FAT Drive Truncating Files to 4GB

[NextGenSeq]

I am beginning to archive old data and have a 2TB USB FAT formatted drive for this purpose.

However, any file that is larger than 4GB is truncated to 4GB. Apparently FAT drives won't copy files larger than this.

I can compress the files and copy them but soon even the compressed data files will be larger than 4GB.

Is there an easy solution around this?

(Note I can't reformat to NTFS since the data is on a Red Hat computer and they don't support NTFS).

Do you plan to use the drive on a non-linux/unix-variant system? Otherwise just format with a filesystem supported by linux, e.g. ext3.

Ideally it will be able to be mount on Windows computers also.

NTFS is an option, as long as you're able to run ntfs-3g on linux (which is pretty stable).
BTW, FAT capabilities are well known, to me it's a deprecated file system, absolutely unsuitable for modern data throughput. Compressing is not an option, you will lose a lot of time for a workaround.

You can get various drivers that claim to be able to mount or browse ext2/ext3 partitions on Windows:

http://www.ext2fsd.com/

http://www.fs-driver.org/index.html

Hopefully at least one of them would work for you.

Alternatively, you could use the unix 'split' command to break the big files into chunks on the FAT partition.

Thanks I'll look into drivers for mounting ext2/ext3 on windows.

I may be mistaken but most USB thumb drives are also FAT formatted aren't they?

I had this same problem with them.

Unfortunately yes...

I've offered an additional response, suggesting NTFS and FileSpanning options.
