Help S3 Eating Micro SD Card

I dunno what's up with my phone, but it's eating micro SD cards like it's cool. I had a 16g card I reused from my DX when I bought the S3 and it went bad during use. Had everything backed up so while it was a PITA, I didn't really lose anything.

I bought a new SanDisk Ultra 32g micro SDHC card and copied all my files to it (that was about a month ago). Tonight, I was moving some MP3s from my phones internal storage to the SD card when after about 25 MP3s, I get a message stating that my device is no longer connected. WTF! So, I double check and my phone has an "exclamation point" saying I have to reinsert my card. I do, and now my phone won't recognize a card's been inserted. I took it out, plugged it into my PC and while it shows up in Explorer, it has no files nor can I format it. Fried!

What's up with this? I can't keep buying SD cards left and right. Any thoughts? Thanks...
 
Where did you by the card? My gut is telling me it might be bogus. I think Crystal disk mark can tell you if it's real.

I'm not sure I know what "Crystal disk mark" is. I purchased the card from a reputable seller on eBay. It came in a SanDisk blister pack and looked as legit as if I'd bought it from Best Buy or similar type store.
 
I also had this happen. Put my Sandisk 16gb card that I used in my Dinc, into my phone when I got it, reformatted and was using it. Randomly one day prolly a month ago, I got the same message. Tried fixing it with various programs on my computer that, after running them, allowed my computer to see the card but my phone could never write to it. Have been using the free 2gb card I could with my Dinc since with no issues so far.

Also, my message just popped randomly. I was not using the phone at the time (was at work) and just checked it for something and saw the message.
 
Maybe the card reader in ur gs3 is faulty. But to be sure of that go out to a local store and buy an sd card. Ebay sellers can be tricky thesedays no matter what rating they have.
 
There have been so many issues with bogus cards bought via eBay, but this usually surfaces immediately, in that the cards report the expected size, but then turn out to have much less than the expected capacity, resulting in them being unable to store anything like the number of files that the user expected.

I've only ever bought my memory cards from reputable sellers (and I've never been sure whether I could trust all my local stores), and I've found that Amazon is comprehensive and competitive - but only if the card is supplied and shipped by Amazon.

Having said all that, I had a card fail in my old HTC Desire HD, as did many others. I have no idea why micro SDHC cards should be so unreliable, but failures such as you've described aren't, sadly, that uncommon.
 
I'd like to thank everyone for their comments. The funny thing is that when the card failed, I was updating all of my files so that "if" my card failed again, it wouldn't be such a PITA to recover. LOL... life can be ironic at times.
 
Gonna try this one more time. Stopped by BestBuy and bought a 16g PNY SDHC Class 10. Let's see how long this one lasts. If it doesn't work... I'm jumping ship to a Razr Maxx HD. Not liking the radios in the S3 anyway.
 
The "problem" is this piece-of-junk S3 -- NOT the SD cards!

Mine already burned up one SD card -- and fried its internal file system in the process.

Then a few days ago, my wife's S3 wouldn't mount her SD card anymore -- completely trashed the filesystem on the card. Have tried four different data recovery apps against the card and they all find NOTHING.

These are different brand cards, NOT purchased off e-bay, and both from companies known for making memory cards.
