[Q] "Can't mount sdcard" error in CWM

I've seen this error elsewhere, but no solution. I'm running PRIME 1.4, want to upgrade to 1.6.
- I used the nvflash method. I re-did this, obviously that didn't work.
- I tried formatting the SD card via Windows and via CWM (which didn't work, because it couldn't mount it...duh). Used the default FAT32 settings to format. For others, this seemed to be the fix.
- I CAN read the SD card on the tablet once booted up regularly. I can also mount the storage on my PC.
Any ideas? Thanks in advance.

So I tried a different sdcard (8GB, if it matters). No issues. No idea why this worked, so I guess the mystery is unsolved.

Probably partition of your sdcard. Try reformatting it to another format like NTFS or something?

In fact, CWM can't real actual SDcard (dock slot), it read the MicroSD only (the tablet slot)
Try putting the zip at the root of the MicroSD, and launch CWM

For me it´s doing the same - can´t mount SD card. I have microSD card that I have formated into FAT/FAT32/NTFS - nothing worked. I try to put it into SD card adapter and nothing too...
Can someone tell us please, where is the problem??? I have root, flashed cwm 3.0.2.8, standart ROM...

MicroSD needs to be formated into FAT32 and only this format
If you read the post above yours, you would have also seen that the SDcard slot on the dock DOES NOT WORK in CWM

Yes, did this. I wasn't messing around with the dock, just the microSD in the tablet itself. And yes, the .zip was in the root directory--though it's not like I was able to get this far. I was not even able to see the root directory, at all.

Plug it in while android is running, and check if the MicroSD is seen in /removable/MicroSD
If, yes, that's pretty weird. If not, try another MicroSD

I had the mounting issue as well. But I formatted my micro SD card with SD Formatter (I am not allowed to post URL as a new user ), then it can be mounted.

myode is right, use SD Formatter 3.0 will fix your problem.
It use low-level format, where windows format don't.

I came across (i can't remember where exactly) some people swear that by formatting the microsd card in a android phone, the card no longer exhibit abnormal behaviour in the tf101.

[FIX][CWM] Error: Unable to mount SDCARD in CWM (and CF-ROOT)

Hi people!
I have seen many people have a problem with the above mentioned error in CWM. Although there are any threads on the topic, none of them are really clear (and often speculate) the method to fix it. And there is a lot of confusion regarding the "sdcard" in the i9003. This is my attempt to clarify and provide a reasonable fix (which worked for my Class 10, 16GB Micro SD (SDHC)).
It goes like this:
-> Boot into CWM recovery
-> Choose any options pertaining to the external sd card (such as backup, restore or install file from .zip)
-> The command returns with an error about how it can't mount "sdcard".
Now, there are a few thing that you have to be mindful of:
1) The "sdcard" mentioned in CWM for the i9003 is actually the external sd card.
- It is done this way so that everything works with the external sd and not with the internal 2GB sd that is present on our phone.
2) The internal sd is referred to as "sd-ext".
3) This pertains to the CWM of our phone. After booting into Android, it is back to "normal".
I tried to do a format in Windows 7's default formatting tool with FAT32, exFAT and NTFS (just eliminate the possibilities) with "default allocation size". It didn't work. Even choosing a larger allocation size did not work.
The Fix:
-> The optimal recommended filesystem for an android SD Card is FAT32.
-> Using the "SD Formatter" (version 3.1 as of this writing) from the SD Association ended up solving my problems.
-> The download link, for Windows (A MAC version is also available), from their site is here. You have to click "I Accept" and accept the terms of the EULA (but who really reads those things anyway ) ?
-> Use a card reader (using your phone is not recommended), make sure you have selected the right card and that you have backed-up all the data on your card (incase you didn't know - formatting erases all your data!).
-> I chose "Quick format" under options and made sure "Format Size Adjustment" was off (These are available under "options").
-> It's done in a few minutes, and it works GREAT! :-D
Cheers people! Hope this clears up some stuff!

This thread deserves to be made a sticky thread...
Moderators please make sure to consider this
Btw - nice job dude you explained it all very well!
Tapashocked via my gt-I9003 with a random keyboard of my choice !

Finally solution came..it works like a charm...thank you so much Bro..

I was bugged by the same problem a few moths ago....
I solved it by Going to Settings > SD card ad phone storage >SD CARD> Umount sd card > Format SD card....

@Lord: thanks mate!
@Symdroid: your welcome! Glad to have helped!
@Neojith: Yeah that usually works, but for some odd reason it didn't work for me last time.
Also, this works without fail even if your SD card is unrecognizable (or comes up as corrupt/damaged) in Android but is detected on the computer.

Man i dont hav any card reader....why cant i do this while it's inside the phone? :-(

Give it a shot... It may work (but be sure you're formatting the right card)!
I recommended a card reader as it is faster, and in most cases the card wasn't detectable by Android but was detectable using a card reader.

Got cranium ROM 3.1 and its not working on my phone. It shows the drive in the PC but i cannot access it. But the phone still reads whats on the SD card. It works well before with kPE...

kudos Erahgon, it worked!
FYI I didnt even use a card reader, used the phone itself (too lazy to search for a reader at home)

Srry guys, was outta town for a few days!
@vadexlux: Good to hear that it works from your phone as well!
@lbraddx : If it's not accessible even in Windows, your card is probably corrupted. Do a quick format in Windows, then use a data recovery software to recover your files. After that, format using the method in the first post, and remember to back-up your files.

