External SD card doesn't work??

I can not get the external SD card to work. It worked at first when I got the phone but now nothing happens when I try to mount it....I can format it within the phone and it even shows up as the folder "sd" within Astro but I can't move files to it at all on the phone or by drag/drop on the PC...
Anyone else with this issue or a known way to fix it?

Have you tried a different card or tried the card on your PC? Do both the internal and external storage drives come up when you connect to the PC? My Captivate once gave me a no external SD message when there was one in there. Took it out, reseated it and it was fine.

It worked when I put it in the first time but ebert since I took it it when doing a restore with odin 3 it doesn't work anymore not even with stock firmware

Is this a name brand card (Sandisk, Kingston, etc?) or a noname special? The cheap cards have high failure rates. You could try a PC USB reader, but you may have a dud.
Try a friends card and see, just to rule out your phone SD port.

32gb sd card

Hi guys im having an issue with a 32gb Kingston sd card, whats happening is that everytime i add files to my sd card from my computer it will show them to me that they are there. But once i put the sd card in my phone the new files i transfer wont appear :/. Ive formatted my sd card already like couple times and still does the same. Never did that to my 8gb card, and top of that when i transfer all my data from the 8gb to the 32 only half transferd and when back n fourth doing it folder per folder and just wouldnt show anything on the phone. Any suggestions, thank you

Going to take a guess and say you're on CM? If so I had problems with my 32GB too but on stock roms it works. I had to get a 16GB to use under CM. I'm not sure of the problem but there was my fix

Are you rebooting the phone after putting back the microsd? Sometimes that works.

As matter fact havent tried on Cm, im on MIUI right now. But im giving it one more try with the formatting see what happens if not will go to Eagle Blood see how that goes.

Yeah im since i noticed my sd card wouldnt show up unless would have to reboot. some files have been transfering but like awhile ago i d-loaded the files that needed for the game Modern combat 2 and after finished i rebooted or just quit playing and tried playing again and have to be redowloading the files over and over again since nothing stays on my sd card :/

That sucks, sounds like a bad sdcard. You still got the receipt?
I got my 32gb lexar class 10 with USB SD reader for just under 50 and its been issue free. Never liked Kingston products.

Tried formatting it using the phone itself? Miui is based off cm7 so that could be the issue as well.

Won't let me format it from phone since as soon as I put it in tells me "safely to remove card now" so kinda like automatically ejectects itself when I put it in. N got another problem :/ I bitlocked the sd card in my windows 7 laptop and as I was transferring files my wire was loose and we'll lost the connection and of course gave me files transfer error. But the problem now is that since I bitlocked the sd card won't let me get in it anymore, even though i put my password I put for the sd card. Just says something error with files and blah blah ;/. Can't even format or or anything anymore ;/

But i still did it and when i mounted it on my windows 7 i formatted again and this time showed me the 32gb size . So now its working properly.yeah buddy.

Moving from Weapon X to Miui rom my sdcard was detected fine but then after a couple of days of using Miui I wasn't able to open up sdcard when connected to my pc. It shown that usb is detected on my phone.
It only work when I restore back to WeaponX. I tried flashing different Miui roms, EagleBlood and PhoenixBlood. None detect my sdcard on pc except for WeaponX. I also tried to format my sdcard. Didn't work.
Anyone got any suggestion??

Try reinstalling ure usb drivers or not just restart the computer that would help with me. Or have you tried it with a card adapter?

If you've tried it both with the USB cord and with an sd card reader, it might just be a bad sd card. This happened to me with a Samsung 16gb. I couldnt add or delete anything on it. Simply had to get a new sd card. Try out Lexar or PNY if you want a good one.

Why cant i use my sd card?

I have a 16gb s3 and 16gb SD card I wanted to either move my music or apps but I can't figure out how my phone recognizes the SD but for some reason its seems unusable. Is there some setting I'm missing or is my SD card corrupt?

not sure i understand your question exactly... but i can say that certain programs are not able to utilize the sd card in our phones. this was new for me coming from a motorola. the way samsung refers to the internal "sd card" vs your added external sd card is different so a number of programs will look at the internal memory as the SD Card instead of your actual SD Card.
that said, you can bypass this with a program the binds the directory on the internal storage that the program is looking for to a directory on your SD Card.
search my posts... i posted the link to the program (not mine) in another thread. it's working great for me with MOG. before, all my music had to be on the internal storage for mog to read it. now, with the directory bind program i have all my music on my external sd card and mog reads the files just fine.
hope that helps!

