Gold card SD card brand/model compatibility.

So here's my problem. As far as i can tell i am reproducing the steps to create
a gold card to the letter. However after spending close to £30 on SD cards and
getting nowhere I'm pretty much either the most unlucky S.O.B on the planet
or I'm doing it wrong, which i really don't think i am at all, I am very methodical
and re-trace my steps two, sometimes three times.
If i am just unlucky, there must be a way to tell if a card is capable of
becoming a gold card. What exactly are the requirements for a Micro SD card
to retain the HEX'd info without failing to mount? It can't be random chance
that every time i click 'save' then exit from HXD my pc/phone refuses to read
the card as a mountable, formatted file system.
another thing I've noticed is that the Information you write over in OFFSETs
01 (or whatever it is) to 170 are replicated in the second block just after it.
Is that a security back up of the CID security check on the card? because
I can't see why the card would have it twice if it had no intention of using it.
I'm probably wrong about that but It was worth mentioning.
Really my question is what EXACT make and model number has worked for
people? If enough people post in this thread with the data I will make a database
that i will maintain for people who; like myself are having serious problems
finacially getting a gold card sorted out.
So please post as follows:
Manufacturer: blah blah
Model: ohh blah
Model Number: sdsdsd
Batch Number: sdwe23e
Don't worry if there is missing information. Just post as much as you can.
If there is more or different information than i posted please post that also.
Thanks.
Confirmed working:
transcend 8gb class 6 card
ScanDisk Mobile Ultra 8GB

i got it working with a transcend 8gb class 6 card
http://www.amazon.co.uk/Transcend-microSDHC-Memory-adapter-TS8GUSDHC6/dp/B001IAMME8
didnt work first 4-5 times tho
kept trying and it worked
i would suggest instead of buying soo many cards, you keep trying

So you format the card in phone.
Take the card out, into the PC reader.
HEX edit and save.
Remove.
Boot phone with the card in.
And if it fails, repeat?
Also, noted the make and model of your card, thanks.

eh i didnt have a sd card reader at the time so i edited the stuff via sd card in the phone

I've heard it works either way.
When you have edited the card and it's in the phone, can the phone read it
or does it come up as blank?
Also, in the quides where it says "reboot with card inserted" does that mean the boot console
or a normal boot? Sorry for the 101 questions btw.

It works with the stock SD card that come with the phone. Your best of having a card reader and plugging it into the pc to edit certain parts. Just do exactly as you say and you will be fine.

I have a tmobile hero also and my problem is the fact that the goldcard bit seems to work and my pc can read the card, but when following the tutorials and doing the backups, it fails, i hate tmobile
ah and Im using a ScanDisk Mobile Ultra 8GB, tried it with the stock 2GB and same problem

Same here,... SD card that came with handset worked fine.
Initially failed when using Windows 7 64bit but was fine with an old XP machine.

Hmmm i've had the same problems on 2 Kingston microSD 2GB cards, the whole procedure was fine but when it comes to the testing, when i tried opening the drive, they said i needed to reformat the card. Hmmm are there any sequences of steps on how to do it or so?

wORKS FOR ME!!
Thank you so much!

Also make sure you are choosign the right option when opening disk...I think its logical (but not sure as im not on my pc) i tried on many cards using the removable disk option and it didnt work, then on a whim i tried the other option and it worked first time!

dude your the man ive tried 4 cards about a hundred times with no luck but never tried the other option (think it was physical disk) and it work first time

I did it with two different SD cards and it always worked on the first time. I did it with a card reader.
- SanDisk 2GB (HC)
- Sandisk 8GB (HC)

I've tried it with:
4gb Lexar
2gb PNY
2gb SanDisk
2gb Kingston
Using these steps:
wiki.cyanogenmod[dot]com/wiki/Howto:_Create_a_Goldcard (I'm not special enough to post links I guess...)
No luck at all with any of them.
Any pointers would be nice as I too would like to not have to purchase more and more SD cards to get it to work...

ok, I think I got the gold card right, but I wasn't able to use it to root the phone...
Either I didn't actually make a gold card, or the phone is just a real pain...

