Rooted and now can't write to external SD card - help! - Shield Q&A

I rooted successfully and got directory bind. Everything is lined up perfectly and I press add and nothing happens. I then go into the sd card via my pc and I try to create a folder and the PC won't allow me. I suspect the card can't be written to which is why directory bind won't copy. Any suggestions? Before I rooted, I had no issue creating a folder on the SD card....

I should mention I also d/l the sdfix kitkat program from google play and it says no action necessary.....I also can take the sd card out of the shield and plug it directly into my pc and it works fine so it;'s def shield related
The current format is NTFS. I've been reading FAT32 could be an option but I'm using a 32 gb card so am I going to lose half my card? Don't understand why I had no writing issue prior to root and now I do? both were NTFS
FIGURED IT OUT - FAT32 was the answer. works now formatted that way. not sure why ntfs all of a sudden stopped working after root.

so shield can't write on NTFS either.. ?
I knew it can't handle exfat, that's just meh..

that actually wasn't the problem, he ran the app but it was already modified.
NTFS was the problem as the shield only supports it as read only.

Trouble with 64gb SD card

Anyone have this card http://www.amazon.com/gp/aw/d/B007W...-5410429?ref_=pe_175190_21431760_M3T1_SC_dp_1 or any 64gb SD card? I'm having a problem getting cwm to recognize it. I already reformatted it and still it does not work in cwm. Anyone know anything about this? My 32gb card works just fine

Try formatting on a Mac. I have that card, tried three PCs with no luck but works perfectly after formatting on Mac using FAT.

I guess cwm does not support exfat which the gs3 defaults to when formatting 64gb cards. I found out here http://forums.androidcentral.com/sp...ting-roms-hacks/184708-64gb-micro-sd-cwm.html I need to partition the card with a program. I'll do that tomorrow I'm going to bed lol

One of those "believe it or not" things: the SDXC (SD eXtended Capacity = 64GB or more) specification says that the default (factory) format is exFAT. The GS3 recognizes both exFAT and FAT32, but some ROMS do not support exFAT due to Microsoft's funky licensing.

You don't need to partition it. You need to format it to Fat32 as was mentioned.
I am now on my 3rd 64GB MicroSD, the same one in OP.
It works when I get it, but it preformatted as exFat, which wont work with ROM.
The first 2 SDs I used EaseUS Partition to format as Fat32. Format went fine, but when I went to place files on card, card unmounted. This last one I used Ridgecorp’s Fat32Format, but same problem.
When I insert card, Win7 sees it, but if I go to format/write it disconnects.
Before I send this third one back to amazon, any ideas how to format it?
FYI, I took the last one to a frien with a mac to see if he could fix it, after i tried to format Fat32, but no luck.

Yea, I believe that's the same card I have(had for working on 3 1/2 months now) and I used the Ridgecorp GUI utility in this thread, http://forum.xda-developers.com/showthread.php?t=1773735 to format it as soon as I got it.
I've loaded it with music and continue to play said music all the time, use my ext for all my ROM downloading and storage. I access it all the time thru the phone and computer with no problems attributed to the card. (Some ROMs screw with my computer seeing my phone period)
Surprise! TW UI Did the trick!
S'up Crew
I don't know if this would apply to anyone on this thread but I bought a SanDisk 64GB MicroSDXC and my SGS3 Wouldn't recognize the card and all.
At the time I was running CM10 Stable.
After trying several different methods found around the forums (both here and external) nothing worked.
W7 would only recognize it as a 32GB because of OS limitations and with every single third party software I tried it was always the same thing (32GB only).
So on a whim I decided to try a slightly different approach.
I flashed a backup I had of the Original Touch Whiz UI I had laying around back onto the device. Shoved the SD card into it and LO and BEHOLD.. It recognized the card.. Erased the Contents and Formated it properly!
I went into Titanium Backup to see if it actually worked and there it was..
63.xGB.. Woohoo!
So apparently CM has problems seeing a 64GB MircoSDXC correctly and the Stock Touch Whiz UI OS works nicely to see it and format it.
Hope this helps the next person who reads this!
I formatted my 64GB class 10 card in my Mac to fat32 and it has worked fine since.

[Q] SD Card Not Writeable?

It seems that my SD card is not writable when inserted. Is this true? I tried to create a new folder on it with root explorer (I am not rooted though) and it said that my device needs to be rooted in order to accomplish that task.
Any ideas?
Jonn
Did you try something like es file explorer? I would try that.
That didn't work either. It says "operation failed".
I actually noticed that it wasn't working playing act raiser and it wasn't saving my position. Moving the ROM to internal storage worked. I then tried to create a folder.

