Introduction Description Suska GigaFile is a solid state disk, intended to work on Atari ACSI or SCSI interfaces. The physical memory SD cards are foreseen. In this way, the GigaFile is widely configurable using SDSC (cards with small capacity up to 2GiB), SDHC (cards with high capacity from 2GiB to 32 GiB) or SDXC (cards with capacities greater than or equal 32GiB). So this product should meet any individual requirements.
Compatibility Issues concerning SD Cards All SDSC, SDHC, SDXC cards, which can handle blocks of 512 Byte size, are suited for the operation in the GigaFile. Some SDSC cards with a capacity of more than 1GiB may not work properly. This behaviour is described in detail in the section Tricks and Limits. To verify if a card is suitable or not, it can for example be inserted into a card reader connected to a Windows PC. Open the formatting dialogue. There is a setting, 'Cluster Size'.
occur that some SD cards do not work properly. Reasons, therefore, may be incompatible supply voltage ranges or cards with block sizes different from 512 bytes. The supply voltage is 5V and is connected beside the ACSI and SCSI bus signals to the 26 position HDDSub header. To connect the GigaFile to the Atari ST or to any SCSI interfaces, use the respective cable adapters or one of the PCB adapters which are separately available at Inventronik GmbH.
of a complete data loss on the inserted card. If the user is not completely aware of the behaviour of the operating system in connection with the hard disk driver, it is strongly recommended to change the cards after the host has been shut down. Power Supply There are several possibilities to power the GigaFile. This mainly depends on the system to which it is connected. In principle there are the following three options: 1. Connected SuskaIIIC 2. Connected to a 19 pos. ACSI port. 3.
sometimes it seems that the SD cards or the GigaFile won't work correctly. The following things were found during intensive testing. 1. SDSC cards with block sizes greater 512Byte: Some SD cards seem not to handle blocks of 512 bytes. This does not conform to the SD card specification. Among these are, for example, 2GB SDSC cards. The SDSC specification reserves 12 Bit addresses and a maximum multiplication factor of 512. So there are a maximum of 2¹² * 512 = 2.097.152 blocks.

Cable Assembly SuskaIIICGigaFile The GigaFile is best fitted to SuskaIIIC. It is pluggable directly to the SuskaIIIC ACSI connector without the use of a cable. If a cable should be used, it is a 1:1 wired 26 pos. HDDSUB cable assembly with one end having a female connector, and the other end male. Cable Assembly SCSIGigaFile GigaFile 26 pos.

GigaFile for use in the Akai S950 Sampler This tutorial is written by Jamel Naitizgui in April 2013. The GigaFile is compatible with the Akai S950 (IB105 Hard Disk Board installed). How to get the GigaFile working with the Akai S950 Sampler: Important: only 2GB and 4GB SD cards are compatible. This is not a drawback because the S950 has a memory standard of 750kB which is expandable up to 2.25MB. Be aware, that 2GB cards may fail to work with the GigaFile.
Now two volumes are created on the SD card. Verify this with the "SLCT" option and proceed with step 5. On this screen you have now the choice between V1 and V2: *01 VOLUME SLCT , CREATE V1 (turn JOG control to select V2 ). *HD CONT 1 *HDRIVE 1 *RENAME 1 UNFM% Repeat step 6 every time you need to create volumes. A maximum of 128 volumes can be created on a SD card but around 70MB can be stored on a 2GB or 4GB SD card.
