just didn't format it because i know it worked.
when i bought a 16gb micro sd for my touch pro, funnily the laptop recognised it even with an adaptor. so maybe since i updated my windows vista, it also updated 'the driver' for the card?
sorry more anecdotal than anything else. just try to use windows update - if you use windows.it may help as in my case.

did u solved the problem???
i have the same problem
i can see the files from the card but i cant delete/copy/format (

the card may be a fake. registration does not actually authenticate the card. where were these cards purchased? if ebay or some similar site you should probably contact sandisk support to verify authenticity 866-sandisk

I have a same problem. Although it is a Transcend disc 16GB class 2. No, I didn't buy it on ebay. I am using Windows 7 x64. Copying to the card can happen when it is in the phone mounted.

same exact freaking problem

ok i'm having this same problem with a sandisk 8gb card... It's very annoying as i can read but basiaclly cannot write anything to it or format it. How was this problem solved?

still no solution?

im dealing with the same issue i have a 16g sd that came with my d1 and now my pc reads 14g from my phone then 31mb from a flash reader??

Thank you this thread has helped!
You asked for more info and I would recommend two free programs:
1) H2testw 1.4 which tests to see if your card has genuine capacity
2) SD Formatter for SDHC This software formats all SD memory cards, SDHC memory cards,

Check my last post on the thread I quoted - you are probably using SD slot on PC. Try USB. What card were you using.

[Q] [Pro] Problem with new microSD card

I've just bought a brand new 32GB Class 10 microSDHC card from SanDisk, but I'm having terrible trouble with it in my Xperia Pro.
The symptoms are that, if I move apps to SD (using the built-in method in Gingerbread), they will start force-closing. Files stored on the SD card sometimes won't copy from one folder to another. The terminal shows "I/O errors". Eventually the SD card will seem to disappear completely from the system. Sometimes the whole device will spontaneously reboot.
If I put back in the original 8GB Class 4 card, everything works fine.
I am sure the 32GB card is genuine and it works fine on a PC (tested with h2testw). I have tried re-formatting it in both a PC (using Windows and Linux, and using native OS methods with various cluster sizes and with the SD Card Association app) and in the device. However I format it makes no difference.
I haven't yet tried a different ROM on my Xperia Pro (I'm using stock Gingerbread at the moment, although I have rooted it).
Do you think a different ROM might help? Or is it just that this card isn't compatible with the Xperia?

Default [Q] [Pro] Problem with new microSD card
:crying: Hi see you have tried the re-formatting option this is good because first thing people start suggesting is re-format option lol.There can be a number of things wrong and I have seen many post's with same problem as you(and after trying lots of options it does boil down to a faulty card) Even when the card as been tested.Not saying that is your problem but it is strange your old card works and also this being a new card so untested on other phones etc.It would be good if you could test on another phone although this can be unpractical I know everyone as not got a spare phone.
Also as you suggest could be the rom follow the link below this might help
Try this option link http://forum.xda-developers.com/showthread.php?t=1010807 it may help:good:
With regards to moving apps to SD card I have always found using the app link to SD the best solution for me it as never let me down.Only thing with that you need to partition your card with minitool but it is well worth it because you can link apps with widgets without any problems.
Just a few suggestions maybe some others have some too:good:

[Q] SD card not letting me add or delete files

I've been spending waaay to much time trying to get this phone to work as I had expected with previous phones (even my LG G2x) giving me less problems. I recently bought a Sandisk 32gb, class 10 micro sd card and after transferring old music, pictures and videos from my old LG G2x with a 16gb card, placing files from my computer back onto my S4 with the 32gb card is a nightmare! Photos are transferred but too out of order to try and deal with although it's more the music problem that has me bugging. I have some success after putting about 3gb or so onto the new*32gb sd card but after that, the sd card flips out and starts using special characters for file names. Below I attached a screenshot of what I'm going through with another app called V1 Golf for Android. I'm stuck and any help is much appreciated. I can't delete anything on my sd card nor can I add. I've reformatted this card about 4 times now without success. Some say that a Sandisk have been nothing but problems for them, you think a Samsung card could be the fix?
I'm also running windows 7 on my computer as some people have said that could interfere with the transfer but it seems like that's not the problem being that downloading apps from google play shows corrupted files depicted below.

First, did you format this 32gb sdcard using fat32, exFAT or NTFS or ?
If you did not format it with fat32 then that could have caused the problem.
First you need to remove the card from the phone and plug it into your
computer using the adaptor which came with the microsd card so it can be
tested and repaired in windows.
Once the card is plugged into the computer and it's recognized by windows make note of the drive letter.
Then open a cmd prompt in windows by going to the start menu clicking on RUN then type "CMD" and click OK to open the DOS prompt.
Then in the black DOS window type: chkdsk E: /F then press "enter" to scan and fix errors on your microsd card.
NOTE: The E: is just an example, check the actual drive letter of the sdcard which is plugged into the computer.
Please note, doing the above will not delete any files or folders unless they are deemed unusable and cannot be fixed.
The chkdsk will NOT not format your microsd card.
Good luck!

