April 7, 2026: DISKUS 3.99.6 (German only) is available
There is a new version of the free mass storage tool DISKUS. DISKUS is the Swiss Army knife for working with floppy disks, hard drives, and memory cards. Thanks to SCSI Driver support, it can access any mass storage device (ACSI, SCSI, IDE/SATA/ATAPI, USB). For working with very large media, 64 bit sector numbers are supported. The manual contains many tips for recovering lost data.
March 26, 2026: SCSI Driver and firmware test suite 4.0 is available
There is a new version of the SCSI Driver and firmware test suite for testing SCSI Driver and firmware implementations based on the SCSI and SCSI Driver standards. The tests test software and device functions, not only with SCSI/ACSI but also with IDE, SATA, ATAPI and USB. They have already revealed numerous bugs, so that the respective developers could fix them. The tests can be started from the desktop, do not modify any data and are open source. Therefore, you can always see exactly what is tested and how. Please contact me if a test expects a result that is not compliant with the respective standard, so that this test can be updated.
January 9, 2026: Full-fledged hard disk drivers with bugfixes for EmuTOS
ETOS_FIX replaces the built-in EmuTOS hard disk driver with a full-fledged driver of your choice, e.g. HDDRIVER, CBHD, HuSHI, ICD or AHDI. Furthermore, ETOS_FIX resolves several long known EmuTOS bugs that are not present in the listed drivers. With ETOS_FIX and HDDRIVER you can enjoy many HDDRIVER features, high speed and a wide range of supported devices also with EmuTOS.
My suggestion from some time ago that EmuTOS should allow TOS-compliant booting of external drivers did not meet with approval. Maybe the EmuTOS developers will reconsider this and will give the user a free choice. Ideally, ETOS_FIX will become obsolete sooner or later.
