Copying Ext4 data2sd files from one card to another? - Android Q&A, Help & Troubleshooting

I was able to pick up a class 10 32gb micro sd card for $45 from Future Shop today. I currently have a 8gb class 4 card in my Desire with a 500mb ext4 partition for my data2sd and then the rest as fat32. I partitioned my 32gb with a 5gb ext4 and everything else as fat32. I want to copy the files from my 500mb ext4 to my 5gb ext4 but I can't seem to mount it in Ubuntu, OSX Lion or Win7. Can anyone tell me how to mount both ext4 so I can copy all my files from one to the other. Also do I need to run my data2sd script for my new card?
Thanks!

[Q] EXT3 Partition Exists - but - how to use it?

Hi there pals, after buying HTC Desire second hand I'd like to make FAT32 and EXT3 partitions... I burnt GParted and saw that those partitions exist, so no need for it...
EXT3 has 1GB (in gparted written that is 116MB used???) other is FAT32 - 8GB SD card from previous nokia 5800.
I downloaded every bigger application to test saving files, and from cca. 60mb's internal memory now I'm on 26mb's, obviously nothing goes on that EXT3 partition?
I wanna know how to make my phone install aplications on that EXT3 partiotion not internal memory which is almost full?
Thankful!
I'm using HTC Desire with OXYGEN ROM, some 8GB SDCard!

[Q] SD card file-system and the 2GB per file limitation

As far as I know the SD is formatted as Fat32 and we are limited according to its specs. It means we can't write a file larger than 2GB on it.
Is there any way to format an SD card for Nook as NTFS, ext2, ext3 or anything R/W supported in Windows or OS X natively (or with additional drivers)?

Windows supports two filesystems: fat, and ntfs.
Of those two, Android only supports fat.
So... no.

That's a shame. I was downloading a video file larger than 2GB and then my Nook suddenly got rebooted and I realized about the limitation...
And the file size limit is not 2gb but 4gb

so it's Fat32 then? not Fat.

ok. 2gb is for fat and 4gb is for fat32 I guess.

Window also supports exFAT with file size limit, which is exceeding contemporary mobile storage devices maximum capacity, but, unfortunately, Android doesn't support this file system.
As an alternative, I've tried formating my SD to ext4(Ext2Fsd allows to mount ext2-3-4 partitions on Windows), but NT didn't recognize it.
I found a utility called Drive Mount, it can mount storage device with FAT/NTFS/EXT file systems, but it doesn't support Android 2.x.
I also tried to mount my SD manually, but Nook Tablet handles SD card in a way unfamiliar to me.
If you insert FAT formatted SD card, then NT will mount SD(block device /dev/block/vold/179:17), but if you insert ext4 formatted card(I bet the same goes for ext3 and ext2 too), then NT will not mount anything and /dev/block/vold/179:17 will be inaccessible(the device still will be at /dev/block/vold, but both cat and mount will tell you that there is no such device or address).
UPDATE
I was able to mount ext4 formated SD card via /dev/block/mmcblk1p1
NT thinks that SD card is blank or has unsupported file system, but it is fully accessible for both read and write.
So if you desperately want to watch some 4+Gb video, you need to format SD to ext2/3/4 and mount it to some empty folder on your NT internal partition, I wouldn't recommend using /mnt/sdcard, though.
If somebody interested, I can make a step-by-step instruction for Windows users.

8gb+ microsd cards & 4gb fat32 limit

just wondering how ppl have got around the fat32 limit on their 8gb+ cards? anyone got ntfs-3g or some other file system working to be able to use 4gb+ files on their phones?
Tried formatting the card with ext2/3/4?
Fat32 is limited to 4GB files, end of story. You could try ext4 but you might havve some trouble copying files.
But i have my micro SDHC 8GB formated at fat 32
Trying ext* was my initial thought but wanted to avoid getting into a situation where I have to install ext drivers on a windows host (netcafe/library- or friends-computer-type situation), hence the ntfs question.
I realise fat32 is limited to 4gb files, that was the point of the post.
Just wondering what others have tried already.

[Q] SD Card Partition Problem

hi guys,
I partitioned sd card ext with 1GB with FAT32 using mini partion tool
when boot ON the Phone & using with LINK2SD Main sd card & ext sd card showing the same size of 1GB ....
is the problem with ROM ??
I tried with another sd card but the issue is same
i'm using stock rom & 16 GB Sandisk C10 sd card
Pls help me......
Link2SD
The XPERIA X10i running GB 2.3 is a bit problematic with partitions.
The OS only mounts the first partition it finds and that's normally the second partition. Doh!!
The following patch may be of some help to you
SE2.3.3-link2sd-patch.zip
It is assumed you have formatted both partitions as primary.
Everybody should use Link2SD if they have an XPERIA X10, just because most quality class6/class10 cards have better read/write speed than internal flash and with a 1-2GB sdext2 partition more space too.
Considerations
I'd format the second partition as ext3 and 2GB if Link2SD is to be used, especially if a gamer.
I would only use a class6/class10 'quality' 32GB microSD card or greater.
Copy the contents of the /data/sdext2 partition to a NAS/external server
(1) I'd format the partition to be used with Link2SD as ext3 ( I've found on my builds I can't use ext4, but would, if I could ), just because it'll give better performance. In a gaming environment 1GB can be used up pretty quickly if libraries and data are linked too.
(2) The cost of quality class6/class10 microSD cards has really dropped in price now that extreme and extreme pro cards (50MB+ write) are all the rage. It's just a pain having to rebuild a working Link2SD environment onto a larger card at a later date, when a lesser card, no longer meets needs.
But given I'm using a 64GB card, I would say that.
(3) If you copy the contents of the second partition to a linux system /folder it makes a great recovery, as you only have to restore the Link2SD second partition and you get all your apps back, data and all. I copy my /data/sdext2 partition onto my NAS every now and then and it has saved my bacon a few times when microSD/SD cards have gone belly up.
