Hello Linux folkz, Is there any way to tune up SCSI HD parameters to make its transfer rate faster? I tuned up my WD IDE HD with hdparm like this. And it's running faster than SCSI HD. About 32.17 MB/sec IDE HD vs 21.15 MB/sec SCSI HD. What can be done to SCSI in this respect? Any ideas are greatly appreciated. Thanks in advance Alex # Turn on 32 bit transfers on the IDE Hard Drive echo "Turn on 32 bit transfers on the Hard Drive" /sbin/hdparm -c3 /dev/hda # Set sector count for filesystem read-ahead.
