[Q] Can't mount /sd card - Galaxy S II Q&A, Help & Troubleshooting

I am following the steps of rooting to a "T". I successfully got CWM Recovery installed. However, when I go to backup & Restore in Recovery it will not allow me to create a backup because it "can't mount /sd card".
Since this phone has internal storage and not an SD card, is there any way for me to fix this?

There is a slot in the phone for a MicroSDCard, most versions of CWM do however default to the internal memory for that option though.
But not all versions, it's possible you're using one of the few that tries to mount the MicroSD as /sdcard.
Maybe try flashing the Siyah kernel via Odin, it's compatible with all(?) SGS2 firmwares as far as I'm aware. It has a different version of CWM built in.
You could use an adb shell to see what's going on but most folks don't seem to know what adb is any more.

[Q] Installing a ROM using External SD Card

I recently made a mistake on my phone & got it stuck in a boot loop. I figure the easiest fix is to just wipe system & install a new ROM from the CWM Recovery Menu. My problem is I cannot access the external sd card.
When trying to navigate install zip from sdcard > choose zip from sdcard > external_sd/ it simply returns "No Files Found". I'm assuming because that's probably just a symlink.
If I go to Mounts & Storage and attempt to mount /sd-ext, I get "Error mounting SDEXT :!.
Maybe I'm going about this the wrong way, so any help would be appreciated. I'm still fairly new to the whole Android scene.
I should note that my USB Port is broken so using that is out of the question. I've already attempted twice to replace it (damn thing wont desolder), but that's a whole other bag of worms.. That I won't bother re-visiting unless it's my only option.

You install a rom with cwm through the internal sd, not external; so yeah, you're going about it the wrong way.
*tear* Just what I didn't want to hear.
a little help
you could try flashing a different kernal ie siyah pr cm9 these have different versions cwm included so you might be able to access your ext sdcard just a thought.
It depends on the version of CWR you have flashed. Whenever I run ICZen the version of CWR (5 something) that Deficient Development bakes in lets you flash zips from the external SD; very convenient.
Can the OP use DroidExplorer, and transfer a rom to the internal? I've not used DroidExplorer, but have heard it talked about.

If there isn't a ROM on the internal SD card to install from recovery, and the current kernel version does not support install from the external SD. Then I would assume you would need to ODIN to stock.
Good luck!

Why can't you use something like Dropbox or Box and upload it from your PC, then download it to your phone and transfer to the sdcard of choice with a file explorer? Then flash away. In fact I just did this the other night bc I was too lazy to go to my PC and hook up my phone. I just uploaded it with my tablet and then downloaded it to my Vibrant.
Edit::: I just re-read your OP.
If I go to Mounts & Storage and attempt to mount /sd-ext, I get "Error mounting SDEXT :!.

This is NOT the external sd card. SD-ext is another partition that has to be set up on the sdcard with something like Gparted or MiniTool Partition Wizard. It is for when you do not have the standard Samsung 2gb partition or the /datadata partition set up. FWIW, I have never seen this particular partition set up in the Vibrant.
I can't remember what the actual Mount option is in CWR but I definately know this is NOT it. Not sure if you remember seeing it or not but when you do a Nanadroid backup, it will always skip the SD-Ext part b/c there is nothing there. This is more mainly for older phone that were running Eclair and did not have native App2sd support. It was used as a hack to force that support.
i think go to a shop get your USB port repaired and get back to STOCK if you dont have any rom on your internal sd or do a (wipe cache etc etc) so that the phone will run on the ROM's kernel

[Q]E:can't mount /sdcard/

After using Odin, I have this problem
'E:Can't mount /Cache/recovery/log
E:Can't open /Cache/recovery/log....'
Then I wipe it. It is success.
But when I choose zip from sdcard
It said E:can't mount /sdcard/
How can I solve it?
I can't boot my gs2 now!
Answer me please
Just try to reflash with odin most of the times this solves the problem.
if not try another firmware (rom)

I can't boot and can't read my internal sd, how can I flash another rom?
Using CWM, you can mount /sdcard.
Check mounts and storage menu.
Also try "Mount Usb storage", connect to pc and check if comp detects your phone.

E:Unable to write to ums lunfile(No such file or directory)
Try flashing one of the rooted kernels using Odin.
Sent from my GT-I9100 using xda premium
Currentlyhaving the same issue.
This is a kernel issue. It happened to one of the 2.x Siyahkernel beta versions. Simplest solution is to boot the phone and use CWM to flash a different kernel using the tar format (instead of the zip format good for use in recovery mode) (flash a kernel version that's known to be without this problem).
If you can't get past the boot screen, just use odin. But then if you can't get past the boot screen you probably need to flash a ROM over anyway.
I am having the same issue with my internal SDCARD
I cannot access my internal SDCARD. When I insert my external (/removeable) sdcard, recovery sees that as the SDCARD.
I have tried to mount/ dismount/ usmount the internal SDCARD - same error.
THIS is the TMOBILE T989 and we got it yesterday - brand new.
So, I did get it to work from the removeble SDCARD, but I am so use to using the internal SDCARD on my VIBRANT as the primary resource for ROMS, etc, and the external SDCARD as a backup - that it is kinda strange to work now with only one SDCARD (the ext).
It must be something in the recovery that does not see the primary SDCARD...
CAn anyone help, please?
Note that CWM 4 and CWM 5 behave differently with respect to internal and external sd cards (well CWM 4 simply doesn't do external sd card). It'd be your best interest to flash a kernel that comes with a CWM version 4.x.x and for sure internal sdcard will work.
In CWM4, internal sdcard is /sdcard. External card is /emmc. (you can only format external sdcard but not write to it nor mount it.
In CWM5, you can restore nandroid backup from internal sdcard (but you can flash updates from both) . And in the CWM app, default backup location is the external sdcard.
Those who are having problems with CWM 5, flash this version of CWM from your CWM!

