[Q] Memory card damaged coz of making partition!

I decide to install one of android builds from this section on my X1,It's CWM needed,so I have make 4 partition on my card[ 1Fat 32 & 3 EX2]using MiniTool Partition Wizard Home Edition 5.2 and then apply.....My device doesn't detect the card anymore,just asking for formatting and I hit yes,and It appears again and again,trying to format the card using MiniTool Partition Wizard again to NTFS,Fat 32 and FAT again,no results,Unformat mark appears on the partition on this app.
I also tried HP format tool,but it doesn't help too....
PS:maybe it's better to ask it in X1 section,But I prefer to ask it here Bcoz of visiting by more peoples,sry....

Did you partitioned your first partition with FAT32 format? Windows can only detect the SD card first partition.

Yeah....
But just to know if i have did it what should I do?

maybe you can use "partiton manger" to repart your sd card

It's not the problem with partition software because I'm using the same version with Reza.
Did you done all the partition exactly the same as below?
Format SDcard To 4 Partitions :
- 1st partition: FAT32 (SDcard / Rest)
- 2nd partition: EXT2 (System / about 150 MB )
- 3rd partition: EXT2 (Data / about 250 MB)
- 4th partition: EXT2 (Cache / about 100 MB)
* Make sure all partitions are set to PRIMARY

Hi guys, I partitioned my sd card on my android froyo smartphone but after the process was done the phone hasn't recognized the card any more and nor I can see it thru the computer. I don't have a micro sd card reader but I assume that's gonna be my best bet...
Please let me know if you have any hint.
Thanks in advance

I got hold of an sd reader and the card is perfectly seen by the computer. Of course windows won't see the ext2 partition but under minitool partition wizard both partitions are shown.
I wonder why my cellphone is not recognizing the sd card then...
Hope you guys can help.
Thanks again

the first partition must be fat32
right: FAT 32 | Ext2 | Ext2
wrong: Ext2 | Ext2 | FAT 32
Check that every partition is set to PRIMARY

That's what I did. As soon as I create the second partition the phone won't see the sd card.
I'm gonna try a different program and see if maybe it goes better. Do you have any suggestion other than minitool partition wizard?
Thanks again

Tried with gparted but always getting the same problem... still stuck...

Can you believe I created two ext partitions, one ext2 and one ext3 other than the first fat and the phone is finally recognizing the sd? That is so weird... but working!

[Q] Ext4 Partition issues?

I want to install RunnymedeMod and it requires that I have a 1GB Ext4 partition. I have an 8GB SD Card...
I use Minitool Partition to create a 1GB Ext4. I apply the changes... I take the ROM zip file and put it on my SD card. When I go to the Recovery to install it, I go to chose the Zip file and it isn't there...
I boot my phone back up and open my SD card's file on my PC. When I look, the partition is no longer there and the ROM zip isn't on my SD anymore... it is getting frustrating.
Any helpful ideas?

The reason you can't see the 1GB partition is because Windows cannot read ext partitions. I suggest you install 4ext recovery, then create an ext2 partition and then upgrade it to ext3 and the lastly ext4. This is your best bet to make sure it's partitioned correctly and smoothly.

So I have touch 4Ext Recovery... when I want to create partitions it says First Ext and Second Ext and then Swap size.
I have an 8GB SD and I need a 1GB Ext4 partition.

First ext: 1gb, skip second ext and skip swap. Then upgrade to ext3 and lastly ext4.

[Q] Swap Area / EXT2 partitions - Help needed.

Hello, I'm hoping someone can answer a few questions I have regarding the format of the SD Card for the Android system. - Apologies if this has already been explained on this forum, I did a search but didn't find anything too useful that answered my questions.
(I have knowledge of the linux file-system and swap drives, just unsure of the benifits of this for android).
Currently using a 16GB SanDisk Class4 SD Card.
I'm aware that you can format the SD Card to use as a swap-drive and for use of ext2 file-system.
While searching for info on this I found the following xda link which simply explains how to do this:
http://forum.xda-developers.com/wiki/SD_card_partitioning
My questions are:
1. What are the benifits of having the ext2 file-system? (Would apps stored on SD Card run faster etc?)
2. Do I need to keep a FAT32 partition (as opposed to just having a swap and ext2 partitions without any FAT partition).
3. Does the swap drive greatly improve performance. And is this worth doing on a Class4 SD Card?
Thanks in advance!

