SD card not detected? - Verizon Samsung Galaxy S 4

I have a PNY 32gb sdcard that's been working perfectly since I picked up the S4 in May. This morning there was a message on my phone saying there isn't an sdcard detected. I've tried popping it in and out several times, rebooting, etc. None of that helped. It's not even visible in recovery. Does anyone have any suggestions? I'm stumped.

Sometimes sd cards go bad without warning. It's best to keep your important things backed up on your computer. Sounds to me like you need a new card.

Yeah, I guess the obvious next troubleshooting step here is trying a different sdcard (which I don't have now). Just wanted to see if there was a known issue slash easy solution that was out there already.

You can try your sd card in your computer before trashing it. You might be able to get it to work long enough to retrieve your saved files.

SD CARD

Just recently I noticed that I can not save anything new to my SD card. I can delete something off the card only for it to reappear. Wiped everything reinstalled backups doesn't seem to matter. Any suggestions.

I hate to day it but sounds like you need to reformat the SD card.

I was thinking the same thing. I had been using bootmanager as you know runs different ROMS directly off the card. I can't say if that was the cause but everything is leading that way. For instance, everytime I may need to reboot the phone it automatically boots in bootmanager... long story.

I've heard people having lots of issues with bootmanager. It may be part of your problem as well.

[Help] Thunderbolt SD Card

Hey guys.
So I went to work today and while I was on break, my phone acted up a couple of times. Once, the mobile internet cut itself off and I had to restart my phone to get it to turn back on.
Then when I get off of work, my phone isn't reading my SD card.
I tried unmounting and then mounting it back several times, but no luck getting anything.
So then I hooked it into a card reader on my computer and all the files show up, then suddenly the computer got an error saying that the driver wasn't recognized and then stopped reading it.
What is the problem and how can this be fixed?
I can even open Root Browser app and it shows all the files on my SD card. All pictures, music, videos, etc.
But for some reason when I go to gallery, music, or whatever else... it won't pull up.
Back it up to pc if u can then reformat it to fat32

I wish I could. My computer will read it but only for a few seconds and then says something about a driver error.
I'm guessing the card may be going bad?
Can u mount phone to pc?

Just tried doing this, and surprisingly, yes. So I got it all copying to the computer now.
It just doesn't make sense to me that it can mount like this and my files still be on the card and not read when I go to pull them up. Especially when I go to Root Browser and I can see all the files.

So I copied all files to my computer, formatted the SD card again, put all files back onto the SD, and still have the same problem.
Note that my phone is reading the SD in Root Browser; however, when I go to my gallery, music, videos, etc.. my phone tells me that there are none and acts as if the SD card is empty. I even go to SD and Storage and it says my card is empty, but it's not.

You're going to need a new one bud. There is definitely something wrong with it physically if you have done aall of that and it is still doing that.

Just wiped my phone completely and restored my most recent backup and now my phone reads it just fine, so problem fixed.
Undoubtedly my phone got set to some strange setting while it was in my back pocket that I never knew my phone had.
Strange. =\
Thanks for the help guys. I suppose if you see anyone or if you run into this problem in the future, here's how it can be fixed.

You didn't use quick format, did you? If so, try formatting it without quick format.

I had the same problem, I did the same thing as well. I noticed it happen when I downloaded a free game app from Amazon App store. I had to uninstall it b/c it kept on force closing. Soon after I had this SD problem.

The thing is... I haven't downloaded or changed anything at all with my phone in over 2 weeks. Either it tripped out or something happened to where a setting changed while it was in my back pocket.
Glad I fixed it.
I had a feeling it was probably a setting issue that happened, so I got the idea to restore from a backup to get back original settings and BAM!

