Rephrase your question better.
Are you asking if it is good to have EXT4? Then yes is the answer
I think yes. But yee, I just see in recovery when flashing a rom saying formatting that and that ext4 nand. Then I was wtf ok hope all works. Now I restored back a nacho from cm reaper all works kinda. Some tips mby, I'm new about android first android. So its better?? What a difference. I just want to look on 100 post

Ext4 uses a filesystem performance technique called allocate-on-flush, also known as delayed allocation. It consists of delaying block allocation until the data is going to be written to the disk, unlike some other file systems, which may allocate the necessary blocks before that step. This improves performance and reduces fragmentation by improving block allocation decisions based on the actual file size.
In other words ext is better and makes your phone faster.

did the same, formatted in ext4 all partitions, all's working very well, ext4 is an update from ext3
Deem I flashed 4ext recovery and I notice I have system ext4 data ext3 catch ext2 SD fat 32. All Is ok not good.

Use 4EXT Recovery to convert your file systems to ext4, from my understanding ext4 is backwardly compatible.........
I tryed that and I did get that log when emmc chip fried, tested with command to test it, emmc is ok but my catch partition is corrupted I think, and when I go recovery I see cant mount cache/recovery/command
I get scared out of hell I flashed Eng hboot. Some tips what to do next??

Restart into Recovery.
Then format or wipe your cache partition.....this should do no harm to your device and will not loose any data.
I'd then ensure that it's ext4 not ext3 by using the conversion.
Do not be scared about ENG boot that is better, as permits you to do more things...
This one worked, cache/recovery/command is gone and cache works fine I think,

ext4 is the filesystem that comes by default on HTC devices since the middle of the last year. Think about it

Hello wonderful sgs4g community, i hope you are all excited about all our new stuff as i am. Anyways now that drhonk has built ext4 into our kernel we can now go ahead and do SOME ext4 mods. here is the guide on how to create an ext4 partition so that you can use the link2sd app so:
A:you can have an ext4 sdcard filesystem
B: create more internal space for your apps(takes away even more bloat)
Here is what you will need:
A computer
MICRO ADAPTER or USB CABLE to plug into the computer
drhonks new 2.1 bali kernel
mini tool partition wizard(or any other program that does this) you can find it here: http://download.cnet.com/Partition-...62200.html?part=dl-6285158&subj=dl&tag=button
link2sd apk you can find that here: http://forum.xda-developers.com/showthread.php?t=919326
Now go ahead and mount your sdcard to computer with the micro adapter
go into mini tool and click on your sdcard
press move/resize
go ahead and resize from 256mb 512mb or 1g off from your original size
THE UNALLOCATED WILL BE THE SIZE OF YOUR NEW PARTITION
now go to the unallocated amount and press create partition
make sure that you do ext4 and make sure it is PRIMARY not logical!!!
press apply!
bam you go ext4
now put your sdcard back in and go to link2sd
it will tell you to go into recovery and mount your sdcard
sooooo
go into cwm and go to mounts and storage then make sure you have your sdcard say UNMOUNT
reboot
go back into link2sd and click ext4 when it pops up,
NOW move all the files THAT ARE NOT SYSTEM FILES(which it wont let you do anyways) and your all done
afterwards you should have from 375mb to 440mb of free internal space
have fun
Thanks to:
Fknfocused for pushing me to do this
drhonk for the kernel ext4 patch
wizard(i saw he did the link2sd first so i decided to do it)
and the rest of the community for being awesome
Thanks brotha! im doing this right now.

it doesnt effect app2sd and to be honest you dont need app2sd after you do this trick, and im not positive about widgets i think they might be safe though
Uhh thank you for posting my name there )) well it works ... if you guys want and know how to use linux u can do it from there too ... if anyone needs help ley me know ...
Link2sd is only way I thought off to check if kernel mounts ext4 ...damn glad about that faulks

ok i did something all wackey... lol for some reason i can only see 1.89 gb of my sd card on my phone and on mini tool partition it shows that i have 12 gb in fat32 and 1.89 gb unallocated. there is nothing i can figure out on how to get the two partitions of the sd card to join back together. even the minitool thinks they are two seperate devices. does anyone know what i can do to fix this and start over from the beginning? sorry guys im a linux newbie but i am having fun while learning.
So will this work also on drhonks uv version too?

