[Q] SD Card Mounted Readonly Problem

Hi,
I keep getting this error - Mounted Readonly.... the sd card has an unexpected problem.
I installed the NextSense 3.0 Rom earlier, it worked fine for a while until i installed some apps to the sd card and then this error kept appearing.
I searched for solutions and every one involved removing apps, especially task killer. I have removed everything and the problem persists. Does anyone know what the problem is?
Failing that i'm going to wipe everything and start again, can anyone tell me how to correctly wipe and repartition everything? The instructions I found to partition are:
"Partition SD" SWAP=0, EXT2=512, FAT32=<remaining>
then "SD:ext2 to ext3"
any advice would be great, thanks!

Not sure it's all that helpful, but I had the same problem with ieftm's Official 2.2 ROM. The problem seemed to go away after I connected via USB to my pc and selected the 'Disk Drive' option on selection type on my Desire. After I disconnected, all was good.

I had this problem also. So i just popped the card in my computer and reformatted it with Gparted (in linux). If you don't use linux, i'm sure you could still format it in windows to fat32, but then you'll need to create an ext partition via the phone.

thanks for the reply, thats what happened when the problem first occured. I had it connected as a disk drive to copy some apps to the sd card and after disconnecting it the error started.
i tried it all again nothing helps

grrr i hate taking it out of the silicon case, incase it goes all saggy.
thanks, i'll give that a try

I also had the problem when I tested ieftm 2.2 rom, I changed to another, using recovery to format and partition the SD card, and everything went back to normal.

Any suggestions... Tried adb shell mount /sdcard and everthing else I've found...

Like i suggesetd before. Take the card out of the phone and plug it into an sdcard reader and format it that way.

I had that issue with some of the OTA ROMs apart from Pinky.
Just connect it to pc in disk drive mode and then remove safely in windows and then select charge only and remove cable. should be fine.

I had the same problem and I repaired it with Windows Vista Tools. Right click in the drive letter, Properties, Tools and Check Disk.
It solved some problems and it worked fine in the phone.
Regards

I had to format my whole card, the Win7 repair function doesn't work for me...

based on my experience, this issue occurs if you don't do reboot after the first boot. so after you install the rom, when it asks you to set the language, reboot your phone again. after that then complete the setup process.

not true
This happened also to me with ieft ROM. I did a few reboots before this happens to me. I tried some workarounds that people say in this thread with no luck. When connecting the phone to the PC, phone did not give me the option to mount the sdcard like disk drive. In the end, I'm formatted sdcard, deleting ext3 partition.
I'm using ap2sd of Froyo with "Mod Install Location" app from market. And this works fine. I have no problems with space in internal memory.

the quickest way i solved this problem was to unmount the micro sd card under the SD & phone storage options then remount it again. thats how i solved it, hope it helps.

Sry, but this function is freezed, it doesn't work. At the moment only repartitioning is working for me. It seems that problem is because of Froyo implementation. Shame

oh well

better make a list of all possible ways to fix this prob i suppose, starting from easiest to hardest.

I have fixed this issue with the wipe of the dalvik cache! Try this!

I had the same issue. Copied everything across from the SD Card to a temp folder on my PC (Win 7 x64) then it came up with a copy error from one android.temp file, I skipped it, copied everything, formatted to FAT32 then copied everything back across and the issue was fixed.
Maybe something had locked that file and corrupted it perhaps?

This method worked for me too in Windows 7, was just wondering if it is a ROM problem or Froyo or APP. anyone could advise so we can avoid...?

When it happened to me it was a corrupted app. I had downloaded an app from a site and put it on my card. I don't think it downloaded all the way, and messed it up. But the way I fixed it was moving apps and formatting the card.

[Q] phone does not connect to PC via USB

[SOLVED] : using dropbox now for file transfer...
After I installed the latest build of stock XDAndriod on my Rhodium, it does not connect to my PC (win-XP) using USB port. I have tried multiple times to reset my phone and re-flash my winmo with no help.
My computer does not detect a USB device at all when I connect my phone when in Android. When I plug in my phone, nothing happens. But my phone does begin charging from the USB port and does detect that is plugged in to a power source.
How do I get my PC to recognize my phone?
Phone details:
H/w : standard AT&T tilt2
Winmo : JackOS build Aug/19
XDAndroid version - [MJG]Rhod.2.2Froyo.083010.rar
Thanks,
Dhanvi
PS: I did check the thread here - http://forum.xda-developers.com/showthread.php?t=641444&highlight=USB+problems and that hasn't solved my problem.

