I have formatted the 8GB SD Card into four 2GB partitions and filled 3 of the partitions with samples/programs. Your K2000R/K2000RS must have OS 3.54 or OS 3.87 to be able to read 2GB. The OS versions before 3.54 could only read 1GB. Since this SD Card is already formatted to 2GB, make sure your OS is 3.54 or 3.87.
The OS version is shown briefly on the display when you turn the K2000R on. The K2000R can normally just use 2GB of a hard drive.
By configuring the Hard Drive Emulator Board as 4 SCSI ID numbers, the K2000 can access 8GB. The SCSI Emulator Board has no moving parts like a SCSI Hard Drive, so it's completely silent and should last forever. I have this exact model of SCSI Emulator Board in my K2000R and it works perfect. The SCSI Emulator Board has active termination and the SCSI ID#'s are set to ID# 2, 3, 4, and 5.I will change the SCSI ID#'s if you want different ID#'s, let me know before the package ships. If you have any external SCSI devices, the external device must be set to a different ID#, or you'll have an ID# conflict. Installation is simple and only takes 20 minutes.
