32 gb sdhc card problem

So I decided to upgrade my cureent 8gb sd card for a 32gb one, I bought it from amazon (with all the ebay sd card fraud rumors I decided not to take any chances) and I had install it on my phone copied my 8gbs data unto the card and suddenly after disconnected after copying data for the second time, the phone does not want to read it. It only tells me sd card ready unmount on the notification bar I try to mount on the settings it but it doesn't work, I also tried formatting it but it won't do it either on the phone. Anyone please help I really have no idea why this happen, well I think because maybe because I didn't format the sd card prior installation?

i got mine from amazon for 54 USD. works fine. so, i'd day, yeah, return it if at all possible. its defective.

I only have 4 gigabyte SD card , no money to buy 32 gigabyte

Yup yu guys were right I contacted the seller and he gave me a full refund because he admitted he had receive a batch of defective micro sd cards smh, all I say to this is, do not buy things like memories on amazon or ebay, newegg is by far much more reliable. I went on the reviews on amazon for the defective product and saw users review it as bad for the same problem I was facing.
And Trust me I tried everything to get the card to work I tried the switch on the adapter and other alternatives like formatting programs ect, it has been a pain. To all of this I'm just glad I got my refund.

Yea it was too cheap to be true, I order one from newegg for 67 dollars with free 2 day shipping from shoprunner, it was more expensive but base on the product review which none were below 4 stars, the product seems legit and not counterfiet like my previous order from amazon, I also notice that the 32 gb sign on the card I purchased @ newegg was located on a different location than the counterfiet one.

As an experienced Sd user, I would like to point out that often the reader used with the pc to format/write data to the card is at fault. With the SDHC format, you need to have the appropiate SDHC reader, otherwise corruption will occur.

Well I tried with the sdformat 3.0 program for sdhc cards and it didn't work even when the switch was away from the lock side I even put tape so it doesn't slide and it didn't work it would tell me the card is disk write protected and the windows 7 formatter would tell me windows was unable to complete format.
And what reader do you recomend for micro sd card formatting? I have one coming tomorrow and don't want this to happen again or maybe it won't because this one hopefully won't be counterfiet

[Q] help me solve this SD card issue please!

i have a 8GB kingston sd card in my tmous g2. i just bought a 16GB PNY sd card and im having troubles having it read by my computer(mac and pc) and my phone. heres what i did:
i copied all of my files from my sdcard to my computer via data cable so i could jut transfer them to my 16GB card. i put the 16 card in my card reader that came with it, into my computer and it wouldnt read it, so i tried the 8 in the same card reader of the PNY and it worked. then i tried to put the PNY card into my phone and it wouldnt recognize it. im not sure what to do.
why cant my phone or my computer read the card? its not the reader because my kingston card worked with it. is it because of the two different brands? any help would be appreciated. thanks in advance!

I had this same problem when upgrading the SD card in my HD7. I went out and got a Microcenter branded 32gig SD card and swapped it into my HD7. Worked flawlessly. A friend of mine got jealous because of the read/write performance increase, so he went out and bought the exact same thing. Only difference was that his kept locking up on him instead. He returned it and got the same exact size and brand card. After installing it, it worked just as good as mine. Turns out he just got a bad card the first time.
Sounds like the problem is in the card itself. If the PC won't even recognize it then there's probably something wrong with the card. Different brands shouldn't matter because the PNY card adapter worked fine with the Kingston 8gig card.
I'd return it if possible and get a different one.

I also just got a 16GB PNY card and I have had no problems with it reading data or having data be read off it.

Yep, I agree this is probably the issue. PNY cards are cheaply made and not great quality.

Bad SD card???

Something is fishy with our SD cards (both my wife and I), since they've somehow seemed to "go bad" about 2 weeks apart. We both have the S3 16GB and I bought two 32 GB SanDisk cards for our phones. Everything seemed fine until about 2 weeks ago when her card went out, then last night my card seems to have gone bad too. All the phone says is it's "safe to remove the card", can't access the card in any way. I currently can't find my adapter to test the micro card in my laptop, but I should at some point. Is anyone else experiencing anything like this with their SD cards?

I had a problem with my 64gb Sandisk card that went bad duing a rom flash. I have EASEUS Partition (can be downloaded free) installed on my PC and the partition on the SD card was missing. I reformated the partition using FAT32 and it has been fine now for over two weeks.
Just a note I now remove my SD card when I flash ROMs. I know it should be safe but it takes a few hours to rebuild 58gb.

This phone fried my 16gb card

What class sdhc is it?

My 64gb SanDisk errored too within the first week. Formatted and working since. Mine stopped working when I changed a battery (yes, the phone was off).

where did you buy the card? also what class is it?

I'm having the same problem with my 32gb sandisk class 4. it was working fine on my LTEVO but the moment I put it on in my GS3 the card went dead.

32GB Class 10 PNY formatted to FAT32 has been flawless for me...and I've used the same sd card in two previous devices (E4GT & Evo LTE)

Class 4 SanDisk and I bought them on Amazon. Wasn't a bulk type card without proper packaging either, it arrived in the mail packaged like what you would see in B&M's. In any case, I'm going to need to locate my adapter so I can attempt to format them.

I find it hard to believe that there is actually a "bad batch" of SD cards from SanDisk... I have a friend that also has an S3 (Verizon) that said his 32 GB card (not sure of the class) went bad as well. It would make more sense that the S3 is somehow making them bad or not recognizing them anymore. However, most of my assumptions may just be wishful thinking.

I had some problems that I think were more CM9/exFAT support related with a 64gb UHS-1 card. I used this to format it and it's been fine since

Could somoneplz tell me why I have modified status?

Iv never rooted phone at all wtf....

Do you have any root apps/files on your note 2? I don't know if right or wrong, but read that could trigger modified.

Did you disable any apps (bloatware). Not sure if that will do it, just a thought...

I just factory reset ....did the trick

I got the same thing after installing a 64GB SanDisk SDXC memory card in my phone. Take it out and put in a 32GB PNY card, it goes away. We were all told that the Galaxy Note 2 can use a 64GB microSD card but when I just checked the manual online, it says up to 32GB SD or SDHC (but not SDXC, which are usually 64GB in size and typically uses the exFat file system).

Well, I and other are using Sandisk 64GB MicroSD cards, so they do work.

I've seen other people say that, too. I'm just saying what caused the problem for me. I can repeatedly demonstrate the issue - put the card in, "modified", take the card out, "normal". Put my PNY 32GB card in, "normal". For what it's worth, the card starts out fine and the problem only shows up after I've loaded all my apps and files on to it. Both the SanDisk card and the PNY card have exactly the same contents (I can read and write to the card just fine). Believe me, I'm not trying to dispute you. This has really gotten me scratching my head....

Sounds like your phone is the culprit then.

That's possible. But IF it is my phone, maybe the OP is having a similar problem with HIS phone. That's why I posted my response, to try to help him (not jack his thread).

[Q] GS3 - micro SD problem

Hi there, I have a problem with my micro SD card, it is a Verbatim micro SD, class 4, 32gb. This morning when I woke up my phone stopped recognizing the card. I tried to restard the phone, reenter the card, put it on a different phone...nothing. Can someone help me? I haven't dropped the phone or something.

It may be a fake micro-SD card.
I faced this issue and then replaced the card with real SanDisk card.
And now everything ok.

You might be able to save a little bit of data with linux but im no expert on it.

So now, my question is, should I buy a class 10 micro sd any brand or sandisk is recommanded?

Sandisk is recommended in my opinion, but a sony SD should work just as well
