E: unknown volume for path [/sd-ext]

How do I fix this? I made an EXT partition of 256mb and I even tried formatting the sd card. Using a Patriot 16gb Micro sd Class 10 (don't know if that is relevant)
Also installed the recovery from fastboot. CWM 3.0.0.5

Where are you getting this error? Are you trying to set up Apps2ext? I think currently that only works on Enomther's ROM. If you aren't trying to run Apps2Ext, what is the EXT partition on your SD card for?

Apps2EXT is the same as Apps2SD right? If that's the case then yeah that's what I'm trying to do. I thought EXT Partition works with CM7? If not then guess I'll stop trying. I get that error in recovery when I wipe Dalvik Cache and when I try to mount SD-EXT Partition or when I try to format it.

Apps2sd and Apps2sd are two diffreant thing apps2sd stores apps on a FAT formatted sdcard (which is what Froyo uses as native apps2sd with apps that allow it and no widgets) , while apps2ext stores apps on a partition on your sd card formatted to EXT file system, which your phone mounts as part of its internal system so it will support widgets and apps that previously could only be supported on internal storage, so it considers it internal storage even though its on the sd card, so no they are not the same thing, right now the only rom that supports apps2ext is Enoms rom.

I think nowawdays Apps2SD is used to refer to the system built-in to Froyo for moving apps to the SD card (does not use ext file system or need special partitioning). This just works out of the box on any Vision ROM.
CM7 uses the ext4 filesystem for all of it's partitions, which is new (not sure if that's what you are talking about). Hadn't heard it supports Apps2Ext, but maybe?
If you aren't using Apps2Ext though, you should expect to see a warning about a missing sd-ext partition when doing that stuff in recovery, so you're okay.

[Q] How to install Custom ROM on SD card ?

Hey guys ! The primary reason I switched to a custom ROM was because the HTC internal storage is VERY small. The /data partition is almost a joke.
I installed the Custom ROM of CM 7.0.2 and am pretty much back to square one. So, how do I install a ROM on the SD Card ? Do I need to format the card to ext3 or ext4 and then make manual partitions ?

Same reason here initially. Just install a rom with a2sd+ and you wont have any problems. You do need an ext partition for that tho.

You can also change your partition table than you have more space on your /data partition but you have to be S-OFF to do that.
Here's a tutorial to S-OFF: [Video Tutorial] Noob Proof Everything Desire Guide UPDATED (Go to STEP FOUR)
Here's the alpharev site (there are the partition tables): AlphaRev
Because your're using CyanogenMod you can use the Bravo CM7 table.
You can also use A2SD but your SD-card is slower than the internal storage. And yes for A2SD you need a fat32+ext3/4 partition. A tutorial how-to partitioning your SD-card is in the link above, it's STEP FIVE.

Thank you!

[Q] Change ROM from ext3 to 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

Possable to make a 1gb EXT4 with out format?

Every sense ROM requires a ext4 so i was wondering if i could make a partion of 1gb on my SD card with out reformatting, if this is possible any links or help would be appreciated.
thanks

Try MiniTool Partition Wizard.. [sometimes] allows you to resize your FAT32 partition and put in an ext4 and change both to primary....
Sometimes it lets me resize, sometimes it doesn't. Have yet to figure out why though..

Don't use mini partition wizard. Many users reported it destroyed their sd card. So use GParted, it's worth it to deal with this software.

Not all sense roms need a partition, try cool bravos

Recently I partitioned my sd card with gparted and vmware. Didn't had to format card. Gparted managed everything. Very powerfull and easy tool.
Just follow @rootSU guide.

You can convert ext3 partition to ext4 by 4EXTRecovery, You don't lose any data from the partition sdcard.
http://forum.xda-developers.com/showthread.php?t=1154221
Or you can use the file from coolex that your partition convert ext3 to ext4, just flash the same like rom from recovery.

Yeah that's a bit slow but you could give it a try. I started with a class 2 card, too. Then I switched to class 6 because of the speed.

If you already have ext partition use recovery to convert it to ext4 as advised by Gramzz. if not its better to make backup and recreate FAT32 and ext4 partition you can also do this using recovery or use Gparted on computer.

[Q] ext4 What is it?!

I have been using a custom ROM for a while now and I have been seeing in the thread that many people are using ext4.
I have asked many times in the thread and recieved no reply.
So my question to you is what is "ext4" and what bennifit will it be to me as a Desire owner.
Thanks

1. Google is your friend
EXT4 is a file format used by Linux (Android = Linux). When threads talk about EXT4, they are referring to creating an EXT4 partition on your SD-Card e.g. have 14GB FAT32 and 1GB EXT4 (from 16GB SD-Card.. 1GB is always non-existent)
What having an EXT4 partition enables you to do, is to have Apps/Data2EXT scripts which move apps to the EXT partition, giving you a lot more internal space.

Moving some of the app data to the sd-card is different to having an EXT partition and A2SD.
If you activate A2SD, the system will install and store your apps on the EXT partition, and your internal memory will not be filled up, and will remain at xxxMB. Furthermore, with an EXT partition you can use D2EXT, which makes your phone use the EXT partition as the data partition, so if you have 1GB EXT4, your phone will see 1GB memory.
If you use the inbuilt "move to sdcard" function, it only moves some of the sd-card to the android-secure folder on your sd-card, however your internal memory is still used up.

In addition, moving apps to sd-ext partition doesn't break app widgets like the stock app2sd method that Gingerbread use.

Reason: With A2SD / DATA2SD / etc. Android still "thinks and tells" the Apps are still installed in the internal memory (at least this tells me my logic).

That's how I see it as well. And makes apps available to use when you have it on usb transfer mode.

MatDrOid, since you are also on MW. How do I make use of my ext4 partition I created?
I am guessing there is a way to just move to the ext4 via a app?

if it's MW based on oxygen, instructions on how to enable ext4 partition are in the first post, no need to use an app.

No it's the cm version using s2e and I think it's working lol

backup your sd card 1st
then use only 4ext recovery (requires s-off to change recovery) or gparted to create your partition (step 5 here)
