[Q] "SD Card mounted as read-only"?

Hi,
I'm posting this issue second time. I have a class 2 SD card with almost 1700mb of ext3 partition. the problem is that my SD turns to read only when accessing some files from my sd card. it says in the notification SD card mounted as a read only and then say "tap" to resolve the card responded unexpectedly.
tapping on it sometimes help if i remove the files that I was trying to access that created the problem. otherwise it mounts it as read only.

Hi, you sure your card is a genuine one? The problems you are having are identical to what I had. Turns out my 32gb card was in fact an 8gb card, and the problem was when capacity was reached it would go to read only. The only way to rectify this was to take the card out, place it in my PC card reader right click on properties of the drive and run the error checking tool. Hope this helps. Got my money back anyway thought £36 was a bit cheap lol! Try writing a large file to the card using your Computer, this should give you an indication if the card is genuine or not.

Card is genuine. I have placed my card several times in my brothers htc hd and formatted it through windows. its almost 8 gb i checked it on windows. last time I deleted a folder which has wiered name as if the folder was corrupted. I deleted that folder n it was running fine again. but its back again.
mine came with telus, so it should be genuine. what does class signify? like i have class 2, what does it mean?

CLass is the speed of read and writes.
I recently had a problen like this it turned out to be a corrupt file in the .secure folder used for apps to sd.

then I guess its because of corrupt files but why is it so often specially when I copy something from windows.

I had this problem once after disconnecting from a Windows PC, simply connect the sd car directly to a computer and run the windows verification tool, it finds the corrupt file and your sd card starts working again

hey i recently had the same problem ,, but i figured it out and this method should work fine...!!
>First of all you should know how this problem has occurred..??,
well the reason is, we all connect the phone to system in usb mass storage mode ,,but while removing we'll only give safely remove in the system and forget to do the same in the phone ,,,trust me this the core for this problem....sd-card cannot be fully unmounted by system ,,, so you have to manually do this by your phone
so if you are using the sense rom ,,after ejecting the disk in the system ,,,in your your phone's notification area
in ''connect to pc'' menu select charging only .....this will completely unmount your memory card .
>if you are using non sense rom ,,"turn off the usb" mass storage
do this every time you connect your phone to the system ..!!!
ok now solution for your problem..
>reboot your phone to recovery mode using rom manager...
>select partition menu
>now select mount usb storage ,,,
>now you have tow options
1. either you backup every thing and format your sd-card (recommended)
or
2.mount your sd-card and check for errors in windows,,,
this should fix your problem ..
remember ,,next time when you are connecting your phone don't direly unplug the the cable..!!

The Class number represents a multiple of 1 MB/s
So if 2 is written on ur SD card then it means that its capable of a read speed of 3MB/s

- Not always true, its happened to me on several occassions when not connected to PC etc... Flickie HD caused mine
If you have a mac the fix is - disk utilities - repair card
Full format I found to be better though

[Q] My 16gb card shows as 1gb after a crash in a middle of partitioning with gparted

Hello,
My rom(iNsertCoin) has crashed today for an unknown reason, and entered nonstop bootloops.
I have tried to reflash the iNsertcoin zip but it didnt work for some reason, also it told me it cant mount the sd-ext (I am using ra-desire 2.0.0).
I have turned the phone off, and when I returned home I put my A-Data 16gb Class 10 Microsd (which was bought from newegg, so it cant be fake) in my card reader, and I started to partition the card like this: 1gb ext4, 300mb ext4, 100mb linux-swap, rest to fat32.
all of a sudden the program just crashed and from that point it tells me the card has 1gb unallocated space, in windows 7 it keeps asking me to format the card but it never succeeds, and it says the card uses raw file system.
I have tried chkdsk, and it told me its not available for raw filesystems.
I have also tried a number of programs, the HP partition tool, SDFormatter, nothing really helped.
Also, I tried using diskpart -> clean all command on the card but it keeps giving me weird error messages but usually it tells me its not ready, and it looks like the card is not responsive, although the pc recongized it.
I have tried doing this from a number of computers, another W7 computer and a XP computer. nothing worked.
I cant allocate space in gparted, and it tells me to create a partition table, and when I try that, the program just hangs.
Oh yeah, and I tried to put the microsd card into an adapter and put it in my dad's dslr and tried to format it, but there was an error.
Have I killed my microsd card? :/

Are you using gparted through an ubuntu livecd? Maybe try using the disk utility (system > administration > disk utility) to format the card with a new MBR scheme.

I am having the exact problem. Have you come up with any solutions?

Well, no.
I have sent the card to a-data for repair service and they have sent me a new card.
Anyway, slow speeds in almost any data2sd / data2ext roms still occur, so last week i have given up and got me an iPhone 4 from my carrier.

