I've been reading on the Windows filesystems recently, so here is the quick answer: The serial number is contained in DOS/Windows partition's boot block, 8 bytes at offset 0x48. For the label you have to parse the DOS/Windows filseystem format. On FAT it's the name of the file in the root directory with the special attribute (VOL or LABEL - something like this, can't remember now). On NTFS it's stored I think as the attribute $VOLUME_NAME of the system file $Volume contained in the inode 3 of the Master File Table. -SB _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