Hi.
at the first I must say swat will decrease SD card life.
i recommond you to create EXT3 or EXT4 partition.
1)one of the benefit of EXT partition is your phone storage will not full and its help your phone performance.
2)yes.of course you should have fat32 partition for eg:music-movies...and other files.
3)yes.swap is a very good.and it helps your phone ram.eg:when you play plants vs zombie at the first screen game will exit because of ram and swap will use like ram and its good for gaming.

Thanks for the reply, much apprecaited.
Are you sure I need a FAT32 partition though? Videos, music etc etc can all be saved to ext2/3/4 on a linux OS so I just assumed I could just do away with FAT32 all together?
Is the following just not the same as using an App2SD app?
"1)one of the benefit of EXT partition is your phone storage will not full and its help your phone performance."
Sorry for being a bit fussy but I'd like to fully understand what the Ext/2/3/4 partition is actually used for. Is it just used purely for storage?
Thanks again!

In a short summary (and assuming you are using a Kernel and ROM supporting the features) ...
- "Swap" on a swap partition has its own own "filesystem". The data structures are actually created by "mkswap" and the partition is not directly accessible by the user. If your phone runs low on physical memory unused parts of the memory will be swapped out into the virtual memory to make room for other apps.
Note that this is no "magically increase your RAM" solution. Once swapping occurs it actually slows down the system as the swapped out memory regions need to be copied back into physical memory, sooner or later. It may only help to run "RAM hungry" applications.
- "SD-Ext" is a, most likely, ext2 formatted partition to where Apps you move to the SD (either by Android or App2SD) will go. This increases the amount of apps you can possibly install, but doesn't resolve the problem that apps having widgets or apps that are started during Android boot-up need to reside in the internal phone memory.
- The /sdcard partition where all your user data is being stored should be kept FAT32 (for the simple reason of making a backup of your data by slapping the card into card reader easier - Windows can't read Linux filesystems by default). Some ROMs will allow you to format /sdcard ext3 or ext4 ... the advantage is that ext3/4 (if the mount options are correctly set) may perform a lot better than FAT32, though your mileage may vary.
Roger? ...or do is something still unclear?

Many thanks B.Jay - I'll hit the thanks button after I post this reply! You cleared up all my questions, but just going back to the FAT32 partition;
I use linux as my main OS, so accessing the EXT format partition wouldn't be a problem; Do you know if all ROMs would work without a FAT32 partition and replace it with EXT2/3/4 partition? If you're unsure I can always find out by formatting and loading a rom.
Thanks again, you've been most helpful!

Linux would, of course, be able to mount a ext partition (even on a SD card put into a card reader).
As for the ROM ... it depends.
The Stock Kernel Modules AddOn of GingerDX introduces ext3 and ext4 modules for the SEMC Stock Kernel, so in theory (I didn't test it!) you should be able to access /sdcard when being formatted ext3/4 - though it could be that you might need to adjust the vold script to properly mount the partition. The modules are mainly for supporting the sd-ext partition for "Apps-to-ext3/4-partition-on-mSD".
There's also alfsamsung's Alfs Kernel which is compatible with GingerDX and some other ROMs. That would be something you could try as well.
Simply look through the ROM threads ... I think MiniCM7 (+nAa's Kernel) should be able to support it, though this could involve some tinkering.
Personally speaking, I only have a ~2GB sd-ext on the SD in my X8 and the rest is a normal FAT32 partition (/sdcard).

yes you need a FAT32 partition.
when you partition your SD card you can move moveable app and games to ext partition.
please dont move app wich they cant move to ext partition.
cause after restart app that you moved to ext will corrupted.
good luck.

