Blank SD card/ Unsupported Filesystem

Using Cyan's tutorials on his wiki, I rooted successfully and am now running Cyan's latest, with his 1.4 recovery.
I finished running the apps2SD tutorial and now the print command reads 2 partitions
Number Start End Size File system Name flags
1 17.4kb 7587MB 7587MB fat32 msftres
2 7587MB 8099MB 512MB ext4
But I'm getting a notification as soon as it boots into android that says.
Blank SD card
SD card blank or has unsupported filesystem
All the amounts under SD card & phone storage settings menu reads: Unavailable. And my internal phone storage reads 46.82MB

Download the recovery image in my sig and use that parition manager.

Thanks alot evilkorn. Worked perfectly.
Cyan should implement something like that into his recovery

I think I spoke to soon though. Everything works on the phone, but it wont mount on WinXP.
It mounts on my mac, but when i try to transfer anything to it it gives me an erorr.
The Finder can’t complete the operation because some data in “data” can’t be read or written.
(Error code -36)
"data" (in parantheses) Is the name of the folder im trying to copy to the SD

Mount the file system as -rw, you should be able to find the commands on here some place. I use root explorer so I don't need to remember it =p.

Is it easier with root explorer? Mind telling me how to use root explorer to mount it as -rw like you said

It says remount as R/W.

to mount as r/w in terminal or adb shell:
Code:
mount -o rw,remount /dev/block/mtdblock3 /system
to mount as r/o in terminal or adb shell:
Code:
mount -o ro,remount /dev/block/mtdblock3 /system

You can do this in ES FileExplorer too and its free.

having same issue
I didn't do anything fancy really.
I'm running a moto droid with the 2.01 update that I received over the air.
Today I launched twidroid and it completely ftoze the whole phone, non responsive even on the hardware buttons. I did a battery pull and upon restart the notification window says sd car blank or file system unsupported.
Tried browsing sd card with astro and it shows blank.
Any suggestions? I have a ton of photos and application settings I don't want to lose.
Thanks in advanced!

Reformatting will pretty much guarantee that I lose my data. Any other suggestions?

this happened on my g1
I know the poster was getting flack for having 2.01 on his droid but I have cyanogen 4.9...... whatever he's at as of 12/25/2009.
This happened to me I was sending an sms it froze I popped the batt like I've had to do in the past except this time I'm getting a blank sd card error on boot. B4 I repartition and format is there a recovery option? Preferably something I can do from console since I'm in transit from the holiday?
I imagine since we used similar procedures to fix our "smart" phones maybe our recover procedures will be similar.

My phone is not rooted, and i don't know what to do!
I tried to format my sd card, i have tried with another card, and nothing; the same message!
I don't know what to do in this case....maybe if you have any solution to my problem.
Here is some info about my phone :
Model number : T-mobile G1
Firmware version: 1.6
Baseband version : 62.50s.17U_2.22.19.26I
Kernel version : 2.6.29-00479-g3c7df37 [email protected]#19

anyone ? !!!!!!!!
i really need some help!!!!!
any solution to root without sd card ?

[MOD] Mount SD card as a folder of internal memory for CM7

This seems to be the best solution if you just want to stock mounting in cm7, I don't know if build.prop changes with every new nightly so you'll probably have to edit it after every flash.
Stikkontakt said:
SOLUTION:
1: Create a folder in your internal SD Card (in my case "ExternalSD")
2: Edit vold.fstab:
Code:
dev_mount emmc /mnt/sdcard/ExternalSD auto /devices/platform/tegra-sdhci.2/mmc_host/mmc1
dev_mount sdcard /mnt/sdcard 9 /devices/platform/tegra-sdhci.3/mmc_host/mmc2
3: Edit /system/build.prop
Code:
# Mount the internal SD card, too
ro.additionalmounts=/mnt/sdcard/ExternalSD
your external sd card is now mounted inside internal sd card. If you go to settings/storage, it will come up as unavailable, but the external content is inside your selected folder

nomedor said:
After that you can mount external sd as a folder of internal by using this command in terminal emulator:
Code:
mount /mnt/emmc /mnt/sdcard/_ExternalSD
The problem is that it can't survive boot and you have to write this command by hand every time. I tried to make it run on boot by adding the command in \system\etc\init.d folder as a text file but it didn't work, although it should.
Any help is welcome

That's why it didn't works!
Thanks for bring it up! I hope someone will help you becouse the way stock roms mount sd card is way better!

pushing it up, since this here is an interesting topic. It does indeed make more sense to mount sdcards like the stock roms mount it...
Hopefully someone can figure this out.
Also i noticed that if you do not mount emmc/_ExternalSD it gets recognised by the pc and otherwise not. This could be coincidence since i'm struggling hard with mounting my sdcards to my mac...

