Hi all, I just used CW Recovery to make a 1gb extra partition but don't know which version ext it made. Can someone provide me with some code to write in my terminal to line up my sd-card partition. Thanks.

Afaik cwm makes ext2 by default, check with 'mount' from terminal, look for sd-ext and if will say ext2/3/4 next to it.
Thanks man.
It seems that the cvm provided in the [Nightly]CM7 thread made ext4 filesystem, atleast that's what I have but it could be the data2ext mod I flashed that converted the ext2 to ext4, I don't know.
More chance that the data2ext mod formated your partition with ext4

Is it possible for someone to create a script to convert ext3 to ext4 and backwards.
I'v flashed my recovery menu with unrevoked, and clockmodwork doesn't support ext partitions in their recovery image.

This recovery allows you to convert your ext3 partition to ext4 (not backwards)
But you can easily do it within Linux using GParted
I've tried that.
When i start gparted it indeed can let me format back to ext3, only when i format back to ext3 i will lose my data on the ext4 partition.
I thought maybe there was a option to create a GScript script, so i can run it on my phone.
Have you try to mount ext4 as ext3?
http://en.wikipedia.org/wiki/Ext4
The ext3 file system is partially forward compatible with ext4, that is, an ext4 filesystem can be mounted as an ext3 partition (using "ext3" as the filesystem type when mounting). However, if the ext4 partition uses extents (a major new feature of ext4), then the ability to mount the file system as ext3 is lost.

PULL the files from the ext4 partition, then format it to ext3 and PUSH them back.

i should had figured that out myself
i've created partitions using minitool partition as follows
FAT32-6.6gig , EXT-4 1gig , LINUX SWAP 39mb
when i've installed s2e(simple2ext) it didnt show ext partition so did freespace app ,so i've formatted sd-ext via clockwork mod ,now when ive connected my sd-card to pc i am seeing ext2 instead of ext4 & my linux swap is not being used by cyanogen mod nightly
type in terminal su(enter)
free (enter)
swap is being all shown zero's
how to solve these problems , & does cm7 support ext4,what is the correct partition method to get 1gig ext4
Try to change kernel. Default one doesnt support ext4
tapatalked from HTC wildfire
oh i thought cm7 supported sd-ext from the start , ill check & see which kernel supports sd-ext 4 thank you +1
arco68`s kernel on cm7 supports ext4
Can someone explain to me how it is possible to change the ROM format on the device from ext3 to ext4?
What is to do to have DesireHD running on ext4 instead of ext3? Just simply convert the format will not work...
Thanks in advance!
You mean partition, yes?
Either by flashing melethron's ext4 format .zip (ext4_alignment.zip)
Or partition the card with some partition program (GParted, Easeus etc.)
i guess he was talking about the internal partition of his desire HD..all his post are in the desire hd section, he wrong forum
Might be a stupid question.
Well here's the deal i partitioned my sd card to ext4 (i think i'm not sure how i can find it out if it is ext3 or ext4). I was reading that ext2 was faster and quite better than ext3 or ext4 so i was thinking is there any easy way to deconvert from ext4 to ext2. What is the best way to do this preferably without loosing any data from sd card or the partition?
And how can i find out easily what partition my sdcard is ext3 or ext4?
Im not sure where you get that information but devs wouldn't recommend EXT4 partition if its gonna slowdown the performance of their roms.
I bet gparted can tell what type of ext partition you have and I bet there are other ways to find out... You can flash 4Ext Recovery and that will show you those information as well.

4ext recovery converts partitions but only between ext3 and ext4 without data loss. Al though I am scratching my head, where did you read that ext2 is faster than others?
Ext4 has more features than Ext3 and Ext2, main advantage is journaling which gives improved performance and reliability. The only downside with ext4(also ext3) is that the SD Card wears out faster since it can perform more read/write activities. If I was you I would keep things the way they are.

I know but I believe it would be able to tell what type of Ext partition the sd card has

I saw something about it on androidforums.com and somewhere else i can't remember where.
There few people said that after going from ext2 to ext3-4 the rom that they had became a little laggy and it said also that some kernel dev said to use ext2 rather than ext3-4.
Also said the same thing you deadlyboss01 said about the sd card wearing out sooner.
Is it maybe silly to use ext2 if i already have ext4?
And if i set up 4ext recovery can i restore nand backups from cwm?

I believe it can since 4ext recovery is based on cwm but better post the question on the 4ext thread to get an accurate answer. Sorry im not that sure.

It seem that you are quite adamant. Have you personally experienced these lags?Also, I had the impression that kernel devs focused more on ext3/ext4. Nevermind, CWM is indeed compatible with 4ext recovery as Stankyou said.
No i personally have not had these lags but it seems that i'm just going to stick to 4ext and try to flash the 4ext recovery and check that out
Thanks to this thread(and others), i got some balls and knowledge. And i've installed, 4eXT Touch Recovery and then converted my ext3 partition to ext4 with 4eXT, way to easy. Needless to say, that Recovery is awesome! Thanks People! !
I also read this on ext2 being better and was confused, some guy had a htc incredible s and experienced lag with ext4 and not on ext2.
Well, i also see alot of devs using ext4 and now this thread... think this is quite simple, Use ext4 if the rom supports it.
Is there any major difference between an ext3 partition on one's sd card and an ext4 one? Is there any point in converting an ext3 to and ext4 (using 4ext recovery)?
Also, if I did this, can I restore a backup made from my old ext3 partition into an ext4?
Edit: This has been covered before, I only just spotted the suggested existing threads feature. Damned if I can find the way to delete this thread though.
