is it worth it?
can a newb like me do it i seen a thread but just asking around

What you've seen is the ext4 hack which just makes the system run faster and is built in to a lot of kernels or the guide to mount your SD card as ext4 which is very difficult and can easily do damage to your phone.
that is what i was looking at the sd card but will it work in win7? as in readable

Only if your Windows 7 computer can read ext4, which I'm sure it doesn't do out of the box. You can download apps/drivers that will get you there, but that mod seems very complicated and the actual real world benefits are dubious to me, but your mileage may vary.

One important question in my opinion... Do any of the custom ROMs out there support SD swap partitions as of yet? I ask as a double-check... As far as my poking around goes I have yet to see anything that represents any of them would. If I'm right, this is a matter of what kernel is in use... Thereby, the real question might be if there's a kernel that supports SD card swap partitions, but I figured I'd be general just incase.
Answers? Questions? Comments?

How do i find out if i have ext 3 or 4, and where do i find ext 4 to flash if i need?
thanks
An easy way to tell would be to install 4EXT Recovery to replace CWM Recovery. It will show you exactly what your partitions are in recovery.
http://forum.xda-developers.com/showthread.php?t=1161710
If you want to change your partitions to Ext4 then you can go to the first page of the Android Revolution HD thread in development and download and run Mike1986's superwipe script, which is on the first page. Flash superwipe in recovery. It will format your partitions as Ext4. Make a back up of your phone data because it will delete all of your data. It will not delete anything on your external sd card. Also make sure you have a rom on your sd card to flash after using a wipe script.

What wolf said lol. :-D.
Enjoy the ext4 recovery. Its a great piece of work. If you want to theme it check out the links in the op of that thread wolf directed you to. Many themers including myself are listed on there. Link in my sig as well.
I got your 10 char right here
Besides really liking the way 4EXT Recovery works, I really enjoy changing and using themes by Cwhitney24 and other themers. It is great to be able to theme recovery.

Are there any advantages of being ext4 over ext3? Im on the absolution rom so im not sure what ext it is. Sorry for thread jacking btw.
EXT is the Linux native filesystem. EXT was quickly replaced by EXT2 which was a good rock-solid FS for Linux and survived for a decade. It was eventually supplemented with a journal and became EXT3 even though the underlying filesystem was still EXT2. EXT4 is a journaling FS, but was redesigned from the ground up. It is designed to take advantage of very high-speed drives like 15K SCSI raid-arrays in high-end server farms, or for dealing with huge file sizes efficiently, neither of which is an advantage at all on an embedded device like a smart phone.
Most Androids used yaffs2 since it was fast and efficient on an embedded device with a serial MMC type storage system, but with the advent of multi-core smartphones, yaffs2 didn't handle multi-threaded access to the filesystem.
So, in short, EXT4 is really not an appropriate filesystem for an embedded device. Any journalling filesystem is going to be hard on the MMC as it causes much more read/write cycles and will eventually result in faster failure of the MMC. EXT3 is the choice of HTC on its newer eMMC devices and probably is the best fit for multi-core systems, but Google has hired the inventor of EXT4 so that's probably the direction Android will take regardless of EXT4's inappropriateness.

When I wipe my Dalvik Cache I get the following message on the screen:
E:unknown volume for path [/sd-ext]
Is this normal?
That's normal. I believe the reason for that is because you don't have an ext4 partition on your SD.

Should I have an ext4 partition on my SD? What are the benefits?
/sd-ext does not exist for our phones. Totally normal that you get an error.
Supposedly it speeds up your app cache on sd card read times, but unless you have a really fast card, I don't really see the benefits. Used to be more useful before the Froyo days.

Didn't dsexton702 have an ext4 converter for the SD card as well? It was back then before he even released ICBINB Froyo.

I am running Raver's Octane ROM which is based off of Gingerbread. I haven't had any problems running the ROM so far and am quite happy with it. But just wanted to make sure I wasn't missing something. So, I guess what I'm asking is, if it's ok to run as is or should I convert my sdcard?
You don't need ext4 on your SD card. 95% the custom ROMs on this forum practically have ext4 (lagfix) built into it already.
Noticed today I'm able to move almost all of my apps to SD and not just the supported ones without having done anything but installing a rooted stock ROM and some standard goodies (SU, BusyBox, ROM Manager and Titanium Backup). Wondering if it was enabled by any of the above? the rooted ROM? or the stock ROM?
any takers?
Titanium backup, in "batch", has option to move all apps to either sd or internal memory.