[Q] Microsd card not being recognised.

The 8gb card that came with my Desire HD works perfectly as you expect. But i wanted to upgrade so i bought a class 4 Kingston 16gb microsd card.
So i unmount the card, take it out, then put the new one in... and when i go to storage management it has unknown for everything. When i take the card out the OS says "Card removed, insert new one", i put the old one in and it works perfectly.
I then reformatted with windows and made it 16kb fat32 and the exact same thing happens.
The card works perfectly on the computer and is not an ebay fake.
Any suggestions?
Edit- i just loaded up CWM and it easily saw my sd card. So i dont know whats going on there. I partitioned it using CWM and now am installing a different rom and hopefully the problem will be fixed without me even knowing what the issue was.
Still any suggestions will be appreciated.

Most of the steps you took, make sense to me, but I am not an expert on this.
One question, can you let all of us know what the result was, after you flashed a different ROM? Might help someone with similar issues.

My S4 (GT-19505) cannot read SD cards (SD card blank)

Hi XDA Family.
I recently flashed Omega Rom on my Galaxy S4 and everything went well. The next day I played my music from my SD card then there was an error "cant play this music file or something like this" after that my S4 was displaying that my SD card is blank or has unsupported files. The phone recommended that I need to format it using the phone. I formatted it like my phone said but it did nothing. Phone still displaying that SD card is blank or has unsupported files.
The next day bought a new SD card (8gb Scandisk) and the phone read it no problem. I transferred all my music to my new SD card and after playing my music the error appeared again and now both SD cards are showing that the SD cards are blank or has unsupported files.
Re flashed stock rom and stock kernel but still has the same errors on my SD card
Borrowed a memory card reader from a friend and formatted the SD card using my PC formatted it with all know file system. FAT32, exfat and NTFS but everything is not working.
Lastly I tried my SD cards with another Galaxy s4 and they worked without problems, formatted it using the phones formatting capability inserted it on my S4 but still has the same errors.
Any suggestions are greatly appreciated guys.
Thanks in advance.

Any help would be greatly appriciated.

I have The same problem.
Pls help

Hi! Thanks for replying, I was beginning to lose hope that anybody would reply. Tried your suggestion. Downloaded 3 scanning SD card apps on Playstore but none of them worked. Both of my SD card still shows up as blank in my S4.
This only happened after i flashed a ROM, anything I still need to do to go back to stock? Already flashed an official softwas and kernel.

Hi Good Morning!
Tried that last night still the same problem. Tried the chkdsk on CMD still the same problem. I can buy another SD card but I am just afraid that maybe a week or two the sd card will mulfunction again and I cant forget the fact that my PC and other S4 can read my SD cards.

Two possible reasons. Sandisk SD cards supposedly fail easily but yours is 8gb so it should be ok.
Next reason is Omega Rom bug, I personally don't have this issue but I have a similar one. My Sdcard does not mount as r/w automatically.

Thanks for the reply lamstone, I have read somewhere that disabling the automount helps. Can you help me on how to disable automount? and can I do it if I am on stock firmware?
Thanks

Just use the card reader and adapter and attach it to your computer and format the card using exFAT file system. Then use it in phone. AFAIK the current custom recoveries already support exFAT. So you should be fine for anything. I had similar issue with my 32GB Sandisk Ultra card when I formated it using phone. No issues since I formated it as exFAT on PC.

Hi thanks for the reply.
Tried Fat32, Exfat and ntfs and all of the still has the same error. Actually bought a new 16gb sd card earlier I popped it in my s4 and still has the same problem.
This started happening when I flashed Omega rom. Is there anyhow I can check if I have a stock everything? My kernel, recovery and firmware?
thanks for the patience.