Unfortunately you are right, after this trick pc can only see the external sd card!
Maybe this isn't the right way to do it or somehow it needs to automatically unmount before you connect the phone on pc and then on disconnect remount it again.
Sadly my knowledge is limited, but I think that a real developer can do it in a heartbeat.

I'm not a real developer, but I remember that the modified fstab has to be put inside the kernel ramdisk.
I have found these two perl scripts somewhere on the net. They can be used to extract and repack the boot image. Could be possible that the base address has to be modified to work on the O2x, haven't tried it myself yet.
Zip including the scripts are here:

This is easy peasy lemon squeezy . For me at least since ex-dev.
Instructions:
Get root explorer (cba giving adb commands on my phone)
Mount r/w
Go to etc/vold.fstab
Mount r/w again
Long press the file and click open in text editor
Now at the bottom swap the mounts. Sdcard to /mnt/emmc
And
emmc to /mnt/sdcard
Save and exit.
Delete backup and reboot.
I will post a flashable zip if you want soon.
DONT FORGET TO THANK ME!
EDIT: just read first post properly. It should work on every boot. It is for me on my g2x. Try my easy method

The problem is that I can't find a way to mount external SD in "/sdcard/_externalSD" from vold.fstab where /sdcard is internal memory, just like stock rom.
It should be possible...

I've already tried that. I can't understand why people are not interested in this

yeah, there are almost no applications which can use /mnt/emmc. So 1 partition is almost useless at current situation.

Any progress?

Stock's ROM vold.fstab is mounting /sdcard/_externalSD but this is not working on CyanogenMOD, it could be a CM7 "problem" after all!

No update? CM7 way to mount sd sucks IMHO!

if you want to test it (please do a nand backup before!), than try my kernel and add the -internal flag to it.
Download this
rename to vorkKernel-080611-internal.zip
and flash it.
It is untested, because I don't want this behaivour and I made it because a user requested it. So no gurantee that it will work etc.

Bennee:
From what i see in vold.fstab file in the flashable zip it only swaps paths...
Any luck mounting external sd in "/mnt/sdcard/_externalSD" ?

there is a additional mounting script + some permission fixes. Should be called on every boot up (mount /mnt/emmc /mnt/sdcard/_ExternalSD).

But it doesn't... _ExternalSD is empty with your kernel.

OS or device

I'm not sure if this is even the right kind of forum to post this, but I imagine some dev has had this. When trying to move files onto my device using dolphin file manager on Ubuntu with KDE desktop the files never transfer. Anyone know why this is and if I can fix it. Is it a problem with ubuntu or with the device(xt860) It's a pain to switch to windows just to move a file. If a mod wants to move this thread that's cool. I wasn't sure where to post so here it went.

do you put the phone in mass storage mode?
is Ubuntu giving you any errors?
do you unmount it before removing the cable?

Curious, do you have a memory card and reader available to test out? Imo try putting files on the card with the reader in ubuntu and see if you can read them on the phone, if not it's ubuntu.

Are you mounting the sdcard or internal storage?

With ubuntu and the phone in usb mass storage mode he would be auto mounting both, although that does bring the question to mind ... Are you sure you're looking at the right disk on the phone?

How do you know it didnt transfer?
On the phone, internal storage is /sdcard, external is /sdcard-ext. Are you looking in the right place?
Sent from my DROID3 using Tapatalk

I tried it multiple times, and I checked both the internal and external sdcard each time, just to make sure I didn't drop it in the wrong one. I also tried moving it through terminal commands just to see if it was a glitch in the dolphin package. I also tried another package "file manager" or something. I'm not at home to check the name. Everytimenothing. I tried unmounting the drives, and just disconnecting. Everytime, nothing. Did it in windows, and copied over right away.
PS. I also tried both moving, and copying, both show it on the card, but when I disconnect, its not there

[Q] How to Mount Read Only External SDCard?

Is there a way to force mount my external SD card as read only? I'm fed up of constant loss of music and the lost.dir file going up. I have tried all sort of troubleshooting, this is just an android problem ( I never had an issue with my blackberry ).
I don't use my external SD memory for anything else since the phone has built in 16GB anyways, and was hoping there is a way to lock writes to the external card. I am rooted. Thanks!

