I went through Revs youtube video of setting up fat32 and ext2 partition step by step. When I connect to PC and view from Gparted it shows my partitions but whenever I try to access as E drive it says sd must be formatted.
I have tried searching around for how to fix but I have not been able to find anything? Anyone have any tips or anything similiar happen?
I haven't watched that video in a while, but I think probably what you're running into is that Windows can't read/understand/access ext2. ext2 is a filesystem developed for linux. Android uses linux, so it should be able to access it.

Hi,
I have sucessfully moved my apps and caches to my 1.6gb ext2 partiton on my 8gb sd card.
I would like to back up the ext2 partition in case my sdcard fails.
How do I do this in windows xp?
Thanks
I'd love to find out how to do something similar. I just got an 8 GB card that I'd like to replace my 2 GB card with, basically, I'd like to clone the whole thing over.
Anyone have any ideas? I can do XP or Linux, just curious what software would be able to do the best job of replicating the card from one to the other.
Attach the card to your computer with an adapter (not the phone as it will be mounted by android). Download and install ext2ifs from here. You will now be able to see the files on the ext2 partition and can copy/paste them to where ever you would like.
Thanks, but I've had no luck with ext2ifs and memory cards. They even address it in their troubleshooting section:
I have a device with a removable media, for example a USB memory stick, a Compact Flash Card, a magneto-optical drive etc., which has a partitioned format and has more than one partition. When I insert that media, a drive letter appears for the first partition, but not for all the remaining partitions of the media. When I open "IFS Drives" of the control panel, the considered device appears as a hard disk drive, but there is no partitioning scheme shown for it. How can I create drive letters for the remaining partitions of that removable media? (USB hard disk drives are not affected.)
There is an unsatisfactory answer only: it is not possible.
Windows creates (and deletes) all the drive letters for pure removable devices or removable medias itself. Because the Ext2 IFS software need not to create them, it intentionally does not show any partition scheme for that drive.
Windows creates a drive letter for the first partition of the considered media, but not for the remaining ones. (Windows NT4, 2000 and even XP behave the same way in that regard).
You will run into the same problem if you have a removable media partitioned with two partitions of the FAT type on a computer, which has not installed the Ext2 IFS software! So there is one straight advice only: do not use removable media with more than one partition with Windows.
I'm guessing (someone else could correct if wrong) that if I were to just do the basic copy from one card to another - that would suffice?
If I just took the card, created two partitions (FAT32 and EXT2FS) on the larger card, then copied over all the files in both - that would work just fine?
Strange, I've never experienced any issues with ext2ifs, but yes a simple copy paste of both partitions has been all i needed. Just make sure to copy any hidden files as well.
Can we back it up using Ubuntu Live CD and just upload them to a new sd cards ext2 partition?
yes, but you would need multiple card readers.

Why can't you save it to the hard drive, replace the sd card, access the ext2 partition and upload the files that you backed up?
Although I'm not very familiar with Ubuntu, when I tried it last time it didn't even allow me to have access to the app and app-private folders within the partition.
What do I need to do to be able to back it up to the hard drive so I can try to upload it to another SD?
Hi,
Thanks for the suggestion.
But when I installed the driver, I can still see just the fat32 partition not the ext2 partition.
I am using a sdhc usb card reader so it is not connected to the g1.
It is like the ext2 partition does not exist through windows xp.
But when I put the card back in the g1 the files are taking up space through ternminal emulator. So the ext2 partiton does exist but still not accessable through windows.
Any other ideas?

what comes up when you use
"busybox df -h" in the terminal emulator?
make sure you see something like "/dev/mmcblk0p2 (partition size) (used) (available) (used %) "/system/sd"
If not then that's the problem.
Hi,
In my phone , I do have that ext2 line /dev/mmcblk0p2
size 1.4gb - used 49 meg - free 1.3 gb
sdcard line /dev/mmcblk0p1
size 6.2 gb - used 5.2gb - free 981 meg
Thanks for the reply.

If you're on Linux it is trivial to get the files off, if you'd like to make an exact image you can use the dd command. I suggest grabbing a live CD, as it will be a much easier process than making windows see ext partitions.

I have the Live CD, but can you elaborate on the "dd command" exactly. I'm a Linux noob and wouldn't mind backing up the partition. Last time I tried, I couldn't even get permissions to open the files no less copy them.
Thanks.
Insert the two SD cards into USB SDHC card readers. Launch the free MiniTool Partition Wizard program. Copy the ext2 partition you want to transfer on the first SD card to an unallocated area on the second SD card. MiniTool Partition Wizard under Windows does "see" multiple partitions on a USB drive even though Windows doesn't assign letters to those drives and they are invisible in Windows Explorer.
To increase the size of the ext2 partition on either SD card, use the Linux program GParted. Boot up with the GParted Live CD/USB iso file. Run GParted to resize the ext2 partition. (MiniTool Partition Wizard can move but not resize an ext2 partition.)
Can anyone please tell me how I can get to know which partition I am using.. I partitioned using ClockworkMod Recovery 5.0.2.8... So thats why I have no idea..! :S
I think that recovery will make an ext2 partition, but not 100% sure. Easiest way to check is probably to connect your micro SD card to your computer (in a card reader, I don't think it will work in the phone, although I'm not completely sure) and run a partition manager like MiniTool Partition Wizard (http://www.partitionwizard.com/free-partition-manager.html). It should show all drives connected to your computer, and within each drive, all the partitions, along with their format etc. Find the drive corresponding to your SD card (probably the only one with an ext partition) and look at the format of the ext partition.
This assumes you run Windows. If you run Linux, it should natively detect both partitions on the card, although depending on your distro it may or may not automatically mount them. I can't really help too much with that aspect of things, but I'd say if you are the sort to run Linux, you'll have a fair idea where to go from there.

