Re: sata to pata adapters on p4c800

I own 2 "RocketHead 100's" pata to sata adapters (connect pata hdd to
sata channels...). Although they work fine in single drive
configurations, I am not able to set-up a raid0 array with these
adapters. Have not tried raid1 with them, as it's not required for my
setup. Using maxtor ata 133's and my throughput is up only slightly at
best compared to the ide channel. Needless to say, the adapters sit in
my collection of interseting, yet fairly unused devices box...
FYI
