Was wondering if anyone had any ideas on what I can possibly do??
The card came as EXFAT, but most roms only support FAT32.
I formatted the card to FAT32 which was fine .. but after copying a few files the card now refuses to write or delete files. I can still open and view media that's on it but that's about it. I can't even re-format it, it will say the disk can not be formated or write error. The card isn't corrupt though, I copied around 30gbs of video on it when it was in EXFAT partition before. J
I'm using an SD adaptor into my card reader, but yes I have ensured the lock switch is off.
edit - oh also, when you place the card into the phone it'll say that the card is damaged/blank.
Any help would be appreciated
Cheers,

Make sure you format it in the phone
Every time I place the card in, it will say the card is damaged or blank
Then it tries to format it but then goes through the same loop of saying it's damaged/blank

i had experienced the same problem i tried my best using several fomat tools. think almost all the tools in the world....failed and bought a new one.....think its better go for new card
Did you try to format it on Linux? I've experienced some problems with SD cards formated on Windows (assuming that you run Windows )

pretty much - there's nothing you can do. I decided to email Sandisk and here's their response:
I understand that the error that appear after format is “write protected”. First we would like to apologize for the inconvenience.
I understand that you are getting write protection error while accessing the flash drive. The flash drive has detected a potential fault and become “write protected” to prevent data loss. There is no method to fix this. You will need to back-up your data and replace the flash drive.
So you have to RMA it. I'm abit confused because others on XDA have successfully covnerted their 64gb cards to FAT32 without any issues.
Could it be a faulty batch of sd cards?.
i just my 64gb sandisk micro sd card and is having a hard time formatting it.. Whats weird popped it in the phone it recognized it but when i put it in my pic(vista) it doesnt and tells me i have to format it.. So, I put the card in my rezound popped it back out and then put it on a pc running windows 7 it recognizes it..What the hell is going on? I really need some help. I tried EaseUs program but it doesnt recognize the card..

The file format in order for the Samsung to read it must be Fat32, it's not the most efficient file partition setup, however Samsung does not read anything other than that right now, the card is probably formatted in some other type of format like NTFS. Search on the Samsung S3, using "Format SD Card", or something with SD Format in the search and you will find there are a bunch of apps for formatting the card for the Samsung.
Hope this helps

Completely untrue (it has to be FAT32 for CWM to read it, but not for the phone).
I porposefully DO NOT format my 64 gig cards to FAT32 as I have movie rips that are over 4 gigs & FAT32 will not allow over a 4 gig file size.
I have two 64 gig cards & both work fine just as they came out of the box.

so, why isnt vista recognizing my card? I also just noticed something as well..vista has started seeing the card but under computer settings it says ricoh sd device, but my other micro sd cards says secure digital storage device. I may have messed this card up popping it in and out of every device i could find..lol
update: I put it in my rezound and wiped the micro sdcard and i think thats why its saying ricoh storage device instead of secured digital storage device..If so will it harm or diminish the performance of the card?
here is how your format the ultra 64gb sdxc to fat32

Don't worry dude. I got a bad one myself. Got halfway through transferring all my data and then the card stopped transferring and hasn't worked since. Tried to nuke and boot it, HP format tool, fedora Linux, two different phones and nothing.
I just called and they are shipping me a new one. Since it will be a couple days I might mess with this one just hoping.
Edit: Something that shouldn't have changed anything. I put it in my htc rezound with amon ra, did usb toggle mode, and formatted, and it worked fine....stupid!

exfat is not compatible with cwm recovery...if you plan on running any rom other than stock, you will need to format as fat32.
Cool, thanks... I just want to make sure as to what im seeing when i pop the card in and hit format. the program is showing E:29, what exactly does that mean? It doesnt give me an option to go any higher
The phone formats the card as "basic hierarchical." not sure if it can be used with cwm

I think It may be PC related..
1. formatted it in phone which gave me 59.4gb
2. put in my gf laptop which has windows 7, then downloaded easeus and formatted the 59.4gb it gave me to fat32
3. put the card in my laptop which has vista and it asked me to format it before use(but i didnt)
4. put it in my galaxy s3 rebooted to recovery twrp and it recognize the card...
So would you say its pc related?

