Can't read sd card. - HTC EVO 3D

I was playing around changing prl's and on my last reboot my phone stopped reading my sd card. I've did nandroid backups, pulled battery and took out and re-installed the sd card. Nothing. Anyone have any ideas on what I can do?

I don't think it's my card because I can still flash roms that are stored on my sd card.

I am using twrp recovery. My phone won't go into disk drive when I plug it into my pc, but if I go into recovery and toggle sd card, my pc can read the files on my sd card.
I could sure use a little help. Or at least a push in the right direction.

That is a strange issue. If it were me, this is what I would try:
Use a card reader connected to your PC and copy all of the files over to your PC. Make sure you have your folder view set up to see hidden files.
Next, format the SD card. (you can use this free program "SD Formatter" https://www.sdcard.org/consumers/formatter_3/) or just use your normal formatting process.
After the card is formatted put it back in the phone and see if it can read the card. If it can, then copy the files you backed up on your PC back to the card.
If it can still read the card after putting everything back on, you're golden. If it can't, then there is some app or file on the card causing the problem.
Good luck and let us know what you find.

thanks for the advice mvansomeren. worked like a charm. i have no idea what happened. i changed a prl file rebooted, was too slow so i did the ##775# and i saw that i couldn't find my old prl file. i went to check for the file and couldn't find my astro. lol. then i noticed that the phone wasn't reading the card. well, if it happens again i'll know what to do. thanks again.

Thanks for letting us know how it worked out. I'm discovering that the SD card is the root of a lot of strange issues. I'm not sure if data is getting corrupted somehow or the quality of the cards is questionable but now, whenever I have a weird issue with the phone, the first thing I do is pull out the SD card and see how the phone behaves without it. If the phone returns to normal, I know its something to do with the SD card.

+1. It's happened to me several times. Also a good idea to back up the sd card often. Saved me many times.

Q. SD Card damaged?

I installed CM7 recently and flashed CM7 OTB newest test 2.6.35.13 kernel. it's been great until a reboot I did just now...it says damaged sd card, reformat blah.
is there a way to revert it? I can't format my sd since I have important documents inside...
I had this problem too. I just pulled the sd card out and put it back in a few times and it started working again
Try it, can't hurt. Maybe I was just lucky though.

Oddly enough I have the same problem. No matter what my sd looks jacked. I mounted and saved to a pc but no matter what it won't save anymore and won't format.... Odd.
I'm terrified...I can't get into recovery and even if I do I have no access to files. Can someone tell me how to fix my sd card?...I need to recover my files inside.
Use a card reader and save your **** on a pc. If you can at this point.
good day. using xda premium.

[Q] SD card back up to PC

So I decided to try an experiment and transferred everything off of my sd card to my pc. I rebooted everything and then moved everything back to my sd card. I can see all the files through a file manager, but can't figure out how to actually load everything.
Any ideas??

The hell? What's the purpose of any of that?

I moved everything off of my sd to my pc for a backup and when I moved it (my entire phone..I just dragged and dropped the whole folder) it didn't actually remove anything from my phone it just copied it. So I still had a copy of everything on my phone.
Is it possible that you somehow modified all the contents of your phone folder before you moved it back to your phone?..I'm just thinking out loud really, maybe it will trigger your memory, or give you and idea of what went wrong.
What version of windows are you running?
What rom are you on?

FIX - Corrupt SD card from S-Off

I skimmed through the general thread and FAQ and couldn't find anything on this, so I figured I'd post this!
I didn't have a smaller SD card and figured nothing bad could happen, so just used my 32GB SD card and it boinked out. Thought it was done for...until today! Here's how I got it to work.
1. Make sure you have your SD card in your phone.
2. Boot into your recovery (I used TWRP and haven't tested this on Amon Ra.)
3. Mount your USB storage and go to "My Computer" to view your storage drives.
4. Your SD card should pop up as a Removable Disk that has no info. Simply format the drive, reboot into your ROM, and bam! Fully working SD card
If anyone can test this in Amon Ra and let me know if it worked, be much appreciated, thanks!
easiest way is this:
do your s-off. boot into amon ra. goto the options and format the SD card right then and there.
you're supposed to always format the card right after S-oFF, or else the slot tends to not work right or something. this is pretty much why they said to try to use an extra backup card instead of using your own personal one, so ya don't have to lose everythin
Whoops, just realized I posted this to development lol. Sorry to any mod, if you could please move it.

