[Q] best way to change your SD card ?

Hi guys,
I have a 32g class 10 sd card I bought to use instead of my 16gb class 2 but I have been facing quite some issues in the last couple of weeks
I took the 32g, put it in my win7 PC, formatted it to FAT32, safely removed it and now the arc doesnt recognize it... I just wanted to format it via the settings-> storage -> erase card in order to make sure everything is all peaches and cream before loading 20+gig of music in it.
...
All I want to do is finally transfer all my music (24ish gig) to the new 32g , and back up all my apps and stuff via Titanium Back Up pro.
Simply said, I want to have my 16g card data in my 32g one , with all my beat
Please could someone share some tips or links, I'll do homeworks and have been, but I have been facing so many complications since the last few weeks
Thanks in advance

Does your phone recognize another card properly?
Did you apply a volume name when formatting the 32GB card?
Did you try the 32GB card in the phone before formatting it?
I've done pretty much the same as you with a 32GB card (Kingston Class 4) and had no problem.
Are you sure the 32GB card is good and not a counterfeit?
Try formatting it again to with FAT32, default parameters, short or no volume name. Try copying your files to the card on the PC to see if it actual works.

Thanks I did put a volume name. That might explain it.
Yes the card already worked ( plenty of times ). I have been trying numerous time to transfert the music ( takes forever to transfer 20gig to an SD card , even class 10... ), and had mixed results that always ended up failing ( most of the times because of me... like forgeting to safely remove the sd card from my laptop made the card unrecognizable by the phone afterward...of course I just finished to tranfers the 20gig and was too happy to safely remove it... )
I will try that right now. thanks again
*EDIT*
Bah still same problem I must be doing stupid... SD card is not recognized by the phone. In the settings menu ( storage ) I cannot mount or unmount it and thus format it via the phone itself
That even after reformating it to default FAT32 partition with no volume name using MiniTool Partition Wizard Home
So number 1 priority is getting the SD card to be recognized again by the phone
**EDIT2**
When browsing the card with astro it says problem creating external cache , with root explorer it only says directory is empty. Still can't do anything in the settings menu

Obvious statement, but did you set it to primary?

It's a memorette class 10 :S

Or format it wrong, Arc will say it's damaged and say that it has to format it to detect it.
Should fix it, too.

Ya I'd love to get to this point ( which I got in the past hehe ) but at the moment it's still not even recognizing the sd card anymore
still formating btw....

How did you recover your issue?
I think I have a similar SD card problem. But, I encountered it after I did factory reset with SD card erase option selected. I didn't do anything after all. When I connect to PC, on the phone upper bar, there is no notification regarding USB. The middle button seems not working either.

Try formatting the card with this Panasonic SD/SDHC/SDXC Memory Card formatter.

That's strange why not just do a quick format in Win7 or WinXP, to FAT32? I use a 32GB as well and Arc has no issue with it. Coming from the 8GB, here's what I did.
1. Take off the 8GB from the Arc and placed in a USB reader.
2. Copy off all the files to your PC. I used WinRAR to accomplish this, just archive everything and STORE it (no need to compress so operation is faster). Or you can just use drag and drop plain copying its all the same.
3. Analyze the copied files and remove all unneeded bloats (ie. old movies u don't intend to watch anymore, clear out useless temp files, etc)
4. Copy back the files on your new FAT32 formatted card using the USB reader, then put in your Arc.
If you notice, the entire data migration is done via card reader/USB. Using the Arc as such will slowdown your progress and introduces unnecessary delays.

You can also use usb tool, it basicaly creates a back up image and can be restored to the new sd

[Q] SD card not letting me add or delete files

I've been spending waaay to much time trying to get this phone to work as I had expected with previous phones (even my LG G2x) giving me less problems. I recently bought a Sandisk 32gb, class 10 micro sd card and after transferring old music, pictures and videos from my old LG G2x with a 16gb card, placing files from my computer back onto my S4 with the 32gb card is a nightmare! Photos are transferred but too out of order to try and deal with although it's more the music problem that has me bugging. I have some success after putting about 3gb or so onto the new*32gb sd card but after that, the sd card flips out and starts using special characters for file names. Below I attached a screenshot of what I'm going through with another app called V1 Golf for Android. I'm stuck and any help is much appreciated. I can't delete anything on my sd card nor can I add. I've reformatted this card about 4 times now without success. Some say that a Sandisk have been nothing but problems for them, you think a Samsung card could be the fix?
I'm also running windows 7 on my computer as some people have said that could interfere with the transfer but it seems like that's not the problem being that downloading apps from google play shows corrupted files depicted below.

