I ordered a new Sandisk 64GB SDcard but after reading many threads on the topic here, I have a question about the format. From what I've read, in order to have the card recognized by CWM and other custom recoveries, it needs to be in Fat32 format rather than exFAT. Many people have suggested that you can use a Windows based 3rd party software to properly format the card, but I don't have a SDcard reader on my PC so I'm not sure what my options are at this point. I tried searching the forums about posts from people in a similar situation (i.e no card reader on PC) but was unable to find anything. Any suggestions or ideas on what I can do to retain the full 64gb capacity and still be compatible with CWM without having access to a SDcard reader? Thanks very much.

Will need to find a PC to format it. It comes ExFat and not only recoveries won't see it but roms/kernels may not see it either. The program is guiformat. Can Google and find it easily. The site is little confusing. Click on the picture of the app and it will give you the download.

Thanks very much for the response. I was afraid that would be the case. I honestly don't know anyone who has access to a SDcard reader, so I might have to just end up returning it to Newegg for a 32gb version instead. Thanks again, I sincerely appreciate the info.

I thought these issues were exclusive to just the 64gb variants.
I actually dug around in my basement and found my old PC tower that has a built in 8 in 1 card reader that supports SDcards. If I can find a way to extract it from the old tower and hook it up to my new one, I may yet find a way. Thanks again for the continued help.

Yea. Only difference between 32 and 64 is don't need a special program for 32. Windows can do it natively. Good luck.
I realize this question may sound ridiculous, but I figured there was no harm in asking.
Is there any chance I could stick the 64gb card in my old Droid X, connect it to my PC, and then use the program you suggested to format it to FAT32? I guess I was hoping the phone could act like a SDcard reader of sorts for my PC. Thanks again.

I had a droid x but I'm not sure if it handled a 64gb but if it does you should be able to format it the way you want.I bought a $4 usb micro sd card reader for my SanDisk 64gb card and I hooked it up to my pc usb slot and used a partition program and was able to successfully format it to fat32.Have not had one problem with it being recognized by any Rom or kernel, think it gave me 59gb total after it formatted.

Thanks. I had no idea they were that cheap. If the DX idea doesn't work, I'll just stop by my local Microcenter or Best Buy and pick one up. Thanks again.
Edit: Am I correct in assuming the product linked below would do the job? If so, it's only $1.99 so I think i could manage to afford one.

Won't work from phone but go to radio shack and get cheapest one of these you can find. May be able to get with 1GB card. Take pic and show them what you want. Sorry I been busy and didn't think about it. Good call Droid. $12 max.
So I purchased a SDcard reader, hooked it up to my PC, and formatted it with the guiformat program that was recommended earlier in the thread. I set the allocation size to 65536 and left the Quick Format option checked. However, after it finished, both Windows and the S3 only show it as a 32gb card (approximately 27 GB total storage space). Is there another formatting program for Windows or any other ideas you could recommend so I can get the correct storage size (64gb)? Thanks again.

I tried using a few different programs to format the card to FAT32 but every time it still showed up as a 32gb card. I ordered it directly from Newegg so I don't think the authenticity is an issue, but I have no idea what could've caused this to happen. Regardless, I sincerely appreciate the help I got from the folks in this thread and via PM. Thanks again for your time and effort.

There's another thread detailing all the issues with exfat 64gb cards here:
http://forum.xda-developers.com/showthread.php?t=1698672
I encountered the same "hiccup" as you pertaining to the 32 gb issue.
I ended up using a program called EaseUS Partition Master to finally get all back to normal. I wiped my sdxc partition, it did come back with some message that something didn't complete ???, but then I formatted as fat 32, primary partition, and got the entire 64gb back and so far... ( fingers crossed ),.. all seems to be working well.
With the card formatted as exfat, as soon as I got around 8 gb of music, photos, etc.. the card simply would loose its' file structure and just start acting weird. All files would still show up if I pulled the card and put in an sdxc reader on the PC... but my Galaxy S3 never would recover them properly.
This has got to be some kind of "bug" in the phone as you'll see in the other thread this problem is quite common.
For what it's worth.. I seemed to have much better luck transferring large chunks of data with the card in the reader opposed to hooked up while in the phone. ( speeds kept dropping via the phone cable )
Good luck!
Thanks for the info. I actually tried the EaseUS Partition program you referred to, but it still remained at 32gb. I ended up returning the card to Newegg and will just get a 32gb to replace it as I'd rather not have to repeat this process. Thanks again for the useful info. I sincerely appreciate it.
Sure... I vaguely remember I had to try to format as NTFS first for some reason before I got it to properly format with entire 64gb fat 32. I spent countless hours trying to work out all the bugs with this card and exfat. Samsung states the Galaxy S3 phone is compatible with it... but there is definitely an issue with file structure once you start loading it up.
Quick update:
I ended up returning my Sandisk 64GB and replaced it with a G.Skill 32GB (Class 10) that was on sale for $22 from Newegg. Surprisingly, it came already formatted as FAT32 so I didn't have to mess around with it to get it working with CWM and custom kernels. Seems to be working great so far, and is plenty fast, so I'm pretty happy with the end result. I guess it might have been nice to have an extra ~30GB, but I mainly stream all my music/video anyways, so I'll have a tough time even filling up this new card.
Thanks again to everyone who gave me their advice and input on trying to get my first SDcard formatted correctly. Even though I wasn't ultimately successful, I sincerely appreciate everyone's time & effort.

