SD Card help

(if this is in the wrong section I apologise)
This isn't a problem for myself, I'm trying to help my brother's girl
Basically, when her phone has the SD card inserted, it says its unmounted yet it won't mount. So, tried plugging it into a PC with an SD adaptor and it doesn't even show up...
Is there a way to fix this or is this SD card busted?
Thanks in advance

The fact that you cant even get the card to show up as mounted in Windows is not a good sign.
Was there important stuff on there? If so, you could try one of the SD Card recovery programs. I've used them in the past, but if you cant even get it to mount in the PC, they are probably not going to work.
But, to me, it sounds like the card is busted. Do you have another one you could test the phone and adapter with? If not, try and exchange it if it isnt too old.

Tried putting it into another phone and its still showing up as Unmounted with no option to remount it.
All that was on was a few music files and other assorted useless junk

What's her SD?
Some fast and high capacity micro SDHC are damaged I don't know why. I tried once a Patriot 32gb class 10 and it got broken in about 1 month of usage. The same occurred with a Sandisk 16gb class 10. Don't know if it's an app that is causing it. Now I'm using a Samsung 16gb class 2 normally. The broken SD were recognized in Windows as RAW partition.
I tried some Fixers without success. You may try them.

Just a note: Most android devices only allow FAT(32) partitions. NTFS shouldn't work.

Micro SD Card Issue

im having an issue all of a sudden where the external sd card wont delete anything i tell it too. i mount it to the computer and delete things that way and copy things on but when i disconnect everything is like it was nothing happened.
also formatting it in setting via storage did nothing all the files are left in perfect order
Ive even mounted to the computer, formatted in MY COMPUTER and it says its completely empty. Then i unmount it and guess what nothing was touched. can someone please help
I take that back even deleting within my files does nothing.
I just stuck in my sandisk 16gb class 4 and it isnt having any issues so it must be the 32 gb sandisk class 4 is the card messed up?
I'm using it with a skyrocket and im on skyics with the latest base. I'm posting here because this card has been in many other phones and never had an issue till now

pwnerman-
Reading your description of the issue .. have you tried physically removing it from the phone and inserting (either by adapter or multimedia slot as most computers have now-a-days) directly to your computer ?
Meaning .. have you tried doing this without it being in the phone ?
Yes .. I snapped at you in the thread and I apologize .. with all the BS going on in there, more and more people are getting on edge.
My answer in the thread also stands in regards to how the card is formatted. I honestly do not know your experience with computers .. thats why I threw it in there.
I have a Sandisk 64GB card in my Skyrocket running Seans latest ROM .. only way I could format my card FAT32 was actually using a single command line program called "fat32format.exe" .. and with ALL of Seans ROM's, I have never had any issues with SDCards at all.
Here is my original thread about the Sandisk 64GB http://forum.xda-developers.com/showthread.php?t=1586295

I've done everything but attaching it directly to the computer because I have no adapter to do so. I bought one of the cheap dollar ones on Amazon a few hours ago. I've used that card in like 10 phones on triple as many roms and never had a issue till now. I do think it could be a Rom issue because the other Guy was having issues and this was the first time I did anything on the card since switching to the 4.0 skyics Rom.
I even put it in my captivate and it wouldn't even format in recovery mode. So I honestly don't know considering it wont work in the captivate either

[Q] 64GB SDcard format question

I ordered a new Sandisk 64GB SDcard but after reading many threads on the topic here, I have a question about the format. From what I've read, in order to have the card recognized by CWM and other custom recoveries, it needs to be in Fat32 format rather than exFAT. Many people have suggested that you can use a Windows based 3rd party software to properly format the card, but I don't have a SDcard reader on my PC so I'm not sure what my options are at this point. I tried searching the forums about posts from people in a similar situation (i.e no card reader on PC) but was unable to find anything. Any suggestions or ideas on what I can do to retain the full 64gb capacity and still be compatible with CWM without having access to a SDcard reader? Thanks very much.

Will need to find a PC to format it. It comes ExFat and not only recoveries won't see it but roms/kernels may not see it either. The program is guiformat. Can Google and find it easily. The site is little confusing. Click on the picture of the app and it will give you the download.

Thanks very much for the response. I was afraid that would be the case. I honestly don't know anyone who has access to a SDcard reader, so I might have to just end up returning it to Newegg for a 32gb version instead. Thanks again, I sincerely appreciate the info.

I thought these issues were exclusive to just the 64gb variants.
I actually dug around in my basement and found my old PC tower that has a built in 8 in 1 card reader that supports SDcards. If I can find a way to extract it from the old tower and hook it up to my new one, I may yet find a way. Thanks again for the continued help.

Yea. Only difference between 32 and 64 is don't need a special program for 32. Windows can do it natively. Good luck.

I realize this question may sound ridiculous, but I figured there was no harm in asking.
Is there any chance I could stick the 64gb card in my old Droid X, connect it to my PC, and then use the program you suggested to format it to FAT32? I guess I was hoping the phone could act like a SDcard reader of sorts for my PC. Thanks again.

