Hard Disk Drives, Removable Media Drives, SSDs and Memory Cards

Besides hard disk drives and SSDs HDDRIVER supports removable media drives, e.g. drives by Syquest, ZIP, JAZ, DVD+RW and DVD-RAM drives. Media changes are detected automatically and reliably. Media can be ejected by a keystroke (depending on the desktop being used).
HDDRIVER provides ideal support for memory cards like SD and CF, which are an inexpensive and noiseless alternative to hard disk drives.


In terms of compatibility HDDRIVER sets standards. Drives or memory cards with a capacity of up to 2048 GiB (2 TiB) are supported. (With the ST/STE in order to use more than the first GiB of SCSI drives a suitable host adapter is required.) HDDRIVER is fully backwards compatible with Atari's hard disk driver AHDI and therefore guarantees highest compatibility with other applications.

Data Exchange with PCs and Macs

With HDDRIVER it is child's play to exchange data with PCs (Windows XP and newer or Linux) and Macs. There is no need for any additional software. In combination with MagiC or MiNT exchanging data even works with long filenames (FAT32). Additionally, with MiNT and HDDRIVER it is possible to access Linux partitions (ext2).

Backups and Copying

With the HDDRUTIL tool storage media can completely or partially be copied, e.g. in order to create backups or to exchange data. With many optical drives storing data on DVD-RAM, DVD+RW and BD-RE media in particular for backups is supported. Furthermore, complete media or single partitions can be saved as image files or loaded from image files.

Data Security

For HDDRIVER data security plays an important role. The data transferred are optionally verified in order to detect errors when writing data. Selected partitions can be write-protected, which is a good protection against viruses and accidential changes. Important areas of a drive (root sector and boot sectors) can separately be protected against unintentional changes. If a device supports a self-test, it can be triggered by a mouse-click.


HDDRIVER is more than just a driver. Several tools with a modern graphical user interface complete the HDDRIVER distribution. Media can be formatted, devices can be configured, and self-tests can be executed. Drives can be parked and media ejected, the password-based read/write protection of ZIP/JAZ drives can be configured, and much more. Besides the HDDRUTIL tool an ACC and CPX modules provide for conveniently controlling numerous settings, without you having to be a hard disk wizard.

SCSI Driver and XHDI Interface

Unified access to peripherals is realized by the SCSI Driver integrated in HDDRIVER. This important software interface for Atari compatibles, which is not limited to SCSI devices only, is used by a range of other drivers and applications. For IDE drives HDDRIVER's SCSI Driver emulates the most important SCSI commands. This enables any application to access IDE, ATAPI and SATA drives as if they were SCSI devices. Additionally, HDDRIVER supports the complete range of functions defined by the widespread XHDI standard.
Applications can access many driver functions by using these two well-documented and standardized software interfaces.

Other Highlights

When running MagiC, MiNT or Big-DOS in combination with HDDRIVER you have access to more than the usual 16 drives. With non-blocking data transfers for drives connected to the ACSI or SCSI bus you gain speed when using HDDRIVER with MagiC because you can work with your Atari while data are being transferred in the background.
Features like booting from any partition, SCSI initiator identification and bus arbitration (for a maximum of compatibility with the SCSI standard), automatically parking drives etc. can be taken for granted with HDDRIVER.

User Support and Documentation

The HDDRIVER distribution includes a detailed printed English or German manual. In case of problems or questions users get support by the FAQ, by email or in the HDDRIVER forum.
