This section describes a tutorial on how to get summary information of a CD-ROM with 'isoinfo' tool.

One of the tools included in the cdrtools package is called "isoinfo", which is a great tool to perform analysis an ISO 9660 file system on a CD-ROM. "isoinfo" supports the following options:

C:\>\local\cdrtools\isoinfo -help

  -debug      Print additional debug info
  -d          Print information from the primary volume descriptor

  -j charset  Use charset to display Joliet file names

I tried to use "isoinfo" to display information from the primary volume descriptor on a CD contains device drivers for a Dell monitor

C:\>\local\cdrtools\isoinfo dev=0,0,0 -d
CD-ROM is in ISO 9660 format
System id:
Volume id: ____
Volume set id:
Publisher id:
Data preparer id:
Application id: NERO - BURNING ROM
Copyright File id:
Abstract File id:
Bibliographic File id:
Volume set size is: 1
Volume set sequence number is: 1
Logical block size is: 2048
Volume size is: 33034
Joliet with UCS level 3 found
NO Rock Ridge present

The output is very nice. It tells me that:

The CD drive is located at "dev=0,0,0", the first device on the first SCSI bus.
This CD does have data stored in ISO 9660 format
This CD uses the CD-ROM Mode 1 standard, because the sector size is 2048 bytes.
The data size on the CD is about 33,034 * 2,048 bytes = 67,653,632 bytes. This matches exactly what Window Explorer reports on this CD.