First, did you format this 32gb sdcard using fat32, exFAT or NTFS or ?
If you did not format it with fat32 then that could have caused the problem.
First you need to remove the card from the phone and plug it into your
computer using the adaptor which came with the microsd card so it can be
tested and repaired in windows.
Once the card is plugged into the computer and it's recognized by windows make note of the drive letter.
Then open a cmd prompt in windows by going to the start menu clicking on RUN then type "CMD" and click OK to open the DOS prompt.
Then in the black DOS window type: chkdsk E: /F then press "enter" to scan and fix errors on your microsd card.
NOTE: The E: is just an example, check the actual drive letter of the sdcard which is plugged into the computer.
Please note, doing the above will not delete any files or folders unless they are deemed unusable and cannot be fixed.
The chkdsk will NOT not format your microsd card.
Good luck!

Unfortunately I ran into a very similar situation with a 64gb SanDisk card. After several months of using it successfully without issue, out of nowhere some 20 gigs of data were stuck. It seems that 1 file in a nandroid was corrupt. After formatting, re-partitioning, deleting etc, etc. with Windows 7 as well as MiniTool Partition Wizard I was unable to ever get the corrupt file to delete. Thus leaving the $60+ card useless and a prime candidate for the trash. I chalked it up too a "bizarre" instance. I have since purchased 2 64gb cards, one to replace and one for my new S4. Haven't had the issue since (knock on wood). Not sure what the exact culprit was, the recovery? (TWRP), a freak occurrance? or Just a defective card? If you have any luck saving your card please post how you did. Although I realize this probably isn't helpful except to know your not the only one.

My sd card seems to be stuck.
About 20 of 64 gb being used.
Now I can't delete anything. Or add anything.
It appears to delete and then it just comes back.
Does that mean my sd card is dead.

scandisk 64gb
Had the same thing just happen to me. Transferred a few kernel files yesterday and today couldn't delete, add or format anything. I was able to copy all files to computer but that's it.

same thing happen to my sandisk 64gb class 10 microsdcard as well
is it a virus?

I had the exact same issue with a San-disk 64gb micro sdcard, I contacted San-disk, they offered me a replacement card.I suggest you do the same, hopefully they will exchange it for you.

You can use another SD card to try whether this sd card is dead.
If anothe SD card can delete files, it proves that this sd card is dead, vice versa.

Did your problem solve? I'm experiencing now like with your problem. And I'm looking for an answer.

[Q] SD Card copy freeze

Hi!
I just installed the UK Jelly Bean ROM on my Galaxy Ace 2 and i haven't noticed any issues while using the phone. However, when I try to copy a big file to my sd card connecting the phone to the computer (using mass storage mode), the copy process just freezes. Connecting the SD Card to a normal SD adapter works, there are not any issues copying files that way, but it's imposible to copy files using the phone. Any way to fix this?
Thanks!

there's no problem in it...if you have done partitioning then you may have the problem.Try rebooting the phone

I thought I was the only one! I don't think there's a fix for it, not as if Samsung care. Be careful, because of how many times I've had to re-copy files and the constant freezing my SD card was destroyed!

Yeah, that is really annoying, you are not the only one. I've noticed that on MB2 as well, I thought it was a problem in the leak version but it seems they did not bother fixing it. I don't think there is a fix apart from using MTP rather than mass storage for now. Or use apps like AirDroid (or similar) to copy files via WiFi/Data.