Thanks again! I think I'll follow your trend and try the 2GB SD-ext and the rest FAT32.

sd-ext missing!!
hey guys!! I've a small prob, would appreciate some tips. I normally move apps to sd card, if the app is movable by default. if the app is not movable by default, i use this app2sd by droidsail (available in the market) which force moves parts of the app 2 sd card. When I make back ups using xrecovery, i have no problem.
but when I use cwm for back ups, it gives an error saying sd-ext not found and it skips that part of the back up!! so any app I've moved by default or forced moved to sd card doesn't get backed up!! So I presume I have to create a sd-ext partition manually? How do I do it? I do have an sd-ext folder. but its not in sd card. it's in the root. (never had this prob with xrecovery though)
thanks in advance!!

As with every storage media you can actually partition the mSD. By default it ships as a single partition that is FAT32 formatted (otherwise Microsoft couldn't play Mafia and press license fees out of Android phone manufacturers as the FAT file format is copyrighted by Microsoft).

You can partition the mSD in either ClockworkMod recovery or you can turn off your phone, take the mSD out of the phone and put it into a card reader and then partition the card on your computer by i.e. EASEUS Partition Manager (Windows) or gparted (Linux).

I don't know how you usually check if your hoe is working (oh how I love typos), but you can check if the SD card partitions are working this way:
- Boot the phone
- Once it's booted up and you have no warning about the SD card then the partition mounted at /mnt/sdcard works. To check if /mnt/sd-ext is also working either open the "Terminal", type "su" (without the quotes) followed by "mount" which will return all currently mounted devices.

If you create a sd-ext partition (USE SEARCH to know what this means!) you can move your apps out of the internal phone memory onto the sdcard (this actually even works without a designated sd-ext partition). However, you can't move each and every app to the SD ... apps coming with widgets, apps that start automatically upon boot, a widget or a live wallpaper can't be moved to the SD as it will stop working.
Swap on the SD (to have virtual memory - much like the "pagefile.sys" of Windows or the swap partition of Linux) only decreases the lifespan of your SD most likely considerably when there's a whole lotta swapping going on - apart from needing a custom kernel as the Stock doesn't support swap.

A Class 4 mSD isn't blazing fast, but it should be about sufficient. In general, the higher the number of the Class, the faster the card, the more fluid the I/O transfers.

Look into the "Advanced settings" menu - and note that not each version of CWM contains that functionality. CWM 4.0.1.5 that is in some thread around here does not have the partitioning capabilities, CWM 3.2.0.0 (as shipped with GingerDX) is able to perform it, CWM 5.x.x.x as in nAa's or Alfs' custom kernel is up to your for checking out.

Depends on what you want to do ...
- swap and a normal data partition
Create a ~256-512MB swap partition
Partition the rest as a FAT32 partition
- sd-ext and a normal data partition
Create a ~1GB ext3 or ext4 PRIMARY partition and name it "sd-ext" (w/o quotes)
Partition the rest as a FAT32 partition
- swap and sd-ext and normal data partition
Create a ~256-512MB swap partition
Create a ~1GB ext3 or ext4 PRIMARY partition and name it "sd-ext" (w/o quotes)
Partition the rest as a FAT32 partition
And ... this information could also be found by using the Forum search!

AM WELL AWARE ABOUT THE SEARCH.BUTTON! !!!
well if you read the 1st post .. I have mentioned clearly that I am noob at android.
All I want is a brief explanation on partition ..
I read some were swap ain't supported on stock kernel and I an on stock kernel ....
Do I need a computer to partition? ??? please explain the process briefly......

Help with SD Card

I tried to make a EXT4 partition on my SD card to use it for A2SD. I used MiniTool Partition Wizard, it went well. But after I restarted the phone, nor the MiniTool Partition Wizard, nor the Windows Disk Management can't see the EXT4 partition. I just lost ~200MB of space from my 2GB card. Is there a way to repair this or can I think about buying a new SD card?
Also, in CWM recovery everything associated with EXT partitions gives me errors.
ROM: Prime HD 5.0
Kernel: nAa-11
-------------------
L.E.:
Problem solved. Partition SD in the advanced menu of recovery.

Try running these commands in the terminal (the EXT partition will be formated):
Code:
su
a2sd formatext
If you get an error, you will need to use GParted (a Linux partition tool) to create correctly the EXT partition.
EDIT: Gparted also can recover your "lost space" if you wish.
