Root G-Parted and SD Card

dazek · Dec 4, 2011

Hi

I am installing a custom rom for the first time. First though I partitioned the SD card (16gb) in G-Parted. (In the hope of putting the apps on the SD card)

I created a partition table and then made the following partitions

Linux Swap 32Mb
Ext 2 1Gb
Fat 32 - Remainder of space (Around 14Gb)

When I go back into windows, it will not recognize the card at all (not even the Fat 32 bit). This means I can't put the ROM onto the card.

I tried formatting the card through Recovery mode in Clockwork recovery - all It did was convert the Ext 2 partition to FAT 32. Windows could now see this - of course only 1Gb though. i also tried with Ext 4 on the second partition - still the same problem.

Can anyone please help?

Cheers

Read the root memory faq (from the "all about rooting" sticky post, red link in my sig). There are instructions there for how to partition for a2sd. See the section "If I wanted to do it, is there a step by step process? ".

You want 2 partitions, fat32 followed by ext. Swap is not needed, but order of partitions is important. Don't use recovery for partitioning - performance will be better with GParted. Also I'd use ext3 rather than ext2.

Im guessing you watched the video. its a bit wrong tbh
you should always have the fat32 partition first then ext then swap (if the rom/kernel requires swap as most desire roms dont)

I did watch the video!!

I just converted the card back to all Fat 32 and windows read it again.

I guessed then that the order was important!

i am now going to reformat in Gparted with FAT 32 first.

I will get rid of the SWAP also then

Thanks guys

Fortunately had VM workstation so don't have to keep rebooting my machine

hi Guys

I have the rom installed now (insertcoin) and seems to be working fine. I just have a couple of questions: -

I obviously rooted my phone first, then sorted the SD card out with Gparted. Then put the ROM on and installed. I never went through any gold card or unlocking process. Is this a mistake?

Can you point me to somewhere online that tells me how to get the apps now to install to the SD card?

Many thanks

Daz

read the root memory faq. all is explained there

as for the goldcard, its only needed to debrand and flash non carrier specific RUU's so tbh its not really a problem

OK read it and go the app2sd script but now I can't get back into clockwork recovery.

Would this have gone when I flashed the ROM and if so how do I get it back?

Thanks for the help BTW!

no its cos insert coin has "fastbooting" so it doesnt fully turn off
you can turn this off somewhere in the settings menu.
if you cant find it just pull the battery then boot using voldown + power.

the faq im refering too just tells you about the behaviours of different methods.
im not sure what script you are refering too.

you need to read everything in our stickies
and also for each rom you flash you need to read the devs notes fully

no problem - good job you told me

I was just about to flash Dark Tremor's App2SD

[Script][A2SD]Darktremor 2.7.5.3 Beta 04 [HeroCDMA] (01/29/2011) - xda-developers

That's what I understood from the stickies

I had a look in the documentation and forums. From what I gather it says you don't need app2sd with Insertcoin as it moves them there already. I changed the setting for this.

As a test - I put Angry birds on - 21.5Mb. Only 2 Mb more of phone space used (18mb went up to 20Mb used)

Hooked up the phone on a Linux virtual machine - I checked the Ext 3 partition - I can see the Dalvik cache with 1mb of Angry bird files in there but can't find the main Angry Bird files. If I move Angry Birds to the SD (The Fat 32 partition), I can see the ASEC file there and I gain 2 more Mb space.

All very confusing to me, but it seems it is already putting the bulk of the app into the ext 3 partition on the SD card

it doesnt move the libs afaik just the apk and the dalvic
when you use built in apps2sd (not a2sd script) on GB it moves apk and libs to asec leaving the dalvic.
in this instance a2sd is still the better option unless you have a custom hboot/mtd layout with loads of data headroom
