Can somebody tell me what this means? panasonic external bd snow leopard, thanks for any replies

Error 'Scsi error - ILLEGAL REQUEST:INVALID COMMAND OPERATION CODE' occurred while issuing SCSI command 46020..00140 to device 'DASPI:IODASPIService:20f0e01aa2e31196:'

Please update to DASPI 1.2 if you haven't already. There is a known problem with SATA drives in USB enclosures with JMicron USB-SATA bridge chipset. Workaround will be added in a next version of MakeMKV.

Sorry should have stated this but forgot running makeMKV 1.6.5 daspi 1.2
