It's a smaller patch and > no need for any changes in SCSI. I have a confusion to this, can you please guide where exactly to look for this. Is there any existing solution to this problem? I did a lot of analysis and actually tried to make use of a number of USB HDD's from different vendors to be very sure of my observations. Our's is a target where-in we connect our HDD through the USB interface. Do you mean that putting code changes at this place would have impact on SATA HDD?

Again, if possible please share that code point, We can again check if that is hitting in our case. If need be I can provide the list of all the HDDs with their manufaturer ID's - on which we tested. Please let me know for this. > > James > > Thanks & Regards, Amit Sahrawat -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