I had a droid x but I'm not sure if it handled a 64gb but if it does you should be able to format it the way you want.I bought a $4 usb micro sd card reader for my SanDisk 64gb card and I hooked it up to my pc usb slot and used a partition program and was able to successfully format it to fat32.Have not had one problem with it being recognized by any Rom or kernel, think it gave me 59gb total after it formatted.

Thanks. I had no idea they were that cheap. If the DX idea doesn't work, I'll just stop by my local Microcenter or Best Buy and pick one up. Thanks again.
Edit: Am I correct in assuming the product linked below would do the job? If so, it's only $1.99 so I think i could manage to afford one.

Won't work from phone but go to radio shack and get cheapest one of these you can find. May be able to get with 1GB card. Take pic and show them what you want. Sorry I been busy and didn't think about it. Good call Droid. $12 max.

So I purchased a SDcard reader, hooked it up to my PC, and formatted it with the guiformat program that was recommended earlier in the thread. I set the allocation size to 65536 and left the Quick Format option checked. However, after it finished, both Windows and the S3 only show it as a 32gb card (approximately 27 GB total storage space). Is there another formatting program for Windows or any other ideas you could recommend so I can get the correct storage size (64gb)? Thanks again.

I tried using a few different programs to format the card to FAT32 but every time it still showed up as a 32gb card. I ordered it directly from Newegg so I don't think the authenticity is an issue, but I have no idea what could've caused this to happen. Regardless, I sincerely appreciate the help I got from the folks in this thread and via PM. Thanks again for your time and effort.

There's another thread detailing all the issues with exfat 64gb cards here:
http://forum.xda-developers.com/showthread.php?t=1698672
I encountered the same "hiccup" as you pertaining to the 32 gb issue.
I ended up using a program called EaseUS Partition Master to finally get all back to normal. I wiped my sdxc partition, it did come back with some message that something didn't complete ???, but then I formatted as fat 32, primary partition, and got the entire 64gb back and so far... ( fingers crossed ),.. all seems to be working well.
With the card formatted as exfat, as soon as I got around 8 gb of music, photos, etc.. the card simply would loose its' file structure and just start acting weird. All files would still show up if I pulled the card and put in an sdxc reader on the PC... but my Galaxy S3 never would recover them properly.
This has got to be some kind of "bug" in the phone as you'll see in the other thread this problem is quite common.
For what it's worth.. I seemed to have much better luck transferring large chunks of data with the card in the reader opposed to hooked up while in the phone. ( speeds kept dropping via the phone cable )
Good luck!

Thanks for the info. I actually tried the EaseUS Partition program you referred to, but it still remained at 32gb. I ended up returning the card to Newegg and will just get a 32gb to replace it as I'd rather not have to repeat this process. Thanks again for the useful info. I sincerely appreciate it.

Sure... I vaguely remember I had to try to format as NTFS first for some reason before I got it to properly format with entire 64gb fat 32. I spent countless hours trying to work out all the bugs with this card and exfat. Samsung states the Galaxy S3 phone is compatible with it... but there is definitely an issue with file structure once you start loading it up.

Quick update:
I ended up returning my Sandisk 64GB and replaced it with a G.Skill 32GB (Class 10) that was on sale for $22 from Newegg. Surprisingly, it came already formatted as FAT32 so I didn't have to mess around with it to get it working with CWM and custom kernels. Seems to be working great so far, and is plenty fast, so I'm pretty happy with the end result. I guess it might have been nice to have an extra ~30GB, but I mainly stream all my music/video anyways, so I'll have a tough time even filling up this new card.
Thanks again to everyone who gave me their advice and input on trying to get my first SDcard formatted correctly. Even though I wasn't ultimately successful, I sincerely appreciate everyone's time & effort.

[Q] 64GB MicroSD Woes

Hello everyone. I have been having issue after issue with this 64GB MicroSD I got recently. I bought it at a local Best Buy the other day (there was a sale going on; $49). It is a SanDisk 64GB Class 10 MicroSD. I got home and formatted the card. I formatted it in FAT32 with the HP USB Format Tool that I always use for SD cards. Well, the moment I put it in, it said that it was damaged (occasionally said that it was blank). I tried removing it and reinserting it, and the same thing. I have tried putting it in a different GSIII as well as a Droid Razr, and same. I tried reformatting with the same tool, but this time doing a long format. Same problem. I also tried EaseUS Partition Master. Same problem. I have also tried using a live build of Parted-Magic. Same problem.
I am starting to think that the card is a dud, except for two things:
1: It works fine in my PC. It reads the exact amount free, it shows all of my files, and it let's me play them with no issue.
2: It shows up in Clockworkmod just fine. I can back up to it and flash from it with no problem.
I am really just left here scratching my head as to what the problem could be. I made sure that all of the settings are correct each time I formatted it. I have tried switching ROMs and still get the same problem. I have tried just about everything that I can possibly think of to get this card working. I am hoping that someone can help me with my problem.

You can call them and they will send you a new one, I did it about a month ago.
I was having similar problems.

