unable to mount sd card

I am a newbie to rooting and trying different roms. Today after trying different roms, my phone no longer identifies the sd card. I have tried almost everything but I am unsuccessful. Any help will be grateful thanks.

What rom were you on when the problem started? Do you have a card reader that you could put the sd card into, and then into your computer? Does the computer recognize the card? I would see if you can format the card with your computer, and then put the card back in the phone, and see if that helps. Just keep in mind that formatting the card will completely wipe it, so if you have any important stuff that you need saved, I'd copy it to your computer before formatting it.
Did you try just taking the card out of the phone, then putting it back in? Does the computer see the phone itself when you plug it in to the computer? If so, can you view the card from the computer when you select "disk drive"?

Dont have a card reader and I was using Mikfroyo 4.6. When I flashed back to the original rom that I have been using for the past couple of days it no longer recognizing the sd card

Strange. So the phone doesn't recognize it, nor does the computer when you plug it in via USB, correct? Do you get a green charging led when it's plugged in to the computer? Do you happen to have another phone that uses an sd card, to put your card into the other phone? If not, and you're unable to format the card using the phone, then I'd try to get a card reader. Either borrow one from a friend, or buy one. They're usually pretty cheap. If neither of those options are viable, perhaps see if you could try another sd card in your phone for a sec, if you have access to one. See the phone reads a different card. Hopefully you'll be able to try one of those options. There is a thread laying around here somewhere, by Calkulin, and it has instructions on how to fix broken sd card and / or usb port. I'll have to look for it, but I know it's around here somewhere. You may want to search for that thread.

i will look for the thread..I reset my phone but not back to stock and still unable to read the sd card

[Q] USB and SD not recognized

Need a way to access internal memory so I can fix my usb or sd card see following for information:
Short Version:
USB wont work and SD card wont work so I cannot use the following method http://forum.xda-developers.com/showthread.php?t=695243
Long Version:
So right after i had backed up my rom i did a wipe, then the phone stopped recognizing my sd card. I took it to Sprint they couldn't figure it out, so i was stuck in Bootloader. yesterday i did a hard reset and wa-la i can now use my phone ...sorta. It will turn on I can access everything, but it freezes up and shuts off after 40 seconds (i got it to stay for 2mins one time) also it still will not recognize my sd card. I tried other cards still no luck and I know my card works because I can use it in my laptop. So i did a little searching on xda and found a fix, but i cant do the fix unless i plug my phone into the laptop and run a cmd prompt well now here is the other problem my computer sees the phone (listed as My HTC) but my phone wont recognize that it is plugged in. It will charge when it is shut off thats about it. Well back to xda and there is a fix for the usb, but.... I need my phone to recognize my sd card because the files will be on it. In short to fix my sd card i need usb and to fix the usb i need my card I am stuck in a horrible loop, so what I need is a way to access my phones internal memory so I can install the usb files on it so that i can fix usb then my card, then recover my rom.
Thanks to wall who help or at least try

Im not totally sure if this will help, but i know you can mount the sd card as usb storage in Amon_Ra and also in settings under "storage" or so i believe there are settings for mounting and unmounting the Micro Sdcard check those, it should be mounted in the settings for your phone to see it. hope i helped

I just had this exact same problem. Nandroid, wipe, flash, then stuck in bootloader spent two days trying fixes, unroot, root, and,had to turn it in. Luckily best buy has an awesome warranty.

thanks all... ended up replacing my phone, but if anyone ever finds a way to fix it let me know! Thanks again

I was really hoping that this thread would not dead-end. I've got what sounds like a similar issue...in addition to not being able to reformat my SD card (in Windows or in Android) due to it being detected as write-protected, but it's not write protected.
I'm really anxious to try the aforementioned thread to fix USB and SD, but I can't detect, mount, or format my SD card. Am I screwed?
*EDIT* Fixed the write-protection issue...working on the rest now.
*EDIT* Still can't format card through Android. Is there an ADB or fastboot command to format the SD card?

[Q] sdcard wont mount

Thought I would ask first... my SD card will not mount on my phone. Data seems to still be there but I have a notification saying "sdcard is blank or has unsupported filesystem." Tried to format but the card wont mount on the device. I've tried formatting in the android os and in recovery with errors. Does this mean the SD card is toast? Any help is appreciated. I'd hate to lose all of the data. Thanks.

At work right now and our computers are on lockdown, no external devices can be read. If I can access what should I do? When I tried repartitioning in recovery it said it could not mount dev/block/mm? ?? Or something like that, basically gave me an error. Any advice? Im about to just buy a new card.

You might just need to reformat the card. Sometimes the cards get corrupted. You might even still be able to access and backup the content on the card if a PC will read it. If you have WIndows 7, it might even offer to repair errors on the card. That could also get it working. I'd say reformatting it is a good idea either way.

i just had similar error... try removing and reinserting card. if that doesnt do it reboot into recovery and depending on the recovery you are using go in to mounts and try selecting "mount sd card" that last one fixed my issue.

