Does my ext3 partition need to be formated in Linux?

A while back ago I purchased a Disc with all kinds of recovery and maintenance programs for all versions of Winders from a company called "Spotmau". One of the uitlities in BootCare is a great partitioning program called Partition Genius, that enables you to move, shrink, add/subtract partitions without having to wipe entire drive. Specifically, I am able to modify an SD Micro card without having to flip the non-removable bit.
My question is, should I just leave the new ext3 or ext4 partition as such or should I go ahead and format it in Linux? The program has the ability for this.
This is a bootup CD so you'll work in a non-winders environment but it does the trick really good.
G1, on AT&T
CyanogenMod 4.2.13
16GB Sandisk SDHC.

Just use the recovery image in my sig, no need to have a card reader or anything extra on the computer.
Filp the non-removable bit?

Non-Removable bit
I was taught that a PC will not partition an SD card or a USB flash drive because it is addressed as a removable drive. By flipping this "Non-Removable Bit", the PC, and any partitioning program will now recognize the USB or SD card as a permanent or fixed drive. I tried a program that was published by Lexmark but I didn't get any results. I did, however, accomplished to partition any USB or SD card with Partition Genius which is a bootable program.

Oh yeah, thanx for your recovery image, highly appreciate it.

SD Card issue help needed

I formated my SD card on my mac as fat32 and now something strange has occured. It seemed to format fine, and I can add things to the card in both OS X and Windows, and Android, however now I cannot format the drive on the windows PC no matter what I try. The disk mounts in windows fine but when I right click and go to format, the SD card umounts and I get the pop-up message:
There is no disk in drive E:
Insert a disk, and then try again.
I think something weird happend when it was formated on the Mac.
My goal was to gain root access, which I've done in the past, but however the Mac disk utility formated the SD card, I cannot get the phone to recognize the DREAIMG.nbh file upon restarting the phone using the rooting method outlined in these forums.
I tryed a few different methods to format the card in windows, including diskpart, and through managment tools. The same thing happens with all methods.
edit: I also tryed formating using the format utility in in Android. It formats fine, but something is still wrong, it will not format in windows.
Any help would be much appreciated.

are you sure its a mac to pc issue? can you add files to the root of the sdcard and such on a mac

Yes, I can add files to the root of the card on the mac.
Whatever the mac's disk utility did during the format, the PC does not like.

Dude same thing happened to me
I found a work-around that. use a an sdcard reader (Usb or the one that comes with the sdcard) I formatted mine that way so I could use it.

Thank you! This worked.

no problem =)

[Q] SD card file size limit 4GB (1080p movies)

Its nice, O2x can play full hd video. i have hdmi cable, full hd screen, but how can i play it, when its not posible to store it on SD card? does anyone have solution to play 1080p videos larger than 4GB on O2x?
-when i format SD card to other FS than fat32, it cant be recognized by phone.
-i havent found any kernel with other fs support on sd card.
-all old questions in other forums end that the phone have small screen resolution and i dont need full hd movies.

use dlna and stream from a pc, i dont think we can have files larger when 4gb on android

it isnt solution of the problem

it's not a problem android can't use files larger when 4gb and where is nothing to do abort it, so dlna is the only solution, or you can use handbrake to make the file smaller

If you use a Linux desktop system (think mac works to) you can format the sd card to ext2. It should make it possible to store the files that's bigger then 4GB. Since Its rather a limit of the fat32 file system then android it self.
I have tested ext2 on Cyanogenmods kernel and works for me. Didn't test the file size limit since I tried with a spare 2GB card, will make my 16GB card to ext2 soon to try.

you have to resize your size of 1080p movies, because the limit of fat32

I did make my 16GB card to ext2 and it mounted an worked perfectly fine. Only problem I found was the lack of ext support in cwm recovery.
Might be able to fix if source code to cwm is available. Since its just the mount line rhat needs to be changed to auto.

