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?

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?
Hi i flash locky another CWR AND IT'S FIX LUCKY ME B^)

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:

I've tried all the recommended procedures garnered from the first 10 or so pages in google, xda, cyanogem forum, etc:
Restore from nandroid: Not possible, can't mount the SD,
Wipe/Reset: can't wipe /media as sd card won't mount,
partition sd card from within Clockwork: indicates success but does nothing,
format from within clockwork: unable to mount,
repartition using adb: works, parted can see them, I can move files to from, but the phone will not mount,
clearing fstab: no effect,
Fastboot works, but I don't have the proper images. ADB works, as do the installed utilities. Have not tried ODIN as again, I don't have the proper images. Should I attempt to compile my own images from source?
Update: SOLVED, Microsoft Windows. To whom it may concern: I was able to mount the /dev/block/platform/s3c-sdhci.0/by-name/media from two different laptops running OSX and Fedora/Ubuntu then successfully been able to partition them with fat32 as the ClockworkMod (and maybe Cyanogen?) expect with 0 progress. Then I pulled out an old Windows machine, installed the JDK/ADK's +tools and performed the same procedure and that time it worked. I'm uncertain as to what particular quality a 'genuine' Windows formatting provides, but either this phone or the particular software combination I'm running require it. I was able to mount & re-partition the /sdcard in Clockwork, then manually remove rebuild them and upgrade to ext4 using tune2fs as usual. In the interim for work and such, I had to find a surrogate (for the SIM) and could only find and old k750i (which still had a full charge and worked flawlessly all day, btw). Wow phones used to be small.
I think I was missing something about the way ClockworkMod handles fstab, because everytime I would modify it specifically to the specs I passed to parted while creating the partitions with mkpartfs, it would either ignore or overwrite them. So be careful messing with the sd-card, the S's aren't like the One's in the sense that if you screw it (the sd-card) up or it goes bad you can't just take it out and format it in another machine/phone, you have to appeal to ClockworkMod. ODIN $ucks by the way, I found fastboot to be much more effective.
If you format the sd partition ext4, then you should change the fstab too.
from
Code:
/dev/block/platform/s3c-sdhci.0/by-name/media /sdcard vfat rw
to from
Code:
/dev/block/platform/s3c-sdhci.0/by-name/media /sdcard ext4 rw
or from
Code:
/dev/block/platform/s3c-sdhci.0/by-name/media /sdcard auto rw
The 2nd last entry there is the file system type.
Likely, this would have solved your problem.
Of course, I don't know, whether the recovery has the vfat type in fstab. You might have to change it there too. On my linux box auto works very well in fstab.
Of course, if you partition your sd partition ext4, you won't be able to use it as usb memory from windows. (At least I am pretty sure you can't, haven't tried)
Well of course I couldn't let it die, I went back and started tinkering again now that I have a way back. I can't change the fstab it seems, whatever I change it to gets over written everytime either Clockwork or the Rom starts. It's weird, I know I'm missing something and I don't know much about CWMod. (had Amon_Ra on the N1, which had the nifty fsupgrade script)

I'm quite familiar with unix style fs and fstab, it's the stubbornness I'm not used to. I'm also spoiled by vi and nano. CW has some nice scripts built in as well though.
Hello,
After several problems with S2E and apps disappearing, I decided to completely erase and format my SD card.
I'm using CM 7 on HTC Desire (working quite well).
Now I'm facing a problem : I can mount the sdcard and sd-ext from the recovery. But only the sdcard is mounting automatically upon startup.
When launching S2E, it doesn't show the ext partition.
When I go to the terminal and manually mount (mount -w /dev/block/mmcblk0p2 /sd-ext), it works, and then S2E shows me the space available.
But apps still get installed on the "real" internal memory, so rapidly showing a "low memory" error.
I guess rebooting should enable the S2E memory management, but as long as the sd-ext doesn't mount on startup, it can't do anything.
As /etc/fstab is mounted as read-only (and it's starting to be a mess on my phone), do you have any solution ?
By the way, although it's an ext3 or ext4 partition (I don't remember), mounting without giving the type makes it mounting as ext2 (and working perfectly).
Regards,
Jonatan

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
This is a very annoying issue but I have not found any thread about it.
I'm trying to upgrade my external/removable sdcard for an android 6 device.
The new sdcard gets mounted to /mnt/media_rw/XXXX-XXXX (i.e. not 0123-4567), so no app works as files can't be found.
The linux way (ln) wont work. Simply creating /mnt/media/0123-4567 causes bad bootloop on my device. This suggests that FolderMount app or Magisk modules such as fbind are a bad idea. selinux is enforcing.
It appears that Android assigns different mount points are to different sdcards and the first sdcard always gets 0123-4567. It that's right, Android probably stores sdcards' identifiers so as to know which mount point to use at boot time. So, deleting the identifiers database would probably mean that the next card inserted would get 0123-4567 as mount point.
I have looked at the data of com.android.externalstorage, but there is nothing there. I don't see other obvious candidate apps.
Where is this ext sdcard data stored?
I was wrong. Android sets mount points matching sdcard uuid
How to change vfat partition UUID?
How do I change the UUID of a vfat partition? For ext2 / ext3 / ext4, this is done with a simple: tune2fs -U <new-uuid> /dev/<partition> Is there a similar command for vfat partitions?
