[Q] sd card damaged

last night, my i booted up my phone, and it said sd card damaged. i didnt pay that much attention to it then, bcuz i always take my external sd card out wen it is mounted as mnt/emmc (im using cm7, so it gives me this option), and then it doesnt read for a few days. this morning, i realized that it was my internal sd card (because i can access my external storage), and half my apps are gone, so i decided to format it. i pressed format, it deleted my data and then it gave me a notification saying sd card is now safe to remove. i rebooted my phone, now its stuck in a bootloop. i can get into cwm, but it says E:cant mount /cache/recovery/command
E:cant mount /cache/recovery/log
E:cant open /cache/recovery/log
E:cant mount /cache/recovery/last_log
E:cant open /cache/recovery/last_log
i tried using the g2x cleanup batch, then reflashed everything, but that took me back to sqaure one.
im guessing that im goin to be needing a new phone right? if so, what could i hav possibly done to get myself into this mess?

This is a good tool for recovery try it:

Good luck
You will need to root your phone again and reinstall CWM, in the future backup your SD card to PC every week. Make sure to replace your SD card with anew one

Nice
@maxesxp
What did you do to fix it? I've had the same problem now for a bit and I can flash a new rom or reflash stock and get back to a CM7 ROM but after a bit the internal SD card craps out and "Damaged SD Card" shows up again. What did you find to fix it?
Thanks

Thanks! I got it fixed by stalking you guys on a few other threads too. I had to reflash just one more time and then was able to flash a CM7 build, a new kernel and some other junk (LG cam, owain's v21y fix). That 9 to 8 partition swap was a great find. Thanks again for the help.

SD card corrupted?

I can't seem to boot my device anymore. I tried flashing the viperone s rom and when it was about to install the device shut down :/
Now TWRP says I don't have an OS installed, I can acces the SD via twrp file manager but it only has a twrp folder and none of my data stored there and I can't mount it as usb storage as windows tells me I need to format the drive first. It also keeps connecting and disconnecting usb on its own.
How do I proceed?
Uh...format the drive

I can't, Unable to mount '/sdcart' (tw_mount)
failed to mount /sdcard (Invalid argument)
When connecting via usb it keeps reconnecting so it pops up every second and then disappears.
The strange thing is that TWRP can save logs to the sd card and they show up in the file manager, but I can't wipe/install/do anything useful with it.

that's happened to me wiz my 8GB transecond memory buy a new one man it's corrupted memory & forget it's never mount again!
I managed to get the SD card working by reflashing the stock recovery. I also found out the usb cable was faulty.. Too bad I've lost all my data... That was stupid ><
And yet again has TWRP corrupted my sdcard. Not sure what is happening, but again when installing a new rom everything gets messed up

[Q] Error installing from SD card

EMMC is not the SD card , its internal system memory. Can you list the steps you are taking exactly.
Have you done a system reset or clear data from stock ICS or stock recovery? IF so you may have encountered the EMMC bug
Well I can install from SD again, but now when I try to flash the stock ROM it succeeds but it boot-loops, could that be the EMMC bug?

Can't install .zip file from CWM

I am relatively new to the world of rooting and ROMs, but I have successfully installed CM10 on a previous Samsung phone, so I am decently literate.
I am currently attempting to install CM10.1 on my Verizon Galaxy S III (following the instructions on the Install CM for d2vzw page on the CM wiki), but I have reached an impasse at step 7. I was not aware that I had to put the VRALE6.bootloader.zip file on the SD card before starting this process, so I am now attempting to get that file onto my SD card either by sideloading through CWM or by pushing it to the SD card through adb. The issue is that CWM gives me an error (can't mount SD card) and adb doesn't recognize my device (I have tried installing and reinstalling various drivers for the past few hours). I enabled USB Debugging mode before starting the process, but I am only able to get into Download and CWM modes right now (if I don't do the Download Mode or Recovery Mode key combination, I am stuck on the Galaxy S III screen). Am I bricked at this point, or is there a way to get VRALE6.bootloader.zip onto my phone and continue with the ROM process?
It is important to note that I formatted the SD card before starting this process because I wanted enough space to put the Cyanogenmod file on it. However, I think I may have formatted it generically rather than into FAT-32. Could this be the issue?
I am going to pick up a microSD card reader today in order to flash the SD card to FAT-32 and put the CyanogenMod file on it.
I am getting 5 errors upon startup of CWM (E: Can't mount /cache/recovery/command, can't mount /cache/recovery/log, etc.). When I try to mount the SD card or external SD card, I get E: Can't mount /sdcard/
Same issue with sd card not mounting.
I'm having somewhat of the same issue. I've tried both Clockwork recovery and TWRP and have the same issue.
Should have mentioned that i still have access to the stock rom and can use my phone just fine.
I some how got Clockwork mod recovery to work using the Rom Manager pro App.
I wish i had been paying better attention to what i was doing but i know i updated CWMrecovery from in rom manager and chose to install my chosen rom with that.
My suggestion is to start over completely. There is a much easier way to do this.
My suggestion is to flash one of the rooted stock ROMs through Odin. There's a thread in android development that has rooted stock. Then when that's done boot up your phone. If it bootloops wipe data. Then use Ez-Unlock 1.2 app to unlock your bootloader. Make sure it's 1.2. Now use GooManager to flash TWRP. You are done! This is probably the easiest way to do this.