Well I downloaded app2sd and it says this device does not have a primary external storage. It does not even recognize my sd

No, since the OS won't allow apps2sd because it uses MTP

Read this below.... The device uses MTP so it will not see your external SD card in the slot by ICS design...what you want it the UMS the USB mass storage where the device used the SD card to save data...but the Samsung now has 16GB internal storage so it presents a problem...
This app was written to resolve that issue... Also there is a link to explain this deeper than what I am doing....

Is there anyway to do this without rooting really don't feel like rooting right now
Sent from my SCH-I535 using Tapatalk 2

Well I figured out how to get files from my Mac to my sd card using android file transfer. I transferred some videos and the stock video play found them right off. The only problem is that I can find the folder that there in using file manager. Its like a ghost SD card I can't find it anywhere but at least I can transfer and delete them now I just need my computer to do it.

My SD card is a zombie

so i keep deleting files from my sd card but they keep coming back.
i've pulled it out and plugged it to my laptop and it says files are protected? didn't know micro sd cards can be protected ( no physical switch on the side) nor did i find anything underneath properties tab.
i went as far as formatting it while mounted, all files delete but when i restart the phone, they all come back.
i like to know how i can make this go away, kindly advise. thanks.

What files are you deleting? Android puts certain files and folders on the SD card automatically

nothing specific. pics.
somehow they became write protected and i can't get it out of it.
need a new flash adapter , unless there is a way to remove write protected stage while its mounted to my phone?

Have you tried using an file shredder utility on your PC to delete them? Past that I would say its a mystery.

This happened to me a few times before as well it except I was trying to format the card instead. If I remember correctly it was because of some type of setting having to do with developers usb connection. I'll edit this post if I remember/find out what I did exactly

still looking, any one have a solution for formatting a write protected micro sd?

Are you trying to format it or delete specific files. If you want to format it find a hex editor, put a normal sd card and steal the hex from the normal sd card and put it on the 1 you're trying to format

Hi, trying to either remove protected content or format it, which ever way possible.
define steal? just downloaded freeware hex editer xvi32. not sure how to operate it though.
how do i steal the hex from another sd card?

I can't reproduce the problem so I'm unable to find the solution again. Sorry. That and I've also lost the 16gb micro SD card that had that problem. I'm using a 32gb now.

called samsung and they'll do a warranty exchange on it. problem solved
not sure how the micro sd locked up but it did, strange things happen i guess. i even tried multiple sd adapters and devices and still got the same error.
thanks everyone for their feedback.

[Q] Can't Format External SD-Card

So I think I've tried absolutely everything (that I can think of at least), but I can't seem to format my External SD Card. I've tried from CWM, from Windows 7 from and from an old Windows XP machine. I've when connecting to the computers I've done a manually deletion of everything on the SD-Card only to un mount it and re-mount it and find everything is still there. As well as right clicking on the drive and selecting format and then un mounting and remounting and finding everything is back. What is really weird is that everything indicates like it works but once I unmounted my SD-Card and then remounted it, it just comes back. I've also gone into root explorer and tried deleting it from there. If anyone has any other ideas I would sure be grateful to hear them. Thanks. Also my phone is CM 9.1.0 with root (obviously).

How are you mounting your sd card on the computer? You are only using your phone or you have an external reader?
If you are only using your phone the issue may come from there and you should try an external reader.
Also to format it in windows try right clicking our computer>manage>manage storage and there find your card an try formatting it.

and a video http://www.youtube.com/watch?v=6z1Tu9l8WNc

@kishke I'm using my phone to mount my SDcard, I don't have an external SDcard reader on me at the moment. I could definitely give it a shot. I'll update you on how that goes. I'm also going to try the comment below as well. I did try and do a windows format and that didn't work either. So definitely stumped on this one.

Discovered some new info
So I found out that my external SDcard isn't writeable... but I checked the permissions in system/etc/permissions/platform.xml and everything looked good. Any different ideas out there?

Yes. Sometimes you can pull data of a card that is not writable.
