【Urgent】SD card become read only under android

Urgent!!!
I don't know if this is a bug or not. I used to copy files by selecting the disk drive mode. After that I will safely remove the device under windows before disconnecting the usb cable.
The problem is sometimes after copying files to sdcard, the SD card will become read only under android. For example I cannot copy or create files using file explorer. When using camera app it says "Unable to save file to SD card due to insufficient file permissions". When using album it says "SD card unmounted or not present".
After the problem occurs I cannot access the SD card via disk drive mode anymore, unless I physically removed and reinsert back the SD card.
The strange thing is I can still access the SD card in PC via card reader with no problem. I can also view the existing files in the SD card under android (eg opening .apk in SD card)
I tried flashing the ROM for 2 times and with a different SD card. Also I formatted the SD using Panasonic SD formatter and partitioned properly. The problem still appear after several access under disk drive mode. Million thanks!!!

I've noticed the same thing in the DL DesireZ v3.3 nand ROM...
But now since I've switched to skink_Clean_Desire_v1.0 I don't have the problem any more...
No problem solver I know... but just to confirm the issue!
It was also read-only when I had disk drive mode chosen and connected to my win xp pc!
so when I deleted files over the computer they still existed...
I always remove the sd card securely!...
hope this helps a little bit!

Memory cards get weak after awhile...Had d same issue with a Memory card...it works well on WinMo but messes up just as u described in android after a format n a few read & writes...Froyo has also been reported to ruin memory cards...Summary, there's no real solution as i've googled all over....My advice is for you 2 get a new memory card, capacity & class (d higher d number, d better its read & write speed) is up to you...I'm using a class (4) 8GB card n its been alright.
P.S. Stop transferring files via d disk drive option in android..stick to using memory card readers or d MAGDLR function (though some also report file errors with dis).

Thanks for your reply
But how come windows and wm can read and write normally but it doesn't work in android?
Also, I have been using NAND and its disk drive option to transfer file in Cotulla's desire stock Rom and there is no problem at all. Would the problem be related to app2sd since the card has a ext4 partition?

do a chkdsk on your micro-sd card. let it repair and then don't delete the LOST folder in your sd card. ^^ you will be able to mount as read/write after this

Try a chkdsk as well...But in my experience, i did it several times & it only acted as a band-aid...As it reverts to read only ltr on...

So is this a SD card problem or ROM problem?
Previously I had been using Cotulla Desire stock Rom for a month and the problem didn't exist.
I don't mind buying a new SD card if it can completely solve the problem. Thanks

[Q] Rooting without internal SD

Hi,
I got a Galaxy Y from a friend and I was trying to MOD it. I discovered that the internal SD is not available... and no way to get it back. I tried to wipe data, hard reset, stock firmware upload with ODIN but no way to get the internal SD back. I tried ADB in order to try to push the ZIP files in a ROM folder but of course no permissions as it's not rooted.
So, no way to root my mobile without copying the files to the SD?
Thanks in advance
Joe

I dont know what you mean by internal sd - galaxy y 5360/6102 doesnt have internal sd - it uses a mico sd card to which you will find the slot if you take the cover off and look on the right hand side of the phone
place any files you want on the sd card either via card reader or usb cable
please note that questions should be asked in the question and answer section and NOT the general section

Thanks Marcus,
I did not know the mobile had no internal SD.
That's the kind of information that saves a lots of time and work!
Thanks again.

Ok,
I tried to use a Miscro SD on the GT-S5360 but there was no way to have it acccepted by the phone.
I formatted the Micro SD (Sandisk 2G) in many ways (full formatting) and it was mounted OK with all my other phones (Galaxy S, LG L5II, Huawei) but not for the Galaxy Y. I tried to format the card with the other Samsung too but it did not work..
I've read a lot around about the "blank SD" issue on many mobiles and tried some of the suggested tricks but with no luck.
So, assuming there is no way to have a MicroSD installed on the phone, I resume the original question:
- Is there any way to root the GT-S5630 without an SD card?
Thanks in advance
Joe

well unless your sd card slot is damaged there should be no reason why it shouldnt work
the sd card needs to be formatted in fat32
there best way to do it is to inset your sd card into your phone
goto phone settings
storage
unmount sd card (sd must be unmounted before you can format it)
format sd card
you can also format it via your pc using a card reader as long as its fat32 but its best to format it using the phone or format it again using the phone as sometimes cwm may have problems mounting the sd card if you use something else to format it
You might find universal root tools via google but the quickest most simple way is just to use a root zip file and flash it in recovery or cwm

Thanks Marcus, your replies are very quick .
I tried formatting the SD card FAT32 with different Allocation unit sizes, always full formatting, never quick.
The SD card is recognized as BLANK SD CARD (or unsupported filesystem) when inserted with the phone ON. The same occurs when I switch ON the phone with the SD card alredy inserted. The card is never mounted
The internal formatting functionality of the phone seems to be not working at all. The function FORMAT SD CARD is enabled but when launched it lasts just few seconds and nothing happens (the card is not mounted neither automatically nor by hand).
There could be some compatibility issues between the card and the phone and it could be worth to buy another SD to test the phone card reader again, but I'm not confident it will work.

allocation unit size is I think 16 kilobytes but just select default - quick format is fine if the card is not damaged
you can try using mini tool to delete the partition on the sd card and create a new one and format it to fat32
you can then try reformatting it on your phone after

Thanks for your help Marcus,
I tried MiniTool, with both FAT and FAT32 (the card is a 2GB card) but the result is still the same: BLANK SD CARD.
I will try to buy a new one tomorrow and see if it makes any difference...
Thanks again

Ok I got a new MicroSD today and everything seems to work fine.
Thanks again Marcus.

well did your SD Card get partitioned.??
And it may not support CM11.
I will surely get back to you on this.