You should be able to use root explorer or a pc, and change the properties of your music folder to read only. Root explorer option is under permissions with a long press on the folder, groups needs write unchecked, not sure what a read only sd card will do, might generate errors, not sure. Quick question, did you reformet the card using the cards format option when you moved it out of your blackberry?

This ^ You could also do it via a command prompt or disk management. Depends on your skill set.

You can't set those properties on an SD Card. I will try to set the read-only checkmark on the filesystem, but it is FAT32 and file permissions aren't very good... I tried using an NTFS filesystem to no avail...

busybox mount -o remount,ro /mnt/sdcard-ext , it could be added to /system/bin/loadpreinstalls.sh for a permanent solution.

Could we just change permissions on the folder we keep music in? That way the phone can still write to the card if needed
I tried running chmod 055 /sdcard-ext/Music but when I check the permission in my file manager nothing has changed
Sent from my rooted xt860

Endroid,
The problem is that the FAT32 filesystem is too basic for anything including file permissions. The filesystem becomes corrupted because it isn't being properly dismounted (for whatever reason), so even if you denied write access to specific files using a different file system, I'm sure the the corruption would still happen.

So ultimately no matter what I do my music is gonna keep moving to lost.dir. even if I reformat to NFTS
Sent from my rooted xt860

The phone doesn't even read NTFS... It only takes FAT32 as the SDCard. The best option is the one that was outlined by eww245, mounting the card as a read-only to avoid file corruption.
Although I am relieved to see that my device isn't the only one that is experiencing this sort of issue.

has anyone tried remount the sdcard-ext yet. does it work and did it cause any issues?
also will this affect the usb transfer
edit: seem to be getting alot of high CPU usage warnings. gonna try a reboot to see if it will fix, then rerun command

Did a reboot and reran the command. No CPU issues now, however already some files have moved into lost.dir. i have no experience writing/editing scripts. If anybody wants to write a quick script i could set to run on boot that would be appreciated.

Actually someome earlier mentioned to throw that into the loadpreinstall.sh under /system/bin
But there seems to be a caveat. If you plug the phone in through USB when the phone gets unplugged the device will get re-mounted. I'd like to change the properties of the internal mount instead of overwriting it each time. I have done a lot of checking around and found the vold.fstab file but don't really know how it works.
Another point of interest, what kind of MicroSD card are you using? I've got a Lexar 32GB SDHC10 card installed.

Lexar 16GB 4.
Do I just put
Busybox mount -o remount,ro /mnt/sdcard-ext
At the end of the script?
Sent from my rooted xt860

So this may be completely unrelated, but I ran the command Sunday, and my CPU went nuts. Rebooted tried again and all was good. Didn't use my phone much that day. Today(Monday) my phone died in 4 hours! I did notice my CPU seemed busier than normal. Did a bit of twitter websurfing then my phone went in my pocket for use as a music player. I use my phone with headphones everyday for music for 4-5 hours and I still have at least 30-40 battery left. Only got 3 hours of music. Now, is it possible that my music player(poweramp) is trying to write to the card, or someother app/system process is trying to write to the card, and since it can't it keeps trying. Is there a log I can pull on adb to figure this out? Has anyone else tried this and experienced anything similar?
Sorry for the ramble but I wanna get this figured out

[Q] Cant mount /SDCARD in recovery droid 3

I don't know if I'm an idiot or what but I can't find any answers.
I used the bootstrap from the market and got the success popup and when I boot into recovery it says error mounting sdcard.
I can mount everything else though.
Should I just be using safestrap?
I'm also using the vzw droid 3 and all that.
everything seems like 2+2 until this point
EDIT:
Just tried safestrap with the same outcome following all the normal precedures.
But backup just launched under internal sdcard, I don't need a external to flash right?
I feel like a Fck noob

To a noob
make shure the sd card is not corupt. plug it into a usb reader(not the phone, throu the usb, it will screw the phone up). then right click on the device when it pops up on my computer. click format. format as a FAT32 or else... then put the software back on. hope this helps.

Its the internal sd card on the droid 3. I'm about to see if I can flash. heres to hoping

How'd it go? Thinking of rooting my droid too.. Had it for 5 days not liking the bloat
Sent from my DROID3

Everything went fine. You dont need to be able to mount the sd card in safestrap from the mount menu.
Bootstrap was comming up with an error about mounting it and not letting me backup, so switch to safestrap if anyone else runs into this problem.

Thats whatsup
