• HDDRIVER: A potential bug when interacting with SCSI Drivers for bus IDs > 2 (i.e. for other buses than Atari/Milan ACSI/SCSI/IDE) has been fixed. In particular the SCSI Driver for Hatari and ARAnyM was affected.

Upgrading version 12.x to 12.6 is at no charge. For HDDRIVER 12.6 there is a new demo version. There is also an updated IDE_INFO tool with support for the SD slot of both the MegaST and the VME version of the ATW800/2, just like with HDDRIVER 12.6. In the HDDRIVER forum there are ATW800/2 hints and an ATW800/2 FAQ.

• Manual: The download of the full version includes the up to date English and German manual as a PDF file.
• HDDRIVER: The SCSI emulation for IDE/SATA drives/memory cards supports all mandatory commands of the SBC-4 specification (SCSI Block Commands).
• HDDRIVER: With TT and Falcon SCSI the SCSI Driver supports 32 LUNs (sub-units).
• HDDRIVER: The code for initializing the PMMU of the Afterburner040 has been extracted into an external program for the AUTO folder and an HDDRIVER module, resp. The README file in the FIXES/AB040MMU folder provides more information.
• HDDRIVER: AB040FIX (FIXES folder) was renamed to ALTRAMFX. It is required for Falcons with Alternate RAM (Afterburner040, DFB1, CT*) in order to use SCSI peripherals. The README file in the FIXES/ALTRAMFX folder provides more information.
• HDDRIVER: The Medusa Txx hardware is no longer supported. The Hades is not affected.
• HDDRIVER: Fixed a bug in the LBA-48 access mode, which is used with IDE/SATA drives > 128 GiB.
• HDDRIVER: Extended support of GUID Partition Tables (GPT).
• HDDRIVER: Timeout adjustment for devices with very low transfer rates.
• HDDRIVER: Support for the SD slot of the ATW800/2 also for the VME version. To use the SD slot with the VME version from the first batch, the latest ATW800/2 firmware and a small hardware patch are required. The second batch does not require any modification. The ATW800/2 team has successfully tested both the MegaST and the VME version with HDDRIVER 12.6. The SD slot functionality in both versions is identical, but TOS can only boot from the SD slot of the MegaST version. In the HDDRIVER forum there are ATW800/2 hints and an ATW800/2 FAQ.
• HDDRIVER: If no LUNs are enabled when configuring a device with "Devices and Partitions", the SCSI Driver integrated in HDDRIVER manages the device, but no partitions are created. This is useful when cloning drives/memory cards, for instance.
• HDDRIVER: HDDRIVER at startup does not probe anymore for ACSI/SCSI/IDE hardware when the respective buses are already managed by an existing SCSI Driver. This further improves the hardware independence.
• HDDRIVER: Extensive optimizations.
• HDDRUTIL: The device check uses an improved/optimized query of LUNs and now also detects non-consecutive LUNs.
• HDDRUTIL: The new function "Drive->Clear Data" clears the FATs and the root directory of a partition. This is equivalent to deleting all files, but is much faster.
• HDDRUTIL: "Edit Partitions" supports changing the boot mask bit. Together with an explicit boot preference (TOS or TT SVR4) this mask determines which operating system is booted by default. Only the values $00 (not bootable, $80 (bootable TOS) and $40 (bootable TT SVR4) were specified by Atari.
• HDDRUTIL: The bus information displays whether a SCSI Driver supports 32 LUNs for a bus.
• HDDRUTIL: Depending on the bus features the device check now checks for up to 32 LUNs.
• HDDRUTIL: The function "Test Sectors" was renamed to "Read Test" because there is now also a write test for the data of a medium. This test first reads the sectors and then writes them back. Nevertheless it is recommended to save the data before a write test.
• HDDRUTIL: The list of explicitly displayed partition types in the partitioning dialog has been extended.
• HDDRUTIL: Fixed Windows-compatible partitioning of media that before partitioning were in GPT format.
• HDDRUTIL: Support for partitioning with a GPT instead of a Master Boot Record (MBR) partition scheme.
• HDDRUTIL: With "Edit Partitions" the GUID for the type of a GPT partition can be modified. The partition GUID and the 36 character GPT partition name can be edited after double-clicking the partition type GUID. The Atari can only display 8 bit characters, but the actual codeset is a 16 bit codeset. Therefore, with names outside of the ASCII range (created by other platforms), 16 bit characters may get lost.
• HDDRUTIL: The partition GUID (not only the partition type GUID) is saved to the clipboard with "Partition->Export to Clipboard".
• HDDRUTIL: "Restore Root Sector" has been renamed to "Repair Partitions" and also repairs the GPT data, based on the GPT backup.
• HDDRUTIL: The compatibility settings for partitioning have been simplified.
• HDDRUTIL: The partition information exported to the clipboard has been extended.
• HDDRUTIL: Just like for Linux and Minix partitions, with "Devices and Partitions" you can also configure separately whether HDDRIVER reserves drive IDs for FAT32 partitions.
• HDDRUTIL: The "Help" buttons in the dialog windows have been removed. Each user of the full version of HDDRIVER 12 has an up to date manual as a PDF file, which provides a considerably better help.
• HDDRUTIL: Fixed a bug related to getting the Milan's boot parameters.
• HDDRUTIL:After formatting floppy disks (e.g. in a USB drive) a TOS-compatible filesystem is created automatically. There is no need anymore to partition with an empty partition table.
• HDDRUTIL: Two items were added to the "Windows" menu: "Cycle" and "Close". The respective keyboard shortcuts have always existed.
• HDDRUTIL: Numerous user interface improvements and optimizations.

The new release of SCSI2Pi among other things extends the functionality of the SCSI-to-USB bridge. With HDDRIVER and SCSI2Pi you can use USB drives without special USB hardware or USB drivers. This feature has been tested with a TT and a USB stick, a USB DVD drive and a USB floppy disk drive. HDDRIVER can boot from a USB drive, and with HDDRUTIL you can format floppy disks. USB drives can be mapped to drive A: or B:, e.g. in order to replace a broken floppy disk drive. Or you use USB sticks with MagiCMac (or MacOS), which was tested with a Performa630.
With a single external hardware an Atari (or another computer) has access to emulated hard drives, removable media drives, MO drives, CD-ROM/DVD drives, tape drives (streamers), printers, network adapters, USB drives and a realtime clock. Image files are simply copied to the Pi via the network and can be managed with the SCSI Control app, a web interface or on the command line (also remotely).
On the Atari SCSI2Pi is especially well supported with the SCSI2Pi client tools.
