SD card mounted Read Only - Thunderbolt General

Hey guys, just picked up my thunderbolt and I am loving it. But I was moving some files to my SD card this morning and when i unplugged the phone from my computer, I got SD Card mounted read only. Is there any way to fix this? I did some searches and saw you can boot to recovery and wipe/format the SD card but how do you boot to recovery on the Thunderbolt?
Thanks!

Put it in a computer and see what it says. Are you rooted? If so volume down and power at the same time. I'm assuming your not rooted cuz you don't know what recovery is.

Did you try cycling power?
It's amazing what a power down and restart fixes.

turns out it needed to be reformatted. simple fix thanks!

Upgrade to Cyanogen 4.2.12.2 results in blank screen

Yesterday I upgraded to 4.2.12.2. After rebooting I see the Tmoble screen then the android screen then nothing.
After doing some reading last night I pulled the SD card and rebooted. The phone now boots properly. If I then insert the SD card I can access images and audio files but my apps are still gone.
Did something change with Apps2SD? Does anyone have suggestions on how to recover?
Thanks

wrong section..but use a sdcard reader put your files on the computer..let your phoone boot up without the card..then reformat for sdcard(fat32 ext2 swap etc.)..then put the files back on the sd..see if that works..*not an expert just something i would try*

Formatting SD Error

OKay guys I formatted my SD card on my MT3G 32B and now the SD is Blank but my phone wont recognize it. I only Get a Blank SD card. Also I tried accessing the Power Off + Home so I can format it from there and It wont display the menu. I've tried it aswell without the SD card inside the phone and it's a no go. My phone still works but it's slow since I am running HERO.
Anything you guys can tell me to fix this? I am using AMON-Ra's and Kingxxx whatever hero rom long ass name...
Nevermind... I swear technology has it's own mind and everything... I managed to fix it the phone Formatted it. But now I the SD is not readable by my Mac :S weird...
PS. It fixed itself lol

SDCard not showing up in recovery.

followed the guide to install GB, and when it gets to the point of ut rom on sdcard, flash rom in clockwork: clockwork now says there is no sd, or that it count mount it. the phone can read my sd, inside the os once booted, as can my computer and anything else i plug it into, even my head unit in my car. any ideas?
Format the card on the phone. Then create the partition on the phone in cwm. Shut down completely. Take out the sd card and transfer the files from the computer using a reader. Then try again.

The sd-ext in CWM actually isn't what you're thinking it is. In CWM, SD-EXT is referring to one specific folder on the external SD card, not the whole card, and if that file isn't there, it throws up that error.
If you can see your external card by putting it in an adapter and hooking it up to your computer, I'd suggest moving everything off the card and onto your computer, formatting the card (FAT32, I believe), and then putting it back into your phone.
See if that helps.
Hey man.
It did not work!
The ext-sd didn't apears, even, at the configuration menu.
When i connect the celphone to the computers, appears only theo original sd.
I'tryed a friends sd, but it don't read to.
I thinking that is a hardware issue.
What could i do?

I'm not sure how drastic you want to get, but if it's not reading any external microSD cards, you could back up everything on your phone, then flash back to stock and do a master clear. That might set right whatever is messing up. If that doesn't fix it, you might have a hardware issue on your hands.
Thanks for the help!
I'll try this as soon as i can, and post the results in here!

I think I have the same issue. Sometimes it randomly pops up saying "blank SD card" or "damaged SD card" message. And I have to reboot to get the card to work again. And it may fail randomly later. :/

What size/class sd cards are you guys trying to use?
8 GB class 4 San disk
-Sent from a Galaxy far far away
Kingston 16 gb class 4
My external_sd isn't working, neither randomly...

Do you have an adapter for the MicroSD that you could use to put it into your computer (outside of the phone) to test and make sure it's good?
I experienced the same erratic behavior with a new 16gig class 4 SanDisk. But, my 8gig class 4 SanDisk works perfectly. I'm running MIUI,btw. When I flash back to stock kf1, they both work perfectly.

Question about Boot Manager

OK, so people talk about boot manager a lot, and something just came to mind... what would happen to the phone it you were booted into an SD card ROM, and the card was unmounted by accident? This could be a problem!
Sent from my Sensation using XDA
my guess is the phone will probably freeze or reboot, possible into recovery, if the sd was taken out. i dont think it would continue from the cache. if that happens you would need to go into recovery and apply the Rom Manager created update.zip found at /sdcard/BootManager/phoneRom once that finishes the phone will boot into the rom it has installed on the phone itself. i see using Rom Manager as a way to test potential roms anyway not to continue using from the card. especially if the card is class 4 or below. anyway, just dont remove the card and no worries
Thanks, that makes sense! But my issue is that infrequently, but it does happen, the memory card will RANDOMLY unmount... and then I have to remove it and plug it back in...

I also have issued with my new 32gb class 6, what I find is there will be corrupt file on SD card just few but make the phone always unmount. To solve the issues I have try format with various software and method. Even try using SDFormat tool but it will have same problem. After a lot of try I think I have a solution.
Format the microsd card on Storage Setting [ Settings > Storage > SD card > Unmount > Format ]. I also find the micro sd card can't be defrag or alter with computer.
I usually defrag with Defraggler, and it's always unmount. I think the phone can't really handle sdcard with class 6 and above because don't have issued with my other's class 4 card.
The Stock ROM I find always have issued than Custom ROM
Please backup or copy your file first to computer or other storage then copy back.
Just my 2 cent, do at your own risk.
