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
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)
fstab:
/dev/block/mtdblock4 /cache yaffs2 rw
/dev/block/platform/s3c-sdhci.0/by-name/userdata /data ext4 rw
/dev/block/platform/s3c-sdhci.0/by-name/system /system ext4 rw
/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:
Hi everybody,
I've seen this question asked a few times but none of the answers worked with me.
Trying to create a second primary partition in my internal sdcard with MiniTool Partition I messed up the phone that now doesn't recognize the internal storage.
From TWRP I get the error message:
Code:
E:Unable to mount /sdcard
E:Unable to mount storage
I can mount the internal storage via TWRP and access it from windows or linux, I have even formatted it several times in FAT32 or ext3 to revert to the original situation but there's no way to make it discoverable by TWRP or by the OS.
As the recovery doesn't see it, it's impossible to flash a new rom because there's no place where to save the zip.
Can anyone please give me a suggestion ? :crying:
[solved]
I managed to access again to the sdcard by flashing the stock ROM from Nexus Root Toolkit
Hi,
My Elephone P8000 was running Eragon 5.5 fine, then I wanted to flash visi0nary's kernel (_1014), so I used the method discribed (fastboot flash ...), and when I rebooted the phone, it just kept boot looping :'(
I can access CWM recovery still, but I can't mount /data or /sdcard, so it's pretty bad .... I tried to flash the stock kernel but it didn't change anything, I think my partitions are ****ed up !
Here is my partition table : i63.tinypic.com/2h3ztj9.jpg
When I try to mount /data with adb I get an invalid argument, and when I check "/dev/block/platform/mtk-msdc.0/by-name/userdata" with e2fsck, it says that the superblock could not be read or does not describe an ext2 filesystem ....
Please, can anyone help me ?
can any one help me

Solution for 0 MB storage in TWRP
Hi Brothers!
It's my first time posting here , so if i make a mistake i am sorry in advance for that.
Solution for 0 MB storage in TWRP is very easy.
You need to boot your phone into TWRP.
In 2nd step you need to go to WIPE option .
Select Data and click on FS Options e.g. trying to change its partition format, most phones use Ext4.
Do same with the Data.
And TADA!!!!
Your problem is solved
I hope it helps you guys getting answer after a long time because i saw it late. Sorry for that.

Hi my YU Yuphoria 5010 started acting up since last week ,when i noticed that the phone was restarting randomly and the settings was missing and even if i clicked on the settings logo in the notification panel, nothing would happen .So i decided to flash a Cusstom ROM instead and boot into recovery.While trying to wipe cache,dalvik and data I got an error message "uable to mount data,cache ,system(invalid argument) and internal memory* was showing up as 0.So i thought my phone was bricked and tried reviving it with the sd card method.But everything else except for system flashed , and got an error FAILED (remote: flash write failure ) just for system .Anyway now I could boot into recovery using fastboot boot command and the internal memory started showing up correcty. The fastboot command is the only way i could get into recovery, if i try power+volume down it would just come up with the empty battery logo. After this i installed qualcomm drivers and manually changed the driver to Qualcomm HS-USB QD Loader 9008 and tried flashing through QFil with a flashable stock ROM and ended up with the error message:"Download Fail:System.Exception: Unable to download Flash Programmer using Sahara Protocol** at QC.QMSLPhone.Phone.QPHONEMS_SaharaArmPrgDownload(String sFileName)** at QC.SwDownloadDLL.SwDownload.QPHONEMSSaharaDownloadArmPrg(UInt64& version, String armPrgPath)
Download Fail:Sahara FailSahara Fail".
But after going through some of the posts I found that my phone might not be bricked in the first place.My device just shows up as 'Android' under Other devices in Device Manager.
The following are the details from device manager.
Device type: Other devices
Manufacturer: Unknown

I also tried to restore through TWRP recovery using the back up my brother created on his YU 5010A to no success.Changing the file system type and back to ext4 also didnt help. I use a Windows 10 64bit Laptop.
What could I possibly do to revive my phone?Kindly help.

open TWRP recovery.Go to wipe section and select advanced wipe option here .Now select data and cache from check boxes.then click on change partition format.Select ext4fs .Wipe it then wait for sometime because sometimes it takes approximately 15-20 mins so be patient .It will successfully wipe and then you can see that everything is up to the mark !

Can't flash anything through recovery. (failed to mount "/cpefs" (Invalid Response)
I recently got this phone and I've been trying to install a custom rom, however, I can't seem to do anything while using TWRP. For some reason the file explorer shows no files and no /storage folder. It also says that the /system partition weights 0MB. I've already tried formatting the /data partition from EXT4 to extFAT, but it won't let me because it cannot mount the "/cpefs" partition, which I've been unable to find any information about.
I can flash the stock firmware trough ODIN, and I can flash the recovery. The internal storage works fine, but nothing shows up when I open TWRP.
I've tried formatting the data partition, repairing it, changing the partition format, wiping, installing a custom rom, installing superSU. But it won't allow me to do any of those things. Either "/data" can't be mounted, or "/cpefs" can't be mounted while formatting /data.

Which phone you're using?
J7 Pro?
Secondly make sure to enable OEM unlock options from the stock ROM's Developer option!
Thirdly check the recovery patches etc of the desired recovery's webiste (you're using) and flash it through the recovery if you're facing the problem!
It'll work, mostly some users said they fixed this by the above mentioned step!
If no luck, maybe someone will sort it out for ya, soon! :laugh:
Good Luck! :good:

Thanks for your reply. The model of the phone is SM-J710MN. The OEM unlock option is enabled, otherwise I wouldn't be able to flash the recovery. I am trying to use TWRP. Where would I find a recovery patch for this model?. Everything works fine in the recovery, but it won't let me wipe/format/repair or change ANY partition. It can't mount anything, and the error that I see the most often is that it cannot mount the /cpefs partition.

try flashing a lower version of the same frimware you've already installed e.g if the latest is nougat 7.1.1 with the recent security update, try flashing with another nougat version that is lower to the recent one's security patch #