If you read the port status, USB data connections are not currently supported. Only charging is supported via USB.

Thanks for that pience of info, but I do not see anything saying USB on the project development page. Is there some other page that I should be looking at too?
If that is indeed the case, then how do I transfer stuff over from my PC to my SD card when in andriod ? Is there any other method?
Thanks.

Great Idea but waiting for more help
Hey Fist post here about the xAndroid. I have to say this rocks!! First time I got it up I said to myself this is how a phone is supposed to run.
To the questions do any of you know if this USB connection is going to be fixed anytime soon sine I would really like to see if you can connect Google App Inventor to the phone while on this great mod.
Thanks

By far the simplest way to get it done.
I went for installing ADB and droid explorer on my pc. It works, but I have much less hair now.

with the current way xdandroid is built, I can't see it being probable that usb mode will ever work (could be wrong, so feel free to correct me).
i.e. currently we have a FAT partition on the SD card and we loopback mount files on it to act as the android system and data file systems, and the fat can then act as a normal SD card.
because of this, it can't expose the FAT partition to anyone outside of the OS instance (i.e. 2 OS's will be writing to the FAT table (redundant I know) independently and can clobber each other.
On the other hand, I think the way the cyanogenmod port works, by partitioning the SD card into multiple partitions to hold the different sets of data (though not sure it takes it all the way), is an approach that could be made to work for usb access, if separate partitions would be made for the system and data file systems on the SD card and a third partition just used for the FAT FS. This way, android can unmount the FAT partition only (nothing else depending on it) and let it be accessed by whatever machine the device is attached to over usb.
there's a reason its not done this way currently as its much harder to manage and continuously update.
just my 2 cents.

Hm, does this also mean, you can not use tools like MyPhoneExplorer (Outlloksync via UBS with Android phones) due to absence of data over USB? Seems like a decent app, but it does not see my TYTN over USB, says no conenction. I also note, Windows XP is trying to install an 'Android Phone' driver when I connect the TYTN to the Laptop. Is this all somehow related?

Oddly, my phone decides to turn on USB after it's been sitting plugged in for a time, which exceeds an hour. It's like it checks for USB connectivity at some long interval.

With Android on my wife's HD2 (booting from Windows via Haret.exe) USB mass storage mode works fine, so it's definitely doable.

No clue how - when you're in WinMo, what happens when you plug in your phone and select to use it as a disk drive? It unmounts the SD in WinMo and mounts it on your PC. Same thing would happen in Android, but when the card can't be unmounted - as Android is running off of it.

I've been told it's flaky on the HD2 and not recommended for use anyways. Still not sure how it works tho.
We won't have true SD card access (USB mass storage) until Android is flashed onto our devices. Until then, true USB mass storage will NOT work.
In the meantime, there's ADB. Perhaps the HD2 guys hacked something up based on ADB, who knows.

[Q] computer not recognizing evo as a disk drive

Hey everyone first time poster here. I have been researching the question I have in the forums and have not found an answer to my question yet so I figured I would just ask it. I just recently bought my htc evo and tried transferring a SNES rom over to my evo from my PC. At first my computer would not recognize that I was trying to have my evo seen as a disk drive (yes I did have it set to disk drive and not to charge only or another option). eventually it worked (I dont even know what I did, if I did anything at all). After I put this ROM onto my phone my sd card is mounted as read only (cant get it back to write), and no matter what I do I cant get my computer to read my phone as a disk drive. I tried changing the disk drive to another letter which didnt work, under device manager my computer recognizes I have an android phone plugged into my computer, but it still will not show anything in the "my computer" folder, it sees I have a device in, but I click on it and it says "please insert a disk into removable disk F". If anyone can help with this I would greatly appreciate it and thank you for taking the time to read all of this.

