Having issues with 64 gig sd card - General Questions and Answers

I recently got this new SD card from ebay, it works great when im not using it no problems but when i try to move a file over to it it will constantly unmount itself how can i stop this?

Anyone?

What phone do you have? What is the size of file you are trying to move? Ebay is a dodgy place to buy SD cards as there are a lot of fakes ones out there! Usually hacked to give a false capacity and very low quality components used in manufacture with to-good-to-be-true prices. This could be what is causing the issue. I would recommend paying the extra for an SD card from a reputable retailer or a bit of hunting on Amazon.

Apparently after contacting the sepler the card is base dos-fat every time I try reformating to nfts it freezes the only other option is exfat which it finishs quickly but dosent change the random unmounting when transfering files.
The movies I have been able to get on there play without issue so only problem is when transferring files

Exfat is still a bit of an 'iffy' format when it comes to Android devices, I would suggest formatting the card to fat32. Windows cannot natively format anything over 32gb to fat32 so I would recommend following the tutorial here: http://forum.xda-developers.com/showthread.php?t=2041679 I have used the software in the tutorial before and it's very good. If that doesn't work then I would say more than likely it's a problem with the card.

Warnings with SD cards for A2

So I recently ordered a Sandisk Class 4 16 gb sd card for my Atrix 2. I wanted to be able to keep a backup of a ROM at all times while having 500 songs on my phone..but 2 gb just didnt cut it.
So i tried to connect the card with my phones USB cable while having it in the device, but it just wasnt showing up on the computer. I had to end up using a card reader.
It still works...just something to keep in mind while buying SD cards.

In order to view files on your sdcard on your computer, you have to select the "USB Mass Storage" option.
I did put it in the USB Mass Storage option

thats probably it. I had this happen off and on until I let android format it. my recomendation would be to put it in your computer and format it as fat32 then put it in the phone and have it format it
Thanks a lot ill try that
Although problems do not seem to be prevalent with the slower class cards, it might be a good idea to follow Patriot's advice regarding formatting. The suggestion was posted by Patriot in response to a review of a 32GB class 10 microSDHC.
Patriot acknowledged a problem with hemorrhoid OS and 32GB class 10 cards and suggested a temporary fix of performing a full format on a Windows PC with a 32kb allocation size, obviously FAT32 since stock hemorrhoid does not recognize NFTS.
The reply can be found in this review although the specific page will change if more reviews are added.

Be patient... they'll likely come sooner or later.
I got a 16gb class 4 sandisk and I am formatting it in my computer using following method:
I inserted the memory card in my E71 and connected it to my computer in mass storage mode. Then I started formatting using fat32, 32kb through my computer. But it is taking ages. Since last 2 hours, only 35% is completed. My questions:
1) Can i stop the format in between ? Or will it lead to certain faults?
2) Is the format this slow? Or should I try formatting it by putting it in adaptor and putting the adaptor in laptop slot and then format?

I'm using a Kingston 32GB Class 4 card, which is actually in my SGS3 now from my A2, and I have never seen anything to complain about with it. I still hit high benchmark scores as noted with my A2 as well as my SGS3, thinking though that I may try a higher rated class sdcard for the SGS3, since it doesn't seem to have the issues that the A2 has seen. But, a little more digging around has to be done before I make that kind of jump! (Better safe than sorry!) But, yes, the Class 10 cards will -eventually- give you grief if you try to use one with the A2. Not sure the 'scientifically-proven' answer to give here, just know that from everything I have seen, which has been substantial enough for me to believe that...

You should try a re-formatting of the sdcard, as you likely have some corrupted app data/other data that is causing the rebooting. A Class 4 card should give you no problems like this, unless you have some issues like I just mentioned.
And if you're trying to restore app data from, say, Titamium Backup, I recommend you do not do this. Just try a fresh format of the card, and do not restore data to it. Run your phone afterward for a good while to test. If your phone continues to reboot after you have tried this, changes are that you can rule out the possibility of the cause being due to the sdcard, and we can explore other possible known culprits...

And Doggcatcher has the majority of my podcast downloads failing. This has persisted after a couple reformats. Thoughts?

