This is NOT a dd problem. I have been trying to write large files to a vfat
filesystem. This is definitely a bug with the kernel. I have had the seg
fault. Try running the program again, but look at your console. It think
that it will result in a kernel bug statement.I think that mine said it was
in File.c:89 .
Nathan
P.S. I was trying to capture atm data on the partition. The code I am using
works great with an ext2fs partition, but the vfat dies at exactly the same
place.

SUMMARY
Segmentation fault occurs when dd'ing entire drive (9.x GB) to a vfat partition.
************************************************************************************
FULL DESCRIPTION
When using the following command
dd if=/dev/had of=/mnt/win/image.out bs=1048576
A segmentation fault occurs when image.out reaches 4294963200 bytes. The partition /mnt/win is a vfat partition which is approximately 13GB. This partition was created with Windows 98 FDISK.
This problem is repeatble on my system.
************************************************************************************
KEYWORDS- large file, vfat, 4GB 4 GB,
************************************************************************************
SHELL SCRIPT TO DUPLICATE THE PROBLEM
mount -t vfat /dev/hdb6 /mnt/win # was used to mount the 13.x GB partition.
dd if=/dev/had of=/mnt/win/image.out bs=1048576

/mnt/win/image.out was exactly 4294963200 bytes long, when the segmentation fault occurred. I expect the next write to that file would exceed the 4.xGB file limitation in vfat filesystems. Still- the kernel should handle this gracefully.
