It doesn't seem like it. Taken from Western Digital's specifications for the above drives: WD740ADFD -- http://wdc.custhelp.com/cgi-bin/wdc.cfg/php/enduser/std_adp.php?p_faqid=1405&p_created=1135201452 WD2000JD -- http://wdc.custhelp.com/cgi-bin/wdc.cfg/php/enduser/std_adp.php?p_faqid=1027&p_created=1056559256 Summary: WD740ADFD -- 10000rpm, 4.5ms seek, SATA150, 16MB cache WD2000JD -- 7200rpm, 8.9ms seek, SATA150, 8MB cache Neither of these drives have SATA300-capable controllers on them. Therefore, there is no problem. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