Yeah, I couldn't believe I did that either, but I was really fed up messing around with the desire.

the same thing happend to me once, after trying to get it going(formated on sunday and needed the card) it all went straight to hell until i tried it in another cardreader on my mac and the card is still working with no problems=

Damaged SD Card

Hello,
Yesterday while downloading stuff, my phone suddenly sent me a notification that my SD card is broken. I can access everything in Recovery somehow. What I've tried :
- un-mounting & mounting again
- re-flashing
- factory reset
- format in recovery
And everything that I listed above failed. When I plug my card into PC it doesn't open. My whole window is not responding. I've tried mounting it on my older phones (Nokia 2730 & LG KP500), and only Nokia readed my card, but I couldn't do anything because it was password protected. Every possible password I had for my old SD card wasn't the right one. I've already googled but nothing mentioned before helped. When I formatted in recovery it only froze. When I switched ROMs to more "original" one, when I plugged my SD card it was automatically removed. Also my SD card is EMTEC 16 gb Class 4, and just in case I have my old 1 gb sd card lying around.

There is a possibility that your SD card is damaged..........one way of trying to cure it is to somehow try to make it work on your computer and Format it............or just try to format it on the phones that it works on

Going to try format on my old Nokia. But I was thinking, if I can get my SD card to work in Recovery, isn't there anyway to connect my phone to my PC and then try to format?
EDIT: Tried formatting on Nokia 2730 - it was failure. I couldn't because of the password.

In recovery, I should press mount usb right?

Yes

I did as you said and in Partition Wizard it showed me that the whole disk is used, file system was bad disk, and type was logical.
When I tried to format it said "Windows was unable to continue formating".

[Q]: Is there a way to format this SDcard?
[Q]: is there a way to change the setttings whereas pics, music ,etc, can be directly sent to the SDcard?
[Q]: how do i access the SDcard when it wont let me into the card or it shows it is unavailable?

Try to format the card in pc using an incompatible format like ntfs and then put it in the phone and then the phone should ask you if you want to format the card. If not try to go to settings and format manually.

dude. just format the sdcard using your pc in FAT16 format. you can also try fat32 but I don't know how it plays with android.
cheers!
PS: after you format it using the above method, it's good to take the sdcard out from your phone and then put it back. just to be on the safe side

well...tried FAT16 and no luck?
im getting very frustrated at the thought of a phone that doesnt even see a simple SDcard when my PC does?

Well it might be some hardware issue. The phone does not recognize that sd card is in right? Does the phone show something when you plug in the card while the phone is on?
Did you try to put in other card?

nothing shows up when putting the card into the phone while it is on, but it does state SDCARD REMOVED when pulling it out from the phone

May be the SD card have some defect. Insert some other SD card and see if the phone nose it out.

ill probably end up doing that and just buy a new sdcard but i have a feeling itll do he same thing seeing as my PC sees it just fine and my last phone used it without a glitch. Now formatting this card for this phone, ive lost 1gb of photos!

Well I just did a small test. I have formatted a spare SD card with NTFS(I used MiniTool Partition Wizard for that) and put it in the phone. It told me that the SD card is blank and not properly formatted and asked if I want to format the card.
So this is something that your phone should do too. So my conclusion is that there must be either something wrong with the card or with the phone. So hurry to try a different SD card and if it doesn't work you should ask for replacement device.

thanks everyone so very much for all your help!!!
i called Future Shop (where i purchased my device) and explained everything including your guys help to them, and they said it sounds like the devices card reader is defective. So...seeing as i just got this on Friday last week, i can exchange it for a new device at no cost.
:good:

just got back in from future shop....
seems it was the sdcard that was defective but...
after coming home, i reformatted the old sdcard back to ntfs and dropped a pic on it from my PC and it still works?? lol
for some odd reason the device just didnt see the card? maybe cuz it was generic? maybe cuz it was only 1gb? i dunno??
however...got me a new 8gb sdcard for 14.00, thatll do me just fine!!
again, thanks for all the help

[Q] Micro SD card HELP!!

Ok So i have 2 micro sd cards one 8GB and one 32GB. I had recently just bought the 32GB one to give myself a good amount of space but unfortunately they both just stopped working all together. Basically one day my GS3 just began rejecting my 32GB card so i attempted to format it on my computer with a usb adapter, i tried both windows and mac os trying a range of programs but it just won't format. I even tried to format it using CWM but it can't mount it. but i don't think its fried because i just got it and it was working fine for like 2 - 3 weeks...so then i put my 8GB card in for 2 days and same thing...can't format or erase or mount on android...i've searched all over the web and need help cuz at this point i feel like my phone is destroying SD cards.

Yeah, this happens to me too. Reboot, let the phone say the card is damaged, open the back case while the phone is on, remove and re-insert sdcard and that should solve your problems.

If you are using windows try using the Command prompt. You will need to select the volume of the sd cards then delete it. I beleive they will become as RAW disks where you will have create them as new disks from disk management.

Open up an admin command prompt, then type 'diskpart' it'll start the utilitiy in command prompt. Then type 'list volume' it'll show volumes 0 through ~8 or so depending on how many you have. Once you know the number that is associated with your sdcard volume, then type 'select volume x' x being the number of your volume. Then type 'delete volume'
After that go into disk management and find your sdcard. It'll say unallocated. Right mouse click and create new simple volume.

Download the SD Card Formatter and try to format your card using that tool; see if that works. I made the mistake of formatting my brand-new SanDisk 64GB microSD card, which worked perfectlyin my Galaxy S III prior to that, and it wouldn't work afterwards. I tried all different methods of formatting & formatting programs to no avail. As soon as I used this program, my card worked like a charm in my phone again!
Good luck!
Dennis

Ive tried that and many other formatting programs but none of them work