I ended up just buying a replacement 8GB class 10 card (wanted a higher class card anyways, this gave me an excuse to buy one ). I was able to retrieve the contents of the SD card by mounting it in my computer (vista 32). I didn't try reloading it into my Evo cause now I don't have a need for it. Thanks for the responses though, glad that you guys are here and willing to help. :thumbup::thumbup:
Sent from my Modded Evo... It's easier this way.

SD card mount problem please help

I've been searching all over for a couple days now and I can't find any solution only people with similar but not exact same problem I'm having. Out of the blue a couple days ago the fat32 partition on my 32GB class10 patriot SD card unmounted and won't mount at all. However the ext4 partition mounts just fine and continues to work as it always has. I also can't plug the card directly into my PC because the adapter that came with the micro SD card appears to not work. My PC doesn't think there is an SD card in it. I tried it with a known good SD card (the 16GB samsung SD card that came with the phone. Which when inserted into the phone mounts and can be used like expected. No new apps where installed or changes made to my phone or the SD card before it stopped working correctly. The same apps and what not have been in use for as long as I have had the 32GB SD card. In fact the currently in use version of CM10.1 has been is use for the last month with no issue regarding the SD card. When I remove the card a notification shows up telling me to insert an SD card. And when I insert the 32GB card the checking SD card notification shows up an a second or two after the SD card is safe to remove notification shows up as if I had told it to unmount the SD card. If I tap on mount SD card in settings the same thing happens. And it also happens after a reboot. CWM can't mount the SD card either. What can I do to fix it so the fat32 partition is usable again?

Have you tried formatting the SD card in recovery?

As I said I can't mount it with CWM either. The card contains the data for my mSecure passwords as that app was forced to the SD card due to JB changes in android so I can't format it until I can recover the data on it. I need a solution to access the data before I can reformat it assuming that it needs to be reformatted. The SD card was supposed to be this fail safe thing and I didn't need to make backups of it as it was the backup storage stuff. So now I'm all freaking out because I can't access it for all the backed up data on top of the data for one critical app that was forced to reside on it. The good news is that only a few apps data is effected by this the bad news is those apps were all very important. I just don't understand why this has happened. And if using a cloud source such as box will be any more secure and safe than using the SD card in light of this; now I don't trust not losing data in the future on a source that was supposed to not have this sort of thing happen.

Maybe the SD card just went bad. Sorry I couldn't be of more help.

No problem, it's a problem no easily solved, and is a long shot finding anyone who will be able to help. I looked at dozens of sites and forum threads and all sorts of other stuff from goggle searches and couldn't find a solution to get it to mount in either the phone or on my PC to recover the data from it and find out for sure if it is a bad card or not. It might still be under warranty. If it's not I'll be ticked considering how much it cost and how little time I've had it.

Try installing Recuva on your PC, if this program doesn't work for you then you might wanna try another more advanced recovery program like R-studio v6 (Shareware) which is easy to use since it's GUI based.
or testdisk-6.14-WIP (Freeware) which includes testdisk_win.exe for partition recovery and photorec_win.exe for files and media recovery, but it's kinda complicated since it's based on Command Prompt or DOS! so you need to google for a guide for how to use it.

Wow I somehow never got notified of this post seeing as I'm just now noticing a reply from months ago. Yes I still can't mount the SD card. I took it out and returned to the stock one that came with my phone. I still have the card as I need to recover the data from it and if not possible wipe it somehow so that I can warranty exchange it. Please do let me know what your solution is so that I can try it and see if it works.

Refresh my memory on what the problem was. This was a while ago lol.

The SD card won't mount in my samsung epic and my windows PCs. This was a sudden without warning signs and with no apparent cause. One moment it was fine and the next moment poof. I was looking for a solution to gain access to the files on it to recover whatever I can and if possible repair the card so that it works again. Assuming that it's not a failure of the card itself. It is within the warranty and well within the life expectancy of it. So I suspect it is not a failure of the card itself. I have the option of using ubuntu or other USB stick bootable options for tools as needed.

No reading sd card

Hi. Picked up this phone a week ago. I love it. I put a sd card in from another phone. I got it in and it sees it but I cannot read it or format it. Does it have to be a certain sd card to work?

Download file Commander and format sd card, if it won't do it, connect the SD to the PC and format it on NTFS:highfive:

I tired pk unzip but there is no format option. I formated the card with my computer like you said but it still doesn't see it.

Can you see a popup informing you about "SD Card" inserted.
You need to complete that step from the notification menu.
Select it as Media Storage for using it properly.

Hi
So try to format it as FAT32

I do get a notification but everytime I use it, it crashes. I tried the FAT32 format but still get the same results. I am trying this with two different sd cards which work fine in my old phone and laptop. I think it's the phone. Some googling resulted in Xperia phones not being able to read sd cards properly.

Ok so I have an idea, have you been on an airport or over a metal detector? If yes, it means that your SD card or phone got demagnetized (happened also to me with old phone), so buy a Sony SD card that resist to them :good:
