Richard Watson napsal(a):
Hi - I'm getting vastly different performance results on hda (master) as
opposed to hdb (slave). Basically when my root partition mounts (/dev/hdb)
I'm warned that DMA is off, yet hdparm -i shows udma as active. Basically
/dev/hdb performance sucks ... I've bought both drives in the last few
months. The motherboard is quite old (3 years .. I think).
Any suggestions would be appreciated.

Thanks - Richard

maybe they dont like each other, try to plug second hd to another
controller (hdc/hdd)
