Hey guys
I have Samsung Galaxy S GT-i9003, and I am using the vold.fstab mod for swapping the internal Sd card for the external. I have every thing running fine. But I noticed a strange problem. When I open applications, it seems like the memory card gets mounted in read-only mode, as when I try to use any file explorer to remove files, it cannot delete until I either use root explorer with mounting as R/W mode, or rebooting the device. If so, things get fixed, but after some use, the problem recurs. Besides, I noticed that while the problem is active, the gallary opens empty with a message showing up "No SD card detected". Otherwise, and even with the problem is active, apps open normally and flawlessly, but unable to write files or delete them. Rebooting always fixes the problem.
Any idea why this is happening?
BTW, the card is very new and healthy, and opens perfectly with card reader on windows, and sends and receives files to and from the computer very fast, and it is 16 GB.
Thank you
I solved that problem after months of research... You see, the problem is corruption... The explanation is very very complicated so I am giving you the things you need to do to fix that read only problem...
(Should be done by steps)
1. Put your sdcard in a card reader (recommended) and use chkdsk /r (if you are using windows)... Or simply go to drive properties and go to error checking, check all the boxes and start scanning until finish... Put your card back to the phone... Check if the problem still persisit... If it still persist, do step 2...
2. Backup all files to your computer... Reboot your phone to recovery mode and use the format sdcard option in the mount and storage menu... Restore all data afterwards.. If it still persist, do step 3..
3. Believe it or not, some files in your sdcard are causing a data corruption (This was my issue).. The only fix for this is to find out what files are corrupted... Mostly, the directory that contains these files are from:
sdcard/Android/
sdcard/Gameloft/
sdcard/data/
sdcard/lost.dir/
Do step 2 first... When attempting to restore the files back to your sdcard, do not include this directories... This will more likely solve your problem...
4. Some tweaks such as sdcard speed tweak and other sdcard related tweaks in init.d folder is causing this problem... Try to boot your phone without them and see if it works....
Thank you very much.
I really have some gameloft games installed and believe it or not, the problem is almost always occurring when I open these games !!
I will try your solution and inform you of the results .
BTW, what if the problem is caused by the files of these games? And what if the problem recurred after restoring these files? Is there a permanent fix for that?
Thank you

It seems like it's SD card problem, although it's new!!
I was playing on a game installed on USB Storage, and all of a sudden the game became unresponsive. I then forced reboot the device, and when restarted, SD became unavailable!! I went to "SD and storage" settings and both SD card and USB storage give "Unavailable". Pressing on "Mount SD card" does not work! Formatting is not working!!
Any suggestions guys??

BTW, I remind you that I am using the vold.fstab mod, gingerbread version. I tried to install another SD from my friend's phone that is working fine in his AT&T Galaxy S i9000, but once done, it gives me "USB Storage damaged" !!!!!!!

Seems like I lost my SD card
It opens normally in Windows, and I could back it up. When I delete all files, it gives that they were deleted. But when I eject it and reinsert it, the files are not removed
Neither formatting nor chkdsk in Windows work
GParted gives "Unable to open /dev/... as read-write (file system read-only)"
Any suggestions??

do you mind to post a screen short by command mount in adb shell?
Actually, I took the memory card back to the reseller, and they changed it for another working one. I just dont know why would all of this happen! The card is new, but there were problems preceding its damage, like the aforementioned problem of read-only!!

It seems that I forgot to mention regarding a bad sdcard.. Some issues are appearing because your card is either damaged or is badly made... Glad to hear your problem solved...

Actually, during searching for a solution for my problem, some websites suggested the following:
1- if your card gives you that it is read only, try to use micro SD adapter, and put the lock half way between the locking position and the unlocking one, th en try to perform chkdsk, followed by formatting attempt.
2- if formatting has failed, try to use GParted (bootable live disk is available online and can be downloaded).
Your internal SD will subsequently be recovered once the external is recovered, or simply, put a new external SD of whatever size, and you will regain access to your internal SD, and thats supposing you are using vold.fstab mod
Please let us know of the results , hopefully it works with you