I am not familiar with TWRP, so is the process the same for flashing CM (putting CM zip file on sd card and going to install from SD card in TWRP)? Are there any additional steps beyond this?
I am following the directions in the thread linked above to root and install TWRP. So far, I have the rooted stock ROM running fine, but I can't get TWRP to work. I downloaded Goomanager and attempted to get TWRP using the Install Openrecovery Script option. However, it said that it couldn't find a recovery for my device. I also tried to use the adb method, but nothing happened after I put in the commands. I even tried to flash the latest TWRP .tar file from their website using Odin, but it keeps failing. Is there any way to get TWRP on my phone?
EDIT:Whoops, I skipped over the EZ-Unlock step. Now everything works. Thanks for the help, Sandman!

Alright, maybe I'm not quite fixed up yet. I have TWRP installed and I can go between TWRP, download mode, and the normal stock rooted ROM fine. However, I cannot get to the SD Card in TWRP in order to install CM. TWRP gives me the following errors upon booting into recovery:
E: Unable to find parition size for '/boot'
E: Unable to find parition size for '/data'
E: Unable to find parition size for '/recovery'
Updating partition details:
E: Unable to mount '/system'
E: Unable to mount '/cache'
E: Unable to mount '/cache'
E: TWFunc: :Copy_Log - - Can't open destination log
E: Unable to mount '/cache'
Upon trying to go to Install, I am unable to select the external SD card, and an additional error appears when I attempt to touch Micro SD Card (E: Unable to mount '/external_sd').
I guess I could try to sideload the CM zip file through adb, but I would rather fix the SD card for future use. I have been researching and working on the SD card for the better part of today, to no avail. I am pretty sure the issue is in the formatting of the SD card (it appears to be RAW rather than the required FAT32 for CM), but I cannot format the SD card into FAT-32 no matter what I try (both Windows and 3rd party formatting tools). They all say that the SD card is either write-protected (I have already checked the read/write switch on the side of the SD card adapter) and/or the format cannot be completed. I have tried both my old SD card that I have kept for a few phones (an 8GB Samsung microSD card) and a brand new Sandisk 8GB microSD card, both of which will not work.
I am able to transfer files to the SD card with no issue (with both ADB and through dragging/dropping in Windows), but I cannot install from SD in recovery.
Does anyone have a solution to allow me to install CM on my phone?

Yes, I do have root access. I think the problem lies somewhere in my SD card.

Do you have another computer to try formatting the sdcard with? And you said that you receive the same errors when trying to reformat the new 8 GB sdcard as with your other sdcard which is formatted to RAW?

I do have access to another computer, but I ran out of time and patience yesterday. I will try it when I get home later today. And yes, both cards are RAW (even the new one) and I can't get either one to format or work in TWRP.
So it appears the the issue with formatting was due to my computer's drivers (even though I installed the latest Samsung USB drivers) and not the SD card. I was able to format the SD card to FAT32 on another computer and put CM and GAPPS onto it. When booted normally into TouchWiz, the phone sees the SD card fine. However, I still get the same "Can't mount external SD card" error as well as the others previously listed when I attempt to install a zip from recovery. I even tried to sideload the ROM from ADB, but it still didn't work.

Which version of CWM and also TWRP are you using?
And the problems keep rolling in. I was able to mount my SD card and get rid of the TWRP errors by installing a modded TWRP 2.6.0.0 from this thread (http://forum.xda-developers.com/showthread.php?p=44277901). However, when I go to install CM (cm-10.1.3-d2vzw.zip), I get the following error:
assert failed: getprop("ro.product.device") ==
E: Error executing updater binary in zip '/external_sd/cm-10.1.3-d2vzw.zip'
Error flashing zip '/external_sd/cm-10.1.3-d2vzw.zip'
Updating partition details
I did a factory reset before attempting to install this, but I did not format data or do anything else.

Well, that is for the Sprint S3 my friend. We can't interchange recoveries between the different S3 models to flash roms. You may want to ask Kennyglass123 or any of those other guys if they can make a change for the VZW S3 for you to test it out.

Sounds good. I think the problem has been isolated to being something with needing a modded TWRP. I tried using an older, non-modded TWRP (2.5.0.0), which didn't work.

Would you mind trying this soft brick fix? If I'm not mistaken, I believe you're experiencing this same issue--excluding the Sprint TWRP issue you just mentioned. You will need to flash your VZW custom recovery either through GooManager, Rom Manager, or Odin btw.

I can still get between the stock rooted ROM, download mode, and recovery mode fine, so does that mean I am still soft-bricked and should try this?

This soft brick fix is an attempt to correct the /system and /data errors.