Unfortunately I ran into a very similar situation with a 64gb SanDisk card. After several months of using it successfully without issue, out of nowhere some 20 gigs of data were stuck. It seems that 1 file in a nandroid was corrupt. After formatting, re-partitioning, deleting etc, etc. with Windows 7 as well as MiniTool Partition Wizard I was unable to ever get the corrupt file to delete. Thus leaving the $60+ card useless and a prime candidate for the trash. I chalked it up too a "bizarre" instance. I have since purchased 2 64gb cards, one to replace and one for my new S4. Haven't had the issue since (knock on wood). Not sure what the exact culprit was, the recovery? (TWRP), a freak occurrance? or Just a defective card? If you have any luck saving your card please post how you did. Although I realize this probably isn't helpful except to know your not the only one.

My sd card seems to be stuck.
About 20 of 64 gb being used.
Now I can't delete anything. Or add anything.
It appears to delete and then it just comes back.
Does that mean my sd card is dead.

scandisk 64gb
Had the same thing just happen to me. Transferred a few kernel files yesterday and today couldn't delete, add or format anything. I was able to copy all files to computer but that's it.

same thing happen to my sandisk 64gb class 10 microsdcard as well
is it a virus?

I had the exact same issue with a San-disk 64gb micro sdcard, I contacted San-disk, they offered me a replacement card.I suggest you do the same, hopefully they will exchange it for you.

You can use another SD card to try whether this sd card is dead.
If anothe SD card can delete files, it proves that this sd card is dead, vice versa.

Did your problem solve? I'm experiencing now like with your problem. And I'm looking for an answer.

[Q] tab pro can save to some sd cards only

Hi guys.
let me say first that I am aware of whole writing/permission issue with KitKat.
And I am happy to use the build in file manager to copy stuff around.
But as I had some issues with my sd card(files were copied then dissapear etc) I bought Samsung! Sd card Class10 32GB and to this card i am not able to write at all!
I can format, create a folder but that's about it. Not able to copy anything using the 'internal' file manager.
Everything works fine if I can connect the card via OTG.
Any ideas? As i am stacked now with 2 SD cards I cannot use.
And btw with all this write restriction explanations. Why I cannot write to internal card slot only?! If it is OTG I can do anything with any application. Somehow all the explanations I have read do not add up in this part.
Any enlightment highly appreciated.
Cheers

Sounds to me like you bought a counterfeit /fake MicroSDCard , if you purchased it off ebay then chances are it's a fake. the packaging looks identical to real Samsung products and it is very hard to tell the difference.
Do you have a card reader for your pc, you can do a test on it to tell if its fake, there are several programs that can do this but the most popular is H2testw .
Take a look at these threads for more info

http://forum.xda-developers.com/general/accessories/fake-samsung-evo-64gb-micro-sd-cards-t2852818
The issue you are describing where files just disappear is a telltale sign of these fake or counterfeit cards, usually the cards only have about 2GB of writable space and the rest is bad memory.
Btw on a side note: I have no problems on my tab pro 8.4 , I have every single GB of my Sandisk 64gb sdcard filled. and have no problems with it..

SD card issue non root

Known issue with 4.4.4 on Verizon Note 4? Any good work around? Even if I use a native app such as "my files" it doesn't delete files or folders. Pics taken with SD card location are lost with default camera. I can't seem to write anything to SD card. Even if I male the change on laptop removing the SD card from phone, as soon as I put it back in phone the directories are back. I've also tried non native apps. Nothing seems to work. My SD card appears useless at the moment. (64gb card)

Is it a Sandisk 64gb? If it is then I read a post in the S5 forum from a guy that is having a similar issue you are have, which I gather from your post, is that you can neither read nor write anything to your SD card. According the other guy he spoke to Sandisk and it's a bad batch of cards that radomly lock themselves and can't be unlocked.

I have the same problem with a Samsung Evo sd card. Transfer stuff onto it and it's gone when I look for later. They really killed android for me with this sd card lockdown. I liked my rooted note 3 without kitkat much better.

it is a sandisk 64 - the phone can read the data on it (pics, icons, apps (emulators/roms) but it will not write anything new to it
i have tried formatting it in every OS - the card is locked - i haven't taken the time to test an alternative card because most of my older ones 2gb, 8gb were also sandisk.
