[Q] SD Card will not mount in Nexus S

Attempting to partition sd card with ext4 -a process I completed multiple times successfully on a Nexus One, the process appeared to complete but now the phone will not mount the sd card. I've tried a wipe/reset, to no avail. I can still access and partition the sd card through adb, but the phone cannot mount it to format/partition, restore from recovery, partition sd-card from within ClockWork Recovery, nothing. I've re-partitioned the sd card through adb, which indicated a successful completion, but the phone still refuses to mount the sd card. If this weren't a Nexus S with it's cursed internal sd-card I would simply swap out the sd card with another or format it externally like all the google topics I pull up on the subject suggest.
Is this fixable or has the fused sd-card scenario become a liability?
Common Error messages:

Can't mount /sdcard/.android_secure
Phone: Nexus S
Recovery Img: ClockworkMod Recovery 3.0.2.4
Rom: CM 7.0.3 (now wiped, cannot put back on since sd card won't mount)

/dev/block/platform/s3c-sdhci.0/by-name/media /sdcard vfat rw
Can mount everything except the last one, /sdcard.
I've attempted all: wipe/reset, format using clockwork, partition using clockwork, partition using adb, changing fstab, etc etc.
All topics I've found on the net end up being resolved by taking out the sd-card and formatting externally or using different card. i've had a N1 for well over a year and done far worse without problems, this phone seems to be very fragile for a 'developer' phone.

Are you able to go with ADB through the directories?
and yeah, false Section! Q&A would be better

I am having the same issue. I actually just got my phone back from Samsung support (which is real ****ty) because the SD card started having I/O issues.
According to the ticket information they replaced the PCB.
Anyway, I immediately installed Clockwork recovery and transferred the latest Blandroid rom to the root of the SD card. No matter what I do I cannot mount the SD card from the recovery menu or format it from the recovery menu. Mounting USB storage works fine, though.

Hiya I got the same problem
Any salutation yet ?

Yeah. Don't format the internal storage with clockworkmod etc.

I have that issue I cant even open phone now

1.power off...on it back...test it
2.plug your usb cable, boot into recovery..will heard usb sound from your PC, if does not work, try several times plug the usb untill you get usb sound...unplug, then reboot...
3.fresh install ROM...

Yeah, don't mess with the internal memory. I semi-bricked a Droid Incredible one time doing that. It ended up making all the internal partitions FAT. Took me hours to fix it. Be careful. I am afraid to even do it on my crespo4g. When I mount it in gparted running Linux Mint, the internal sd card showed up as not partitioned. I didn't even think about trying to partition it thinking back on the Incredible.

A solution, at least, for flashing/updating roms
Just happened to me, using CM9 after enabling the encryption I can't access the /data /sdcard paths. It would be nice to be able to read them but for me the biggest problem was how to update to the latest CM9 nighty.
In the end I've tricked the clockwork recovery to think the cache partition is the sdcard. I'll post the method in case someone find it useful.
1. Tranfer the update to the cache partition.
- Normally big enough, wipe it from the cwm if there is not enough space
adb push update-cm-9-20120305-NIGHTLY-crespo-signed.zip /cache/update.zip
2. Log into the phone and mount cache to sdcard.
adb shell
mount /dev/block/mtdblock4 /sdcard
3. Go into the cwm option to flash the uploaded package, it wont give you the mount error as we already mounted /sdcard
4. After the update log again and clear the update package, and unmount /sdcard
adb shell
rm /cache/update.zip
umount /sdcard
As long as you don't have to wipe you can continue updating and using your encrypted storage without much trouble

Help, internal storage not showing
Hi,
I wanted to go back from CM9 to Stock rom, but now I did something wrong (don't know what exactly) and my device is still on CM, but unable to access the internal storage. I cannot even take pictures or access it through CWM.
Any thoughts?

I have had no luck using multiple methods to partition sd card with Nexus S. Each time I can view the modified fat32 partition from windows, add files etc, but cannot be recognised from within CWM recovery.
Left me unable to reflash roms etc.
The only thing which has worked for me is to use mini tool for windows and mount usb storage from recovery. Do a refresh from mini tool and it should come up in the list of drives. delete the partition(s) you find there (not your notebook ones of course), and reformat it as fat 32.
CWM>Advanced>Reboot recovery, move over your rom to the sd card, then try to find it in CWM, should now show up :fingers-crossed:

Reformat your sd card especially if it is partitioned

I did that many times. Even did it with another android phone. Also used other sdcard from my android phone.

I'm having this problem too.
Any ideas?

Please take a look at this thread. I'm not trying to boost myself but keep you guys from having problems. I don't know if this is your problem (bad recovery from CWM) but it's been happening to a lot of smart people.