Im going to pull my hair out. I finally managed to root/upgrade to cyanogenmod 10 and now i cant read my external 64gb microsd card. It use to work just fine in my stock Asus Infinity and now it doesnt. I tried using other mounting methods, but they were meant for other devices(like Evos, Galaxy, whatever). It can read other microSd cards, like 32gb and 8 gb, but i dont want my 64gb going to waste. Can someone help me and i apologize for being a pest.
I do not have my 64 GB yet -- I'm still a little wavering about ordering the Sandisk Ultra Micro SDHC Card 64GB Class 10/UHS-z as the reports of it working or not vary -- but I am curious as to how it is formatted. That might help the more knowledgeable folks out in determining the root cause. I gather it did work on stock? Can you try and reflash CROMI (after making a nandroid backup) and see if it works again?
I have a Sandisk 64GB MicroSD UHS-1 card (the red and grey one) and it works beautifully on CROMI

Works fine in both.
It use to work fine before I installed cyanogenmod10. To get it to work on the original operating system, I had to format it in my phone to create the partitions because it wouldnt recognize the card in the tablet (wouldnt let it mount or anything). I tried doing the same thing again this time and it didnt work(not allowing it to mount). Im inserting the microsd directly into the tablet.
BTW, thanks for the replies so far, I do appreciate it. Any info is useful
Sounds like a cm issue. Have you asked other cm users if they have similar issues?

No problem, that's what we're in here for. Partially...
What filesystem did you format to? Have you tried redoing it? GParted has been good to me, I don't know what system you have to your disposal to reformat. Why are you doing multiple partitions -- are you aiming for the data2sd mod? Have you tried making it a single partition? If you insert it into your phone, it does work, I gather -- if you make copy a file to the card, is it actually written?

I did a quick format on the computer, Fat32, then I formatted it in my HTC Evo 4g LTE because thats how I was able to get it to mount/read originally in my unrooted/unmodded tablet. It works on my phone no prob. As for the other questions, I think i worded my problem kind of wrong, because I wasnt trying to do any fancy kind of partitioning; i just want my sd card to work. Sorry for any confusion
EDIT!!:
So the plot thickens! After a random reboot, I was able to get the tablet to recognize the card...and then when I powered it down and backup, it lost it. It seems it randomly recognizes the card after a reboot(but not all the time). UGH!

I've had a 32 gig micro SD in my phone for a while now. I recently took my Siii out of my pocket only to find that it says the SD is unmounted. Odd, but not unheard of in the world of custom roms (paranoidkangdroid 2.something, rather recent though, 4.2.2 JB) So i do the sensible thing: Run into the storage menu, and lo and behold, its not registering. I pop it out and in, not registering. I reboot, and the damn thing still isn't registering. Then I take an old 2 GB micro SD and try it. This one worked just fine. 32 gig however does not. I move to my PC. Pop it in a micro to regular SD adapter, and the computer doesn't mount it. It does mount every other microSD of mine though. So can anyone tell me what the hell happened, and how I can recover my stuff?
Actually you can't, your sd card is corrupted and it's known to happen with this device that's why I always keep a weekly backup on my computer with everything. Especially the ones ordered from amazon the high capacity ones as far as I've seen.

