I recently tried using dd to transfer a binary image to floppy. It was the Linux root disk image, color.gz. Basically, dd works ok with non-gzipped files, but with files in gzip format, it chokes: root@lc186 floppies# dd if=color.gz of=/dev/rfd0 dd: /dev/rfd0: Invalid argument 2453+1 records in 2453+0 records out 1255936 bytes transferred in 42.665771 secs (29437 bytes/sec) Notice the line that says: 2453+1 records in ^^^^^^ For some reason, it is offsetting to 1 before writing to disk. Rawrite.exe does this correctly. I tried with net.i, and it gave me no problems: root@lc186 floppies# dd if=net.i of=/dev/rfd0 2156+0 records in 2156+0 records out 1103872 bytes transferred in 39.172698 secs (28180 bytes/sec) I tried skip=0, but that didn't work. Apparently, dd has some limitations with what kinds of files you can transfer to floppies. I downloaded the files in binary format, so there's no problems there. -- - Donn To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
