hi, I've been trying to resize a DVD image with hdiutil. It showld work but it doesnt.
I do:

hdiutil resize -size 1g disk1.dmg
hdiutil resize -size 1g -partitionOnly disk1.dmg
hdiutil resize -size 1g -imageOnly disk1.dmg

and I get this error every time,

hdiutil: resize request is below minimum size allowed.
hdiutil: resize: failed. Invalid argument (22)

the image has read/write privileges, and is not mounted. Its also empty (I deleted all the contents, I just need the bootsector).
Im missing something.....

this works perfectly fine for me :

~ : hdiutil resize -size 40M ~/Desktop/new4test.dmg
~ : ll ~/Desktop/new4test.dmg
-rw-r--r-- 1 caytam caytam 41980928 Jul 30 07:24 ~/Desktop/new4test.dmg
~ : hdiutil resize -size 100M ~/Desktop/new4test.dmg
~ : ll ~/Desktop/new4test.dmg
-rw-r--r-- 1 caytam caytam 104895488 Jul 30 07:25 ~/Desktop/new4test.dmg

your problem should be elsewhere.

Try to have a look to this i got different problem a bit time ago:

if you just need a boot sector
why not use dd and the i386s(standalone/i386) create one by yourself
