[Q] can I format micro sd ext4? - Fascinate Q&A, Help & Troubleshooting

I have ParanoidAndroid [CM10] rom, with devil kernel atm [I may go back to stock, not sure yet], and I keep losing data with my micro sd card [files get dumped with random number as filename into LOST.DIR/] I suspect it happened this time cuz it was full and an app tried to write a large file to the sdcard
Can I format my micro sd as ext4? will it still mount ok?

I don't know if it will work. I've always formatted my flash cards with sd formatter, you might try it to see if it fixes your problems. I usually use full (overwrite) and turn on format size adjustment under options.

No I know how to format the card (I have Linux), I'm just asking whether cm10 will say "sdcard needs to be formatted" ? Or will it just mount it like normal.
Thought I'd ask before I tried because if I can't, it would save a lot of time formatting, and copying/pasting my files.

if you format it FAT 32 with sd formatter CM10 will recognise your card (tested), should work if you format it ext4

[Q] Screwed up sd and more

I just created a ext3 partition for my sd and it got screwed the phone couldnt recognise it said it has corrupted. ended up formatting it through phone now my firmwares screwed cant mount sd, keeps rebooting and not able to use the notification bar (TRIPMIUI mod by cf) now im reflashing my FW throuugh SEUS. Lost all my contacts and messages. Can somebody tell me where did i go wrong to cause this landslide of BULL?
- formatting sd should go first Fat32 then the remaining space go to ext2/ext3..
- both should be formatted in primary. The phone need to read the fat32, those ext2/ext3 are for the system link which only work after the phone boot up normally.
- Full backup is always a good way to prevent any unwanted landslide of fire...
I have the same issue. Partitioned my SD card and my phone could not find it after. I also tried to resize my fat32 partition with data on it along with a ext3 partition to see if it would find my sd card but had no luck making it work.

If you want to start over, reformat your SD card with this:
http://www.sdcard.org/consumers/formatter_3/
For some reason, some of the custom roms do not recognize the SD card after you've created partitions. Reformat and try again.
Even when I reformat my sd card the phone does not detect it. I believe that its because of my ext3 partition. seems like the phone reads the 2nd partition (ext3) as the main partition of the sd card.
Where does the android system determine which partition is the main one?
There must be some type of script that tells the system what partition to look for. Am I right?
If there is then maybe we could mod the script so it, always reads from a certain position first.
Anybody know anything about something like this?

Im running miui 1.7.15 and i get this msg on my status bar saying damaged sd card and then it recommends formatting which i did but nothing changed except I lost my pictures and music .... it happened after i used the super build.prop tweaks .... can someone please help me fix this, thank u in advance
Plug ur phone to a computer if it detects ur sd card format using windows utility if it dont detect then u should use third-party software like acronis disk director....it's not free but it has worked for me in the past..good luck

I had this happen to me before on cm7. I reformatted it in windows (not quick format but full) and it seemed to work. But a few days later I got the SD damaged alert again. After playing this game about 3 times I decided to try SD formatter 3.0 to wipe the card and then I just booted into recovery and formatted it (seeing as it was wiped clean already) and it worked like a charm. SD formatter is free so I'd suggest giving it a try.
Good luck!

When you get this message its actually referring to your external sd(emmc).Don't format because It'll format your internal sd card which really sucks if you apps and music, etc.Try opening your ex-sd (emmc)on root explorer on your phone if you can.There's corrupt info on it I'm almost sure and wipe file that the has time stamps from like the year 1969.If you can't then use a microSD adapter and use your computer.Hope this helps.

Eh, I had this happen and formatted..it did my external sd card not the internal.
I've also never used CM7 or any other GB rom so i think it might have something to do with the SD card read ahead scripts that most ROMs are using nowadays.

