Try out the demo version and see for yourself that HDDRIVER offers unique features and higher speed compared to other drivers. The demo version includes a README file with installation information. In a nutshell: Launch HDDRIVER, then launch HDDRUTIL, and install (or update) HDDRIVER by double clicking drive C:.
These are the most important restrictions of the demo version:
With respect to the supported hardware there are no differences compared to the full version. If the demo version does not work with your hardware, the full version also will not.
Using the ZIP archive is the recommended way of installing the HDDRIVER demo version. Simply unzip the archive and follow the instructions in the README file.
If you do not have any means to transfer the ZIP archive to your Atari, drive images with a pre-installed demo version are offered. (There are two images because on IDE and SATA drives the Atari saves data with a byte order different from the one used with ACSI/SCSI drives.) These images contain a small partition with a bootable demo version and all files included in the ZIP archive.
With Linux or macOS you can write the image suitable for your hardware to a memory card or hard disk drive with the command line tool dd, and then boot your Atari from this drive. The required command is
dd if=PATH_TO_IMAGE_FILE of=PATH_TO_DRIVE_RAW_DEVICEPlease refer to the dd manpage for details. For Windows the Win32 Disk Imager can be used.