Can you access the card from your phone? Can you access it from your computer?
What are the specs. of the SD card?

cannot access from the phone. but when i flash with odin there is part saying 'error can't mount sdcard-skipped wipe data' but when i check the sd card from my pc its empty and i lost all my file in sd.
here another weird thing, you said the 'sdcard' in CWM is the external sd. I can't mount 'sdcard' but I can mount 'sd-ext'; when i took out my sdcard then I can't mount 'sd-ext'. so I think in my case 'sd-ext' is my sdcard. thanks for replying though. can you figure out my problem?

Flashing with ODIN? What were you flashing with ODIN? When you flash with ODIN it doesn't do anything to the external-sd card.
Have you done an internal-external sd swap? If so, and you want to flash a new firmware using ODIN, you must re-partition (i.e. Use the latona pit file) and then proceed with the flash. After the flash, you may once again swap the external and internal sd cards. I haven't tried this, so this is just my best guess. If this doesn't work, try using your old vold.fstab file (read this thread for more details).

still no luck

Fascinate owner here. Had the same issue with CWM red (3.x) and Green (4.x).
All I did was reformat the card in Android. You have to unmount it in Settings > SD Card. Then simply Format. All your data will be erased but CWM will be able to read your card again.

WOW... I have THAT trouble too (on a I9100!), read this (googled) post and think.. "hmmm.... all other works fine with the ext. SD-Card... that can't be the fix..."
BUT i test the fix and OMG!... Now all CWM troubles gone! PERFECT!
Thank you very very much! I love the XDA community! *smak* ;-)

Is there any way to do the same for the internal sdcard coz my external sdcard reads fine but internal phone memory as well as internal sdcard are corrupted!

WOW
hi dude..its works like..hapi man!!!Thanks alot!

Changing sdcard name

Hey,
I would like to install the android revolution hd but I got a weird problem.
In my tf101 the main storage 16gb is somehow (dont know why) called sdcard and when I put real micro SD to the tablet - it is called MicroSD instead of sdcard.
Now, because of that I cant instal new rom cause it always thinks i have not sdcard in. (in rom manager pro - it sees my sdcard a the main storage called sdcard)
In root explorer I can change sdcard into something else but cant change MicroSD into sdcard. Do you have any idea what should I do?

Do not use ROM Manager. And what you're reporting is the normal storage for the TF101. sdcard is the internal storage, microsd and sd are the 2 extension slots.

ok then, why my android cant see any sdcard when im in recovery mode (without using rom manager, and I tried 3 sd cards yet), Oh and btw I got Clockwork recovery mod 6.0.2.1
Hmm, is that possible to change the rom into revolution hd with easyflasher ?

There should be a menu in recovery to attempt to mount the card. Maybe advanced menu I think. Try that.

well, I tried but there is no such thing in advanced also. So what about easy flasher, can I try with that?

Use the mounts and storage menu and you should be able to manually mount your microSD card.

problem solved, i used goomanager to instal other flash which recognized sdcard,
it turned out that reading alot of old stuff actually helps alot xd
thanks for all anyways

[Q] tf101 internal os installation without os

Hello
I wanted to install Katkiss on my tf101. I wiped all the things I had to and headed to the installation part but my tablet couldn't recognize any external SDs. I use TWRP so it should have been supported.
I could get into apx mode but I don't know if I can put files on my tab from there. My PC can't recognize the tab if I try it in an other way. So someone can please help me and give some solutions for reaching the internal SD with a USB connection?
I guess I can install the files from TWRP after it .
Any help would be appreciated. ?

If TWRP is working, put files on a microSD and install the OS. Otherwise, you will need to use APX and something like EasyFlasher to install TWRP or the stock firmware.

I have spread installed TWRP as I remember I also used EasyFlasher to do it. As I mentioned my tf101 couldn't read any SD card that's why I've asked for a hint to put the katkiss files on my internal card.

How is the microSD formatted?
Did you boot to TWRP after installing the microSD?
What version of TWRP are you running? Not all of them support ADB via USB.

My TWRP version is 2.2.1.4 and the SD card is "general hierarchical". As I know I need a FAT32 card to make it work but I couldn't find a way to format mine. If you know a way to do this than it's also good for me. I also tried a FAT32 pen drive through the keyboard but it - of course - didn't work.

I don't have a card reader and my PC didn't find the card when I tried with a phone having the SD card inside.
Do you think it might work if I format my external hdd to fat32 or the tf 101 won't recognize it?

Hi, yes you're right, more details:
I'm on TWRP 2.6.3.1
Zip files was on micro SD card formatted in NTFS.
And what I tried with no success is to find teh file on sd card location.
So I test FAT? On SD Card?

That TWRP version is very old... but should be good enough for wiping.
How did you try to find the file "on sd card location"? Using "Select storage?" Or did you mount using the mount page? In which directory did you look? external_sd or whatever it's called?

Download CM11.0
Download GAPPS
They are installed at the root of both cards, there is no other files or folder in it.
I start in TWRP and then click install icon and look for these files everywhere and found nothing.
When I cick to mount icon, I cannot mount the micro SD or the SD cards.

when you enter twrp you should press on install, then there is a tab that says choose storage press on that and choose sd card, then carry on as you have been doing. twrp doesn't automatically show things on your micro sd card
