What is the best format for the SD card for our TFP's? I have 2 32gb class 10 SD cards that I want to use with my TFP and want to format it correctly the first time. Also would it be good of if I put it in my Evo3D and turned it to use either ext3 or 4 before using it in my TFP? Thanks in advance
Anyone know which wouldbe better, ntfs or fat32?
ext3 will be read by any android devices, but not natively if you mount it under windows (if you have that ... lol)with direct USB connection.
ext4 and ntfs kernel support is perhaps not natively implemented in all kernels, in custom ones and some stock ones for ext4 yes, but ntfs not sure at all..... (don't know for TFP still doesn't have mine).
that's why sdcards are still FAT32 formatted... you have heavy fragmentation, 4GB file limit, but you can read it in every OS.
If you use only network share (samba, Cifs) you can format as you want as long as the kernel support it.

Does ext4 become an option for the external SD card as well now that we have Voodoo on the internal SD? Would it not offer similar speed benefits?
What is the default format used currently FAT32? I don't know, so I'm asking.
I don't believe it's possible. Voodoo converts your system from RFS to ext4, it's not an application.

Yes. I guess what I'm asking is if the external SD will benefit from the same format. I assume it would quite be possible via PC to format the external SD to ext4, maybe using Linux.
So you want to know if you can convert the SD card to ext4? Somebody with more knowledge will have to answer that for you. But yes, the SD card is FAT 32 for sure.

I think the idea is that the ext4 partition is for apps and system functions.
The main benefits I've seen listed for ext4 are improved performance (especially for filesystem checks and file deletions), higher storage capacity and more scalability. I can't see why this wouldn't be a good idea for the external SD, particularly since the internal is already in this format.
Doesn't that make sense?
Main problem if it is possible is that you would need a linux computer to access sd cards. Windows won't read the sd's in ext4
Does that mean that the internal SD is invisible when you have Voodoo installed? I thought all Voodoo did was install the ext4 files system.
Easy way to find out is to format an sdcard as ext4 from linux and see if it works, if you don't have then just download a livecd and see if it mounts. I think the fstab entry is set to auto, but might be worth checking.
Seen as the voodoo kernel will include ext4 support, I expect this should just work but I haven't tried it myself.

You can only access user specific areas when you mount your phone as a USB storage device - /sdcard and the external SD card, if you format external SD card as EXT4 you will need a linux box to read/write to it, unless there are tools available on that other desktop os platform.

I dont agree with that , think at 5% users who used linux and on the other hand why not ntfs which is better than fat32
I would think it would work. The ext4 support is provided by a kernel module. If the module is loaded, you should be able to mount any ext4 file system. You might need to change the fstab entry for the sdcard, but it should work. I'll try it tonight and report back...

You would need the ntfs kernel module to mount an ntfs file system. I have not seen a kernel built for android that supports it (though I haven't looked too hard).

There are ext2 drivers for Windows. You can mount an ext4 filesystem as ext2, you just don't get journaling or ext4 specific features. I do it alk the time on my Windows 7 box.

Well, it doesn't work. I get an error saying the file system is unsupported, and an offer to format the SD card. Running Project V.

ext4 or NTFS
Hi
If it looks like android developpers does'nt think about ext4 for linux based kernel android that's funny.
but they also does'nt think abour NTFS for external sd card so we have limitation at 4 Go files !! and I don't understand why ? Windows PC users who should be 95% of android smartphone users can use NTFS OR fat32 as they want ? !
If u guys want ill look into ntfs or ext4 as available sd card format options =3 can't promise anything though

HI
YES GOOD NEWS !!!
I will be very very very nice
hi
when somebody said "you need linux to acces at your ext4 partition, it is right , but if this partition is in the android file system for exemple /ext_sd, it will be seen by application from android and by files management, so we don't need a pc with linux to use it, like now with ext3 sdcard partitions
we are waiting !
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.
Hi guys!
Is there some way to make our razr read/write in another filesystem than FAT32?!
My propose is watch some 1080p movies via HDMI on my TV..
Ty!
I take it they are very large video files? Fat32 has a file size limit of 4GB I believe. The only way is to use a tool to split your video files into chunks smaller than this.
As an afterthought, have you tried formatting your microsd card in windows as NTFS and copying your film across and playing on the razr (assuming you have a card big enough)? As Android is essentially Linux it should be able to read NTFS though I don't have any files big enough to test myself.
NTFS doesn't have that limit.
Good luck!
EDIT: been looking around and if you have trouble, try Drive Mount on the Android Market. You will need to be rooted & busyboxed up if you are not already. This will allow you to read NTFS formatted SD Cards
Yeah, sometimes its about 5gb files... another 12gb files..
I've got android 2.3.5, stock rom, rooted.. and NTFS, EXT2, EXT3, EXT4 are not recognize ):
The drive mount on market, is incompatible with Razr..
Thank You for response..!
Hi guys. To keep this simple, I have ordered a 64GB micro SD card and since it's so large, it opens the possibility of using my phone as a USB storage device (like external HDD).
However the issue I have is that FAT32 has a 4GB filesize limit. I tried formatting to ext2, ext3 and ext4 yesterday but the phone said the card was blank/unformatted. This seems weird as android is linux based, I thought it would have support for the default filesystem - or maybe I was formatting the wrong way?
Are there any filesystems that work on the S2 that get around the 4GB filesize limit? I've heard of yaffs2 but I can't seem to find any program that lets me format to that system.
Any ideas or am I just stuck with FAT32?
Confused its a question ??? in the wrong forum >>>and all previous posts on the subject are deleted ???

If you make a research you should find Ntfs Module.

i had the same problem with ntfs saying unformatted, but i knew it was formatted coz windows could see it... i literrally plugged it in and out a few times and then said 'scanning sd card' so i dont know :S maybe the OTG cable is connectet tight enough for power but some connecters are not making contact? ive had 3 OTG cables of which 2 i had to put at an angle to even get power and the other works perfectly apart from the odd 'sd not formatted'
If Android doesn't support the native Linux formats (ext2,3,4), then it's highly unlikely it will have NTFS support. At least the stock ROMs don't because I can't access my powered HDDs.
IMO ext4 and NTFS support should be starred on the android todo list as a top priority. What's the point in an OTG cable if the phone can't read the most common FS used in externals?
This is increasingly becoming a problem too, with this 64GB card I'm getting, there is an artificial 32GB partition size limit for FAT32 in Windows 7. I know it's artificial because I used to have 240GB FAT32 volumes before Win XP came out.
Fortunately I think you can format the full size of the card in the phone.
Hello, new micro sd card 32gb class 10 i think
What is the best file system to format it?
Thanks!
I' a noob so weight my words but I went with NTFS and everythibg is still ok.
*except my typing
Format it with the original file system of the sdcard, so you surely won't have problems, but if you're using the CustomRom Cyanogenmod it won't work with exFat, cause CM doesn't support it because of licences!
Use the phone to format the card and you should be fine. If you want to select the file system yourself, FAT32 works on 32GB cards and is the most likely to work well.
Fat32 is best for compatibility. ExFat is best for performance

Fat32 has a file size limit of 2^32 bytes (hence the name Fat32) which equivalents 4GB
If you have files (movies, ...) which are larger you need to use another filesystem.
Exfat support is very bad on linux and thus can lead to undesired results including data loss. Go with EXT4 (optimal choice) or NTFS but note that you will not be able to use a cardreader when choosing ext.
