Deleting Partition?

How do I do this? I wanna wipe everything and make a new partition with a different amt of swap, etc. How do I go about doing this?

go to recovery and re particion your sd card. but remember to back up stuff to your pc that are important.

Follow these steps. I do them every single time before flashing a ROM, never have any issues that others have because they are lazy and refuse to just start fresh. I'm going to make this as basic as possible just to make it easy. It looks long, but I can seriously do this in under 3 minutes now.
You can either remove everything off your SD card and transfer on later, or leave it. It depends on if you want to resize your fat32 partition.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
If you don't have Amon_RA's recover get it Here
Boot into recovery (power on phone by pressing home button and power button)
Once in recovery, select (Go to console)
Press Enter
at the /# type this in
parted /dev/block/mmcblk0
Press Enter
When this pops up (parted), type in print
Press Enter
You should now see something like this:
Code:
Model: ([B][COLOR="Red"]whatever model your SD is[/COLOR][/B])
Disk /dev/block/mmcblk0: ([B][COLOR="Red"]the size of your SD card (write this # down for reference)[/COLOR][/B])
Sector Size (logical/physical): ([B][COLOR="Red"]Sector size[/COLOR][/B])
Partition Table: msdos
Number Start End Size Type File system Flags
1 512B 7405MB 7405MB primary fat32 lba
2 7405MB 7905MB 500MB primary ext2
3 7905MB 8001MB 96.0MB primary linux-swap(v1)
This gives you a break down of how much space is allocated for each partition.
The start/end/size values will differ depending on the size of your SD card and partitions.
Write down the size of your sd card, you can find it above next to:
Disk /dev/block/mmcblk0: ####MB
From here you can now delete and resize your partitions.
Number:
1 - fat32 partition (where you store music, photos, etc.)
2 - ext partition (where apps2sd goes)
3 - swap partition (used for swap)
Before you start deleting, make sure if you do want to remove the fat32 partition, you mount your SD and copy everything to your PC or wherever so you can transfer back later.
To remove individual partitions, type in at the (parted)
rm 1 Enter (this will delete your fat32 partition)
rm 2 Enter (this will delete your ext partition)
rm 3 Enter (this will delete your linux-swap partition)
Depending on what you deleted, you can type print Enter, again and it will refresh the partitions.
Using the number you wrote down which is the size of your SD card, you can figure out how you want to allocate the partitions.
I will show you what I type in and you can go off of that.
I have a 8GB SD card. 8169MB total
7405MB - fat32
500MB - ext2
96MB - swap
I only use 8001MB just to be safe. (not sure if it matters)
You just don't want to go over your SD card size.
Now to create the partitions.
The sizes below are my settings.
You can decide the sizes for you own SD card.
--------------------------------------------------------------------------------
For fat32 type in at the (parted):
mkpartfs primary fat32 0 7405 press Enter
This will create a 7405MB fat32 partition
--------------------------------------------------------------------------------
For ext2 type in at the (parted):
mkpartfs primary ext2 7405 7905 press Enter
This will create a 500MB ext2 partition
--------------------------------------------------------------------------------
For swap partition type in at the (parted):
mkpartfs primary linux-swap 7905 8001 press Enter
This will create a 96MB swap partition (you can upgrade to ext3 and ext 4 through the recovery)
--------------------------------------------------------------------------------
Notice the numbers I entered in 0 7405 (since 0-7405 = 7405, that's the size of the partition. Yes elementary, but just so you know what the numbers represent)
7405 7905 (7905-7405 = 500, 500MB partition, and so on)
You can choose whatever you want for the sizes of the partition doing it this way. Just make sure fat32 partition starts with 0, you want fat32 partition first, ext 2nd, and swap 3rd.
Once you have created the partitions, reboot into recovery and flash your rom.
To reboot into recovery, type quit at the (parted)
Then reboot recovery at the / #
It may look hard, but it is really simple.
Good luck.

I just made this so you can do the same steps from your phone.

[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!

you use "partiton manger" to repart your sd card

What do you mean? Is that a question?

Partition SD size

I'm using CM 7.2 and I finally decide to partition my sd card.
I wanna ask how big I should create those partitions. I have 16gb sd card class 2
fat 32 size?
ext3/4 size?
swap size?
and which order I should create?
thx in advice

You can create them from cwm simply without problems
sdext 1GB
swap 64MB

Order is important?
for example fat32 partition 0, ext3 partition 1 and swap partition 2?

No, go in cwm, advanced, partitions sdcard.
cwm will make all. try to go in cwm so can you see the options
if you want use a different software like minitool partition, you can creat 3 partitions all primary partitions:
1) sdcard in fat32
2) sdext in ext3 or ext4
3) swap

I've partitioned my sd to 512ext but never reach 200mb used..
Sent from public phone using 10cents.

16gb? so big memory for me
Ext 512mb and swap 64mb are enough for apps I thinks that...

Ext4 is better than Ext3, so if you can use gparted live (or minitools) to create the Ext4

hi,
u can keep 512-1 gb as ex3 partition. u can use cwm. its better and simple.
and hey a question? u r having 16 gb ? i tried with 8gb and my phone hanged like anything.. how u managee 16gb ??/

I do nothing to manage 16gb, all works fine. I only set cache sd to 2mb

you re welcome buddy

Read this about how to partition your sd-card
http://yagyagaire.blogspot.com/2011/09/how-to-partition-sd-card-and-install.html
Also, Since you have 16 GB sdcard memory, best sizes should be 1-2 GB sd-ext, remaining FAT32, no swap.

[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.

Fire droid bro n alfs8a
Help me please

alfs suport ext 2/3/4
check with a partition tool the sd,must be
Fat 32: primary(above 1024mb)
ext2/3/4: primary(max 1024mb)
and if you have swap: logical
For better results reformat your ext2 to ext3,backup your sd card first
I have a 16gb sd and 1024mb ext3 primary partition and it work
25 apps installed some of them in internal and my free internal space is 201 mbs
No need link2sd apk just move each app in settings/manage applications/to sd and automatically they moved to ext partition

Can't sent to ext(i have ext2)
I already test it

backup your sd card to a pc folder and repartition to fat32 primary and second primary ext3 512 or 1024mb
or you can also partition your sd via CWMrecovery
All actions it will format the card so BeCareful
