Splitting large files into external FAT32 HD

[Tito]

Hello people:
I am new to Linux. I posted the message "Saving a large container from a crashed WinXP to external HD". My problem was that the external HD connected thru the USB port was NTFS and i could not make Captive NTFS accept the container. I changed the filesystem in the external HD using QTParted to FAT32. Then i susccessfully copied one 250 mb container simply using the right-click copy and paste. However, when i try the same strategy with the large 4 GB container the process starts fine but then at about 2 GB the writing onto the external HD is stopped and i receive a message like "Process died unexpectedly" (it happened twice) I thought i could split and rejoin the 4 GB container using the split and cat commands but i do not have enough disk space in the local partition (hda1). I do have space in the external HD (sda1 partition) so my question is if there is any simple modification of the split command

split -b 1000m filename filename

to put the split pieces into sda1 rather than hda1. I also want to join the pieces in the sda1 partition before connecting the external HD to another computer that will receive the container.

cat filenamead >> filenameaa

So how do i identify the sda1 partition in the cat command?
Thanks for your help.

With split, split -b 1000m filename /mnt/sda1/filename

basicly the same for cat.

Thanks. In the external HD i have a little less than 8 GB so to rejoin
the parts into the whole container, which is 4GB, i need to delete the parts as they are being assembled. How do i modify the cat command to do just that?

I am not absolutely certain, but my recollection is there is a 2GB max on fat32 file sizes. You won't be able to cat the pieces together except on a ext2 or a NTFS drive. I went a few rounds with this issue a year or two ago and ended up with the large file on an ext2 file and a driver to mount the ext2 file in Win2K. I was trying to get a large drive image burned to a DVD.

You seem to be correct sir. I made a little research and also read messages in LinuxQuestions.org and apparently there is a 2GB limit in FAT32 (though there seems to be a patch).
Apart from the road you took, maybe i can copy the parts into WinXP and then re-assemble them using some MS-DOS command?

In the Root Shell i wrote:

split -b 1000m mnt/hda1/filename.xxx /mnt/sda1/filename

and the system responded

split: mnt/hda1/filename.xxx: No such file or directory

However, i know it is there, i can see it with Konqueror. What could
be wrong with my command?

use the command line copy command. I think

c:\> copy /b part1+ /b part2 joinedFile

Check with the help to see proper/correct syntax.

copy /?

Thanks. In fact the split command did work so please disregard my previous post. I moved the parts from the external FAT32 HD into a working WinXP machine and joined them with
copy \b partaa+partab+...+partae joined.xxx
Now i have to open the container to see that everything is fine inside.
It looks like i have completed my rescue mission.
Thanks to Koppix and to you guys!

Next mission: To reinstall WinXP in the Compaq machine and also Knoppix-Debian to have a dual boot system!

There is a 2gb limit on Fat32 with knoppix, though my winxp can go up to 4gb.

Don't keep us in suspense. Did it work?