[Q] My phone identifies the SD card and data on it, but few things are accessible

Alright, first let me start by saying that I hope this is in the right area and i'm sorry because i'm sure this question has been asked to death.
I have a Galaxy S 3 Running stock with android 4.0.4 (Not rooted)
I also have a SanDisk Ultra 64GB SDXC class 10 MicroSD card (Formatted to FAT32)
I have had the phone a month and for probably the first week I was using the card in the ExFAT file format...Then random card identification problems started to pop up. So I scoured the web for a short time and found that the issue could be solved by reformatting the MicroSD to FAT32 at the expense of not being able to have single files larger than 4GB. Everything worked for a good week, then suddenly the phone didnt know I had music on it anymore, my player stopped and i confusedly navigated through songs that weren't there. I removed the card and reinserted and the files worked again.
Well today the phone is doing the same weirdness again, it is identifying that there is in fact a 64GB MicroSD and the amount of data is correct. It is also allowing me to navigate to the files in ASTRO, even my PC still detects and allows me to Add/Delete files from the MicroSD...BUT my phone will NOT use it. For example, if I go to camera and want to take a picture with the destination being the MicroSD, the phone says "What MicroSD?", also my media gallery is empty (Save for the files stored in the internal storage) and my music player is empty as well.
Anyway, I didn't know what course of action I should take. Does it sound like one or both of these items needs to be returned/reformatted/smashed with a hammer?

If that's the case why does it state on all the North American Cellular phone websites that the phone supports "Up to 64GB MicroSD"? Seems crazy that such a large feature could be so buggy.

The GSIII (international and US) variants do support 64 gb micro sd cards. It's advertised on the box.
It sounds like your sd card is failing you. Definitely backup all your data to a computer and think about replacing this micro sd card via manufacturer warranty.

+1. Sounds like bad card.
Ok I will try that. My next question is when I get the new sd card should I format it into the FAT32 file format?

SanDisk Ultra 64 GB microSDXC Class 10 UHS-1 Memory Card Issue

I bought this MicroSDXC card http://www.amazon.com/gp/product/B007WTAJTO/ref=oh_details_o01_s00_i00 from Amazon and every so often my microSD card will vanish. It will not show anything on the card when using Root Explorer and my music will not play and data on the card will not work. A few reboots fixes the issue but it's troublesome to reboot all the time. Sometimes it even says the card is damaged and needs to be formatted to work so I just reboot again and then it works. Anyone else having issues with this card? What can I do to remedy this problem besides rebooting all the time?
I have also experienced similar issues with the same card I got off Amazon a few weeks ago. I am tempted to reformat it from exFAT to FAT32 only issuue I would have is any video files larger than 4GB won't translate since FAT has a filesize limit If you don't have this issue I would try reformatting to FAT32 (backup your card data first) I suspect you will have no problems

It does the same thing as FAT32 so I just switched it back to exFAT.

CWM cannot read sdcards formated in exFAT, only FAT32.
If you need to format a 64 GB card in FAT32, a lot of people suggest using:
https://www.sdcard.org/downloads/formatter_3/
Maybe Samsung lied to us and the Phone can't handle 64Gb cards. Still having this issue and nothing fixes it.
I bought a 64 gb card a few weeks back when they were on sale and right out of the box I used GUIformat on my PC to format to fat32 and have never had a problem.
Maybe I'll give fat32 another chance.

It may also be that the microSD isn't that good either, and needs to be replaced. Other devices have had trouble with the 64 GB sandisk cards as well (i.e. Nook HD+ w/CM 10). But then again, the phone might just be temperamental as well.
I bought a card like this and I still can't get it to work, my computer recognizes it no problems but the phone won't, I've tried a few different formats. any suggestions?

[Q] SanDisk 64GB microSDXC

I thought the Galaxy S3 supported the 64GB sdxc card. I have been having the usual issues with it (losing communication with it in the phone but it is operational in a PC) so I wrote Samsung support and got this reply;
Thank you for your inquiry. We understand that you are having issues using the 64GB SDXC card on the Samsung Galaxy S III phone You have tried inserting the SD card on the computer without any issues, Also you mentioned that you h ave already tried formatting the Card using the phone. We do apologize for the inconvenience that these issues might have caused you.
Pleae be advise that your device lets you use a microSD™ (SD) or microSDHC card to expand available memory space. The 64GB SDXC is not comptible to be use with the Galaxy S III.
I thought they stated at one time it did support the 64GB memory.

