SD Card Randomly umounting itself

Hello All,
I replaced the SD card in my DI (Stock 2.1-update1), with an older 8GB I had laying around. Now every once in a while the phone says the card was removed without warning. Powercycling the phone won't bring it back, however a battery pull will, as will ejecting and re-inserting with the phone on.
This leads me to believe it's not a contact issue (as the battery pull fixes it)
I want to see if anyone else has similar problems, and try and see if it's just a ****ty SD card (I don't have another to try long term, but I can just grab a 8/16GB from amazon if I have to) or if it's related to bad hardware in my phone, or some software issue.
Thanks in advance,
Spencer

I haven't noticed random unmounting of the SD card, however I've noticed that when I plug my phone into a usb port of a Windows 7 machine it will mount the SD card.
Some apps will notify me that my SD card is mounted and I have to manually set my phones usb mode to disk drive and back to charge only in order to unmount the SD card.
This happens on the leaked 2.2 with the 2gb SD card that came with my phone.
Maybe both instances are bugs?

Is your SD card formatted to fat32?

My card is formatted in FAT32, with the 2.2 leak, and it unmounts the SD card whenever I plug it into the stock charger in the wall. Would reformatting it to something else stop that?

My card is formatted with whatever the phone formats cards as. Mine seems to stick to USB only when it's plugged in, maybe just a bug of the leak for it defaulting to something else.
Do you have Sync installed?

In my experience, I was running the 2.2 leak with hydra kernel and it was giving me an SD mounting error constantly. Never did I have a problem with stock. Thats why I just went back to it actually.

[Q] Can not mount SD card

Hello!
I really need help.
I have stock EG22 rom and 32gb SD card. Everything was ok but suddenly I can't mount SD card. If I'm loading into Nandroid everything from SD card available. But if I'm booting the system nothing available and "MyFiles" app says your SD card not inserted.
Few times tried to change the Rom and cleaned data. Nothing helps.
Phone is rooted
Please, I need help, advice, etc? Help me, please?

Suggestions
For me, anytime I have an issue with my SD card, I take it out and clean the connections. Retry.
If still no dice, I backup everything to my PC and format the card. Then I move back critical folders/files, insert the card and try again. (This usually is the fix.)
If still no luck, then if you still have the SD card that came with the phone, try that one.
Could always try reflashing the rom again without wiping data.
Did you have this problem on Froyo?

Didn't have this problem on Froyo and I think I'll try to odin EC05 rom.
Thanks

I have the same problem on the SUPERNOVA ROM,Weird! My friends don't have this problem on their epics with supernova. is it a bad download??

It could be a sign that the SD card needs reformatting. This has fixed issues for many. Doesn't hurt to try. Backup all data on sd card to a computer then reformat sd card in the phone...this is important for best compatibility. Then restore your data.

Most likely a rom issue but I do have to say that the EPIC 4G can and will kill and SD card. They have problems getting hot, especially if you use the LED flashlight app and leave it on for awhile, the metal harness around the microSD gets really hot and bricks the sd card. My epic 4g ruined my 8GB card as well as another 4GB card due to this. My 4GB card will not mount, will not format, not even in a computer so It is toast I assume and my 8GB card just doesnt get found.

It also seems to be very finicky with the 32 MB cards. So def reformat. Also Gingerbread leaks seem to access it slightly differently than Froyo ROMs. So problems show up in GB that don't in froyo.