"E:failed to mount /sdcard (No such file or directory)"
I have been trying to flash the 3.2.2 ROM on my Verizon branded 4g+WiFi Xoom and I am receiving the same message when I choose apply zip from USB:
E:failed to mount /sdcard (No such file or directory)
I have tried three different microSD cards, 512MB, 16GB class 4, and 32GB class10. I get the same message no matter what card is tried. It does not seem to be able to see its own internal storage or the external microSD card.
I was following the steps and another odd thing is that I do not have the options to perform and Nandroid backup. I have the purchased version of ROM Manager but I need root access to be able to install ClockworkMod... Since my tablet is already at 3.2.2 all I really needed was root anyway so I can run Cisco Anyconnect VPN that required root.
Any tips on getting the Xoom to see or mount the SD card, either one, would be appreciated.
+++++++++++++++++++++++++++++++++++++++++++++++++++++
Step 1: Getting Ready to Flash Rooted Honeycomb in Xoom
1. Download the ROM Android-HC-3.2.2-Stock+Rooted-1.1-SOLARNZ.zip and save the file on your desktop.
2. Once done, connect your tab to the computer, mount SD Card or SD Ext and copy the downloaded Zip file to SD Card root. .
Step 2: Put Motorola Xoom in Recovery Mode
First you need to reboot Motorola Xoom in Recovery Mode, after that you can perform a factory reset on Xoom. Follow the steps below:
1. Turn your device on, then switch it back on
2. On startup when Motorola logo appears, press and hold Volume Down button
3. When Android recovery text appears, press the Volume Up button. Your device will now enter in recovery mode.
Note: In recovery mode, you can navigate up and down using Volume Up and Volume Down keys while Power button can be used to select an option.
Step 3: Take Nandroid Backup
1. Once in recovery mode, press & hold Power button.
2. While holding the Power button, press & release the Volume Up button.
3. Navigate to “backup and restore” and select it.
4. Select “backup” to perform your data backup.
Step 4: Factory Reset Motorola Xoom
1. Once Nandroid backup is complete, navigate to Wipe data / factory reset, then press Power button to select it.
2. It will ask for confirmation, select Yes, delete all user data option to factory reset Xoom.
Step 5: Flash Rooted Honeycomb 3.2.2 ROM
1. Select Flash Zip from SD Card
2. Then select choose zip from sd card
3. Select the zip file that you put onto the root of SD card.
4. Wait for process to complete.
And there you go! You are now on the latest Android Honeycomb version and are all set to explore what’s new. In case you are facing any issues or just want to thank the ROM chef. Do let us know in the comments section just in case if you face any issues while updating your device in the comments section as just in case if you face any issues then we will try to solve them at the earliest.

I suspect that you updated your recovery via ROM Manager to a version that doesn't recognize the external sdcard. You need to flash the solarnz R4C cwm
recovery v 3.2.0.0. Rom Manager is a pain.
Also please don't flash that 3.2.2 ROM. It will break your connectivity. If you have 4G, you can flash the Odachi kernel.

Had a problem similar to yours. Make sure you have your sdcard mounted completely in it's slot. Make sure you turn the xoom off when mounting.

4g xoom root failed
ok i attempted the 5 steps but i dont get an option for a backup nor an option to install zip file, the closest is 'apply update from usb drive' then i get the E:/failed to mount /sdcard (no such file or directory). card is mounted correctly. i bypassed the backup and just did the rest, same issue. should i keep it plugged into pc while doing all this, i plug in to copy zip file then unplug it.

Assuming that you have the correct recovery version installed (see my previous post), you should keep the sdcard mounted in your Xoom. Make sure it is actually mounted. A reboot with the card seated in its slot will usually do it.
You could at least read over this guide http://forum.xda-developers.com/showthread.php?t=1249798
and check the steps listed against what you have done. That often helps.

exactly what i needed detailed instructions for dummies. hopefully i will be succesful this time, taking a break for a day this stuff is for programmers, lol.

I encountered the same issue.
It appears the XOOM does not like SD Cards that were formatted using Windows
(or perhaps Quick Formatted using Windows).
Using a 4GB FlashDrive formatted as Fat32 using Linux (i.e. Linux Mint 17.3 Cinnamon 64 bit boot CD)
resolved the issue.

[Q] Can't mount sd-ext

I have a Nexus one running stock MIUI 1.7.1 with apps2sd and Aman Ra recovery. I attempted to activate cache2d, but after running the script the phone was unable to reboot. I moved the cache back to internal storage via adb in recovery and the phone now boots, but is unable to mount the sd-ext partition. When I connect via adb shell in recovery I am able to mount the sd-ext partition and view the files. I have attempted to run apps2sd repair from recovery as well as the actual OS, but both fail to have any effect.
Any ideas?

I have found a folder in mnt by the name "asec" which shows 220Mb free and extasec also with 220Mb free.
What do these folder mean?

[Q] CWM 5.0.2.0 Cant see SDCard files

I decided to install a new ROM and this is what I did:
-wipe data/factory reset
-wipe cache
-wipe dalvik
-format /system (which I'm not sure if I should have done)
Now when I go to install zip from sdcard, it shows files from my internal storage. It never did this before, I'm not sure what the problem is. I tried searching for it in the questions, but didn't find a solution. How can I make it list files from my external sd card?
There is a folder in there called external_sd but it shows no files. When I mount USB Storage, all my files are there.
Please help,
Thanks
Edit: So I was able to put files in the external_sd folder from my SDCard and install the ROM, but I still don't understand why it shows my Internal Files?

Problem partition 48mb

Hello, I have a problem with my one s, after the 's-off I installed the latest TWRP.
Mistakenly I did wipe the sdcard, now when I mount it by only 48 mb ...... How do I restore \ recreate the partition to 12gb?

here http://forum.xda-developers.com/showpost.php?p=45621060&postcount=68
If this twrp won't mount as usb storage, you should try flash twrp S4 in One_S_All-In-One_Kit_v3.5
If you can't boot in Android to copy a rom, you make this in twrp and Mount (push mount and back many time until you'll see usb storage in My Computer)
In command line
adb push HTC_One_S_-_MaximusHD_10.0.0.zip /sdcard/

and wait
HTC_One_S_-_MaximusHD_10.0.0.zip or your rom.zip, something like that.

I solved it by installing the recovery of maximushd via sideload Thanks Anyway!
