Change of SD card

Hey guys, currently i'm using a 1gb sd card with cyan rom installed to my htc dream phone.
If I want to change to a higher capacity sd card, how should i go about doing it? In terms of the applications and stuffs?

Do you have your sdcard partitioned in any way? if its only a fat32 formatted card, you can simply format the new one fat32 and copy all files from the old card to the new. If you have it partitioned, match the smaller partitions on the new card (match sizes of ext 2/3/3 and linux swap if you have one and copy files accordingly) and copy old fat32 stored files onto new one (the fat32 partition size difference should not effect anything). I've tried this myself a few months back upgrading from a 4gb class 4 to an 8gb class 6 and I had no issues. Just be sure both cards were partitioned with the same program if you are using linux [I run Ubuntu], otherwise you may run into admin permission problems

Mine is formatted in the way in this site: http://wiki.cyanogenmod.com/index.php/Full_Update_Guide_-_G1/Dream/Magic32B_Firmware_to_CyanogenMod
So how should I go about doing it?

[Q] SGS Storages types summary?

RAM 512Mb but you only have aprox 326 Mb for yourself, the rest are used by the OS and System Services.
Internal SD, can come in 8GB models or 16GB models
External SD, is whatever SDHC micro SD card you want to insert into it, supports up to 32GB micro SD cards
the Internal SD is split in 2 GB for System OS Apps, and whatever is left over is yours to use.
the Internal SD is aprox a Class 4 SD card

Amd what about system types on internal sd? What is reason for so slow stock i/o? FS type? LagFix i choosed store data on same chip...

exactly because of that the internal SD is split into 2 active partitions, by having the swap file on another SD card, then it lessen the access time

Ok! But..... CFLagFix-1.70 moves files to internal SD, not external.
It was in internal, and became also internal. So what's the difference?
Ok, maybe another partition, but same storage! May by file system structure, heard about some journals??? or what else??

[Q] EXT2 on external SD

Tell me please, is it possible to use the external SD card other than the FAT file system and how it can be implemented? When i connect an SD card with file system Ext2, the system reports that the card is empty or corrupted.

SD Card's partitions

Hi
I partition my SD card in nAa-11 recovery (256 SWAP and 768 EXT, 7 GB free), and now I can't restore it to his original condition - 8GB. Windows didn't see 8GB, just 7GB and I can format it, but it always shows 7GB as the total available space.
Any ideas, guys? I have to remount dis partitions in terminal emulator, or what?

You need to use a Partition Tool that supports Linux partitions, like GParted.
EDIT: A more easy way is repartitioning your SD from Recovery, setting SWAP and EXT to 0.

Use SDFormatter V3.1 and make sure you select format size adjustment ON option. A quick format should be ok.

use your android fone to format sd card.. in settings go to sd card and phone storage settings then unmount your sd card and then format it.. after formatting mount it back and now your partiotion was gone you can now see your 8 gb storage

try to mount your sdcard to your computer using a card reader, then re-format with GParted (if you're using Linux) or Mini Tool Partition Wizard (if you're using Windows)

Not sure if this is the right place to ask this question, but:
I partitioned my memory card into 2 so I could install apps to sd card using Link2sd. The first partition where all the data was being saved got corrupted and had to be formated. In the process I have lost all the data that came on it originally. I have tried using the Android File Recovery, it does recovers all the files, but the directory structure is lost.
Is there any way I could get the data back that was there originally?
The partitions on card are in Fat32 format.

Migration to the bigger SD card

What would be the best way for migrating contents of the current SD card to the new bigger one?

I would copy them using a computer.

I am concerned about file permissions.
For now as I have plenty internal storage, I am considering an option to tar the files from the old SD card, and than, after formatting the new SD card, untar eventing, respecting permissions.
I have installed busybox.
Another option would be to create dd image of the old SD card, Mount it, than format the new SD card, and copy everything from mounted image back to the card.
These two are only ways to preserve file permissions, aren't they?

The sdcards are formatted as fat32, right? No problem. Simply copy everything from one card to the other, as per the first advice.

In that case, you are right, thanks.

I have put small SD card into computer and rsync-ed is contents to the temporary folder. Than I have put bigger SD card and rsync-ed back.
Everything went ok.
Thanks.
