I'm trying to duplicate a usb drive I installed debian. To do so, I'm using the dd function, and I'm actually doing it from the Mac OS X command line.
dd bs=512 if=/dev/disk3 conv=sync,noerror of= ./usb_debian.img
The final code and output:
dd bs=512 if=/dev/disk3 conv=sync,noerror of=usb_debian.img 1981440+0 records in 1981440+0 records out 1014497280 bytes transferred in 710.232612 secs (1428401 bytes/sec)
AWESOME! I just transferred the image to a new, different USB stick, plugged it into an HP t5135, and it booted! That rocks.