SDHC only supports up to 32GB I am going to answer Samaung support and ask them how they support 64GB when SDHC only supports 32GB.
The Secure Digital eXtended Capacity (SDXC) format supports cards up to 2 TB (2048 GB), compared to a limit of 32 GB for SDHC cards in the SD 2.0 specification
I assure you my 64 gig sandisk sdxc card works just fine in the S3.
I kinda missed all the issues with read problems, because when I got it was before I had an S3.
When I got it, I opened the package, put the card right into my T-Mobile MyTouch 4G Slide phone, formatted the card in settings, and have been able to use it in that and the S3 fine since.
Maybe try formatting the card in another/older phone and see what happens? I was running gingerbread on it at the time.
i really depends on which file system is compatible with yer kernel. SDXC by default uses exFAT which won't read with a stock kernel. reformatting the card in your phone will format using the FAT32 File system. FAT32 is a lot more compatible but it has it's limitations like cant copy files bigger than 4 gigs.

FAT32 works and it doesn't. When I play videos it will randomly cause the phone to hang, then reboot. Not at any consistant time into the video either. But the data stays intact.

I actually came to this forum to ask about close to the same question. I'm using the first card that pops up when searching "64 gb micro sd" on amazon, and frequently (while watching videos) the phone will crash, followed by 2 vibrations, and then it boots up again.
Do you also have problems with music saved on the card? On occasion, my phone will skip tracks and will only play a few of the songs. This only happens over bluetooth (so far), and manually clicking one of the songs on my phone causes the rest to work again.
I've also been having issues with the card in general. Sometimes mine will say it's corrupt at the top, but a simple reboot or dismount fixes it.
Please let me know if you find out anything.

The only official thing that I have from Samsung is that they support 64GB micro SD cards but they do not support the microSDXC, only the SDHC. 64GB is only available in SDXC. So I think the safest way is to go 32GB SDHC. Although from reading some prople have the 64GB SDXC working but many have problems with them, including myself. Another confusion point, San Disk says it will work. I have some older flavor of 16GB card in mine now and it has been very stable.

Thinking;
Is it possible to format the 64GB SDXC with multiple partitions? Create (2) 32GB partitions formatted FAT32 each.
I used a 64 gb micro sd sdxc out of the box on CleanRom. I formatted it on accident when trying to wipe everything preparing for a different rom. Now the sd card only reads 27.4 gb. I have seen countless threads on here and google but i am not seeing a solution. Any ideas?
does the de-odexed and odexed type of rom have anything to do with if the phone recognizes exfat or fat32 sd cards?

Uhh, not necessarily. It's primarily a kernel related issue. If you're using a TW rom that comes with the official OTA kernel then you'll have "no" problems with exFat. Synergy is one TW rom that I'm aware of which comes with exFat support courtesy of a custom kernel by a dev named Ziggy. Most custom kernels don't have exFat support. You'll have better results if your TW rom includes the stock OTA kernel, the same can't be said if it comes with a custom kernel. But exFat support is not based on whether the rom is deodexed or odexed.

external sd card wont play music

Running MOAR 7.1 with ML!, not really that that matters since I had the same problem when running both stock and cleanrom.
I copy mp3 files to my external sd card (64 gb) and only the first 10 or so songs will play. All the other songs are not playable in all four different players I have on my phone. I tried reformatting drive and transferring both through the phone, straight to the sdcard with adapter, and through windows media player sync function. None worked. I also sent the card back for a replacement and same issue.
tons of different sellers selling the above card. unfortunately I was unable to post link since I am under 10 posts but the card is just the generic one off of ebay that has a blue, black, and white color scheme on the packaging.
is it just a piece of junk, does the s3 have trouble with 64 gig cards, is it something else?
please advise and thank you in advance.
Might just be the card.have u tried formating it to FAT32 so ur fone/rom can read the card properly.
Better yet see if u can format the card using the phone.

the only options through windows, when I use the adapter, are exFAT and NTFS.

Get formatfat32 software and use that to format your card. Just google and uh you should find it.

I suggest that after you format to fat32, put the card back into your phone and see if your phone can format the card, if the phone can't then something wrong with the card (compatibility or corrupted partition on the card).
I've read that the S3 just does not like 64GB cards
