Question about SD cards not reading everything

Hey everybody its Cardi Lyone here with a pondering question for all you super developers. i recently bought an SD card off of ebay that was a 32gb for my htc evo. granted it came from china so i got it for round 10 bucks but thats not the problem. the card DOES WORK AND read at 32gbs when entered in the phone and threw my laptop; but when i try to copy everything on my stock card to that card everything usually everything reads apps ect, but my music and pictures. i have no idea whats going on thought it was kinda weird. looking for a little feedback before i go out and spend good knows how much for another 32 gb card. thanks for reading and helping.

Hmmm....I don't have any idea, but did you try reformatting it as FAT32? Sorry, that's all I could think of.

The sd card is a fraud. Its not really 32 gigs.

sd cards can be hacked so they say they hold so much data but what it does is just keep writing over the same blocks. There are programs to test the actual size try... h2testw... google it, its a free program it takes awhile since it tries to read and write the the full amount of the card to see its real capacity. my guess is that you have a 512mb card hacked to say 32gb... sorry man

i was figuring so, guess i didnt want to think it was true. but thanks for all your help on the matter. if anyone has a 16 or higher laying around leave me message maybe we could work something out!

16gb isn't working anymore? HELP!

Well my 16gb somehow got curropted and won't be read by my phone or computer how do I fix it?

Seems like you need to reformat it, but you'll lose all your data.

I don't care about data lol how do I reformat it? With what program
Sent from my PC36100 using XDA App

1. If you can still get into recovery, you can navigate the menus and format it there
2. Plug it into your computer via micro sd adapter, right click it from my computer and click format, it'll warn you about losing data, click yes, may take a minute or 2 either way.

my computer wont read it but i will try through recovery

Alrighty, let me know how it goes.

didnt work it just says unavailable when i turn phone on. like as if it isnt in.... anyting else?

http://undeleteplus.com/ Other users have suggested that.
1. On your pc, it isn't even showing up as a drive? [removable G, fro example?]
2. In recovery, under advanced, and under partition sd card it acts as nothign is there?

Im having the same problem as you bro except its with a 2GB when I put it in my phone it automatically says "blank sd " and I try to format it but it stays unmounted. And tried a microsd card reader and it will pick up but makes the computer super slow and unresponsive and can't get it to format there either.

Try rebooting your computer, give it 5 minutes to run, try inserting your sd card, and give it some time to load. If the memory card is corrupted, it takes extra time to read...that worked for me regarding that problem.

I had this happen with my Wintec 16GB card, I managed to find some recovery software online (can't remember the name right now, sorry) and used that to recover some stuff but I couldn't get everything. I ended up formatting it with this from my PC and sent it back to Newegg.

Yeah, that's the one I decided to be cheap too and the reviews were good at the time but now I'm regretting it. Newegg has a pretty good exchange policy though if it dies. I just hope my second one doesn't go out too because then I might have to go through Wintec when it does.

[Error] Sdcard unexpectedly removed

This has been the second time getting this error on SG3.
The first time I checked if the card was corrupted by putting the sdcard in the netbook, it was recognized and displayed all the folders. Inserted the card again in the SG3 and it wasn't recognized, rebooted into recovery and fixed permisions and cleared cache/dalvik and rebooted. The card was back up and everything was ok.
Again happened today, tried the same thing and nada Now it also says "Sdcard blank or unregonized file system" in notification and it then prompts for format confirmation upon tapping it.
I've googled and oogled and keep finding different solutions, some I cannot try now since I'm at work. One of them suggest to move all files to PC and format the card, I'll give that a shot at home and see. Another was to update the firmware, but on the latest L13... Apparently, this has been ongoing for sometime and there is an open issue in google for this.
http://code.google.com/p/android/issues/detail?id=19722
http://code.google.com/p/android/issues/detail?id=9736 - Originally opened for LG Ally, but HTC and Samsung users have also reported it on the same issue.
Anyone else encountered this problem in SG3?

Happens to me all the time. Sometimes it will just continue to prepare then unexpectedly removed pops up, then that will cycle and kill my battery. I just got a new SD card hoping that would fix it but it did not.

