[Q] Ext3 on 16gb SD Card

Hello.
I have bought a new SD Card (kingston 16gb Class4).
I had a lot of problems with ext3 make. By Gparted it have errors.
I have readed this topic.
Can I repair my SD Card?
Sry for my english.

How are you connecting the card? Via a card reader or still in the phone? If it's still in the phone make sure you are in recovery and not booted in to android.

I made it by card reader. Formatting and partitioning by recovery - errors.

Have you tried erasing all the partitions and creating them again? What happens if you click the 'Repair' button?
I've always done my partitioning with my card in the phone, connected to my PC while in recovery and used Minitool Partition Wizard for Windows (this software was suggested in a thread I read a while ago) and never had any problems.
There is also the possibility of the card having a hardware problem, so you might need to swap it under warranty.

yes, first i have erased all partitions (deleted)
On repair ext - error, fat32 works fine.

first make an extended partition for your fat32 and inside that a primary fat32.
The unallocated space make it ext3

shouldn't both partitions be primary (no extended ones)?

erase everything 1st keep it unformatted then create fat32 primary then ext primary (optional linuxs swap) this is what i have done when installed miui rom data2ext

i suggest you dont use that card reader try through the cell....

I have tried a lot of methods - ext still no works.

Where did you get the card from?
Stupid question but two of my friends bought cheap (fake) cards from eBay and both had problems with them, either the card kept losing data or they go errors loading from the card due to the poor quality. In which case you need to spend a little more and get a proper card from amazon on a high street retailer.
If not then as suggested use try formatting and partitioning the card through the recovery on your phone, most of the up-to-date recoveries can do this and it's the easiest way to get the card ass needed for a2sd etc. if it still doesn't work then take the card back it's probably faulty.

I bought this card too and even though I had no issues formatting the card I do have speed issues with it. I've been in contact with Kingston and they're looking into it. My writing speed is 1.6Mb/s....
But now a tip for you, I couldn't use Gparted since it's Live CD wont start my monitors. So I downloaded Easeus Partition Master. Very easy to use and it worked perfect.
Start with your Fat32 partition and then your Ext partition.

SDCard 16GB - Gparted / Phone show 12GB

So.. i was installing RCMixHD Rom yesterday, i partitioned my card as follows (using Gparted in Ubuntu):
FAT32 14GB
EXT2 2GB
This Rom is awfully bad, it crashed few times and freezed that i couldnt even reboot so i had to remove battery when it was still running.
I decided going back to CM7 but i just realised that SD Card size is 12.84GB, and Gparted doesnt show any partitions on it, what the heck?

Use a card reader or connect the sd while in recovery and make sure all the partitions get mounted.
If android is booted the ext partition doesn't get mounted. Also if you created your ext partition while android was booted that probably messed up the ext partition and that's why the rom doesn't work right.

First of all a 16 GB cars is more likely 15 Gb in real life.
Moreover, the phone does not recognizes the ext partiton in the SD card menu (in settings), just the FAT32 one.
So 15GB-2GB-possibly some unpartitioned for data = 12.84 GB
That's OK.

Thanks, i think it's fixed now i got 14.8GB of space available again.

Is that a class 10 card? i am trying to figure out which card should i get for my desire, after bad experience with kingston 16gb class 10.

Its Class 4 Sandisk SD card.

if you want to partition the card try ext 3 for a2sd+
Minitool Partition manager is the way to go to create ext partitions on a sd card
free too..

[Q] PC cannot read SD card when mounted as hard disk drive, WTF?

Hey guys,
Once I was living happily with Starburst ROM Lite 1.3.0 and Data2SD (flashable ZIP of Sibere's script) with Dalvik2NAND on a 1280Mb Ext4 partition on my 8GB class 4 Kingston microSD card. However I found that a 1280Mb Ext4 was too much of a waste cuz' all that I needed was 400Mb at most, so I repartitioned the card with Amon-RA Desire and set Ext4 as 512Mb and FAT32 using the rest. Then I flashed the ROM and the script again. At the begining everything was okay. However, recently I've found that when I connect my phone to PC and select the connection type as Hard Disk, the PC can recognize a new hard disk, but tells me that it is not formatted. I checked the partition status in Paragon Hard Disk Manager, and to my surprise, it CAN recognize the FAT partition and its free space and so on; also, the FAT partition can be read and written normally with Android apps like Estrongs, Astro and RE, even in recovery.
Yesterday I reflashed everything and the situation remained the same. I wonder, what is the problem?
P.S. this situation appears not only on one computers, but many.
Many thanks!

Partition(s) may have messed up. Format your SD card so it's all a FAT32 partition and see if that works. If it does work, just repartition it again with ext4 and FAT32 and see what happens. These things happen.

My arc cannot recognize formatted SD cards, help?

I've tested two sandisk class 4 SD cards.
If I format it to fat32 and partition the space(to use link2SD), my phone refuses to use the SD card and says it's not there. I use minitools for partition and the official SD card maker software for formating. I did everything by the book and tried multiple options(different labels, ntfs, ext2, etc.)
A fresh, unallocated space card works perfectly fine however.
My phone is rooted and unlocked bootloader running softMIUI rom with a modfied power saving blend kernel.
Please help! This is confusing the hell out of me.

Was looking at your post and I decided to grab a few of my MicroSD card 1gb, 2gb, 4gb, 8gb and 16gb....
I formated all of them on windows .... right click format, all default settings... Fat32. These are MicroSD cards that have had information on them... they all run fin on my arc. All different brands.
This leads me to believe that there's possibly either something wrong with the MsD card or the reader on the phone.

Solved it
Did this:
Changed the partition id to this:
"0*06 fat16,greater than 32 mb"
and made the second partition fat32 as well.
Removed the 100mb linux swap file partition I created....not sure if that was necessary.

Memory card frozen!!

Hello, I am using a Sony Class 10 32GB micro sd card in my android mobile. I have partitioned the SD Card into 3 parts. And recently I faced a problem that my memory card froze and I couldn't delete or move any files. Also I couldn't format it. I have scanned my device if any virus was there but there isn't any. I used many different tools such as Minitool Partition Wizard, Easeus Partition Tool, HDD Low Level format tool, and also GPARTED and windows disk management.
But none worked. All the files are as it they were and even I can access them. I dont think it is a burnt card also there is no physical write lock switch as it is a micro sd card.
Please help!!!