It may not be completely destroyed - have you tried running chkdsk /f (or fsck on linux) on your SD card? That saved my card anyway

I usually just take the SD out now and put it into a card reader, I don't like MTP or the hassle of other apps. Besides, I never use the internal SD anyway.
It's definitely dead, I've tried everything from low level formats to what you mentioned. Completely dead, like the one I had before it.. My last phone and the Ace have went through a 32gb SanDisk, 16gb SanDisk and a temporary 4gb no name card in the space of just over a year.
I've had a SanDisk Mobile Ultra 8gb in for a while now and it appears to be working fine so I'm quite happy atm

Problem with 64GB Micro SD and Note 2

I'm using a 64GB Sandisk micro sd card. Running wanamlite v4.0.
I can't seem to delete or add files to my memory card. Every time I delete or add a file and restart my phone, either the added file is gone or the deleted files are back. Tried formatting multiple times with different softwares. Files all still return back. I also ran some diagnostic tests and they all came back error free.

I have also 64 gb micro sdxc sandisk card. But no problem with that. I have kept extFAT partition.
Try on different phone and check for same problem.

I also have the same problem, stuck it in my brothers galaxy s3, did reformat, but it stays the same, same files are still on it. can't delete or add any new files to the card. it seems stuck or something. i did use twrp to wipe it as well but says succesfull upon reboot still the same.
(partial change) i actually can add files to it sometimes, even through my computer, but after a while which is random it seems or a reboot the files are gone.

[Q] Micro SD card works on PC but not on S4

Hi,
I have just purchased 64 GB Class 10 Samsung micro SD card with a SD adapter and USB adapter.
I plugged it in to my S4 and everything seemed OK. Copied all of the contents from my old SD. Everything was working fine until I restarted my phone. After restart all of the files were present by could not access them. Some of the files and folders had ~ as prefix. Plugged the card in my PC and the files were corrupted. Recopied everything and tried several times again. The same outcome. Reformatted the card to exFAT and to FAT32 both from my phone or my PC using several available programs. No success. Whenever I unmount the SD card or restart the phone the files get corrupted. So I figured the card is broken. So I decided to test it only on my PC. Copied lots of stuff to it (music, movies etc.) and started using it on my PC. I have mounted/unmounted it on my PC probably 100 times and it works just fine. So that means that the card is fine (or am I wrong???). Also tried it to plug it with the usb adapter into my TV. It says that usb disk is empty.
The files only seem to get corrupted when I place the card in my S4 and unmount it/restart the phone. The card works just fine on my PC.
Does anyone else have this issue?
I am running a rooted 4.3 Android OS.
Thank you!

You have to partition the card into 32GiB chunks. So make two, 32GiB partitions and it will work fine in your S4, except it will show you have two external sd cards.

If you don't want to make two seperate partitions on your external microSD card then do the
following:
Remove your external microSD and plug it into a card reader and or the adapter which came
with the card then plug it into your computer.
Make an empty folder on desktop of computer and copy all files and folders from the microsd
card into the empty folder.
Format your external microsd using this windows utility and copy all the files/folders back onto
the card from your computer and replace it into your phone.
Here is the direct download link for this fat32 formatter which is a windows utility:
http://download.cnet.com/MiniAide-Fa...74ffba47b88ad1
By doing the above your external microSD card should work fine in your phone.
Good luck!

Thank you for your reply. I did as you suggested and it worked for some time. I mounted/unmounted several times and it seemed fine. Then did a restart and the files were corrupted again.
Why does the card need to be divided in 2*32GB in the first place? Isn't the S4 suppose to support 64 GB cards?
Your suggestion seemed to isolate only part of the problem. It remains only the restart. What can be associated with corrupting data on sd card and android restart?

No, it depends on your kernel if it supports a certain FS. I am not sure why your files are being corrupted other than one, your ROM isn't unmounting your card properly on restart or two, your card has issues. Again, I am not sure.

In that case do you suggest I try changing kernel? Do you think that might help? My kernel version is 3.4.0-2082040 if that means something. Do all S4s come with the same or different kernel? Will it help If I unroot or maybe install other ROM for different country or different operator?

All the stock S4's come with the same kernel, so if your S4 is stock then it's not a kernel issue.
Have you tried any other external microsd cards, if not that's what I would do next.
Most of the better microsd cards have either a 2-3 year or a lifetime warranty.
Good luck!

I currently use my old 8GB sd card with no problems whatsoever. My S4 is rooted. Does that change the kernel? Should I unroot?
