Hi,
How is the ultimate harddisk performance with UDMA66? Although it
works fine with UDMA66,but the harddisk performance is
just like UDMA33 as below. The question is how to improve
the speed up to 20M/sec or so. My mainboard is Abit BP6
with HPT366, harddisk is IBM-DJNA-351520.
Any suggestions will be most appreciated.
Regards,
Jun
