Description michaelg 1999-09-23 18:35:44 UTC 
When reading large files > 2Gb it works fine, but writing
gives an error when using SEEK.

E.g. a 4 Gb disk on /dev/hdc:

# dd if=/dev/zero of=/dev/hdc bs=1M seek=4000 count=1

gives an invalid arguement error.

Thanks
Michael

This can't be fixed until 64-bit file support is integrated into the standard
Linux kernel due to dd semantics (we need ftruncate64())