Huh. Just tried a different SD card and that one worked. Weird.
Sent from my Nexus 7 using Tapatalk 2
I spoke too soon. After removing the sdcard that worked and putting it back in, it no longer is writeable.
Sent from my Nexus 7 using Tapatalk 2
It works again if I pull the card out, restart the shield and put the card back in. Perhaps something up with the mounting process?
It appears that once a card is mounted, if it is removed and re-inserted, it remounts as read only.
Jonn

It looks like sdcard mounting is messed up. I can't get any of the sdcards i have tried to mount.
Did you go into settings and actually click unmount before removing the SD Card? Many linux systems (android is linux) will mount devices which werent safely removed in read only mode for some bizarre reason.
I tried that as well. It still doesn't work.

when you go to storage under settings, under sd card does it show total space for card. if not maybe you have to format it to NTFS first. thats what I had to do with my new card. also said to do so on shield guide

Yes, I formatted it to NTFS before I inserted it. It shows the total space and space available, it just doesn't allow anything to be written to it. I can take it out and put it in a PC and it works correctly. I also have another SD card that I tried and it worked for a few minutes, but I haven't been able to get it to keep working.

sorry I dont know what else to tell you, i first had the same problem like yall when I stuck in a brand new card. nothing I downloaded would go on to card. and it didnt show the amount of space left under the storage menu. Then i found out it need to be formated to NTFS. Once i did that everything started downloaded and showing up on card.

The only memory card I have gotten working (about 1 minute ago) is 512MB and formatted fat32
The card i want to us is a 16gb microsdhc formatted fat32 when this memory card is in my shield it knows it has a memory card but says it has no partitions on it.
I am running testdisk on the sd card and it found 9 partitoins. I will try and clean that up.
To be honest, I've never tried SD card support on the device. So I can't say one way or another. But I'll be looking at it soon enough since I got my first build of CWM for SHIELD waiting for me to debug in the other room once the kids go to bed.
I just tried two different 8GB class 10 transcend cards, an 8GB class 2 generic card and a 256mb sandisk card. I put each card in and copied a file from internal storage to it. Then I removed each of the cards without unmounting and put them back in and proceeded to copy a file to the card again. Every time it worked successfully. I do not even know what format they are in and didn't format them before testing. And, maybe the issue didn't show up because I didn't give it enough time. I am not sure.
Also, I know this is probably a really dumb question but the micro sd slot is spring loaded. You are pushing it in until you hear a good solid click right?
issues
Having issues of my own.
Bought a 64gb sandisk SDXC card for shield. It worked 100% fine in my SGS3 formated for exFat. But not in the shield...
It seems to work somewhat when formated for NTFS. But the file path is really messed up and 1/2 my apps cant see the SD card because of this. It something like (root/storage/sdcard1/....)
2 apps that are basically usless right now due to this are Power amp & FPse.
Android doesn't normally support either exFat or NTFS. The shield may include support for them but if I had a shield I would steer clear anyway and go with what android definitely trusts in FAT32.
Hopefully NVidia will do a firmware update to sort these problems though

Big problem with 128GB SD Card

Hello everyone, i am having a serious problem with my 128GB SD card. I have formatted it on my Shield before using it, but i can't move apps or files to the SD Card. It usally gives a error message. What should i do? Format it with a Linux Distro using GParted on the PC? Should i format it to FAT32 or NTFS? I'm out of ideas.
Thanks.

Mine works fine in FAT32, but would not work in Exfat or NTFS. I am still on 4.2 OS though.
I forgot to say i am using 4.4.2, OTA Update 77.
Also, it is suggested that exFAT with 2048 cluster size would work for 64GB cards. Is it a good idea to do this on a 128GB card?

It's because of Kitkat. You must install "SDFix: Kitkat Writable Micro SD" in Playstore to have the permission to write SD card. You need root access for that.

I can see my card and even play my DVD's off of it via VLC (MX Player isn't 5.0 ready), but I can't change files. Does Android's "Erase SD Card" option also format? I may try that as I don't have anything else that can read/format a 64GB microSD (well, my DSLR can but I have no microSD to SD adapters)

what format is your sd card? Nvidia recommends NTFS, not exFAT, so before trashing the card try to repartition it to NTFS format through Windows system tools
