Full Discussion: dd command
Operating Systems Solaris dd command Post 99977 by zazzybob on Wednesday 22nd of February 2006 07:29:38 PM
Old 02-22-2006
I dd from CD-ROM and DVD quite often to make iso images for mounting under VMWare ESX server. I always use a bs=512 in the dd command when creating the ISOs. I've never timed it, but also never been disappointed with performance - most data I've ever dd'd from optical media is around 1.4Gb.

Cheers

HOME(8) 						      System Manager's Manual							   HOME(8)

NAME
home, 40meg, 80meg, personalize, update, Disclabel - administration for local file systems SYNOPSIS
gnot/home gnot/personalize gnot/update magnum/home magnum/personalize magnum/update pc/40meg pc/80meg pc/personalize pc/update nextstation/home nextstation/update DESCRIPTION
These programs help maintain a file system on a local disk for a private machine. Home partitions a disk, copies the appropriate kernel to the disk, and makes a new file system on the disk. To do this, it overwrites the vendor-supplied software on the disk with a copy of Plan 9. 40meg, 80meg, and 100meg configure disks and make file systems for disks of the appropriate size. Update copies the current kernel to the disk and updates files on the local file system. It only updates those files put there by the home program. Personalize removes the contents of the /usr directory on the local disk and copies a minimal set of files for the user who runs the com- mand. The file /rc/bin/nextstation/Disclabel, despite its name, is not an rc(1) script. It contains the second stage bootstrap program for Nextstations booting from local disk. Before booting a Plan 9 Nextstation from disk, it should be installed in the partition /dev/hd1label; this is normally done by nexstation/home. FILES
/lib/proto/portproto Mkfs prototype files for magnum/home, magnum/update, gnot/home, and gnot/update. /lib/proto/386proto Mkfs prototype files for pc/40meg, pc/80meg, and pc/update. SOURCE
