[MOD]data2ext for CM7 - myTouch 3G Slide Android Development

Hey guys!
Just thought this would be handy for anybody with higher-class SD cards.
Keep in mind that I did NOT create the data2ext script, and BlaY0 from Legend forum was the one who came up with it in his roms, so kudos to him for making it
NOTE: a2ext and data2ext, choose ONE. You cannot run them together.
What is data2ext?
Similar to a2ext, where data/app were stored inside your ext partition of the SD card, data2ext stores the whole /data inside your ext partition.
What does that mean?
That means your internal storage will barely be used, and because nowadays higher-class SD cards runs faster than your internal memory, your phone will be able to crank out some insane benchmarks.
Requirements?
1. A good sd card with ext2/ext3 partition. suggested with at least 512MB of it (but not over 2GB, otherwise trouble will arise)
2. For now I think this will only work on the CM7 nightlies. I'll make one for CM6 if it is ever needed.
Instructions?
1. Flash it
2. Make your ext2 block size 4kb (done so by doing adb shell mke2fs -m0 -b4096 /dev/block/mmcblk0p2)
3. Go to your terminal emulator/adb shell to type data2ext --enable
4. Reboot
5. Wait some time. Files will be copied over, so the reboot will be slow.
6. Go check your storage and see how much you got
Since I was unable to run quadrant from cm7, here's the bench results done w/ 3rdsense:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I bare no responsibility for your phone breaking if you do decide to do this and something went wrong!
Enjoy.

Ha, nice. I was waiting for something like this. Now I have a new ROM, new kernel, and new extension to play with. Gonna be a fun night. Thanks ^_^

---

I must say, this was the thing I was waiting for the first time I rooted my phone so long ago.
I thank you good sir, assuming this works

---

It works just fine, I scored a 1641 on CM7 with miguel's new kernel OCed at 864.

---

Can't enable data2ext. Although I type just like it wants.

---

What's the exact error it gives you?

Can I use an 8gig memory card?

What matters is your sd card class, and the ext partition.

---

if i have s-off (if its needed) how can I put that command into terminal emulator??

---

You type it? you open terminal emulator and type it in?

haha alright didnt know if it would be same command. Im very tired, dont laugh
didnt work in terminal emu. "/dev/block/mmcblk0p2 is apparently in use by the system, will not make a filesystem here!"
also: just confirming that a wipe from recov wont mess with the data on our SD's right?

---

No it won't wipe SD data, you could try just a normal reboot, make sure nothing's using it. You could also go into recovery and enable data2ext from adb.

thanks but that doesnt help me. that error prevents me from doing anything with this. also, i said i dont want to set up adb. never use it and dont have time now.
also, obviously its being used by having a2sd?

---

Yes a2sd is the reason, disable it, enable data2ext and you'll still have a2sd since apps are stored in /data, which will be on your sdcard.

Should just be a2sd --disable or a2ext --disable, whichever you're using

I use a2sd and already tried that. run the a2sd script then says command not found

---

Then you're going to have to reflash your rom to disable a2sd
