anyone know how to use it? the disk i want to copy is hooked up but i can't figure out how to run the program properly from the command prompt. i am not sure how to point to the correct drive location thru terminal. any help is appreciated...
 
Running "diskutil list" in the Terminal will give you a list of all the disks attached to your computer. Make a note of the one that corresponds to your game hard drive, e.g. /dev/disk3

I think chdman will take the "/dev/disk#" format as a parameter to specify a physical drive. e.g. ./chdman -createhd mygame.chd /dev/disk3
 
I had to create the CHD in windows. Trying to extract it in Mac and I run this command:
./chdman -extract gt2005.chd /dev/disk0

and i get this output:
chdman - MAME Compressed Hunks of Data (CHD) manager 0.95u6 (Apr 29 2005)
Input file: gt2005.chd
Output file: /dev/disk0
Error opening output file '/dev/disk0'


This is what i have as disks (from diskutil list):
/dev/disk0
#: TYPE NAME SIZE IDENTIFIER
0: FDisk_partition_scheme *250.1 GB disk0
1: DOS_FAT_32 UNTITLED 1 250.1 GB disk0s1
/dev/disk1
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *750.2 GB disk1
1: EFI 209.7 MB disk1s1
2: Apple_HFS Mac OS 749.8 GB disk1s2
/dev/disk2
#: TYPE NAME SIZE IDENTIFIER
0: FDisk_partition_scheme *500.1 GB disk2
1: Apple_HFS External HD 500.1 GB disk2s1


Disk0 is where I want to write. What am I doing wrong?
 
I know this is an old thread but thought someone else may have the same issue. I was having the same issue on a mac, you must unmount the partition in disk utility before running the command, this fixed it for me!
