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

dvdfs(4)						     Kernel Interfaces Manual							  dvdfs(4)

NAME
dvdfs - The Digital Versatile Disk File System [This feature is not supported in Tru64 UNIX Version 5.0] STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: ISO/ITEC 13346:1995 Optical Storage Technology Association (OSTA) Universal Disk Format (UDF) Specification, "OSTA UDF Compliant Domain", Version 2.00. ISO 9660:1988 Information Processing-Volume and file structure of CD-ROM for information interchange. Refer to the standards(5) reference page for more information about industry standards and associated tags. DESCRIPTION
The Digital Versatile Disk File System enables the reading of disks formatted in the Universal Disk Format (UDF). User data sectors in a DVD-ROM can contain any type of data in any format. However, for Tru64 UNIX support through the dvdfs file system, the OSTA UDF file format standard is mandatory. The file system limit for DVDFS is int cfs_cdfs_mount_limit = 512. Additionally, DVD-ROM standards require that the logical sector size and the logical block (the user data block) size be 2048 bytes. DVD support in the UDF specification includes these levels: DVD-ROM (Read-only): Supports reading of UDF-formated files from DVD-ROM disks. DVD-R (Write-once): Supports the reading of UDF-formated files from a DVD-ROM disk and supports writing, one time, UDF-formated files onto a DVD-ROM disk. DVD-RAM (Rewritable): Supports reading and writing of UDF-formated files from and to a DVD-ROM disk. At this time, the Tru64 UNIX dvdfs file system supports only the DVD-ROM (Read-only) format. See mount(8) for information about mounting and unmounting a dvdfs file system, fstab(4) for information about including dvdfs file system in a system's /etc/fstab file, and disklabel(8) for information about labeling DVD-ROM disks. RELATED INFORMATION
Commands: disklabel(8), mount(8) Files: cdfs(4) fstab(4) delim off dvdfs(4)