It's not an Android limitation but a VFAT filesystem limitation. This filesystem is very old and at that time hard disks were small and so 4GB limit sounded sufficient...
NTFS, HFS+ (Mac), and all linux filesystem (ext2, ext3, ext4, XFS, and so on) can manage files > 4 GB.
The only problem is that if you format your card in Ext4, it won't be recognised directly by Windows (no free driver, I think a commercial product exists). Ext2 and ext3 can be read from Windows (there are free apps to do that), but it won't be as simple as VFAT as you'll have to install this specific program on each computer you plug your phone in. (With Mac non problem as it is Unix based OS).

[Q] HELP SD Problem

Hi guys. So today I created 300mb ext4 partition on my SD card (8GB) with Partition Wizard. I did everything like it was in tutorial, I've got one ext4, 300mb, 4kb clasters and 7700mb FAT32 card. The thing is. After I did it. My PC don't shows me my SD card in "my computer". When I launch Partition Wizard, the drives are still there, but in my PC there is no SD cards. I set it active and gave it a letter (F, but nothing.
After that I inserted other card to my computer and the same thing. My pc don't recognize any SD card, but it recognizes when I launch Partition Wizard.
Can anyone explain me what the hell is happening and how I solve that please?

Windows Problem
HI there,
The problem is that windows is uncapable of reading or writing to superior filesystems than it's own rubbish and unreliable fat32 and ntfs filesystems.
Download any version of linux that you fancy from Distrowatch.org, burn the cd and boot from it.. You may work with it running from the cd and dont even have to install it..
It will let you use your sd card properly.. Youll also have read/write access to your windows disk and files from any major linux live-cd..
I suggest Mint 11 LXDE 64 bit, it comes with everything you need preinstalled including all codecs and flash player..
Youll notice how rubbish windows is if you give it a try.. Your computer will run much faster even running live from the cd.. When installed, it's even faster again..
Did I mention it can't get viruses?
Have fun and good luck,
CtrlAltDel

Thanks, I myself am linux lover. But I can't use it. There is lot of programs I need and Linux does not support them. For example Adobe progs, 3Ds max.
And the last thing that prevents me from using linux is my GPU, I've got two GPUs (hybrid) Intel and nVidia. So when I install linux, it is only intel that I can use. No drivers for nVidia and optimus hybrid system. =(

Filesystem used on external sd card

I'd like to remove my external SD card and use my Linux (RHEL/CentOS) workstation to copy files to and from it. The card has not been encrypted and is 6¤ GB in size.
Unfortunately the workstation did not recognize the file format, Solid Explorer on the tablet does not tell me which file system is used and Googling suggests it may be a special flash file system suitable for SD cards, presumably not available on desktop Linux distributions.
Does anyone have information?

Probably exfat.
Diskinfo will tell you what it is.

Should be FAT or exFAT

Thank you, have downloaded DiskInfo from the Play Store to my phones but not yet to the tablet. I know RHEL/CentOS has drivers for MSDOS (FAT) and vFAT but do not know about exFAT.

It is definitely exfat and it is an exfat flavor that can't be duplicated on Windows according to Microsloth. Although you should be able to read/write the card from a Windows PC do not try to format it on a PC. The M/S exfat format does not handle large filesystem cards.
You can read/write and I think format the card (if needed) from Linux using exfat-fuse. I built it from source the other day, took all of three minutes. Good stuff!
Depending on your package manager you should be able to search on exfat or fuse and find the drivers.
BTW I did some experimenting with card filesystems since the internal memory is supposedly ext4. I formatted a memory card ext3 and the S7 couldn't read it.
Would have been nice to have a standard portable filesystem available instead of having to use something proprietary that google has to pay Microslop for.

Have had no issues formatting 64gb sd cards as exFAT in Windows. I see no reason why it wouldn't be compatible.
It's a Windows format that has been incorporated to work on Samsung Android devices.
As for Google I don't think exfat is yet natively supported on AOSP unless it's been added recently.

You were right, a small SD card used VFAT while a 64 GB card used exFAT. The former can be read natively on RHEL/CentOS and there are third-party drivers for the latter.
Thank you, DiskInfo looks like a very nice utility.