Is the SD card damaged or can it just be reformatted with a card reader on a PC (fat I am assuming)?
I was about to start using an SD card to backup the internal storage. It doesn't sound like this is the best option and backing it to my PC would be better.
My set up to start was cleanrom 6.2 with envy kernel running fine for a week. I had my sd card disappear today twice. PNY class 10 32gb less than 2 weeks old from best buy. Popped it in my pc and it was recognized no problem. So I transferred my data, formatted in fat 32 popped it in phone, no problem. Transferred data back and was Ok for a few hours. Swapped my battery for a freshly charged one and upon boot, phone said the card was damaged, to reformat it. So, I pulled it out and popped it in my pc. Pc said card was damaged. I opened a command prompt and ran a chkdsk /f and it fixed an issue with the file system. I then proceeded to restore my cleanrom 6.2 backup. So far so good. I am thinking it had to do with an app, but I can't be sure. Upon googling this, it seems that some people have had an issue with external sd cards with this phone.

I'm not sure exactly what brand or model you have for your SD card or when you purchase it. However if its a SanDisk and it was purchased before December 2012 there's a chance that it was part of a bad batch. I had the exact same problem with mine I have a UHs 1 32 gig SanDisk. I read somewhere on the internet that there is a known problem with SD cards from that company built before December. When I spoke with SanDisk they confirm that and said the newer batches have been corrected. Long story short if you're using an ultra high speed or for that matter any card by SanDisk call up there customer service explain to them the problem and they will send you a brand new one. The entire process took about a week for me.

Did you try my suggestion? Ive recovered numerous files using a linux live cd and/or a mac. Try putting the card in a network printer or mem card reader if linux and mac os isnt possible. Ive recovered my files, including those from a 16gb micro sd card, using those methods in the past.
Okay, so it works
Alright alright, i didn't expect this to get many responses. Anyway, it now works. It appeared to be fried, my mac, PC, ubuntu machine, and OG droid wouldn't even recognize that a card was inserted. Nor would my GS3. My solution? after turning it on and off a few times, I just left the card in it and set it aside for an hour. Lo and behold, it now works. The SD now works. It was fried, and is now unfried. I don't know how, I just guess I am lucky. Or aliens. Either way, I am happy. Not gonna jeep anything more than music on it though... Ah well, thanks for the help XDA!
If I were you, I'd back up everything on that card to my pc, and exchange it if under warranty. If not, chuck it, and purchase another card.
Not worth taking the risk again.
Consider yourself lucky so far

The problem could be a sandisk SD card:
(Outside link) crave.cnet.co.uk/mobiles/samsung-galaxy-s3-fault-is-caused-by-sandisk-memory-cards-50010684/
I read about the SD problems after just getting the S3.. decided to get a different brand card from the store.
So I got this 64 gig Samsung SD card. the card works great in my samsung and also is read just fine by PC. whenever I put it into either my phone or my friends who has the identical same phone I get card corrupted or not supported. I'm at a loss here does anybody have any suggestions?
With the lack of developer support this would be the final nail in the coffin for this phone in my opinion.
Anybody here successfully have a 64 gig card or bigger work properly?

I've got 64GB. Works just fine now. I've had a problem writing on it. It sad that it is write protected. Which it wasn't.
I searched and found a solution. There is an app in the play store called SD card fixer (or something like that) and it says it's for kitkat (but it works on lollipop just fine). I just run it once and it was fine ever since. I did a factory reset quite a few times and never bothered to re-install the app so I'm not sure about its name anymore.

Thats a flaw that googled coded in back on kit kat.
I simply cannot get either of the 2 g flex phones to recognize the card

In my case the LG G Flex 2 is no seeing the card at all. I have a SanDisk Micro XC 64 GB. Shows a little 10 in a circle in the lower left. Formatted in ExFAT. The phone just does not register it, the icons stay muted out.
Shows fine in my laptop, and I can read and write to it, but not in the phone? Any ideas or suggestions? TIA
I have a 64 GB working just fine on mine. Just go to storage options and erase data, it should work.

Thank you. I am a recovering flashoholic. At one point I used to flash nightlies, well, daily, I am not going to root this one.
Meh. tried other SD cards; none of which worked on the Flex 2, but worked on other devices. Tried the SD card from our daughter's LG G Flex 2 which worked in hers but not mine, and she could read the one that I had bought.
Got an RMA and FedEx is taking it back to LG for their tender mercies. Had bought the thing Aug 4, received it shortly after that, Really do not need the extra memory yet, but I want it anyway,
Thanks, y'all...
Just saw the news that Modaco has released a guide on how to use ADB to enable your S7 adaptable storage! And no root required, so Samsung Pay and future Samsung update will work as intended!
Can wait to go home and try it.