[Q] At&t SGS2 cannot read my MicroSD

Here's the deal:
My at&t SGS2 cannot read my microsd (transcend 16gb)....and i haven't backed up (I was too lazy...)
This morning i noticed a strange notification regarding my microsd....something about it being UNMOUNTED......but since i was sleepy, i ignored it
Over the course of the day, i noticed less no. of songs and pictures being displayed, so i remembered this morning's msg and when i opened my battery case, i noticed it had bulged out, so i inserted it back in and then restarted but alas!, my phone could'nt read it......tried restarting 3-4 times each time removing the sd and inserting again, but from then onwards my phone hasnt been able to read my microsd......
I connected my phone to the pc via usb mass storage, but it showed only 1 drive(instead of the usual 2 drives...[1 belonging to the microsd of course]).....the thing is that even the pc doesnt read it.......SO MY QUESTION ARISES HERE:::Can i somehow get back my precious data???...it doesnt matter whether i can use my microsd or not....i just want back my DATA......Please Help if you can!!!! A lot of thanks!!!!!!!!!
You will want to plug the sd card into your pc. You might need to get an adapter. If your data shows up, make a backup right away. If it doesn't, try any number of undelete programs. Piriform makes one I like to use.
Your SD card could be shot and there may be no way to get any of the data.

Insert sd into computer. Run program. Select drive letter of sd card. Hit go, start, or whatever the button is.
If you need more help than that read the help menu on the program.

If your computer can't read the card, it is most likely toast.

Sdcard empty????

This just started happening to me this evening. I randomly get this message. .. Sdcard empty, unmounted, or not present. Never experienced an error like this in the past. I'm running Beans 7, sdswap, perseus kernel with 5g profile. Does anyone have a clue to this problem?

What class of sdcard do you have? Sdcard specs, please. Bet it's crap. Lol. Seriously. Not being a jerk. Troubleshooting.

Did you get it from Amazon? If so it probably is a bad card. I've seen quit a few people who got a bad batch from ordering on Amazon. Try what Wolf said, backup and format

Tried that. Several times. Been having similar problems with my sd card. Its a samsung 64gb class ten. I cant find any of my downloads. I am a noob but I think the sd swap does something to the card. Only causes a problem if you flash a new rom (or reflash same) that doesn't have swap.

Aren't you supposed to delete a few files when returning from a swap? Though I read that.

Well... After reformatting my scdard and also performing a fresh and clean install of my beans 7 rom, I'm still having the same problem once again.... I reformatted to extfat. Should I have went with fat?

I slow reformatted mine and the error came up again after a few hours. Decided to just buy a new one so hopefully the card was just crapping out and not the phone. If end up posting again it must be the phone. Hope you don't hear from me again in this thread lol
Im having the same exact issue as you. Its very annoying

Sandisk 64GB SDXC which happens to be Made in China is crap and confirmed by comments made by others on Amazon saying the same. Pay a little extra for Samsung 64GB SDXC and have the peace of mind.
Same issue for me and I bought my sdcard from Best Buy also...I am running Jelly Bean ROM B7. The card is only 2 months old so I doubt the card went bad, this has to be some app/process that is effecting the sdcard swap program. Very annoying and reboot of phone resolves issue but I have to reboot every hr, it is unreasonable. It only started happening to me since B7 which i installed about 7 days ago. I may trying going back to B6 which i was using with no issues for a while.
I'm just waiting for my Sandisk 64gb ultra cl10 to die bought it about 3 weeks ago so will see glad it has a 10year/lifetime warranty. Plenty of people are having same problems with these cards and not just in phones. Easy way to tell if its bad/going bad is to format it and stick it in another device see whats up... pretty sure if your card is not mounting or being seen it's going bad if it pops back up from time to time it's about to be dead.
Well I finally returned the sdcard at Best Buy which honors manufacturer warranties. Been a week on the new card, so far so good...

BU & replace sd card

I want to replace my current sd card with a larger card but I don't know how to elegantly (& smoothly) lay down everything that was on the old card into the new card. I tried transferring via my computer but that didn't work. I'm sure members have done this, can you please share your 1,2,3...experience?

I backed up my 64gb card and transferred everything to my newer 128gb card, it went fine just took a while.
You can use the old one in another device and use Wi-Fi direct or super beam to do the transfer
Sent from my SM-N900P using Tapatalk
Thanks for your input. The phone got so screwed that i will have to back up my data to drop box, and unroot my phone, re-install the factory software, re- format the 128gb card, and reinstall all my stuff. And I still don't know why the phone went haywire so badly. There simply was no good reason. Except maybe the weather was contrary.
