ZuluSCSI RP2040 and EMU E64: Unable to read or write drive

[lkamp]

Hello,

I have a RP2040 connected to a EMU E64 sampler. I have one disk image on the SD card (HD3.img). The E64 does recognize a drive with ID 3, but somehow can't read or write it. When I try to format the drive, the LED on the ZuluSCSI flashes for a while, but the behavior does not change.

I suspect there is something wrong with the communication, when I show the drive information on the E64 the drive name is gibberish, and all other values are reported as being zero.

Any input is welcome, thank you!

I added a picture of the information the E64 shows about the drive:

To close this discussion, the fault was hardware related. I got a new ZuluSCSI from my vendor and everything worked first try. Seems I just had bad luck and got a faulty ZuluSCSI.