Hello,
Internal SD-card (USB-Storage) won't automatically mount itself when Android starts. It only mounts my external SD-Card. In CWM i can access everything (internal sd, external sd, system etc.) i can format them also. when i connect my phone to the pc i can read and write to both SD-Cards. Everything seems fine, but when android boots (with my ext sd inserted), i enter my pin, and my homescreen appears. Everything is ok but only my external sd is mounted, not my internal (USB-Storage). But when i boot without the external-sd inserted it mounts my internal-sd without problems. Weird. When i insert my ext-sd (phone is running) after my int-sd got mounted, it also mounts my ext-sd. What´s the reason for this behavior? Does anybody know how to fix it? can´t be a format (rfs/ext4 or FAT like) problem i think, but maybe i am wrong.
My Phone is:
Samsung Galaxy S i9000 running
CyanogenMod 10.1 / cm-10.1-20130111-NIGHTLY-galaxysmtd.zip (Stock CM-Kernel, also used semaphore jb 1.9.3)
Maybe someone has an idea how to fix this problem. I´d really appreciate any help.
Greetings,
Strainhunter
fixes, i think^^
I think i fixed the problem.
I copied all the files on my external sd (yes, the problem with the internal sd (usb-storage not mounting was the external sd )
then i formated emmc in CWM--rebooted--> and the copied the files back to the ext-sd. Till now i rebooted the device multiple times and both sd´s are mounting fine^^
Thanks to me^^
Greetings, Strainhunter
Update: Problem came back -> got fixed
Hello Again,
After recently the problem came back, i experimented a little and found out that the problem did go away when i made my nandroid backups in tar format, but came back when i made them i dup format. I think it was the big "blobs"-folder on my ext-sd that caused it.
Just wanted to update this thread, because if someone encountered this problem too, he maybe want to have a look at his Nandoid-backup-format.

Hi, I was wondering if anyone could help me finding a way of mounting /storage/usbdisk/ as sdcard.
I am using CyanogenMod 11 Nightly.
The problem is, the usb disk works almost ideally - Reads audio and video from it with no problem, but when I want to move
obb/data or other app data ( iGO navigation ) to it, it just doesn't read it.
I tried this solution
but I was wondering if it is possible to mount whole usbdisk as sd card, like the phones with SD Card slot do.
I tried mounting /storage/usbdisk/ to /storage/sdcard/ and /storage/sdcard1/ and /storage/emulated/1/
none of those helped.
Thanks in advance.

Firstly when you go in settings storage/ ad scroll down with your usb storage plugged in does it show the free space on that device n the storage settings? if yes
all you need is the pro version of foldermount
Apk is on playstore forum support/ user guide for it is just a xda search away
Im using it on the experience rom for the moto g x1032 8 gig sngle sim version.
ive so far tested asphalt 8 which is about 2 gigs of data once installed. I created a android folder on my usb storage and withing the android folder i created a data and a /obb folder
i then linked those folders.......youll get what im saying when you go to the foldermount thread here on xda.
Hi Experts,

Please help me to solve this issue.

Hello,
I own a mtk phone, a Wiko Rainbow (Wiko -- a french low cost phone brand) and I recently got a quite awfuling problem: the sdcard is no more recognized afetr having been formatted The sdcard of the phone was no more recognized on any PC for some time. So I decided to format it so this issue be fixed. Then I did.
But now, the phone doesn't recognized the sdcard at all. No way to see it in phone browser. the sdacrd doesn't appear in Settings> memory too. I tried many kind of formatting : fast formatting, or not with Windows 8.1, I also delete the FAT 32 partition on sdcard, then recreate it in FAT32... No more success...
So I tried to access trough adb but no success...I get a strange error I've never seen when trying to cd to usual mouting point of sdcard (/mnt/sdcard1/) The error: Transport endpoint is not connected. Any idea so I recover my sdcard please ? that's really boring !
Thanks in advance
The phone has a stock recovery, is running android 4.4.2 KitKat, and is rooted.
[Edit] tested with an other Wiko Rainbow (which had some sdcard problem too) and same issue !! Exactly the same ! sdcard no more recognized with "Transport endpoint is not connected." issue trough adb ! I precise I used an other sdcard, but same brand that the first
So, to resume we have 2 phones Wiko Rainbow, 2 Samsung class 10 SDHC card, and exactly the same issue for the 2 devices ! Problem can't be software, because it's been updated some days ago for the both smartphones, and the problem didn't solve.
So I tend to think the samsung sdcard may be defective, due to too many R/W perhaps ? I have no idea.... Can somenone enlight me ?
Thanks in advance
Up please!
Problem not solved yet ! :crying:
Please help !
try using Mini Partition Tool. Format your sdcard from there.
Yes, it's what I did straight away, but doesn't work.... After formatting, sdcard is also rejected like if I had never formatted it and like if it was damaged....
i think your sdcard is corrupted. You need to buy a new one. (last option in my opinion)
Yes, it's what I envisaged at first. But how is it possible that a second SD card got the same problem?! Maybe it's the phone which corrupted the SD card?
