I'm trying to copy a data DVD (Debian Sarge actually)using the command: dd if=/dev/hdb of=debiansarge.iso
and it is failing with the following error: File size limit exceeded
df gives this info for the partition usage: /dev/hda2 19533504 4194320 15339184 22% /mnt/unknownLinux it's a fat32 partition, unused except for my trying to create this file.

Some day, I would dearly love if someone could explain to my why anyone would write any software that uses a signed integer for something that can never be negative -- any takers? :-)

I just knew that it had to be a very practical reason :-)

I don't think that's the only limitation, a signed int. It has to be something else.
In dos, negative numbers were used sometimes as the resturn code of functions (instead of the expected size) to indicate the error code. I can't certify if that was the case here, though.

yup
... and which negative number depended upon which error... typically a non-zero return code is a failure... and the positive ints would be the size... so the negatives would be the rc values.
I agree though with a previous post that it has to be something other than the int... like ok, why in the world would anyone want to use something other than an unsigned long...

Thanks Andreas. I had thougth it might be something wrong with the command itself.

FAT32 has a max filesize of 2GB.

FAT16 has a max filesize of < 2GB. FAT32 has a max filesize of < 4GB

Oops, you're correct. He's still going to run into a size problem, though, as the sarge DVD iso is 4.4GB.

He's beginning to wish he'd never set that partition up as an exchange media between XP and Linux.

there is a very good ext2/3 native driver for XP, and it's OSS, better use this

Fantastic!
:-)
as a side note, this afternoon I had to pull out the usb drive from my linux box and did this on the fast way (no sync stop before)
I couldn't open the ext3 partition with XP.
I connected the disk to the linux, unconnected cleanly and XP did open the volume.
so linux is still better the ext2ifs driver is very good

I'm curious if Captain Nemo would have seen it. The demo is free.

I guess it is too late to find out.

I was going to ask about that. What handles when you write to an ext3 in Windows (obviously mounted as ext2) and then go back to linux? Does it just update the journal?

One of the primary purposes of a journal is to make the mounting of a dirty filesystem happen much faster.
In general, a filesystem journal is flushed empty every time you cleanly unmount the filesystem.
So Linux can treat an EXT3 filesystem as journaled, but when it is unmounted it effectively becomes a EXT2 filesystem with an extraneous empty journal. I would expect Windows EXT2 drivers to work in pure EXT2 mode and totally ignore the journal.
Then when Linux mounts it again, it goes back to EXT3 mode and starts filling up the journal again. Then flushes it on unmount.
Hopefully if you have power-outage etc. and end up with a "dirty" ext3 filesystem, the Windows EXT2 driver would see that and not attempt to access the partition until the drive was mounted under linux and the journal replayed.

may be it's a bit different, the old (one year) version of etx2ifs didn't accept ext3 at all, but did accept ext2
Hopefully if you have power-outage etc. and end up with a "dirty" ext3 filesystem, the Windows EXT2 driver would see that and not attempt to access the partition until the drive was mounted under linux and the journal replayed.
probably. Hopefully sometime the ext2ifs will be able to replay the journal, an usb drive is prone to such problems

There are more things in ext3 that just a journal, there are more differences. Some new attributes and directory data and such, the format is not the same than ext2.

Sorry but there's no way in Puce that I'm letting windows have access to any of my linux partitions. I do appreciate the suggestion though, I thought about it and decided that I could not trust Windows with sensitive info.

I have no double boot machine, the ext3 partition is on a "shuttle" usb drive, never any sensitive data on it...
but, for example, I use dvgrab to dl the video from my camcorder but I have no video editing program working on my linux computers and do the editing on win (not glad of this :-).
the data being 12Gb for an hour, the usb drive is far the best system to go from a system to the other
