Won't boot with SD card fitted

Hi,
(running MCR3.1)
I installed a 16Gb card last night, and everything seemed ok until I got to work today and it appeard Apps to Sd wasn't working.
I used Rom manager to partition the SD card, but the phone will no longer boot with the SD card fitted.
When I remove the SD card the phone works fine.
Anyone got any suggestions, apart from wait till I get home and reformat the card on my PC.
edit....ok, fixed it. took ages, but now working.

CWM Not detecting ONE of my SDHC cards (the other one works fine, wtf?)

I have a strange issue with CWM.
With my 4GB Micro SDHC card (formatted Fat32), CWM detects .zip files perfectly fine.
However, when I format my other Micro SDHC card (the 16GB one that came with my Nitro HD) and then copy the contents of the 4GB SDHC card to it, CWM does not detect any .zip files. The card works fine in Android, and I can see the .zip update files in FS File Explorer. But CWM is totally borked when I try to use this 16GB card, even though the card works fine otherwise. The 16GB card is also formatted in FAT32.
Any ideas? I've tried formatting the 16GB card within CWM, but it won't even format. CWM will say the format is done, but when I insert the card into my computer all the files are still there.

Download the official SD card formatter here: https://www.sdcard.org/downloads/formatter_3/ . Connect the SD card to your computer directly using a card reader, and use this program to format the card. It will do a deeper level format than what happens when you format the card with Windows. After that, the card should work fine in CWM.
This is a known issue with the SD cards that come with the Nitro. It's formatted in some weird way that causes issues, and one way to fix it is to use this application.

[Q] Galaxy S3 and Computer don't see sd card

So i have a sandisk 32gb micro sd card im using in my galaxy s3. It has been working fine until this morning when my phone started saying sd card had been removed please enter a new one, or something like that. The sd card cannot be seen in TWRP or in any file manager. In recovery i tried to wipe the external card and it just says it cant mount the external card.
I would have thought this was a problem with my phone, but I also cannot see the card when i put it in my computer. Other sd cards work fine on my computer (i dont have another micro sd to test with) but my camera's sd card worked fine. Anyone have a solution? I would be willing to format my sd card, but i cant even access it anywhere.

I hate to say it, but it would seem that your SD card went tango uniform. If another card is being seen in the S III then it is down to that.

In Win7, plug your SDcard into the card reader.
Type diskmgmt.msc into search or run.
Do you see your messed up SDcard in there?
If yes, you can format it, name it etc.
If that fails, find an app online called Gparted. (needs to burn to a CD)
This app works at boot and has fixed my most stubborn drive issues.

[Q] Ext Sd card not found

Hi,
I'm currently using Task's AOKP Rom and after performing a TWRP nandroid backup to my external sd card.. My external sd card started having problems. When I rebooted back to AOKP it showed an sd card error in the notifications asking me to reformat.
I've used this 32gb sd card for 4 months, installing various AOSP and TW JB roms with no problems at all. Yes, I wipe and flash everything correctly. This seemed to just happen randomly. I plugged my phone into my computer and it only shows my internal sd card available. When I go to mnt/extsdcard in file explorer, it shows no files.
Does anyone know a way to get my ext sd card working again? I'd like to get access to my files.
Thanks,
Tom

Update: it must just be my ext sd card... I plugged it into an adapter and it's not reading on my computer. My 8 gb version works fine but my 32 doesn't read at all. Any suggestions or is my sd card fried?

SD card problems stemming from CM10?

Ok. Here is the scenario. Was on stock rooted LCJ. SD card working perfectly there. I flash to MIUI after doing a totally clean wipe and I'm able to access the SD card via the rom and PC when I sync. I go into recovery and do a full wipe and then flash CM10 with gapps. CM10 loads up okay but i notice that i have a notification that the SD card is broken and I should try formatting it. I attempt to sync the phone to the pc via USB cable but only the internal storage will mount.
I go into recovery and confirm that TWRP can still see the contents of the SD card. Having confirmed that TWRP can see the SD card I do another full wipe and then restore my stock rooted LJC. However, after restoring LJC the SD card issue persist. The phone does an error check but it doesn't fix the issue. It recommends that I format the SD card which I don't want to do and don't know if it will work. I attempt to sync the phone to the PC with the USB cable (which has always worked) but only internal will mount. Go into recovery and the SD card's contents are still showing up.
Also, I have a Kingston Media reader which I pop the SD card into and connect to the PC. Even using this media reader the SD card is still not being seen and the PC says the card should be formatted. Basically the only damn thing that recognizes stuff on the SD card is TWRP.
Anyone have any good advice on this topic? BTW...I have a class 10 64GB sd card. As mentioned above I never ever had a problem with this thing. Have always mounted it to the PC w/o a problem and has always appeared on every rom I have ever tried until trying CM10 today.

41 views and not one person has any input? guess i'm going to have to format the card and hope that works. really sucks balls. wish i at least knew for sure what caused this problem.

had the exact same issue. I had just purchased a sandisk 64 gig the week before and when it happened I had a hard time believing it was the card that went bad. I had no luck recovering anything off of the card but did format it and it has worked fine since.

its not the card...............its the formatting of the card. it has to be formatted fat32 for it to be recognized in cm10. stock format is exFAT

I had the same issue with my SanDisk 64 GB drive. I went back to Synergy and the card is recognized in that ROM. I can't get CWM or TWRP to recognize the card though. I get an error whenever I try to access the card from recovery. It sucks that I have to put anything I want to flash on internal memory