Rom Manager with CM7

Does this work on the Nook Tablet? Mine doesn't appear to function when I try to do a backup.
ROM Manager
I am using ROM manager on CM7 alpha12 without problems. I use it to boot to CWM recovery and back. I use TB and CWM for backup so I can't verify backup with ROM manager.

So you are saying that you did the newest CM7 upgrade and your CWM works without using a SDcard? When I try to do a backup in ROM Manager my tablet will reboot and then it comes up with a screen saying to power cycle again and if this don't fix it call B&N support
ROM manager
Correct - if I want to use CWM I just start THE RM app and select to reboot to recovery. The tablet reboots into cwm and I do what I need,for example,backup and repartition data and media then select to reboot to regular CM7 ROM w/o changing SD card.

Bummer Mine doesn't work and I have no idea how to fix it
I cant do a backup directly from ROM manager either.
BUT if you follow his directions and boot into CWM first, you can do a backup from there without a hitch.
If you want to name it yourself you need to go to the file in your file manager of choice, and change it there.
Can someone tell me where backups to internal storage are stored?
Thanks.
sdcard/clockworkmod/backup
I do believe you need a sd card for your backups.
It sounds like you do not have one, thats why you are not able to do a backup?
I have one and it creates a backup via internal. But when I try to backup to sd card, it tells me it failed to mount. So I backup via "internal storage." I can then go to restore and I see my backup from the internal there.
Dont have my tablet in front of me but it somehwere like: /mnt/emmc/clockworkmod/backup
You should find a clockwordmod in that general area if its like CM7 for other devices
You can manually mount and unmount your SDcard through clockwordmod as well. Have you tried to mount it manually before backing up
I just decided to try it again, booted into CWM and clicked "backup" and now its backing up to sd (free space showing as 30017MB, 32gb card so that makes sense).
Earlier when I tried manually mounting the sd card it was giving me an error (failed to mount). I have no idea what fixed it but its working now and I'm sure I'll be able to find the sdcard backup at the very least.
Thanks for your help.
The SD card doesnt always mount on its own in these devices. I HAVE noticed that..
Hell,it doent even want to mount with guidance, as you have just shown, and I have experienced as well..
Glad it worked this time..
sd mount
As has been noted in other threads, sometimes you have to take the card out and reinsert to get it to mount. I have had times when using the CWM menu option to mount sdcard failed. Turn the tablet over,click the card out and back in and it will mount

Definitely the case, but when in CWM it doesnt always mount even by ejecting and re-inserting the card.
At least from my experiences.

[Q] Fascinate won't mount sdcard with CWM

I am re-rooting my Fascinate, had to return to factory settings via odin due to my phone not booting after trying to flash a new ROM.
SD card will mount fine and be recognized in Fryo, but when I reboot into recovery CWM will not mount the SD card.
So now, I cannot flash superuser, and cannot get the phone rooted. Any ideas?
Try a new sdcard. It must be class six or higher.

[Q] 'Error mounting /sdcard/' Help

Hi guys,
My SD card got corrupted before flashing a rom, so I'm a bit stuck (I can access the CWM menu, the kernel is fine).
So I formatted the card to FAT32 (tried other formats) but when I try and flash an update.zip from it I get
E:Can't mount /sdcard/
So I'm thinking, are there some files missing from the SD card that CWM/android need to interact with it? I can imagine these files were wiped when I did a format. Like superuser files or something? You know also, those hidden files beginning with '.'
I've tried all the usual methods like formatting using SDFormatter and stuff - still, CWM can't see it (my computer can if USB is mounted). Am I right in thinking I need some kind of system files on the SD card?
Any help?
Thanks in advance
the best would be paid copy a rom sd card and flash, or flash a rom stock also either ics or gb and see if there cel recognize SD can not think of anything else. :highfive:
Ok, I guess I'll try that if there's nothing else. If I flash an official .ftf with Flashtool will I need to do anything to my bootloader (currently unlocked)?
Edit: I've been reading around and it seems almost certain that my sd card just needs some vital files on it for CWM and android...
Try by simply reflashing any kernel with cwm if your sd card is readable from pc it is not corrupted, it's more likely somethign wrong with cwm, you should be able to fix reflashing kernel which shouldn't be much of a prob since you have unlocked bl

Hey nice idea, but I tried that earlier and multiple kernels give the same error - it can't be CWM, it must be the SD card (or what's not on the SD card).
Edit: I've tried chkdsk and formatting to a variety of systems using a variety of partition managers, nothings works, my phone just can't mount the SD.

First backup your nandroid backup (if you have one) in a secure place (not the sdcard)
Put your sd card on some other android phone with cwm and format it from the cwm mount/storage option.
if you don't have a nandroid backup skip the next two steps.
mount the sdcard in your computer and create two folders in the sdcard (a folder inside a folder) name the parent folder as "clockworkmod" and child as "backup" .
Put your nandroid backup in /sdcard/clockworkmod/backup/
Now put the Rom zip file you want to flash in the root of the sd card
Power down your phone.
Put the memory card in your phone
Boot into cwm and try to flash the rom.
If the second step fails with "error mounting sd card" try with another memory card or with another phone.