EXT4 partition and making your sgs4g ext4 are 2 different things
the partition makes a ext4 partition in your sdcard so that your sdcard can be ext4 as well
the sgs4g ext4 converter makes the OS ext4
Is there a point to partitioning my sd card with ext4 now that my OS is ext4?
Im sorry . So one more question. Im I mistaken then to think the system cache and data would be on the sd card and not the phones internal storage

Just flash in clockwork and it will format your system and data partitions back to ext3. Faster than dealing with nandroid restores.
Useful for reverting from installs using Dragon or Trinity kernels that convert you to ext4.
NOTE: This FORMATS your partitions, you WILL lose all data held on them. Your phone will NOT boot until you install a ROM ZIP file or restore a nandroid backup. YOU HAVE BEEN WARNED.
CREDIT: @paulobrien from Modaco wrote this for the O2x. I just changed the partition names to match our setup. I left his original banner in there as a result. My change amounts to about 4 bytes. If you have issues, please don't bother him, post here.
This is great...I always hesitate trying out updated or experimental kernels because of the amount of time it takes to nandroid....the cm7 kernel has been really good as of late so I've been sticking with that

wow, i never knew that. so if we are using one of your cm7 ext4 kernels and then flash a new nightly/kang we could go back to using the stock cm kernel and wouldn't have to necessarily flash your kernel again?

cwm is set up to keep whatever format you have at the time you run it, so if you are on ext4, the format command will format to ext4. It makes sense, you wouldn't want to write an ext4 fs onto a partition with vfat on it, for example. Not automatically anyway. And most users wouldn't know what to tell it to use if it were to give you the option. The forum would be full of "What file system do I use?!?!?"... The usual method is to restore a nandroid backup from stock or a stock file system. This is significantly faster.
It is of somewhat limited usefulness as many kernels/roms don't change the filesystem. However, as I switch around a lot with running tests for the cm guys, my own stuff, etc., it's nice to have a fast way to deal with it.

Yes it will wipe.
Upgrading EXT3 to EXT4 will preserve data but downgrading from EXT4 to EXT3 won't.

I recently flashed arhd which replaced my cwm recovery with 4ext. Should I need to go back to cwm, how would I do it? I presume I can't just restore a nandroid backup.
You will be able to restore a backup.
You go back to clockwork recovery if you prefer that over 4ext but it isn't a must.
Either you flash it as a zip or as image by using fastboot.

DL Clockwork manager from market....Open it, then download CWR for your phone, it will replace 4EXT. May I ask why you would do that though, wouldn't you prefer to convert to EXT4 instead?

What are the advantages of ext4 over whatever filesystem I'm on right now? I like cwm because I can name my backups right from my rom manager app. (I know you can just rename them after the fact, but it's more convenient that way lol)

I am not sure about this when referencing the current Generation(S3), on the previous Gen(S2) HTC used EXT3, Sammy had RFS(on all Galaxy). Maybe HTC uses EXT4 on Senny/Evo 3D by default, but that would make 4EXT rec useless; so I feel sensation has EXT3. And EXT4 is much faster and has journaling, these increase I/O speed compared to RFS or EXT3. However everything has to be EXT4 to see the true speed(ROM, system partitions /system /cache /data , kernel support). And I forgot to mention that I am not sure if CWR on Sens uses EXT4, on previous phone it did no converting, but I can look @ the CWR changelog.
Sorry for bumping thread!

Ext4 is a filesystem. 4ext is a recovery.
Sent from my HTC Sensation 4G using XDA App
i have just noticed this and i think 4ext is better than cwm reason been is its much faster than cwm and you can skin it and backups from cwm do work with 4ext just tried
4ext recovery is just faster, themeble and its easier to flash things. Since there are less no no no etc. For the full feature list visit madmaxx82 4EXT thread.
I recently flashed 4ext custom recovery and i noticed in there the option to convert my ext3 filesystem to a ext4.. so i put 2 and 2 together and went 4EXT recovery ext4 filesytem..
what i have noticed is that when i nandroid backup/restore my sytem partition backsup/restores very very quick with the new ext4 but my cache and data partitions take absolutely forever. so if anyone would kindly share some light on ext4 filesystems vs ext3 it'd be appreciated..(a tad familiar with linux and such so dont be afraid to get a bit technical )
