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.

I had a Kingston 8GB Micro SD SDHC which worked perfectly on my Kaiser. But after losing it, I ended up buying a replacement on ebay and the transference speed is incredible slow. I copied 1.5 MB of pictures, and it took like 10 seconds; 3 songs took like 5 minutes, maybe more.
Do SDHC cards need to be formatted in a certain way, or do they need something to make it work faster? I want to be sure before sending it back for a refund.
Note. I used the card reader and the USB adapter, I haven't even put it in my Kaiser, so they problem can't be related to the phone.

Do you know what the class speed of the new card is? The class speed is the transfer rate of the card.
Class 2 = 2mb/sec
Class 4 = 4mb/sec
Class 6 = 6mb/sec
Thanks, but even if it were the slowest class, isn't 5 minutes for 3 songs, too slow? The songs were like 3mb each.
I would agree that yes it is slow. I also wouldn't set those transfer rates in stone.
Are you sure the card you bought is original ?
Because there are so many fake memory card on ebay and personaly i wouldn't trus ebay for buy memory card
maybe formating the card with an other cluster size helps...
ebay scammed me twice for memory, once with a sandisk cruzer and another with a sony pro duo. they rebrand oem ****ty ones with the casing and sell it for double the amount. be careful man. you might want to defrag it too, that will help tramendously. also, turn off encryption if youre on wm6.1 pro. encryption makes reading anything a drag.
Not to steal your thread, but didnt want 2 threads on similiar topics.
I'm looking to buy an 8GB micro sd card. What class should I buy: 2,4, or 6? Also what brand: Sandisk or Kingston?
Buy the fastest you can get but not if 6 is double the cost of 4. Brand doesn't matter in my opinion because Kingston and Sandsik are both good. I had a Kingston and now i have a Sandisk.

If you have warranty and not satisfied you can always change it, if not try reformating on a PC
Good luck,
Thanks for all your answers. I learned my lesson, never get a micro card from ebay, let alone from one of those Hong Kong sellers. I tried to reformat the card and it took hours. Contacting the seller took days and now they want me to send them the card so the can send me a replacement card instead of a refund.
Right now Newegg is selling a class 6 8GB micro card for $16.00: link but it's just the card and from A-DATA (?). I bought a Kingston card from newegg also ($20.00) and that one works great.
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.
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

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
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.

Them cards tend to go out very fast and randomly. I only buy sandisk cards cause' there the only ones that seem to last forever with me.Only thing you can do is get a new card, that cards dead
That card last for over an year than, but my most concerning question is, can I somehow save the data from it?

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
32GB UHS-1. I can't get mine to work, whether formatted fat32 or ntfs via PC. Tablet 8.4 simply doesn't recognize it.
My older sandisk 32GB class 4 disk works just fine.
Anyone else have issues with the UHS rated cards?

According to SanDisk it should be supported fine
http://pct1.sandisk.com/ProductList.aspx?DeviceID=21309
I would check if it's a counterfeit / fake card usually these are sold on eBay, Aliexpress or even some marketplace sellers on Amazon/wherever, some even leak into the retail sites, they look identical packagewise and design wise (sometimes it might have blury paint job, or typos on the packaging) ...
To check if it's fake there is various software for the pc (like H2TESTW or chkflsh ) that will write all the blocks on the card and tell you if it's fake..
btw I have a Sandisk UHS-1 64GB card and it works fine. so chances are you got either a counterfeit or a dud.
Though you could just have a card that went bad, I have had several SanDisk micro sdcards fail (one just went poof, nothing-dead, the other went to read only mode), my card had a lifetime warranty and SanDisk has been great with sending replacements. (you will need a camera to take a close up, (so you can read the serial number on the back of the card)-if you choose to RMA and it's legit)
My Sandisk UHS-1 MicroSD that works fine on my Tab Pro 8.4.
NTFS, while a Windows favorite, can be problematic with Android devices. exFAT is pretty much standard nowadays (especially now that larger capacity cards are common - not supported by FAT32), although the old reliable FAT32 should work fine for 32GB.
Try formatting exFAT on your PC, or formatting on the tablet.
Otherwise you may have a counterfeit (tons of them on eBay as mentioned in the previous response) or simply a defective card.
Android never even had it listed as a device, so even kicking a format via CLI wasn't an option.
Everything tests ok on the PC, but something clearly isn't right. Back it goes.
Found the SDSDQX-032G-A46A for $20 at BestBuy, as well as the SDSDQX-064G-A46A for $40.
I print them both out from the website and drive to the store - where we pull up the website and the pricing has changed back to $80 & $150.. They wouldn't honor the printouts. What a great company. Google cache still has the original price, but the site changed in the time it took me to drive to the store.

try the formatter located here
https://www.sdcard.org/downloads/formatter_4/
are you running an official firmware on the tab pro?
But you are right, even with a bad filesystem it should prompt you to format it - strange, if you have root access you can check dmesg or logcat in terminal to see what's happening when you insert the card.
I did try that formatting utility.
dmesg shows nothing applicable, and logcat does absolutely nothing when that SD is inserted. When putting in my old SD card I get the typical flurry of activity of detecting, mounting, etc.
I bought a Samsung Pro+ 32GB card and that didn't work either. Clean flashed the final CM12 snapshot, still doesn't like either card. Old card (Sandisk class 4) continues to work fine.
Absolutely nothing in logcat for either of the U3 cards. It is as if nothing is being inserted into the tablet at all.
I'm ssh'd into the tablet. No new devices show @ /dev/block with the new cards. Old one has the expected mmcblk1 and mmcblk1p1.
I have Samsung Evo+ 64GB(for model not sure, but Samsung) and it has 95MB/s reading and 90MB/s writing speed and my 8.4 WiFi detected it. But it doesn't fully use those limits(what i want to say is that my SD card has very fast writing speed but when I uploaded 100MB file to the card, it took about 5 seconds to do that) and I don't know is that SD card broken or tablet is bad.,

I had this happen to me, unfortunately the only way you can fix this, is to give it back to Sandisk (RMA), for replacement. Since your current Card is as they say, pining for the fjords. The good news is that SanDisk support their Cards for up to 10 Years. Which meant more (to me.), when I had spent over 60€'s for it. Today however, you can replace this Card for nearly a Tenner. If anything I can only praise SanDisk's RMA Dept. for being both courteous, and prompt. I think I had to wait a day (or so), to get the confirmation oder. And, likely Six weeks or so for the Return. It was like two years ago now. Thankfully this New Card hasn't died on me in that time. That first Card, though dies on me like six months, after I bought it. The Representative I spoke with, mentioned that a bad batch of Cards had managed to get though, at the time, and that it wouldn't be an issue to just send the dead card back for a new Retail Package. MicroSD + FullSD Adapter.

First of I doubt, those Tools would be of very much help, if the Card is in fact now dead. When my card died that was it Windows, Linux Phone, or Phablet the Card was non-existant! However the Card should have a Serial Number printed on the Back. (So break out the magnifying glass!), perhaps the tracking was what took the most time before I finally got confirmation.
Just outta interest has anyone tried to shove a 128GB into the Tab-Pro 8.4 to see if it goes?