BUMP!!!
Anybody who can help me??
Another update is that I installed CWM recovery Philz Edition and tried hooking it up on the UBS cable and mount usb storage. My computer can now see my sd card inserted on my phone. Tried reformat while my phone is on CWM and connected thru USB cable and formatting goes thru but phone still says SD Card is blank or has unsupported files.
One thing that is strange though is that when I try to copy things to my SD card while my phone is attached to the USB cable my PC freezes like it cant copy any files to my SD card.
Any help would be greatly appreciated.

I have the same problem. I bought an 16GB class 10 Kingston SD Card and inserted in my phone . Nothing. THen I disabled Developer options and it appeared. Then I though I will reformat it using directly the phone. Ok. Tried to use it bam "unexpectedly removed " and nothing. Then I tried another SD Card and the same happend first good then removed and so the third one.
Any updates on this thread ? Did you manage to make it work ?

This phone is pissing me off. I am having same problems with stock music player and Goohle Play Music app giving errors on any tracks in my Sandisc 32 gb class 6 micro SD. I have started to wonder if it is related to me using the Samsung Smart dock with a 500 gb external HDD to watch movies on HDTV. It mounts the drive and works great but following day I was try to play music that worked day before and now I get unsupported file type error and other error.
I tried avg to check for a virus(which is unlikely imo) and it shows no virus. I just tried this SD on another android device (Nabi 2 tablet running 4.0.4 and all songs play PERFECT without error. This must be my At&t galaxy S4. Any ideas anyone? I really dont feel like reformatting the sd since it seems to work fine on tablet. Also: I already wiped both music player apps in settings and eventually uninstalled and reinstalled the apps (and another musiv player also) to see if it was cache related. This made no difference.
Edit* oops. After rereading OP... I think I posted this in wrong thread.lol. But my issue with S4 and SD card error with music playback is similar so Ill leave my post unless mod wants to remove it. FYI I fixed my issue(somewhat). Ths SD card is fine as I suspected. The phone has an issue having stock music app, play music and mx player. Either one of the apps was running in background or the system was running sound in background. Hope to not have problem repeat itself. I bet custom rom would fix this if AT&T hadnt locked phone with sneaky update.

You can try flash Rom Cook MH8.
I think your problem will resolve.
Thanks

i think you need to try this.. Get your SD card and try to put in another phone example Blackberry (im not sure if it will work on HTC, alcatel etc. except samsung).
then format using other phone. after formatting ffrom other phone. reinsert the sd card on your samsung unit. then check the storage and try reformatting again using your Samsung.

still nothing
Well. I still do not know how to fix this and I searched and tried almost everything. Only thing that I think might be wrong that somehow the "auto mount SD " does not work.
Because the card is there. The phone cannot see it . Other phones do fine. And in CWM even I can see that there is indeed an SD card but cannot acces the files.
So... I really do not know

i am also having this problem but nothing seems to help have tried alot of thing but yeah :/ sp i have given up on it ! it is a 32 gb sd card loved it.. now i almost got anxiety cus i have so little storage xD hehe well well might buy a new sd soon

My class 4 32gb sdcard too stoped working properly these days.Sometimes it gets unmounted randomly or it doesn't get detected or it shows blank sdcard.I don't know what cause that but the best I could have done is to backup my data and buy a sammy 32gb class10 micro sd.I heard that S4 has problems with sandisk ones.

UPDATE:
My SD Card problems has not been fixed until now!
I just flashed the leaked 4.3 firmware and I tried to insert an SD Card just to try it and BAM! it worked!!! I am now afraid of rooting my phone because maybe the SD Card will not be working again but as long as my SD Card is working I am good!