Do you think it is a problem with the card? If so, I am still within my return limit at Best Buy. I can just take it there instead of waiting on a replacement. Just wasn't sure if it was the card or something I was doing.

It's a problem with the card. I had the same problem with a 32Gb card from Sandisk. Files could be seen for a day and then disappear! I could tell the camera app to save to the card and that would also work for a while only. Fo/ders create on the card via the computer would do the same. In one situation I created a folder on the PC, copied a film to it, viewed the film in my phone add took some still from the film. The next day the film and folder was gone put the still -stored on the internal memery- were still there.
Contact sandisk. They must be aware of the issue.

OK. I went to Best Buy and exchanged it the other day (lucky I bought it when I did; they marked it up to $99!). I am still having the same problem. I am not sure what I am doing right. I have been formatting and copying the files while it isn't in my phone. I am using my card reader in my desktop. Could this be the problem? Am I able to format it while it is in the phone without using the phone's format tool?

First you use the tool to format the card to fat32. Once you do that you are to install it to your phone then use the phone to reformat the card again so the phone can use it. Card will have issues with phones when you format it with the tool. Your suppose to format it with the phone as well after for it to properly work. Good luck

Just thought I should post on here and let you all know what my problem was. I got it all sorted out and Play Music is showing all of my music. My problem was that EaseUS defaulted the partition as a "logical" partition. This was leaving about 75MB unformatted, and Android didn't know how to handle that empty space. After changing that to a "primary" partition, I have not had any problems. Serious derp on my part. Lol

I found that if you format the card from in the phone and then transfer data, you shouldn't have any issue.

[Q] SD card just died

I've had a 32 gig micro SD in my phone for a while now. I recently took my Siii out of my pocket only to find that it says the SD is unmounted. Odd, but not unheard of in the world of custom roms (paranoidkangdroid 2.something, rather recent though, 4.2.2 JB) So i do the sensible thing: Run into the storage menu, and lo and behold, its not registering. I pop it out and in, not registering. I reboot, and the damn thing still isn't registering. Then I take an old 2 GB micro SD and try it. This one worked just fine. 32 gig however does not. I move to my PC. Pop it in a micro to regular SD adapter, and the computer doesn't mount it. It does mount every other microSD of mine though. So can anyone tell me what the hell happened, and how I can recover my stuff?

Actually you can't, your sd card is corrupted and it's known to happen with this device that's why I always keep a weekly backup on my computer with everything. Especially the ones ordered from amazon the high capacity ones as far as I've seen.

Is the SD card damaged or can it just be reformatted with a card reader on a PC (fat I am assuming)?
I was about to start using an SD card to backup the internal storage. It doesn't sound like this is the best option and backing it to my PC would be better.

My set up to start was cleanrom 6.2 with envy kernel running fine for a week. I had my sd card disappear today twice. PNY class 10 32gb less than 2 weeks old from best buy. Popped it in my pc and it was recognized no problem. So I transferred my data, formatted in fat 32 popped it in phone, no problem. Transferred data back and was Ok for a few hours. Swapped my battery for a freshly charged one and upon boot, phone said the card was damaged, to reformat it. So, I pulled it out and popped it in my pc. Pc said card was damaged. I opened a command prompt and ran a chkdsk /f and it fixed an issue with the file system. I then proceeded to restore my cleanrom 6.2 backup. So far so good. I am thinking it had to do with an app, but I can't be sure. Upon googling this, it seems that some people have had an issue with external sd cards with this phone.

I'm not sure exactly what brand or model you have for your SD card or when you purchase it. However if its a SanDisk and it was purchased before December 2012 there's a chance that it was part of a bad batch. I had the exact same problem with mine I have a UHs 1 32 gig SanDisk. I read somewhere on the internet that there is a known problem with SD cards from that company built before December. When I spoke with SanDisk they confirm that and said the newer batches have been corrected. Long story short if you're using an ultra high speed or for that matter any card by SanDisk call up there customer service explain to them the problem and they will send you a brand new one. The entire process took about a week for me.

Did you try my suggestion? Ive recovered numerous files using a linux live cd and/or a mac. Try putting the card in a network printer or mem card reader if linux and mac os isnt possible. Ive recovered my files, including those from a 16gb micro sd card, using those methods in the past.

Okay, so it works
Alright alright, i didn't expect this to get many responses. Anyway, it now works. It appeared to be fried, my mac, PC, ubuntu machine, and OG droid wouldn't even recognize that a card was inserted. Nor would my GS3. My solution? after turning it on and off a few times, I just left the card in it and set it aside for an hour. Lo and behold, it now works. The SD now works. It was fried, and is now unfried. I don't know how, I just guess I am lucky. Or aliens. Either way, I am happy. Not gonna jeep anything more than music on it though... Ah well, thanks for the help XDA!

If I were you, I'd back up everything on that card to my pc, and exchange it if under warranty. If not, chuck it, and purchase another card.
Not worth taking the risk again.
Consider yourself lucky so far

I read about the SD problems after just getting the S3.. decided to get a different brand card from the store.
