[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

HTC One V ~ SDcard unaccessable??

Recently got my phone which runs through Kodoos and cant seem to find an answer online via HTC manual?
ive browsed several SDcard threads here on the forums and none seem to be covering my problem?

[Q]: Is there a way to format this SDcard?
[Q]: is there a way to change the setttings whereas pics, music ,etc, can be directly sent to the SDcard?
[Q]: how do i access the SDcard when it wont let me into the card or it shows it is unavailable?

Try to format the card in pc using an incompatible format like ntfs and then put it in the phone and then the phone should ask you if you want to format the card. If not try to go to settings and format manually.

dude. just format the sdcard using your pc in FAT16 format. you can also try fat32 but I don't know how it plays with android.
cheers!
PS: after you format it using the above method, it's good to take the sdcard out from your phone and then put it back. just to be on the safe side

well...tried FAT16 and no luck?
im getting very frustrated at the thought of a phone that doesnt even see a simple SDcard when my PC does?

Well it might be some hardware issue. The phone does not recognize that sd card is in right? Does the phone show something when you plug in the card while the phone is on?
Did you try to put in other card?

nothing shows up when putting the card into the phone while it is on, but it does state SDCARD REMOVED when pulling it out from the phone

May be the SD card have some defect. Insert some other SD card and see if the phone nose it out.

ill probably end up doing that and just buy a new sdcard but i have a feeling itll do he same thing seeing as my PC sees it just fine and my last phone used it without a glitch. Now formatting this card for this phone, ive lost 1gb of photos!

Well I just did a small test. I have formatted a spare SD card with NTFS(I used MiniTool Partition Wizard for that) and put it in the phone. It told me that the SD card is blank and not properly formatted and asked if I want to format the card.
So this is something that your phone should do too. So my conclusion is that there must be either something wrong with the card or with the phone. So hurry to try a different SD card and if it doesn't work you should ask for replacement device.

thanks everyone so very much for all your help!!!
i called Future Shop (where i purchased my device) and explained everything including your guys help to them, and they said it sounds like the devices card reader is defective. So...seeing as i just got this on Friday last week, i can exchange it for a new device at no cost.
:good:

just got back in from future shop....
seems it was the sdcard that was defective but...
after coming home, i reformatted the old sdcard back to ntfs and dropped a pic on it from my PC and it still works?? lol
for some odd reason the device just didnt see the card? maybe cuz it was generic? maybe cuz it was only 1gb? i dunno??
however...got me a new 8gb sdcard for 14.00, thatll do me just fine!!
again, thanks for all the help

Q. SdCard

So lately my sd card keeos getting removed unexpectedly?... its not getting removed or anything. Will wiping it aka formatting it make it okay again?

I suggest you read this thread. A lot of members have had sdcard issues. Good luck!
http://forum.xda-developers.com/showthread.php?t=2031009
Btw, I have been using a 64GB SanDisk Ultra Class 10 for over 6 months with no issues. All my music, videos, ROMs backups etc are stored on the card. It gets heavy usage.. the biggest common denominator of the thread appears too be that the size of the card is the main issue and not the brand. 32GB cards are having the most problems.

Hard to say when you didn’t tell us what kind of SD card it is, what size, and how long you have had it. You need to give more information.
If it is a 64 GB card, it is because android natively does not support exFAT file systems for storage. Your issue is that the format is not compatible. In this case, flash perseus kernel found in the original android development section. Problem solved.
If it is an SD card of 32 GB or less, the issue is likely that you need to just format it. In this case just find an adapter to plug it into your PC, when the little window pops up asking you what you want to do “open folder to view files etc etc” all that… just close that window. Open some other folder (doesn’t matter which one) and on the left side you will see the drive shown. It will probably show up as F: or something… maybe G: … maybe Z:… who knows… but it will NOT be C:… C is your computer drive, don’t touch that.
Find the storage device on the left side, RIGHT click on it, and select “format”….
UNCHECK the “quick format option”…
For the file system select “FAT32” and for the cluster size select 32kb… (default is 16, but 32 is better and will provide better performance.)
Start the formatting. It will take a while… so go grab some lunch. If that doesn’t solve the issue then I don’t know what to tell you without more information but my guess after that would be that you have had the card for a while and it simply needs to be replaced.
What size card is it, what class, and who makes it?

That's weird my 64GB SanDisk Class10 card, that I have been using for months on my Note 2, is exfat and I haven't had a single issue with it.
My card was exfat right out of the box and that is how I used it. Right out of the box. I have NEVER formatted it.
Edit.
I'm on Tweaked now. Before that Stock Android.