Okay thanks...
Sent from my HTC Explorer A310e using xda app-developers app
I have tried an app called "easeus" and that gave me heaps of trouble with my tablet. I've tried others like hp usb format and while TWRP can see my sdcard, cm10.1 cannot see it. I've also tried apps where it can't see my sdcard.
thanks for the help
I'd reckon Gparted is your best bet. If you have Linux available you could install it just like any other normal app, but I understand you're on a WIndows box. It's probably even more convenient: download the ISO file of Gparted -- it is bootable, so after you've burned it to disc you can leave the disc in your PC and boot up in the Gparted environment. You can partition afresh, move, resize, flag, etcetera.
Lots of partition programs seem to garner funky results under Windows -- for my external card partition I've completely crossed over to Gparted.
thanks heaps. seems to have fix my on-going problem of random app crashes!! never realized it was related to my badly formatted sdcard!!!
Hi - I have a galaxy s3 mini (GT-I8190N) and rooted about a year ago following instructions on a thread at XDA and it has worked perfectly with 16 Gig SD with about 3 Gig partitioned for Link2SD. So now I am attempting to go with a 32 Gig with a bigger SD partition as my old memory is pretty full. I hit a problem and cant fix it.
I managed to back up all the data to the computer running on windows 7. I couldn't get Ext2 Volume Manager to mount the partition so I used a read only program called Disk Internals.
The new 32 Gig is partitioned about 20/10 Gig (FAT32/Ext2) both as primary (Used minitool partition wizard). Got the back up data to the FAT32 side now I can not mount the partition again using Ext2 Volume Manager. I tried another program called Ext2IFS but it doesn't work on windows 7. I tried another computer also windows 7 and it is the same problem.
Specifically what happens is the Linux partition is recognized as PARTITION 2. When I double click on it to activate the mount points, the status indicates STOPPED. I also tried this on a old windows XP and have the same problem, also I cannot get Ext2IFS to work on the XP either.
As you can see this is becoming a painful exercise and if anyone can point me in the right direction I would be grateful. I only now need to copy the old data onto the new Ext2 partition to complete the task.
Cheers
Simon
You busy bots aren't answering
Howabout I create a linux partition on the comp and figure out the basics of linux. I reckon that would work. What you think please?
Just in case anyone has a mount problem with Ext2 FSD in the future. This is how I fixed it.
I am using an old dell laptop with windows 7
I was going to make a fresh partition for Linux but decided to use a virtual machine.
Oracle VM VirtualBox didn't work for me so I tried VMware Player and it worked fine. Loads of tutorials around just try to find one with a decent count and good reviews. Make sure 10 to 20 GIG free space available.
Get the Linux flavor from from the developer as an ISO.. Loads of tutorials again out there. Once it is in and working the file transfer is simple apart from you may need root /elevated permission level to move some of the files.
Hi All,
I'm trying to get my new 4tb drive to work with my android device. I know that out of the box it requires FAT32 to be read, and no I am not interested in rooting my device to install drivers to support other options. I already have another 4tb working :
https://www.amazon.com/gp/product/B00HXAV0X6/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
this drive formatted just fine using the guiformat tool to fat32.
however the recent drive does not accept a fat32 format:
https://www.amazon.com/gp/product/B0196J3UZ2/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
gives me a format error and restricts me to a 2tb volume.
I believe the problem for this is that the first drive is a raid0 format with 2 drives built in. The second drive is a single 4tb, slower but more "dependable" (and also $70 cheaper).
I'm sure my success with the first drive is that the fat32 partition is able to create > 2tb because the physical devices are split between 2 2tb drives, though this does not make a ton of sense to me.
Regardless, what are my options here for the second drive? Again, i'm not interested in rooting my device. 2 partitions are ok, but i've experimented w/that and found that the second partition is ignored in the android file system. Did some reading and found that part1 needs to be vfat, and part2 needs to be fat32, AND you need to possibly be on root and run a special script to even mount that setup. I'm not interested in all that, i just want to be able to turn my device on and have the drive mounted w/o root.
All that said, what is the simplest solution for me to set up this drive to be read on my Samsung and s2 tablet devices w/o root? Is FAT32 the only solution, and if so, can i some how FORCE this partition style on my 4tb drive? I read somewhere that a Linux boot can handle this, though i don't even know where to begin with that being a windows man.
Please help!
anyone have an idea? dont want to spend an extra 70 bucks just because i cant format a drive to fat32 ;/

Android likes ext4 more than fat32. You should try with it, but it is a bit problematic as windows does not support ext4 at all. You need to get a live Ubuntu USB or something and you should be running linux in a matter of minutes (it won't uninstall Linux unless you explicitly tell it to)
From what I understand if your drive has mbr it is limited to 2 TB. Whereas gpt can exceed 2 TB. You will want to convert to gpt. If you search google there are articles that go step by step. I experienced a similar issue with my 4 TB Seagate external usb 3.0 drive. I deleted my partitions using a Windows computer and reinitialized the drive for gpt. Afterwards I formatted it in exfat.