Well the first thing to make sure of is that after plugging in the device you go to the notification bar and press on the USB Mass Storage notification, then select "Turn on USB storage". If you've done that simple step and it still doesn't see the SD card, then very simply try a different USB port on your computer.
Even if your card is in read only mode, you should still be able to read it
I don't know why it would be in read only unless you forgot to mount it with read/write after an advanced command.

interesting, I have never seen the option of "turn on mass USB storage" when I've gone to the notification bar? In my notification bar I have a picture of the sd card with a question mark over it. When I drop down the notification bar the notification pertaining to the sd card says "mounted readonly" and the explaination says "The SD card has an unexpected problem. Tapping...." I have no idea what it says after that as it wont allow me to view the rest of the explanation.
As for the problem that this is causing is that it seems I cannot save anything to the sd card. The camera stops working to where I cant take pictures, or download music, and I'm assuming that its because these functions need somewhere to save the files and since the card is on read only nothing will be allowed to save on it?

theres probably an error on the sd card, may need to reformat if its from a different phone too. Try to reformat, probably the only thing possible right now. But before you do that, go to your settings and enable usb debugging and see if that works first to allow your sd card to mount to the pc. Then it should be read as a drive. if not, your gonna have to reformat. so try this, if not, I can try to trouble shoot you more......

thanks for your reply. And yes I shouldve said before that I tried the USB debugging feature as well and that didn't do the job either. I saw reformatting as a suggestion in another thread but didnt see information on how to do it and that is out of my realm of knowledge. If you could explain to me how to do it I would greatly appreciate it.

yea, no problem man, just go to settings>sdcard/sd>unmount the volume>reformat!
let me know if that works for you if not, something else is wrong.

well I go into settings> SD phone & storage> Unmount SD card, is something supposed to happen or am I supposed to do something else? After I tap that nothing happens and the "format SD card" option isnt highlighted meaning its not even an option to choose.

Hmmm. Unmount then remount then umonint again turn the phone off and on see if the uloption highligjts

oh wow that worked man!! Thank you so much for your help, you just saved me a bunch of frustration, now it shows up as a disk drive on my computer and the sd card is read/write compatible. Can't thank you enough man, do you happen to know of a reason as to why this would happen? I mustve set it to be like that somehow I just can't imagine how I did that. Also is there an app or way to back up all your files and apps on your phone and sd card and transfer them to your computer just in case something like this happens again at least I'll have backups so I wont loose everything.

Glad i could hel you. Ita no problem that you cant thank me enough, just as long as we solvee tue prob. You Could have dropped your phone and it knocked the SD card around or it just didn't read it correctly on boot. As far as I know, I don't know of any apps to backup SD card contents and phone data. I would just make a nandroid backup and store on PC. So if you make any vital errors, u can restore using your recovery agent.

[Q] Dropped my phone - Now stuck in bootscreen

Hello guys,
I woke up too early this morning, and i accidentally knocked my phone off the stairs. It fell about 2 meters, bounced and then fell another meter, bounced and fell another meter and stopped.
Thankfully it was in a silicon case (i think that's what made it bounce) and there are no visible damages.
I picked it up, and it seemed to be working. After a few secs it went into sleep mode and would not wake up.
I removed the battery and rebooted, and i got the HTC screen, then the nexus boot screen and it stays stuck on the nexus boot.
I then entered recovery mode and thought i would try and restore my backup. I get the following message:
E: Can't mount /dev/block/mmcblk0p1 (or /dev/block/mmcblk0)
(No such file or directory)
E: Can't mount /sdcard
I took off the SD card, put it my pc and it works just fine.
I got another SD card, copied a rom onto it and tried to reinstall through recovery.
I did a wipe/data factory reset and tried to install the rom.
I got the same message...
Is my Desire toast? It's only six months old...
I was running Defrost6.1 and using psfMod 0.9.7.2 as my recovery.
Any advice would be extremely appreciated.
Thanks
aalex
UPDATE
I did another wipe data / factory reset, and i rebooted.
The rom starts up, without any of my previous settings of course, but I still cannot mount my SD card.
From file manager, it seems that it is being mounted, but no files are listed...
When i try with gallery it reports "SD card unmounted or not present".
Any insights?

With your SD card in your phone go into settings then storage and unmount SD card. Then format your SD card from your phones menu and it should mount the SD card see if that worked.

Hi ste1164,
Thanks for responding. My problem is that my phone cannot pickup the existence of an SD card.

