There's a good article on hdparm and its usage at http://linux.oreillynet.com/lpt/a/linux/2000/06/29/hdparm.html Mine went from /dev/hdb: Timing buffer-cache reads: 128 MB in 1.93 seconds = 66.32 MB/sec Timing buffered disk reads: 64 MB in 24.01 seconds = 2.67 MB/sec to /dev/hdb: Timing buffer-cache reads: 128 MB in 1.92 seconds = 66.67 MB/sec Timing buffered disk reads: 64 MB in 3.46 seconds = 18.50 MB/sec After a few minutes' tinkering. Have fun... Bill
