HDINFO is available to order in two versions, HDINFO and HDINFO Plus. Both versions contain the features listed including the IDEINFO program to test your BIOS for 48-bit LBA compatibility. The difference between the two versions is that HDINFO Plus also includes an ISO image of the IDEINFO program. You can use this ISO image with a CD burning application to create a bootable CD. If your system has a diskette drive, you can use standard HDINFO. If your system does not have a diskette drive but does have a CDROM or DVD, you should order HDINFO Plus.