This is a typical USB-brick. I've had one a few weeks ago. You should look at this thread: http://forum.xda-developers.com/showthread.php?t=691639&highlight=usb+brick.
If you're new to this, it can be hard to get it working again. Just let me know if you have any problems. It took me a few hours to get it done

From fastboot via ADB, execute "fastboot oem enableqxdm 0" and then reboot it with "fastboot reboot" command.
See if it works.
If you don't remember how to do the above, just search.

its not a usb brick, thats a software brick.... it sounds to me like you have a corrupt sd card, sd cards are very delecate and this can happen from a sudden impact, try formatting the card in windows explorer, obviously you cannot format your sd-ext using windows so try gparted or ubuntu to format your other partition.

Can't be sdcard, op said tried sdcard in PC and tried different sdcard...same result, must be sdcard reader or something.
You never know, might be a USB brick, just happened before the drop and was brought on by the reset...but I agree probably is hardware fault.
Is it possible to flash stock rom from fastboot without sdcard? Could try warranty repair then...

sorry i didnt notice that, could be a usb brick but like i said thats S/W related and i doubt dropping your phone could cause such an error, +1 suppose the sudden reset could cause the usb brick especially if the device was reading or writing to the sd card when it happened, could also be the sd card reader in the device has been damaged or one of the internal components. can the device read the sim card? if it dosent, could be a usb brick

Just a thought...is the sdcard reader attached by a ribbon? (never seen the inside of my desire, hope I never have to)
I'm sure I've heard of a few desires that can't read sdcard anymore, I reckon it's either attached by ribbon or it's the most delicate part of the phone.
I'm hoping it's a loose ribbon because that's an easy fix, even I could do that.

Hey guys,
Thanks to all of you for responding.
My sim card works just fine. I can make and receive calls, texts, go online via 3g and Wifi, connect through bluetooth. As far as i can tell, my phone does everythind it did before except mount an SD card. Also, the android market keeps crashing, and if i try and download anything from the net i get a prompt saying that i need an sd card to download.
So far I took the SD card and put it in my pc. I formated it, tried again but it didnt work.
I then tried a brand new sd card and that didn't work either.
However, I did not format the old card's ext2 partition, and the new sd doesn't have an ext partition yet.
Would this point to a USB Brick as mentioned above?
Would it be possible for me to flash the stock rom on the device?
Thanks once again, to all of you.

Yes, that should solve your problem. I had the same problem a few weeks ago, but that included a malfunctioning usb, even charging didn't work correctly.
To fix the sd-card, you should run the above command using the tool fastboot, available in the Android sdk. After downloading, cd to the tools folder in the sdk and then run the command while your phone is connected to your pc in fastboot mode. Then it should work again.

Hey koenvbeek,
Thanks for the help. I think i may need a bit more of it
Here is what i did so far:
I used Nephrons guide to download and install ADB.
I then rebooted to bootloader. The phone displays "fastboot" and then when i plug it in it dispalys fastboot-usb
I then went to the ADB tools directory and tried to run the command.
I got a message saying the command cannot be run because adbwinapi.dll is missing from my system, and asking me to reinstall everything...
Clearly i made a mistake somewhere but where?

I don't think you made a mistake
Either the requested file is missing, or it can't be used by your computer. First check if the file is present. If not, google for it.
If it is present, your computer can't use it for some reason. Are you on a 64-bit OS? If you're on Vista/7: did you open the cmd promt as admin?

Yeah, nothing wrong, it's just that the API library is missing.
Download it from the attachment here, and put it in the "tools" folder, then try again.
Edit: As you can see it's in an archive, since dll attachment is not enabled here, so extract the file from it.

Another GParted Issue with the Desire

I stuck the phone in usb debug mode and ran gparted live. It said no partitions though the stock fat32 is there, fair enough, so I created two, fat32 about 15gb and ext3 512mb, mib aligned.
I rebooted into Linux and when mounting the drives on the phone they come up and I copy files across as normal.
When I unplug the phone Android doesn't see them, the stats say double the data I copied over has been used up but none of these files are shown/available. Instead all I see is the "lost and android" folders. These folders are also not shown when mounting the drive.
It would appear android is not seeing the drives correctly. Any ideas?

Always better to format the card away from the phone using a card reader and an adapter

Agreed. You should NOT be trying to partition your SD card by simply plugging in your phone and enabling disk drive mode...

Yup that worked. I was following a dumb guide on youtube for the Desire that doesn't work.
Cheers, Andrew
