hpt370 is a known problem controller...
- none of the onboard raid actually works right.
supported "hardware raid" chipsets
http://www.linux-ide.org/chipsets.html
- if you are using just 2 disks... sw raid is better than the
'broken" onboard raid
- Raid testing..
- disconnect one disk ...
- boot up -->> a properly configued raid1/5 system will always boot
- write multiple 2GB or 4GB sized files
- reconnect and reboot and watch it resync
- repeat for each disk

cable lenths of 18" is the max per specs ... but wonder why there is
24" and 36" lenghts ?? ( sometimes, depending on which controller, it has
no problem driving the extra load )
- dont mix ata-66 drives with ata-100 drives
- use only the Master on each ide cable
- dont mix a cdrom on the same cable as hard disks