[Q] MicroSD card problem

Hi guys,
I hope you guys can help me with this issue i'm having as i cant find any answer from searching here nor google.
Basically i bought a Samsung micro SD card that is 64gig (from Dustin.se which is a big company so i'm sure its no fake or anything) and the first thing i did was to format it to exFat using my win8 pc. But no matter what i do the pc see the card as 26gig!!!
I even downloaded a format program from
https://www.sdcard.org/downloads/formatter_4/
Now when i put the card into my S4 it sees it as 26gig which i formated but if i do a re-format it shows as 59gig (or 64gig in reality).
So i know the card is 64Gig but the question is why cant i format it using my pc?
And to make it even more strange when i take the card from my S4 back to my PC it wont recognize it, it wants to format it again. This happens after i format the SD using my S4.
Any idea why?
Basically all i want is to be able to use exFat (for big files) and be able to use the SD card both on phone and PC. Can someone please help me and tell me what i'm doing wrong?

Sounds like a fake or defective card to me. If windows will not see the entire capacity the chip has problems.

I actually got 2 of them and as i said this is the real thing. I reported the first one as bad chip since 2 times i got "corrupted SD" card from my S4.
But now when i test both of them on PC they behave the same. And i actually think the problem with my first SD is the phone that corrupt some files (just a feeling) since it works fine when i restart the phone.
Any other ideas? (i tested on my Macbook and another PC win7 with same result )
Do you have an 64gig card? if so did you format it using pc? and have your tried to format using S4 and put the SD into PC? did it work reading from it? What was the format S4 formated (Fat32 or exfat)?
ps. i run stock ROM so no root or anything.

When you have the chip in the PC right click My Computer/Manage/Storage/Disk Management then find your chip on the bottom, right click on it, then delete the partition, form a new one then format. Check and see if the proper storage amount is there after. I cant see the phone damaging the chip but who knows anything can happen.

Are you running xp? (Edit Sorry now I see you aren' t. Card reader? ) Older versions of Windows only have ability to read sdhc as opposed to sdxc so have problems with cards over 32gb (max for sdhc standard)
If so borrow a newer pc. The card probably was exfat from factory though. I've a 64gb card from Samsung as well (fat32) and had the corrupt message a couple of times. Fixed with remount.

Samsung 64gb user here. No probs at all. Formatted it once on my phone when i got it.

As you saw i tested on windows 8 and 7 so dont understand why it dont work
And as you say a remount fixes the corrupt problem so i dont think both my cards are fine but cant understand why i cant format them on my pc....
I want to be able to pop it out from the phone and copy/paste but as it is now when i format it on phone it gets unreadable on the pc which is also really strange. .

Ok i figure it out, i was to tired to think last night
The conclusion is that my microSD converter was obviously not compatible with the SDXC i assume, i had 2 usb stick that take the micro SD but when using these on my windows8 they were both detecting wrong. I had also a coverter that is in the form on regular SD card so when i use this one and put the micro SD in my laptop with buildin SD reader i see the 64gig right away and can also read the memory when i take it from the phone. So all works now.
I need to find a USB stick converter to be able to use it on my big PC
Thanks for the help guys.

[Q] Note 3 camera unable to save on external sd card

Hi All,
I have a stock non rooted Note 3... Recently bought a 32GB class 10 micro sd for it... Whenever I change the storage for camera to sd card it clicks a picture with an error of unable to save to sd card switching back to device storage....
1) Why isnt it able to use the sd card for storage
2) I have formatted the card multiple time both via pc n phone
3) read abt read-permissions but didnt find much applicable info
What can i do about it as I can copy paste file via pc to micro sd successfully and the files reflect properly in the phone...

I have conducted these tests:
1) Used my 32 gb card on my old note 2 and camera is able to save pictures directly on it
2) Used my old 16 gb card on my new note 3 and camera is able to save pictures directly on it
Conclusion:
1) Note 3 is functioning properly with 16gb card but not the 32gb card
2) My 32gb card is fine as note 2 is able to write on it with no issues
There is a problem with Note 3 unable to write on a working 32 gb samsung class 10 micro sd...
Awaiting a solution..