[Q] Formatted internal sd to ntfs

By pure accident I formatted the internal sd card on my atrix to ntfs. The problem is I cant seem to mount it in order to format it back to fat32. Any ideas?
How do you 'accidently' format the internal SD to ntfs???
How did I 'accidentally' format the internal sd card. Had an external sd card in, which for some reason was named to mot as well. Wasn't paying to much attention and wanted to format the external one to ntfs but must have clicked on the internal one.
That sucks d00d. If it was the external card - you could use a card reader and your PC to reformat.... Idk what to tell ya about the internal.... Maybe someone who's done this and fixed it could chip in with some info here? I did a quick search on it, and didnt turn up with anything... Sorry I can't help ya man.
Connect your phone to your PC, and format the card to fat32 the same way you did it to NTFS.

I tried to do that, but the problem is it wont mount. It says sd card damaged you may have to reformat it. But when I click that it says "sd card has been removed"
Try using CWM recovery to format the internal sd card.

Try formatting sd-ext or internal storage rather than /sdcard. Don't format anything like /osh, /data, /system, /cache etc.

Go to your device forum. People there are more likely to know and help you on how to solve your problem. The solution I will give is a Atrix only solution. I believe samsung has a software of the name "odin" but you have to check with the people in your phone forum.

Maybe you can try flashing a SBF. Make sure you know what you are doing, and flash the full one, some SBF leaves your internal SD untouched.

As a rule of the thumb please don't use CWW for partitioning your sd card as it cause errors. Try a tool called minitool. Use it to repartition your sd card with your card reader and computer. Then format it to FAT 32 file system. Hope it works for you !

The official organizaction that designates the SD card standards has a tool for formatting SD cards called SD Formatter which can be found here https://www.sdcard.org/downloads/formatter_3/. Make sure select the full format option.

Maybe there is hidden corrupted partition and some programs cannot see it. In recovery I can't mount sd ext. Maybe problems are with this partition?

Another suggestion would be to try using the gparted disk partitioning utility if you have linux you can download it from here gparted.sourceforge.net/download.php or use a live CD/USB version of it http://gparted.sourceforge.net/livecd.php.

As long as you just reformat the SD card and not any of your other hard drive partitions it will not harm your computer.

Make sure under the bios setup options you have CD as first boot device rather then the hard drive this should allow you to boot the gparted live CD.

There is at least a loss of 800 MB. Using mini tool see if there are unused space. Try these steps:
1) First of all delete all the entire existing partitions .
2) Then create a single partition .
3) Perform a full low level format using FAT 32 file system.
4) See if this works otherwise your sd card has got bad sectors which might be unrecoverable even using scandisk

External SD card permission issue

Weird enough suddenly I found all my external SDCard files have all permissions like:
---rwxr-x
Why !?? This happens to every file I copy onto it.
I needed them like:
rwxrwxr-x
so far, the only rough and long way I found is through Aromafilemanager and PhilzTouch recovery.
Yet I have to change the permissions one file at a time.
Can anybody help?
Sounds like a problem unique to you, I've never heard of it.
Flash the official stock rom, format your sd card in your pc using the industry formatting tool and test.
If the problem disappears then it was probably some combination of your individual setup.
Yep. Also ensure you haven't got any scripts running at startup. Sd permissions are set on boot and cannot be changed afterwards

Any mods that mount folders or swap storage.
Otherwise, something built into the rom.

which filesystem do i have to use in formatting extsdcard 8gb via pc? exFAT / FAT32 / EXT4 / NTFS ?
moreover, in this post and following on dev rom thread, it seems it's a normal behaviour... am i missing sth?
https://www.sdcard.org/downloads/formatter_4
Fat32 is the normal filesytem.
If it's common to your rom then your chef is the best one to approach, he may have set a script or mod.

I read through about 7 pages of sd card issues on the s3 and thought i cant read anymore, so i thought i would just ask. I've just bought an s3 and i got my 64gb sd card from my old phone to my new one. Problem is i have data from other games in the SD and titanium back up files in the externel sd card. Seems the S3 has its own built in SD card and only reads from that. I copied my TB files from externel to the internel. Now the games still require Extra files although they are in the externel SD. So how in the world do i get it to read my Externel sd instead of my internel? I thought of copying the files but i have 16 gb internel, 64 externel so its not gonna work considering i have 39 gb left in my 64 gb one,