What is wrong with my Note 2?! PLEASE HELP

Hi I recently purchased a Note 2 from a guy on craigslist. I checked out the phone at purchase and everything proved to be correct. I didn't expect however that he had the phone rooted. I'm a big fan of rooting phones that don't have a good operating systems already or didn't have Android JB but phones like the galaxy phones I believe don't necessarily need to be rooted. I was pissed because I wanted it with stock rom but I just decided to accept it and unroot it myself. So after a long process I got it unrooted and running the latest stock rom and everything seemed to work except for one thing. When I transfered all of the Music files from my previous phones microSD(16gb) to my new one(64gb) none of the music files worked. All of them wouldn't play and the phone would say it can't open the file or something like that. So I tried formating the microSD and trying to put the files on the microSD again and still the files wouldn't play. I had to format the card through the phone itself and transfer the files through Samsung Kies just for 3/4 of the music to work. I can deal with 3/4 but now when I transfer a video file weather through Kies or straight to the folder none of the files play. When trying to play them nothing shows or sounds it's just black screen, you can fast foward or skip but nothing shows. I never thought I would have this much trouble with this phone but it appears as though there's a virus on the phone or card or something that is preventing video and music files to play. Even when trying to play files from the phone on Windows Media Player or any other music/video player the files don't play. I have also found that whenever I connect the phone to my PC let's say a day after I last connected it, I have to run USB connections on Kies and it has to reinstall the drivers for the phone just to actually see the files on the phone. Please help me I have no idea what to do. Thanks in advance.

You need to flashed a kernel that support exFAT format for 64gb or you can format your 64gb to FAT32 format, but for me i prefer to Saber Kernel and i don't need to format my micro sd card, you could try there are other kernels available for stock rom you can find them here...http://forum.xda-developers.com/showthread.php?t=1987541

So you're saying it's the microSD's format? It has nothing to do with the fact that the phone was rooted and that it might have a bug? Would kind of make sense because when I put the 16gb sd card in the phone all of the music files work. So it's the format, but I need a kernel? I have also found that whenever I connect the phone to my PC let's say a day after I last connected it, I have to run USB connections on Kies and it has to reinstall the drivers for the phone just to actually see the files on the phone. It'll show the phone but it wont show anything inside it just shows blank. Excuse me if I'm coming off idiotic, I have no experience with this phone or 64gb microSD cards lol

Since you're unrooted, you can't flash a new kernel so you may want to dismiss that last thing.
Have you tried only one 64gb microSD? It seems that your card may be bad or it's not formatted correctly for the stock firmware... I would test out another 64gb card and see if that works since the 16 works just fine.
Edit: Sorry... a little vague... the card needs to be formatted as Exfat if you can do that through Windows, that should work in case the card is actually in good condition.

I don't have any other 64gb microSD cards, the one I have came with the phone. The logo and everything on the card have faded out so I don't know what brand but I think it's sandisk. I don't know at this point I'm thinking it has to be the card because I've tried nearly everything and it's still not working the way I want it to. I formatted it using Windows UGI to FAT32 since thats what you said and that was the same format as the 16gb and sure enough most of the music works with some not working. So I tried putting movies on the card and once I didn't see a preview on the bottom left I knew it wasn't going to work. Seems like the card is bipolar I have a 32gb micro I'll try that, it's brand new still haven't used it, should I just put it in and see if it works or should I format it to FAT32? By the way Thanks again really appreciate your help!

I think he mention phone is rooted sorry if misread that part thats the reason i recommend to flashed kernel that support exFAT, actually as far as i know 64gb microsd card default format is already exFAT and 32 or 16gb is FAT32 and some are in exFAT. If doesnt want to flashed kernel then i recommend format sdcard from computer just plug in from card then right mouse that drive then format and select FAT32 format. If some instance your computer can't read your microsd card and cant format there is chance thar your microsd card maybe bad.

If you can see the files in the player, and you can see the sd card directory using a file explorer, its not the card. I had to add two lines to my system settings file. I'm sorry I don't remember the file name or the content of the two lines. Maybe my comment will jog someone's memory.

I've formatted it to exFat a million times. That what I originally was formatting it to because windows quick format doesn't have a FAT32 option only exFat which was default and NTFS. exFat is not the problem.