Hi Everyone
I bought the card mentioned below from ebay.
http://www.ebay.com.au/itm/28094386...X:IT&_trksid=p3984.m1497.l2649#ht_1906wt_1163
I have a couple of questions:
- Why is the transfer rate so slow when transferring files between computer and on to the SD card? It's like up to 2 MB/second.
- I used SDFormatter to format the card. The settings that I have used are Full Erase (Overwrite) and Flash Erase (OFF). When finished, I inserted the card and it's saying SD card damaged? I don't understand. Initially, I converted the file system from exFAT to FAT but the SDFormatter converted the file format back to exFAT.
Any help would be appreciated!
Thanks,
Sam

Hi, Thanks for your prompt response - So, since now the partition is back as ex-FAT, I would have to convert to FAT and then format the card or would it convert to FAT when I format the card in recovery?

Uhm, little question at this occassion cause I only know about FAT12, FAT16 and FAT32 (called vfat by linux when combined with long file names) so far -- what is ex-FAT?
But apart from that: formatting means writing a new file system to a block device [at least nowadays, in earlier times it could also mean write a new sector geometry on a harddisk]. So, it doesn't matter what flavour the old filesystem was.

Some of the reading that I have done with regards to these new types of SD cards from Sandisk, ex-FAT file structure is what they come with and our mobile phones are not eqipped to handle this format so hence the need to convert it to FAT. Now what ex-FAT is, I'm not sure. I'm not at my PC so will have to do some more reading on that one.
Are you sure you actually have a 64gb class 10?
There are A LOT of fakes on ebay where they take a class 2 8gb card and put a class 10 64gb label on it. Most are good enough painted on labels that you cant tell.
They even partition the card with fake info so it says its got 64gb of space....though it fills up with 8gb.
Be very careful with those ebay cards.
Anyway, that might be the reason you are getting slow transfer speeds.

Just wanted to add to this conversation, although you normally will not run into this format. Because of Windows Phone 7 on the HD2 I know about this. If the card is formated in a RAID format you will have do w low level format on the card first before you can format it fat anything. So yes rarely it does matter what "flavour" the old file system was. That it should be mentioned.

Well, I got it from a Top ebay seller so I was hoping it'd be genuine. The space on my card when I first formatted said 59gb free.
Please advise what should I do? I will let seller know and see what happens?
Thanks,
I have one other question. I have found Patition Wizard by MiniTool and if I create a partition on the card as EXT4, will our sensation recognize the card?
I have created a partition on the sd card as FAT32 but the phone is still not recognizing the card. arghhh!

Most probably you got a low classed sd card and also try formate from your phone using any compitable file manager or using the phones builtin system.
And to test your sd card, google for "h2testw" and test your memory card.

I can't format from my phone because it is not recognizing it and/or having issues with being mounted. Now, it's not even recognizing it when I put it in the adapter. The windows 7 format pop windows says 'Unavailable capacity'. I think it's ****ed Thanks, I'll search for the memory card tester.
Can someone please recommend me another one? 32/64GB. Maybe, I should get a 32GB since a lot of people are having issues with 64GB. The only reason I got 64 was that it was selling cheap. 32GB should be plenty for my needs.

I have tried using SDFormatter with the memory card reader but it always changed the file structure back to ex-FAT, which is not compatible on Sensation.
@I got 64 was that it was selling cheap:
So tell me one thing, you will drive a Mercedes but you only will pay for a small Fiat?
I have an original Samsung 64GB Class 10 sd-card with no issues. They was not cheap at all.
Things you can do is:
a low level format to be shure..
- tool: HDD Low Level Format Tool 4.25 - www.hddguru.com
- that is the tool i am using for all my memory device since years
set up a new partion and format the sd-card..
- tool: EASEUS Partition Master 9.1.0 Home Edition - Free for Home Users - www.partition-tool.com
- that tool can format every type and size
Ok that all is running on my 2nd w7 pc. Not my favor OS
When this all is not working with your sd-card, then you have possiblea a fake card.
The low-level-format tool looks deeper then your windows property.
When you have a fake card the LLF tool will stop working after it has reached the max of sectors.
You could have got one from amazon thats what I did

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?

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.

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.

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.

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

same result as i see in Gparted in linux, only 30MB, no other space anywhere
Where you able to fix it? I have a 64gb SD card that also shows as 30mb, I cant afford to lose a 64gb sd card!!
Thanks
are you sure this isn't a fake upgraded sd card? very common in the market
Same thing: 16 gb => 15 mb