I couldn't even get S-Off to work, lol. I tried for about 30 minutes and ended up with a "dead" SD card. My recovery didn't even see my SD card, I just mounted my USB storage for S&Gs to see what would happen.
Something I find that really helps as well is to make sure you don't flash the Gingerbread hboot when using the S-OFF program. I didn't think it would, but it did manage to give me SD card issues until I flashed a proper ICS hboot.
I'm only mentioning this because after I S-OFFed and got the SD card issues, formatting it did nothing at all to fix the problem. Only after I got the right hboot did everything finally start working again.

I didn't even get that far lol. S-Off didn't work and my SD card was a dud afterwards. my computer would see the drive, but wouldn't do anything with it. My phone just said "blank SD card" and couldn't format.

The method I posted. Just went into recovery, mounted USB storage and formatted my card from Windows. The only downside is that formatting can ruin an SD card...but it's not much to worry about if the card isn't working, anyway =p

formatting can ruin an SD Card? please elaborate. i format SD cards all the time.
I've had a few where the format went "bad" due to some reason and rendered the SD card completely useless. Same has happened to a few people I know and have read of the issue before. I didn't mean that to say "Formatting your SD card enough will ruin it" lol.

I just unmounted mine in Android and formatted it with Windoze. Then I formatted it again in Android. I've corrupted SD Cards all kinds of ways. It's real easy to do if you get stupid with the overclocking/undervolting. I've formatted the 32 gig I first got for my BlackBerry 9630 a few dozen times. It's still as reliable as any other SD Card I have. Better than some, in fact. The only real good way to format a solid state memory device is to write zeros to it. If not, NAND (which your SD Card is) device write cycles can take twice as long.
guys i tried all the format methods listed above still no luck, windows states its a raw format with 0 mb available

I had to download a program that was made just for formatting SD cards. Once I used that it formatted the card fine but windows and my phone would not.

Apps installed on my Rezound can no longer "see" my external SD Card?

My Rezound just started doing this in the past two days. Stock storage under settings can not see my external SD Card. No apps installed on the phone can see it either. Root explorer is the same. Funny thing is that stock Recovery can see it. I can flash RUUs. I can boot to AmonRa and its file explorer can see it and things flash fine. Anyone ever had this problem? I have factory reset in recovery...reflashed last ota RUU.....still have the same problem. The SD card works fine in my wife's phone.

Does it give you the option to format it from within your rom? Or does it just say unavailable? Do you have another sd card to test?

Does it with any SD card I put in.....says unavailable and is grayed out?

Have you tried doing right after doing an ruu like stock unrooted?
And did you s off? That can corrupt external sd cards but that doesn't explain other sd cards that weren't used during the process.
I hate to jump to conclusions but it sounds like a hardware malfunction. Maybe time for a warranty replacement

I've been S-off for quite some time. I have gotten it to read the card a couple of times today. I was able to restore some apps with titanium. When I plugged the phone in to charge ...I saw a quick popup....." SD Card unexpectedly removed". When it starts and the External Card is in Settings the phone works normally. But when the SD Card disappears all of the Apps that draw from or write to the External SD Card behave Strangely. It is very near stock now. It is frustrating that it works very well when set up excluding the external SD Card. I do have alot of things on the SD Card that I use a lot.....Guess I'll call support
Can you pull your SD Card and plug it into a computer? Copy over everything to a folder then reformat Card and put in phone, then if works copy everything back over. If still doesn't work I would suggest flashing the stock image since it will basically reset everything. Good luck.
I would keep working with people on here, those kinds of issues and support usually equal face palm or headache.
For reason unknown...when I restarted this morning the ext_SD mounted fine this morning and has been working fine since 5am. We'll see if everything makes it thru the day...lol

If it happens again, go into storage and select mount sd card. If it is mounted already, unmount then mount. Happens to me occasionally.

