[Q] I can't partition the sd card

when I put the card into a card reader, the sd card can't be read, only can be format. But after I pressed format, it said it can't. What happen to my card? but if i connect my phone to computer, it can show all the files in the sd card.
The important question is that, I have rooted it, and i want to use app2sd. If i can't partition the sd card with ext2, i can't move apps to sd card. I have tried to use rom manager to partition it, but still can't. Any method other than buy a new card? thx~~
You need to flash amonRA's recovery.
Just do a search on the forum as there are a couple of how to's.
From there you can partition your card, verify your ext partition, upgrade from ext 2 to 3 and ext 3 to 4.
Good luck.
sometimes that can occur with a bad card reader. have seen it many times. the card reader will read some cards but not others.

[Q] Help with SD card error!

Hi!
I formatted my SD card to use with A2SD earlier today in GParted, but I forgot to format the rest of the card to FAT32. Now my SD card says ReadOnly and I can't find the card on my computer...
Should I use a card reader or what should I do?
Thanks alot in advance!
By computer, do you mean your Windows, or in gParted?

[Q] formatting SD card

Atfer i format my sd card by the computer , the partitions will have gone and i'll need to creat them again?
there are directions how to do that?
tnx very much!
You shouldn't need to create partitions on the SD card after you format it. In fact, you can format it from the phone too. >Settings >SD & Phone Storage >Unmount SD Card >Format SD Card

Click to collapse
the problem is that i cant choose "Format SD Card".
Only "Unmount SD card"..
Do as I said. You have to unmount before you can format.

[Q] Deletion of EXT4 Folder on SD Card

Hello,
I have a 16gb SD card that I am trying to format. It has an EXT4 folder on it that I cannot delete. I cannot write to the SD Card as it is showing as in use.
I have a back up for my Desire but it is on my PC, therefore I cannot write this to the SD card. I can only access the SD card through my PC as when it is in the phone it will not mount.
Could someone explain how to delete the EXT4 folder so that I can write to the SD card? At the moment I have no Mobile!
Many thanks,
Simon

I guess you mean that you have an ext4 partition (formating normally doesn't care about folders).
I would suggest formatting the sd-card with an sd reader outside of your phone.
An alternative would be re-formatting your sd via recovery if you have clockwork mod installed. (or e.g. via adb: http://forum.xda-developers.com/showthread.php?t=534714)
OK, managed to delete the file through EXT4 Recovery and mounted to my PC. Thankd for the help by the way!

Formated SD card through TWRP Recovery

I have a small problem
I formated my internal SD card using twrp and now it only thinks that it has only 2 GB on the SD card (but it really has 16gb)
Because of that I can't make any backups, is there any fix or I wasn't supposed to format the SD through recovery?
It seems formating the SD card through the phones format setting worked