It's not true A2SD. Just a bunch of buggy symlinks in /data and incomprehensible files in /sdcard/.android-secure that Google is trying to pass off as A2SD.

thanks. i rooted my phone right after the first stock boot so i couldn't tell if it came that way. It's just odd coming from 2.2 that everything all of a sudden is now movable, despite being not true a2sd.

I know. Just because a bunch of people find hitting "partition SD card" in ClockworkMod Recovery too difficult doesn't mean those of us who want the full potential of our phones unlocked should suffer, but we're stuck until someone finds us the mountpoint for sd-ext.

you all need to check out link2sd (free app) it will let you install apps to ext partition. I myself use it and have a 8gb ext3 partition with over 550+ apps/games installed. It also lets you decide if you want to move dalvikcache and library files to ext to save more internal space. I used mini tool partition app on my pc to create a larger ext partition then cwm would allow.

WIP Memory Address Listing
You need to know where to put and access the data, explicitly, in order to be able to use that location.
Android does this by using mount-points, which translates to the memory address where it should be looking for the information.
The thread I linked to is one I started so that we can discover them all, and what mount points correspond to what memory address.
Please make sure to read post number 8 in the thread by dhkr234 which spells out a good caution about using memory addresses directly and why you should be using mount points instead.
If anyone makes any headway in learning anything we don't know so far, please post it in that thread so we can get a comprehensive listing of mount points and what memory addresses they correspond to.
I've been extremely busy on other projects, but if someone is going to come by and make A2SD available for us, having a road-map for them to follow already sitting here will make their life a lot easier. ( ...and maybe encourage someone to do it because the info is sitting there. )
...and yes, it is specific to our device. Every device addresses the internal memory differently and that makes the mount-points unique to each and every device.
gotcha, so...piecing this all together, does that mean that a true A2SD shouldn't rely on symlink at all and Link2SD (what d12unk13astard recommended) is essentially just another hack?

The real A2SD is not "just another hack," it's one of the ORIGINAL post-root hacks pioneers like JesusFreke came up with. It allows you to put your apps on an EXT partition of your SD card, and you can resize that partition if your computer runs a Linux distribution.

dhkr234 said it good there.
I linked so someone who wants more of an explanation can follow and read up.
In short, you can very easily write to the wrong memory address.
This means:
Installing some silly game over parts of both your boot partition and recovery partition would give you a cool slide-paperweight.
Mount points prevent this from happening by ensuring the data is written to the proper memory addresses.
sorry for noob post but i havnt been able to understand all this with all the posts iv read
Iv been looking into installing apps on the external sd card and i came across "partitioning sd card" and a whole bunch of other vocabulary, so iv got a couple of questions.
1. can someone explain to me the basics of this?
2. define ext2, ext3, ext4, fat32, swap size, (there might be a bit more i jsut cant think of any right now)
3. do u reccomend doing this with cwm? iv come across a few posts where people have been saying thing could brick your phone
4. apperntly cwm has some built in partition? i dont really know..
5. how would I do this this with cwm?

EXT4 is the file system (like FAT or NTFS but for Linux based). Swap is the partition used sort of like ram (just slower) in the way that temporary files are stored there for quick access.

I think people mentioned to do it through clockword mod? I think I've seen an option down there.
I have no idea why you'd want to, though. I can't really see any benefit and it would only complicate things.
Only reason to partition sdcard to have an ext partition is for people like me that have way too many apps to install that normally wouldn't fit on the g2x's internal storage. Even putting apps to SD wouldn't allow my setup of over 600 apps to my phone without an app called link2sd, currently rocking a 12gb ext3 partition on my 32gb class 10 Lexar sdcard. Call me crazy but I love having all my apps available any time I need, my phone is a beast I tell ya, with all the stress I put in it its still blazingly quick!