It did get two partitions.
Maybe problem is that I put primary one in NTFS and second one in FAT 32?

Well you should not partition it as NTFS.

Micro SD Card formatting issue

Hi,
I want to format a micro sd card initially formatted with the and used on my Axon 7. Using the smartphone "application", the sd card disappears when it reaches the 20%. If I try to remove the sd from the smartphone and format with my computer (I try with gparted on ubuntu and with build-in + EaseUs window applications), my computer returns an error (impossible to complete the operation, etc.).
Anyway, the micro SD works correctly. I can read, write, and delete files on it without any problem.
Did the same thing happen to you too? Have you a solution?

You sure you can write to all of it? SD cards become read-only after a bunch of write ops. Hapoened to me on 2 SD cards already. When you try to format it, it'll just return an error or stall somewhere

SD card for app storage

I'm using a 400GB SD card. I saw a comment about creating 2 different partitions on it as I want to use part of it for app storage and the other part for file storage, The second partition would be exFAT so I can remove the card and transfer my books, music, etc. to it by attaching the SD card to my laptop as I understand that Windows would not be able to recognize the partition that would be formatted as internal storage. I did format the SD card using my laptop as two separate partitions. My Samsung Galaxy Tab A saw both partitions. I selected the 96GB partition as I wanted to use that for app storage and selected the option to use it as internal storage. Unfortunately when I did that, it appears that the system set the whole CD card up for internal storage. Does anyone have any insight on how to accomplish this - use part of the SD card for internal storage and part of it for storage that would be recognizable by Windows? Thank you very much.

I have not tried, so take the advice as a suggestion, perhaps android can be "fooled", which I doubt.
After creating a bulk partition in android, move the SD to Windows and resize that partition, and create a second partition on the remaining capacity and hide it.
Now move the SD back to android and see what happens.
If android will reformat the partitions again then I can't advise anything else.
However, if android accepts the memory, then the next step is to discover the partition in Windows and recheck the SD in android.

Well, I was trying to work on that and now the Android Storage module (in Settings) keeps crashing when I open it. IDK what happened here. I've reformatted the SD card, I've removed the SD card, I've rebooted the table multiple times. I'm almost to the point of having to restore the tablet from scratch ... again.

Try this:

Complete app management, move to SD, clear cache, remove bloatware and more

You're trying to convert a partition in sd card as internal storage and leave the rest as an external storage. Not possible as far as I know.

Thats a bummer but that is what I was feeling was going to be the outcome. I guess I'll just go with it as internal storage then and be rlefated to wireless transfer of my books, etc. To the tablet. Any thoughts on why my Storage module keeps crashing now? Something definitely went nuts somewhere along the way here. It was running fine.. until I start poking around with this. I'll probably just do a rebuild again tonight.. if I can find my steps notes.

I also don't think it's possible to do what you have in mind. It's also important to remember that Windows will only mount the first partition of an SD card. It won't see any other partitions without 3rd party software installed.

The reason people want a micro SD card is to be able to move it around between devices, so it is not a good idea to convert it into 'internal storage' for two reasons:
1. You can no longer move the card around (not without reformatting it again).
2. This process would significantly slow down the system if the OS starts saving apps, data and files on the micro SD card because it sees this space as internal storage.
Because of how you partitioned the SD card and tried converting only a part of it as internal storage, my guess is the process caused corruption somewhere, and the system is crashing because of that. I'm afraid you'll have to do a factory reset and start from scratch. I hope your files are safe.

You should NEVER use an SD card for internal storage. They are MUCH to slow for that purpose. Today's SoC have RAM chips mounted directly on top and are several times faster than the fastest SD card bus. And low end tablets, which includes ALL Tab A devices, use a USB bus with limited bandwidth. So using faster SD cards is pointless as they will still only be as fast as the bus. SD cards are fine for storing video, audio, text and downloaded files, but NOT for running apps. Doing so will cause the device to be laggy at best, and cause crashes at worst.

Something strange in that attachment. Since when do Android SD cards have NTFS partitions? As far as I know, the internal storage partitions that Windows couldn't read were formated as Ext3 or Ext4 and the external as either FAT32 or exFAT.

Don't suggest the volume label. Partition K: is FAT. The example shows that Windows can show two partitions on a USB stick.

Of course it can. It can show several. But NOT the two partitions created on an Android SD card because one of then is formated in a file system Windows doesn't recognize and that is what the poster was talking about.
edit: Disk Manager will actually show the partition but it won't be assigned a drive letter because Windows can't mount it.
