CD-ROM serial number

NTDEV
1

Hello!

I need my driver (installed as filter driver under CDFS) identify cd-rom
disks, so i need something like “cd-rom disk serial number”. How it can be
done? Can i get this number somethere or i need compute it myself (from some
cd-rom disk content)?

use system + volume ids in the 16th sector of a data cd, or maybe the
better way is to count hash for a full toc of a cd. the second method
will work on any cds. for example cddb uses toc (not a full toc) to
identify cds.

You can also use the UPC code for the CD.

Couldn’t the Vendor Unique Serial Number from IDENTIFY_DATA
be used to globally identify the CD-ROM device.

typedef struct _IDENTIFY_DATA {
USHORT GeneralConfiguration; // 00 00
USHORT NumCylinders; // 02 1
USHORT Reserved1; // 04 2
USHORT NumHeads; // 06 3
USHORT UnformattedBytesPerTrack; // 08 4
USHORT UnformattedBytesPerSector; // 0A 5
USHORT NumSectorsPerTrack; // 0C 6
USHORT VendorUnique1[3]; // 0E 7-9
UCHAR SerialNumber[20]; // 14 10-19

I suspect that media catalog number isn’t a wide-spread Q-mode. I’ve
checked all the CDs I have recently and could not find a CD with that
number. All the tracks had mode-1 Q-channel encoding.

toc is not enough unique and can not be used for strong CD
identification. Even cdfs does not use it for data CD.
Most simple and way that much stronger than toc hash is using of
Vpb->SerialNumber. You need calc nothing just use Vpb.
Cdfs calcs this field differently for data and audio CDs.
For data SerialNumber is used checksum of primary volume descriptor, for
audio - checksum of toc because audion CDs have many tracks and toc
can be considered as unique.
Search cdfs driver sources for functions: CdTocSerial, CdSerial32.
