[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.

[Q] Question about SD card problem

I'm looking for some thoughts on a problem I encountered. Due to a problem with the camera, I got a refurbished phone under warranty. When I got it, I took the 8GB micro SD (not the original HTC, but a faster card from Transcend) from my old phone where it had worked flawlessly and installed it in my refurbished phone. Wouldn't mount. Put it back in the original phone; wouldn't mount. Computer wouldn't recognize it through multiple adapters/readers. Not erased or formatted, nothing would recognize it. I know crap happens sometimes. I had an old 2GB card that I installed and it worked with no problems.
I RMA'd the card back to Transcend (which is another story) who would not replace it due to a scuff mark on the edge of the card - physical damage!!!
Anyway, I ordered a new Adata card, 8GB class 10 and when it arrived, I transferred files to it on my computer (so it was working) and put it in the phone. Wouldn't mount. Put it back in the computer and no files could be seen. Ran scandisk, files reappeared. Installed back in the phone, wouldn't mount. Now it's fried, too. Computer won't recognize it anymore. Installed 2GB card back in phone and it mounts and works fine.
I've got a replacement phone coming again from TMobile - it's got to be the phone doing this. But I'm out 2 SD cards. I'll try a RMA on the Adata card to see if I can get a replacement, but I may buy another card in the meantime.
Does anybody have any thoughts on this problem? Why would the phone play nicely with the 2GB card but neither of the 8GB cards? I don't think I can do anything different, but at $15 a shot, I'm starting to hesitate buying a new card to put in the replacement phone when it gets here.
Thanks.

As a clarification, the original Transcend card was a class 6 card. The Adata was a class 10 and I read that some phones won't work with some class 10 cards...

as always, the best class to use with phones are class 4. their cheap and they work good

well, i was hesitant bout the whole "which classes will the g2 work with" situation.
i bought a pny 16gb class 10 and it works. so i dunno if its more of a this specific phone situation over an entire group of phones.

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.

If it is screwed like mine then the adapter will do nothing... my card is completely fried

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

Usb storage damaged message

I keep getting a usb storage damaged message. I have read that it is sometime an issue with the galaxy s3. Also sometimes when I first unlock the phone it says prepping sd card even though I did not remove it.
Also my SD card is a SanDisk 64gb class 10. I have read that this can be an issue with a certain crop of SanDisk.
Any tips? As of right now entitling works and if it's just messages popping up.

Have you tried using the SD card in other devices and on a computer?
I had a *similar* problem with an old MicroSD card in my original Galaxy phone and formatting the card seemed to work. I can't speak too much to your issue because the largest MicroSD card I've used is 32 and it's been flawless.

Yeah, verify across devices first. If not, try filing a claim with SanDisk if you purchased the sdcard only recently and it's already gone bye-bye.

[Q] New T-Mobile LG G3 Not Recognizing any SD card

I need help here guys,
Just bought a new LG G3 about 2 weeks ago, and i just received my new sd card ( PNY Turbo Performance 64GB High Speed MicroSDXC Class 10 UHS-1 Up to 90MB/sec) from amazon today, inserted it and nothing, i inserted my old 4gb micro sd card as well, not recognized.
I reformat the new 64GB card to Fat 32, that didn't work either.
This is the first time a micro sd card has been inserted into this phone, so could some pin inside the phone be broken or something?
Both cards work on my computer by the way, just not on the LG G 3
Any one have any idea what else i can try? Thanks

the only thing that I would suggest is get a replacement phone. If they still don't work on another G3 then there's something up with the SD

Can't , bought the phone brand new from someone, and i use it for simple mobile service, so can't be replaced thru t-mobile since i don't have an account with them. Just came from a t mobile store now and they put in another sd card to test, and nothing happens, took it for a phone repair store and they said the SD card tray needs to be replaced, for a whopping $65, oh well.

Try talking to LG before anything, being that the G3 was released in July it should still be under some kind of warranty.