I'm researching like a mad man! Found a few tools but most are for HDD and not microsd... found the one below that is supposed to detect the card/drive even if it's not mounted or has a drive letter and revover the file system, repair partitions, recover ALL file types, etc but nada
Had a few important fotos, my most recent nanroid, my TB folder, that last one hurt the most.
I didn't back up after the first "fix" cause I thought it was a one time things, never heard of this error before. Lesson learned

If your computer can see it and you don't mind losing data do a low level format on the SDcard
Edit: my SDcard started liked yours but got so bad i couldn't use it at all with my phone, I'm fact Windows couldn't even see it i had to use Linux.

Mine is in that state right now, XP won't pick it up, booting up Win7 PC to try it. My Nikin S70 detects it but it says unusable and won't format it either.
Guess my only option is to partition the netbooks HD and install Ubuntu on it, this gave a good excuse to try it out lol
Found this post that gives some pointers and explains the linux part.

ugggg...... my sd was just totally killed. Windows will not even recognize it now and it reads as a blank SD in the phone. did you figure anything out OP? Mine is 32G sandisk class 10.
this sucks

Same thing happened with me D: did anyone find a solution other than losing all the data on it?
And since I see this thread is fairly new, did everyone else happen to be on the leaked Jelly bean build? It happened to me after the phone rebooted while on the leaked ROM

Apart from the info already here, nope... I need to buy an external sd reader that gets a drive letter assigned without the card and try to force mount on win and run chkdsk, it's the only thing missing. Not even Linux picks it up! Not even force mount! This sucks and seems to have been a problem in android for some time now...
I did order a sandisk 32GB Ultra, but would like to fix this one. Might use it for the camera or give it to my better half for their TF700.

Next time it happens and your pc still happens to pick it up, run a chkdsk on it. Do not format it. It might prevent it from happening again...

i was not on the JB leak. Beginning to think this is a hardware problem, so last night i unrooted and am going to the sprint store today.
I did try force mounting, chkdsk and everything else i could find but nothing worked. fortunately i am still able to return the SD card because i have only had it for a week.

My 64gb class 10 just started doing this after i formatted it to fat32. I am wondering if formatting could be our problem.

Yes and no...It was stated by some members that there was a write-up saying that you shouldn't format your card because this would deduct part of it's useful life.
I never formated my card, it was inserted as soon as I bought the phone and been using it since and never formated it.
I'm going tonight to Wal-Mart and getting a card reader and seeing if that helps in fixing this. In an earlier post I attached a link to an old thread that gives a solution that seems to have helped others.

FYI, just got back from the store and it is definitely failure of the SD card reader. They tested it and my new phone comes tomorrow.

Sprint store? How did they determine it?
I used another sdcard that I had, 8GB, and the phone read it ok...
Edit - then does this mean that there might be a factory reset on the card reader in the SG3? :/

all they told me was that they inserted another card and it happened. Mine also fried two cards so far, so it is definitely pretty bad and i was confident it would fail any test they gave it.

hm... I'll clear up a 2GB one I have lying around and see how it goes before using the 32GB Ultra.
If it happens again, I'll visit the Sprint Store on Saturday.
Do you have TEP or was it covered under manufacturer warranty?

i do have TEP but it was covered under manufacturer warranty. took over an hour, but worth having the ability to use an SD card again

Thanks on the update.

Hey guys
Been reading this thread, having the same issue.
Actually the only reason I post because I'm troubled of the error other then having an actual problem, this error been spawning up for me for quite a while, though it does seem to work perfectly fine.
You think the SD card could just Die one day ?
I hope you guys could determine if there's a factory defect in the SG3 or the Card, I got the international GT-i9300, I hope i won't have to return it, since the shop it was bought from is located at Poland and I live in israel (let's say that handling via warranty is not an option).
Need to check perhaps with samsung if they know of any factory defects regarding microSD card readers, My SDcard brand is Sandisk 32GB ultra class 6.

I fixed mine by completely removing the battery and putting in sd card then boot up. Sounds dumb but it worked.

[Q] my 64gb card = 2tb?

So I have a 64gb sandisc u1 card, in partition magic it shows the usable space as a partition in between a small set of unpartitioned space and a large set.
All space = 2tb
Thoughts?
Explinations?
Exploits?
Sent from my SGH-T889

sounds like you might have picked up a fake card chinese formatted.. i'd backup anything you have on it, delete all partitions and redo it. see what it comes up with then..

