Is there any know problems with this disk (Seagate 200gb/ata) + FreeBSD +
Promise/RAID0? Im asking, since a similar configuration but with smaller
disk works fine. I keep getting - after several hours of populating a huge
data base:

/kernel: ad4: hard error reading fsbn 0 (ad4 bn 0; cn 0 tn 0 sn 0) trying PIO 
mode
/kernel: ad4: hard error reading fsbn 0 (ad4 bn 0; cn 0 tn 0 sn 0) status=59 
error=10
/kernel: ar0: ERROR - array broken

why would the kernel want to read ad4 fsbn 0 (ad4 bn 0; cn 0 tn 0 sn 0)
when the filesystem is ar0? 

/kernel: ar0: 381564MB <ATA RAID0 array> [48642/255/63] status: READY subdisks:
/kernel: 0 READY ad4: 190782MB <ST3200822A> [387621/16/63] at ata2-master 
UDMA100
/kernel: 1 READY ad6: 190782MB <ST3200822A> [387621/16/63] at ata3-master 
UDMA100