It's looking more and more like SD damage...
Considering the fact that other cards work fine...
Copy your media to PC from the SD...and get a new card ?
I know it sucks...
And once the new card is installed...be "very" careful moving those files back as they may be messed up...
I'd pull a few songs from the PC after you copy them over and test them on another card to be sure before loading it to a new and expensive SD...
It sounds like the phone is fine...g

Try to format to NTFS first then format to FAT32 if doesn't work then maybe a bad microsd card

I'm not being a scumbag. The card works it's just has some problems but it works. I mean I don't know how the card would react on another phone or maybe someone would use it as their card for their camera I don't know. You're acting like it doesn't work at all and I'm going to try to screw somebody into buying a defective card.

Suddenly Getting SD Card Unexpectedly Removed Error

Been working fine for over a month now all of a sudden the SD card appears to be randomly mounting/unmounting itself and has become unreadable on my phone.
I've put the SD card in my PC and it works fine so I suspect my phone has developed a fault. I hope I don't have to get an exchange as it's otherwise faultless and I'm dreading getting a unit that can't be S-Off'd
I haven't modified or installed anything prior to the fault developing,
Any tips would be most welcome.
PS It's a genuine Transcend Premium 300x 64GB bought from MyMemory.

I've put the SD card in my PC and it works fine so I suspect my phone has developed a fault. I hope I don't have to get an exchange as it's otherwise faultless and I'm dreading getting a unit that can't be S-Off'd
I haven't modified or installed anything prior to the fault developing,
Any tips would be most welcome.
PS It's a genuine Transcend Premium 300x 64GB bought from MyMemory.

Copy everything off sd card. Convert to fat 32. Copy everything back.

Stock but rooted and S-Off'd
I've not tried a reset yet but it's been as good as gold until about an hour ago when it suddenly started flashing between "preparing SD card" & "SD card unexpectedly removed"

I'll give that a go but why has it been working fine for over a month whilst exFAT if that is now the cause?

well, a simple solution is to enter recovery and see if the sdcard works there if this way it works, change the rom/perform factory reset, if this doesn't, well, you might try to flash everything again, but i's possible that the sd slot is broken...
i wish you all the luck, let me know

I would copy EVERYTHING off the card to a PC and do a format and try a different file system. I would has perform the format on the phone, to make sure its gets formatted to the correct file systems.
Long story short, It sounds like you memory card is starting to get Corrupted. I have to SanDisk cards that started doing that in the biginning and ended up not being read at all on PC nor the Phone.
Also while its doing that, youll also notice the battery start to drain more, at leasst thats what happended on my Note 3 when I had the san disk cards going corrupt.
Ended up buying new Card and now everything is fine.
I doubt is the card reader built in phone, more then likely its your memory card going corrupt.

I agree most likely the card. I'd download an sd card format tool and do a full format, don't use Windows format then do full check for bad sectors. I had a similar problem and it was the card at fault, but strangely worked ok on the pc.

I have been through many a Samsung phones and always had corrupt sd cards in exfat. One day I saw a thread that said convert to fat32 and have never had a problem since.

Thanks for all the advice.
I could read the card in recovery but it failed to format there.
I tried to format in windows but my only options were NTFS or exFAT, no FAT32. But this failed anyway also.
Downloaded a SD format application but this said the card was write protected and to move the lock switch, obviously MicroSD has no switch like standard SD.
So next I deleted all the files on the card and ran h2testw test. This failed and reported card is probably faulty.
Then I checked the contents of the card again and all the original files were back again, so it's definitely 'Donald Ducked'. I was able to get all my files backed up and fortunately I had my photos already thanks to Dropbox & G+.
So I will now look at getting MyMemory to replace it but my fear is they will want me to return the faulty card but it has sensitive information on it that I can't delete. Any ideas on how I can wipe it?

How did you attach the card to the pc? Try a usb card reader and then try again. If still problems download mini partition tool (Google) and delete the partition. You can then wipe it properly.

I reformatted the SD card from the settings within the phone and since then it been working fine :\
make sure you're using 2.0USB also..

when i connect my phone to charger
Its been few days i am noticing when i conmect my phone to charger it says 'sd card removed unexpectedly or either it suddenly stops showing content from my phone, then i have to go to settings unmount/mount the sd card frkm storage option and then it shows the content even when charging, or sometjmes it doesn'fshow option for that so on that case i have to restart my phone. What could be the possible reason and solution to that. It was fine on 4.4.4 now i am on 5.0.2 all stock htc one m8 h/k edition with sim unlock and s-off via sunshine.