No, its from best buy. I dont buy transflash off ebay. Its 59gb in compasity currently. I didnt do any mods. Im asking about possable mods, or as I have infered, that theirs nothing. It shows 59gb in windows. Only partition magic shows 2tb full withh all the rest of the area being unpartitioned and unformated space

What are you using to see this 2TB? A PC? Format the card in your phone. As to hacks/mods that would cause these mods.

His post above yours says what he's using. Partition magic. Either way, I'm guessing the issue is the software if Windows shows the true value. If you want a safe piece of mind, back up the data, and exchange it best buy. If the new one reads the same issue, then it's the software. Cause no way 2TB would fit a microsd.

I dont belive its the software because other trans flash didnt have this issue.
Yes pc

Have you tried using the software to read other 64GB cards? Either way, if everything is working fine, and you download other software and everything but Partition magic reads it at 64GB, then just keep it.

It's not a 2TB card. As people have answered you, either the hardware is borked, or the software is confused with that card (make, model, when it was made, etc). Just because other cards have worked fine doesn't mean the software isn't confused. Just because you bought it from BestBuy doesn't mean the card is good.
People asked about eBay because many of us have been burned buying a card that is formatted wrong so it looks like it has a higher capacity than it really has. Either the software you are using (that exact edition, set up, installation) is giving you possible options to make computers think it is higher capacity (which will not do you any good), or that card could be flawed which is confusing the software into being unsure of it's total capacity.
The only exploit you could do is try using the 2TB formatting and showing people your super cool 2TB card (which would destroy files that were placed in non existent sectors). I don't recommend doing that, as it wastes the card.
I haven't really said anything that anyone else hasn't been talking about, but these seem to answer anything you may have been asking (since technically you never formed a full question). So I think your question was answered, you may have just not asked what you meant to.

Correct, but I do not belive the card is flawed. I agree with the rest though. And if my question dosent seem fully developed I appologise

SD Card issues

So Im going on vacation here in a few days and was downloading my Amazon prime music to my 64 GB SD card and then randomly after I was done downloading it it gave me a error that said the SD card was blank or had file types that were unsupported. Now when you go to the storage location under settings it would act like the card was not even mounted and would tell me to reformat it.. So I've done that twice and re-downloaded and still the same issue. Now this happened on my Note 3 with a compactly different SD card.
The SD card in my note 4 is brand new is there something Im missing? Its getting super annoying. Because when I have apps to the sd card and pics you cant seem to retrieve them. Is it possible that after I use 32GB of space on that card that anything after that corrupts? Pretty sure that sounded stupid!
I had a issue on my camcorder that i put a 64 gb card in my camcorder when it stated that it supported up to 32gb and anything after that corrupted,
Any suggestions>?

Sounds like you're using a counterfeit SD card. They're usually a smaller card (8GB or something) hacked to make it appear to be a larger capacity (say 64GB). When you put the card into a device, it reads as the larger capacity. When writing to it, it can only write up to the actual size, then loops back to the first sector on the card and continues writing.
So basically, in your case, the card may actually be 16GB or something. When writing to it, the card will fill up the 16GB, loop to the first sector, and write over what was just written. It'll do this 4x! (4x16=64). So this will corrupt your card and give you these problems.

I prefer Sandisk, Samsung, Sony, or Kingston. Buy at a brick and mortar store though. Don't buy online. Well, you can buy online, but do it from brick and mortar store websites (like Best Buy). It's the only way I've found to guarantee not getting a fake. Fakes are especially on Aliexpress, Amazon, and Ebay. Avoid those places for sure.

Yeah, high possibility it's fake. If I had pics of it, I could probably tell, but I'm not going to ask you to go through all that trouble.
Instead, read this:

Also try this if you want. It's an app that tries to detect the authenticity of your micro sd.

Best Buy only sells genuine cards, and sellers on their marketplace should be authentic too. You should be safe, but I would've gone with whatever was on sale there. No matter what, it should be real.

Sorry, but I don't know anything about unlocking. I only know about sd cards because of personal experience. I've bought many cards over the years and many were fakes or crapped out on me in under a year due to poor quality. I've learned where to buy and where not to, trustworthy and untrustworthy brands, etc.