I used an Evo plus 128gb and worked like a charm.

I tried this and never got it to work. Kept showing 179:0 like it wasn't seeing my sd card.
I have a 128gb Lexar high speed MicroSD i picked up from Amazon and i've had zero slow downs. I believe the SD Transfer rate is around 95mb/s so there should be zero issues with it. I did a 50/50 partition according to the guide.
Should note though - some guy says in the comments on MoDaCo's site that you can just download a terminal app and enter the commands directly. well, he's not correct. You can if you have root. Since i actually use Samsung Pay, i am not going to root this device. You need to use ADB as it states clearly in the instructions. That will work fine.
Just FYI.
Amended to say I tried just skipping to the next step, regardless of the 0, and it worked And no slow down so far
I got the same thing. Use a comma instead of the colon.

I'm frankly afraid to do that. When I ordered the phone I also ponied up for a Lexar 1800x (u3/UHS-II) 64GB card. It's expensive and really fast. It tests out in the supplied usb 3 reader on my windows pc at 175+ MB/s write speeds and somewhere in the 90's on read using winsat.
In the phone read is 68 write is 54, which I guess is telling me the sd card reader in this phone is very slow?
The internal memory tests out at 275/93
When I move apps to the sd card the boot process of the phone takes several minutes with multiple errors that all seem to be related to the incredibly slow read speeds of the sd reader. Once it's booted up it's good enough, but I don't know how adoptable storage would affect this. I guess this is probably why it's not enabled. I want to wring the necks of everyone that complained loudly that slow ad-on storage was somehow better than fast built in storage in the 6. I really would have preferred a usb c port and 128GB of internal ram to the sd reader.
Maybe someone can tell me if there's something I can do to speed the card up? Are other people seeing these kind of slow card speeds in test apps? I'm using Disk Speed Test.
I'm tempted to do this too, I just got a Samsung 128GB Pro+ which should be no problem, I might try it once I ran out of space (SOON).
Alright, I finally got a chance to format my Samsung EVO 32GB card. I followed the instruction from my original post. The only hiccup is that my SD card showed as 179,0 but I don't have any issue formating with that info.
I restarted my phone several times and I don't notice any slow down, boot issues, or slower boot up time. I haven't bother to retest my system, but I'm pretty sure the phone is slower with adaptive storage (and my card isn't the fastest out there). As for real world experience-wise, I don't feel the phone is any slower than before.
The key thing is that once you formatted SD card, make sure you go to Settings > Storage > SD card > More. Select Migrate your data. That will move your photos, music, sounds...etc to your external storage right away. Oh, and it seems like the default app storage is still internal memory. So, I have to move the app after any new app install.
Now, there are 2 issues/concerns I have. First, the total internal/external capacity that being displayed by the system is kinda of funky. I don't think the info is correct. And when you mount your phone to Windows/Mac, the external storage isn't displayed while the total storage isn't accurate either.
Second, I understand that I can't move pre-installed apps/system apps to external storage. But I'm not sure why certain user installed apps can't be move to external storage.

There appears to be an issue with your read/write speeds. Here's my test on the S7 Edge from T-Mobile. This is a Samsung 32GB card. But notice that even your built in storage is considerably slower...

OK, so one important point that "Recent Test" is not of your SD card it's of the virtual sd card that is built into the phone. So it's a test of the internal memory. To test the sd card, you have to click that red button, not the blue one. The Yellow and Green buttons both do the internal memory, just using different folder paths to the same physical storage space.
As to the faster write speeds, the tests will vary depending on what the phone is up to, and I think my result is probably slower because your storage has about 5 more gigs free. This is one of the things that made me slap my head when they announced 32 GB max in the US. As storage fills up, it slows down. 32 may be enough to squeeze most apps into, but having the ability to leave another 32 free makes things way more efficient.

I have a 128gb Lexar high speed MicroSD i picked up from Amazon and i've had zero slow downs. I believe the SD Transfer rate is around 95mb/s so there should be zero issues with it. I did a 50/50 partition according to the guide.
Should note though - some guy says in the comments on MoDaCo's site that you can just download a terminal app and enter the commands directly. well, he's not correct. You can if you have root. Since i actually use Samsung Pay, i am not going to root this device. You need to use ADB as it states clearly in the instructions. That will work fine.
Just FYI.

Have you tested the card speed inside the phone vs the max rating?
Here is mine. My SD card is the 200gb one that came with the LG V10.
