Overview
Intelligent Driver with Tools

When it is about mass storage and the Atari HDDRIVER is the first choice. Only HDDRIVER and its tools fully support all standards for the Atari in the latest versions and thus offer maximum compatibility. Be it TOS, MiNT or MagiC, be it ACSI, SCSI, IDE, ATAPI, SATA or even USB (the latter with third-party modules). HDDRIVER is the ideal driver also for SCSI2Pi, PiSCSI or BlueSCSI. For Atari emulators HDDRIVER even offers special functions. The software automatically detects properties of TOS versions and devices and intelligently adapts to them. Fully exploit the capabilities of your Atari, not only with respect to drive capacities, number of partitions or partition sizes! When switching from another driver to HDDRIVER re-partitioning is not required, i.e. no data are lost.
The HDDRIVER software package offers much more than just a driver. It includes easy to use maintenance tools with a user-friendly interface. Formatting, partitioning, copying, erasing, configuring, testing, performance tuning and much more - no problem! There are also numerous add-ons and third-party programs which all profit from HDDRIVER.

Support for numerous Device Types

Besides hard drives, DOMs and SSDs HDDRIVER supports removable media drives, e.g. Syquest, ZIP, JAZ, MODs, DVD+RW, DVD-RAM, GigaFile or UltraSatan and memory cards. USB devices are supported by third-party HDDRIVER modules.
On the part of HDDRIVER there is no upper limit for the capacity of mass storage media. With the ACSI bus in order to use more than 1 GiB of capacity an ICD compatible host adapter or an ICD compatible device like the GigaFile or the UltraSatan are required. TOS, MagiC and MiNT limit the usable capacity to 2 TiB (2048 GiB). Tools like HDDRUTIL or DISKUS support 64 bit sector numbers and thus can access even larger media.
Rewritable optical media (DVD-RAM, DVD+RW, BD-RE) can be used for storing data on a regular TOS filesystem. Simply use the DVD writer of your old PC as a backup drive for your Atari data!

Fast and easy Data Exchange with PCs and Macs

With HDDRIVER it is child's play to exchange data using removable media/memory cards, without additional software or inconvenient cable connections. In combination with MagiC or MiNT this even works with long filenames and very big partitions (FAT32). Additionally, with MiNT and HDDRIVER you can access Linux partitions (EXT2). HDDRIVER supports both the legacy MBR (Master Boot Record) and the modern UEFI GUID Partition Table (GPT) partitioning scheme.

High Speed

HDDRIVER is entirely coded in assembler and therefore fast and compact. ACSI, IDE/SATA drives and memory cards profit from settings for extra fast data transfers. Owners of a Thunder IDE interface can boot HDDRIVER into TT-RAM, which considerably boosts the IDE transfer rate and saves precious ST-RAM. Optional blitter support also results in a higher IDE throughput. With the multitasking operating system MagiC SCSI and ACSI transfers can run in the background.

Fast Booting

AUTO folder programs like FOLDRxxx, CACHExxx, JARxxx or SCSIDRV are obsolete, which speeds up booting and keeps the AUTO folder clean. The functionality of these programs is included in HDDRIVER. Because HDDRIVER can execute the AUTO folder and accessories from any partition by pressing a key, a boot selector is often unnecessary.

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 accidental 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 simply a mouse-click.

Professional Tools

HDDRIVER is more than just a driver. A set of sophisticated tools with a graphical user interface completes the distribution. Media can be formatted, devices can be configured, and self-tests can be executed. Drives can be parked (automatically) and media ejected, the read/write protection of ZIP/JAZ drives can be configured. 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 with TOS filesystems is supported. Complete media or single partitions can be saved as image files or loaded from image files, and much more.
An accessory and CPX modules allow to conveniently manage numerous settings, without you having to be a hard drive wizard.

Software Interfaces

HDDRIVER supports the SCSI Driver interface for a unified access to peripherals. This open software interface is not limited to SCSI devices and is used by a range of other drivers and applications. Optical SATA drives innately use SCSI commands anyway, for IDE and SATA hard drives HDDRIVER emulates them. This means that any application can access IDE, ATAPI and SATA drives as if they were SCSI devices. HDDRIVER's SCSI Driver supports 64 bit sector numbers, so that drives > 2 TiB (2048 GiB) can be addressed with their full capacity. Additionally, HDDRIVER supports the complete set of functions defined by the XHDI standard.

Other Highlights

With MagiC, MiNT or Big-DOS and HDDRIVER up to 31 drives and big partitions can be managed. Single partitions can be mapped to the drives A: and B:.
Features like SCSI initiator identification and bus arbitration (for a maximum of compatibility with the SCSI standard) can be taken for granted with HDDRIVER.

User Support and Documentation

In contrast to other drivers HDDRIVER is actively maintained. The scope of delivery includes a detailed manual as PDF. Users get support by the FAQ, by email or in the HDDRIVER forum. With the Hddriver News app for Android you stay up to date.
