[SOLVED]is there a 4gb cap?

otacon · 2008-12-10 00:08:41

Move error.

I made a copy of a disc by using the dd comand in terminal and made an iso.

this iso is 7.5gbs because the dvd was dual layer.

I am trying to move this iso onto my external hard drive but at 4gb it comes up with an error.
my 3.7gb iso worked but not the 7.5.

I am using KDE if that is of anyhelp. My folder manager is Dolphin.

anyone know if it could be a cap of 4gb transfer or something?

There is a 4gb file size limit on fat32. Is that what you have?

otacon · 2008-12-10 00:24:53

I am running Arch64.
on ext3

isn't fat32 the old windows filesystem before nfst or something like that.

oh maybe the external is. I don't know. It is a 40gb external hard drive.

how do I find out and fix it?

ozar · 2008-12-10 00:31:08

The external is probably running on fat32. Run this to find out:

fdisk -l

otacon · 2008-12-10 00:37:27

[otacon@remcycle ~]$ fdisk -l
Cannot open /dev/sda
Cannot open /dev/sdb
Cannot open /dev/sdd

Disk /dev/sde: 40.0 GB, 40007761920 bytes
255 heads, 63 sectors/track, 4864 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xab8c8f13

Device Boot Start End Blocks Id System
/dev/sde1 1 4864 39070048+ b W95 FAT32

yep it is fat32
what program can I use to reformat it in a different format and what format should I use?

ozar · 2008-12-10 00:43:32

If you want "easy to use", I'd suggest using the PartedMagic LiveCD:

http://www.partedmagic.com

It's a quick download and burn to cd, and is about as easy as it can get.

You could use ext3 or ntfs if you want to get around the 4gb barrier.

Statix · 2008-12-10 01:33:27

If you want to simply erase everything on the drive and reformat it just run:

mke2fs -j /dev/sde1

That'll put ext3 on it.

Make sure that /dev/sde1 is the actual device you want to format first by doing a fdisk -l

I know that you can also convert it to ntfs using a windows conversion program. You won't lose what's on it that way. I'm don't know how though.

From XP or Vista (In the great cmd terminal!): convert drive letter: /fs:ntfs

otacon · 2008-12-10 01:55:08

so I just used gparted to reformat it as ntfs but now I don't have permission to edit anything on the drive.
wierd.

I don't know what I am doing wrong.
I just don't have permission to make or delete anything from it.

I am in the storage group so I don't have a clue what is going on.

Can you guys help me?

ozar · 2008-12-10 02:14:44

To write to ntfs from linux, you'll need to install the ntfs-3g package.

If you don't need ntfs, ext3 is probably the better choice.

Edit: here's the link for setting up ntfs-3g should you go that route:

ok I used
mke2fs -j /dev/sdc
and that worked without the permission problem.
the bad thing is this is the bridge between my mac laptop and my desktop.
so hope mac recognizes it. If not I am back to square one. Guess I am removing gparted.

otacon · 2008-12-10 02:22:56

I mean I will try your wiki if it doesn't work

ok this actually worked for me.
thank you.

I used ntfs to mount the device and edited fstab to allow me to have permission to the mount.

It wasn't a permission problem

FAT-32 was the old partition format used by Windows, correct. It does have a limit of max 4GB per file. It's also one of the most universal formats around today - Linux, *BSD, Mac, Win... they all support it out of the box. NTFS is the new Windows partition format, no such limit. But, only Windows supports it natively. You couldn't use it in Linux because Linux needs an add-on to support it, ntfs-3g. Google it for more info. Mac would need the same type of thing I believe. So, there's no reason to use NTFS. ext3, which is what you formatted the drive to now, is also a modern format, but is only supported natively by Linux and maybe some other *nixes. Mac uses hfs I believe, which is not compatible with Linux... maybe through something like ntfs-3g...

Your best bet IMO would be to format to FAT32, and just split the file into < 4GB pieces. How to split the file? Simple, use the split app. Consult Google and the split manual 'man split' for more info. There's probably/definitely GUI apps too. Compressing the ISO with tar would save space and let you split all in one step, too.

(Googled) Apparently, ext2fsx is a set of tools for Mac to mount ext2/3. That would also work. Google for more info, again.

EDIT: Apparently, Mac FS support is in the Linux kernel. Just format the hard drive with your Mac and you're good to go.

It wouldn't be practical for me to use Fat32

You see the only system that doesn't support it natively is linux and as long as you don't need to modify it then you can always see ntfs natively.

1.My leopard recognized it and let me modify the external as ntfs.
2. native to windows
3. linux has to be modified and configured for almost everything so why not ntfs?

so the choice is to break down files into smaller ones so I can use Fat32 everytime I need to or download and configure ntfs once.

Linux is the only one behind right now. so like everything else known to linux it is all just configure configure configure.

PS:
the problem wasn't just with ntfs. Everything I used in gparted was not able to be modified. it wasn't untill I used plain bash to make the ext3 version that it started to work.

My conclusion is that I did something wrong in gparted or didn't set it up correctly

I wouldn't say linux generally is behind on ntfs really... It is just a case of install one program to read it if you format it correctly.
And IIRC Ubuntu now has ntfs out of the box

Is not supporting windows' fs really being behind anyway?
