That's right; the SCSI sdparm doesn't seem to have an effect. Sending the same SCSI command via sg_utils or scsitools also doesn't. And...no word from the manufacturers. So, I think it's almost safe to say that the hardware doesn't support IDE [versions of] start/stop. "Almost", because it's still possible that it's somehow not getting the USB commands, because of something between the SCSI emulation and the physical USB layer. I'm going to dive into some libusb, and see what damage I can do. I'll report findings... -- ___________________________________________________ Play 100s of games for FREE! http://games.mail.com/ ------------------------------------------------------- Using Tomcat but need to do more?