You were right. I've reformatted the card and right now it is working. Actually, it didn't matter it was a Froyo Or Gingerbread.
After reformatting everything works just fine.
And I did reformatted it on my computer, because my phone was not doing it.
Thank you very much!

sd card keeps unexpectedly unmounting

my phone dropped a few weeks ago with my case on about 3ft off the table. the case didn't come off but my sd card got unmounted. it didn't bother me, just took the sd card out and placed it back in and worked fine. but now, every other day it keeps unmounting itself. formatted the card a few times already, fat32. card still read with the sd card adapter. is it the card or the memory card reader in the phone itself? its a 16gb class 10 wintec card
also read that the memory card can get shocked while it's in the phone? anyone knows if thats true

I had this issue except when it unmounted the SD card could not be mounted. I accidentally formatted the system. I realized the error if my way and it was too late. Thankfully I had a SD card reader and was able to format my SD card and flash a new rom. I think this was caused from going back to GB and ICS somehow the data in SD card got currupted. For me formatting solved my problem( I think so far no issue) you said you tried that, maybe your card is going out try a new card for a couple of weeks and see if that fixes anything

SD card removes it self (virtuous Infinity Alpha 3)

I am running Infinity alpha 3 and everything is running supper except that I keep getting the "SD card unexpectedly removed" message and can't do anything to fix it except reboot but then I get it again after a few minutes. The card is class 10 16gb freshly formated.
Any help is appreciated

The strange thing is that with another 16gb card the problems persist but when I put in the stock 8gb card that came whit the phone everything is working fine. All the ad cards are working fine whit other roms.
That's just feedback for everyone and team virtuous.

try reformatting the cards that aren't working, in FAT32 format. Don't choose quick format!
Let me know if that works for you.

Already did that with both the non working cards.
And also tried different cluster sizes.

Could you try this:
-try to format your card on a different pc. It is preferable to use a card reader.
Some ppl were having the same issue.
It turned out that to some of them the sd was damaged (it needed to be replaced), others tried to format the card using another card reader (full format) and it worked.
Also, if you could, try a different sd card (new one if possible) other than the one it came with. does it work?

"SD card unexpectedly removed" thats what i get on all ICS roms,it cant be cards error as it works fine on Ginger roms,tried format tried all things that i know

When you say all ICS ROMs does it include the stock ROM as well? Have you tried different SD Cards?
Have you tried your card on a different ICS phone?

I have tried other ics roms (sense 4.0а, AOSP) but never had this problem before.
Also all the cards works in recovery.

If your computer's OS is Windows, I suggest you use FAT32 because your computer can read it.
On the other hand, ext2/4 can not be read on windows without a special extbrowser.
Now even though the FAT32 wastes some space in your SD, it hasn't been a problem for many ppl.

Same error - on Sense-based ROMs only
I have the EXACT same issue of the SD card unmounting itself randomly. I tried 2 different SD cards (8 GB, 32 GB) BUT the problem ONLY happens with Sense-based ICS ROMs. Already did a CHKDSK via windows and found no errors.
MIUI 2.8.x works perfectly, no errors whatsoever over 1 week period. But on ROMs like BlackOut, Mabsa and Nik Project X, I get it every hour or so and have to do a restart. All other features of those ROMs work great otherwise, even the USB storage mounting via the PC works fine (until the error pops up).
Would appreciate any help!

Hi

MicroSD "Blank" - Galaxy Note 3
I am having the same issue, phone refuses to see my SD card. Has anyone figured out a work around for this, or is it most likely a hardware issue? Galaxy Note 3 (SM-N900V), non rooted.
Have tried multiple microSD's (SanDisk 32GB HC C4, Sandisk 32GB HC U1) that both read correctly on PC. Have tried reformatting with through Windows --> my computer --> format and with SDA SD formatter software (full format, not quick). Phone still will not recognize it.
Also tried connecting phone via USB with SD card inserted, it doesn't show up anywhere in the directory to try formatting it there (image attached). I do get the option to format what I am assuming is the entire phone, this seems like a poor decision.
I have dug around the forum, the majority of the fix's point towards reformatting via PC, does not seem to solve the issue for me. Any advice very much appreciated!! Really hoping it isn't going to require a new phone.
Thanks!

You could do a factory reset and see if that helps. If not, you might have a bad SD card slot.

Bad SD card slot
Yep it was a bad SD card slot. Had Amazon send a replacement, read the card right away.

The problem was the phone it was a brand new phone I went to Verizon in they replace it with a new at the store
