Be careful. You’re creating a FreeBSD boot image using Windows. It’s sometimes difficult to see which hard disk you’re writing to. See here:

Download dd for Windows here: chrysocome.net – download. I chose beta 0.6.3. Unzip it, and take a look at the options:
dd [bs=SIZE] [count=BLOCKS] [if=FILE] [of=FILE] [seek=BLOCKS] [skip=BLOCKS] [–s SIZE and BLOCKS may have one of the following suffix:
k = 1024
M = 1048576
G = 1073741824
default block size (bs) is 512 bytes
skip specifies the starting offset of the input file (if)
seek specifies the starting offset of the output file (of)
I had to run CMD and then dd as administrator (on Windows 7). Unless I did that, I couldn’t see the NT Block Device Objects. When I ran as administrator, i got the following (in addition to other outputs):
NT Block Device Objects

Then, I ran the dd command. I got a file permission error problem. I went over to the Windows volume manager and formatted the drive I was interested in. Windows formatting of the drive failed, too. It created a partition with a size of 24MB. After that, though, I could run dd:
D:\Users\Poojan\Downloads\dd-0.6beta3>dd bs=10240 if=..\8.1-RELEASE-amd64-all\FreeBSD-8.1-RELEASE-amd64-memstick.img of=\\?\Device\H
arddisk3\Partition0 –progress
rawwrite dd for windows version 0.6beta3.

It has been running for quite a while. It’s up to a count of 470,000,000 right now.
After about 30 minutes, it’s finally done:
D:\Users\Poojan\Downloads\dd-0.6beta3>dd bs=10240 if=..\8.1-RELEASE-amd64-all\FreeBSD-8.1-RELEASE-amd64-memstick.img of=\\?\Device\H