Is your card anyway protected or something? I got 32gb class 10 card from Samsung and and it's working fine (If I remember right the card was some red/grey colour, bought it couple months ago and it worked as well in my old S2)

I have finally tried additional steps with no success:
1) bought a new samsung class 10 micro sd card --- not working in my phone
2) formatted the new card --- no change
3) used it in my friends note 3 and it worked fine
4) did a factory reset on my phone --- it worked for 2 mins and again started giving the error
what is the issue here???????

For what it's worth... Although I have a Note 2, after updating stock Android from 4.1.2 to 4.3, I recieved the same errror. You might also have 4.3, since 4.1.2 has not been delivered on the Note 3. Maybe an Android 4.3 issue, instead of a Note issue?

Solved. I checked my SD card: 2 corrupt files. After making a backup of the SD card, I performed a full format and placed all files back on the SD card. Camera now stores pics on SD card. Card clearly had an issue. Whether this has to do with android 4.3 or not, I don't know.

I just talked with Samsung support after a 64gb class 10 failed and a 32gb class 10....They told me that their phones dont support class 10 cards officially and that they are known to fail. They suggested that I ask the card manufacturer to replace the card with a lower class.....something about the way files get written...basically they know its an issue but dont have a time table for it to be resolved if it will be at all.

Can't write to Note 3 SD card
I have the same problem, I can only write to the SD card if I take it out of the phone and do it with my computer.
I purchased a Transcend 64GB card with the phone. The dealer exchanged the card after he satisified himself there was a problem.
I still have the same problem.
Can't write to the card, via any of the following (or get a partial write and failure with a corrupt file) USB, Kies, Airdroid, or file copy from internal to external card.
I have to take the card out of the phone and write to it with a PC, then I can read the files.
I'm beginning to think this is a manufacturers defect in the phone, I've seen a couple of other posts on this same subject. One was on the Sammy site.
I would like to solve this issue without having to submit my phone to Sammy under warranty and be without a phone for however long.

2) formatted the new card --- no change
3) used it in my friends note 3 and it worked fine
4) did a factory reset on my phone --- it worked for 2 mins and again started giving the error
what is the issue here???????

The only way i could fix it was to use a Samsung 64 GB Class 10 card... but that card as well is a little dicey to use as once my battery went low and the phone got switched off and corrupted the memory card... so i just use it for movie storage, no camera pics...

I have the same problem, I can only write to the SD card if I take it out of the phone and do it with my computer.
I purchased a Transcend 64GB card with the phone. The dealer exchanged the card after he satisified himself there was a problem.
I still have the same problem.
Can't write to the card, via any of the following (or get a partial write and failure with a corrupt file) USB, Kies, Airdroid, or file copy from internal to external card.
I have to take the card out of the phone and write to it with a PC, then I can read the files.
I'm beginning to think this is a manufacturers defect in the phone, I've seen a couple of other posts on this same subject. One was on the Sammy site.
I would like to solve this issue without having to submit my phone to Sammy under warranty and be without a phone for however long.

New Card only works a short while.... Then
When I had my Transcend 64GB card replaced, it was ok for a short time then it went back to the old problems. I can't write data to the card while it's in the phone only when written from a PC. If I save a file somehow from the phone (which usually fails) the file will be corrupted, such as a song or movie it will not play smoothly, or perhaps at all. Save it from the PC and it's ok.

Actually android 4.4.2 kitkat can't save anything to sdcard...except samsung's app, because i had this issue too

Can't write to SD Card on Note 3
I was having problems on JellyBean 4.3 with writing to SD card, got a new card and everything seemed ok for a little bit. Then issue returned. Upgraded to KitKat 4.4.2 and problem is worse if anything.
I have seen fixes for this issue if you are willing to root the phone and void warranty to fix it. I have 3 other rooted devices, I could root the Note 3 but it's brand new, I don't want to blow the warranty away.

The only solution is just wait for another samsung software update
