With HDDRIVER you can exchange data between your Atari and a PC or Mac without any additional software. Memory cards are ideal media for this purpose, but other removable media and hard disk drives can also be used. Exchanging data between the Atari and other platforms has never been this easy! HDDRIVER can even handle the modern UEFI GUID partition tables (GPT).
The screenshot shows the files included in the HDDRIVER distribution displayed on a Windows PC. The medium is a memory card with four TOS/Windows compatible partitions created with HDDRUTIL on the Atari. Windows versions older than Windows 10 have limitations regarding removable media: Only the first partition is recognized, all others are ignored.
With a non-removable medium (hard disk) any version of Windows supports several partitions per drive, like in this case two TOS/Windows compatible FAT32 partitions of about 70 GiB each, which were created with HDDRUTIL. In order to use FAT32 partitions with the Atari MagiC or MiNT have to be installed.
A memory card with four partitions on a Mac. Like with TOS and Windows 10 all partitions are accessible.
There are several ways to exchange data with Linux systems. With most Linux distributions Atari partitions can be mounted directly, so that no special partitioning is required. The mtools software package can also be used to access Atari compatible partitions. Note that the Linux kernel may impose restrictions on the maximum logical sector size of a TOS partition.
HDDRIVER supports partitions which are defined in GUID partition tables, provided that their sector numbers are within the 32 bit range.
GUID types map to MBR types like this:
|GUID Type||Windows/Linux or TOS Type|
|EBD0A0A2-B9E5-4433-87C0-68B6B72699C7||$0E (FAT16 LBA), $0C (FAT32 LBA)|
Optionally all other GUID types can be mapped to the XHDI RAW type.
