Small loads/stores work, but SCSI2SD fails with large writes

This is often a sign that only one end of the SCSI bus is terminated.

The following applies to the pre-V5.0 boards ONLY. There is no "J3 TERMPWR" jumper required on the newer boards.

A common cause is the use of a DB25 connector. Pin 25 is supposed to provide power to run the terminator yet several samplers do not connect this pin. Close the jumper labelled "J3 TERMPWR" on the SCSI2SD to provide direct power to the terminators. (5V power must be provided via the Molex 4-pin connector for the jumper to work.)

Does SCSI2SD work with samplers ?

There are compatibility issues with the Akai MPC3000, most other samples should work ok.

Thanks to Carl at Precious Sound for putting in the time to test SCSI2SD.

Does SCSI2SD support 256 bytes-per-sector ? More than 512 bytes-per-sector ?

Yes, from firmware version 3.3, set via the scsi2sd-config utility.

Does SCSI2SD do ECC or mirroring ?

No. However, you can configure SCSI2SD as up to four devices and use whatever RAID, data duplication, striping, or mirroring capabilities your equipment supports.


What is scsi2sd-monitor ?

It is a manufacturing tool for verifying that a board is not defective. It must be used when the SCSI cable is DISCONNECTED. Use of this diagnostic tool is the only thing that causes SCSI2SD to issue a SCSI RESET.

Use scsi2sd-util for SCSI bus event monitoring and general debugging.