Well finally just started over....Wiped and reflashed phone. Then copied and reformatted SD Card, copied back to card ......everything is fine so far. We'll see how it goes tomorrow.
similar problem
I am having a similar problem. I just installed Neo's RAGE 1.9 rom, inverted Gapps, and flashed the boot.img since I am S-ON. Now I can't get to my ext SD once the phone boots up. Similar to manbat above, I can browse it in AmonRa, and even flash from it there, but after booting up the phone I get the "damaged SD card" message, and I can't access it. I've re-flashed the rom 3 times, and also the boot.img...even re-downloaded the rom, inverted gapps and tried all over again - but nothing changed :/ If anyone can help me out on this it'd be greatly appreciated!
You will have to copy your SD Card to computer. Since your phone is reading the SD Card as damaged you will have to reformat on your card on the computer and then copy your information back to your card. This is what worked for me.

Need to FORMAT SD card

I already have apps on my SD card that I had moved over in the past but any other apps I move now become corrupted and useless. I'm hoping that formating the card will fix this issue. Can I just copy all contents from the card over to my pc then copy them back on after the format? Should everything work correctly? I have 6gigs of spotify music and other big data files. Hope someone answers Thanks!

I'm on lollipop with klte root. Man I messed up. I transfered all the contents from my sd over to my pc to format it and when I switched everything back over the folders came up as all empty. And I can't seem to recreate a folder called .android_secure. My storage info shows that about 9gigs of space are being used on the sd but the folders show nothing. 6gigs were of pure spotify offline music. This is not a good day. Tons of pics were there too.

I have done the same. In MM was concerned that my SD data would be gone. Made the transfer to the PC of everything. After seeing what MM did to my SD, I formatted the SD again and transferred from the PC to the SD and all was fine. If you want that info back and it is still on the PC, then just do the same. In my case after the format, all was as before.
I lost everything on the card. Dammit. I want to just do a complete hard reset of my phone. If I do a backup with kies will I be able to add all my apps and settings back on my phone afterwards with a recovery of the backup?

I recommend using Kies and Another Backup Solution as I've had problems with Kies backups in the past, causing me to lose saved texts, contacts, memos, settings, etc.
I personally recommend using Helium backup from ClockworkMod, a quick search through google play should get it for ya.
Happy resetting! :3
EDIT: Just realized this thread is old... you've probably already reset the phone. Sorry I didn't pay attention to the date stamp..
It's almost scary that you would have responded to this thread right now. I am going through the exact same mess again. I tried applying a fix to make the external card detectable by other apps which were not detecting it. Well after doing that none of my apps or data on the card show up or work. The files are there if I explore root folder though. How do I regain the pathway to the card? Through my USB on pc it does not show the external but it does if I use sd card reader with the sd card by itself. Last time I copied everything from the card to my pc then formatted. It all became a senseless mess when I tried returning everything to the card. Lost everything. I tried backing up with kies before but it did not give option to backup sd card. Please help is an understatement. I just checked the sd card for errors using Windows tools but no errors popped up.

The reason for this occurrence (as well as how to fix it) depend on how the fix was applied.
Please describe the nature of the fix as specifically as you can. Things like where you found it, what it does, how you installed it, as well as if this is the same SD card, will help the most.
Edit: if you could also include the file system that's on the card that would be great too.
Thank you for responding. I'm not sure what the file system on the card would be but I've attached a screenshot of what I did. The name of the app is there.

Well I found the app in question in the play store, and was unable to track down exactly what it does, so we can't get anything out of that.
To get the file system that's on the card all you have to do is put it in a Windows PC and look at the drive properties.
At this point the best thing to do would be to back up everything on the card to a computer.
