I have a pretty new motherboard (Abit IC7-MAX) that should be able to handle the larger than 137GB hard drives that need 48-bit addressing. I have 2 160GB ATA100 hard drives connected to a Highpoint RocketRaid100 card in RAID 0 configuration for 298GB (real GB) in disk space. I'm running XP with SP1 (which should be able to handle the greater than 137GB HD capacities, as I also have a 200GB ATA100 drive that is also installed and working). Initially, I was able to partition and format it for 298GB of disk space, and it had been working fine up to this past weekend. As I got to putting more and more files on the RAID 0 array, when I get to around 240GB, the RAID controller starts beeping, and it complains that one of the drives is not working. So I reboot, and the RAID 0 array is still intact, but if I add more files to it, I get the RAID controller beeping at me, and it complains that the other drive is not working. After I back up my data, I delete the RAID 0 array, and start over from scratch. I boot back up, have XP's disk manager create a large primary partition on the RAID 0 array, and then I format the partition with NTFS. The formatting gets to 86% and then it hangs (86% of 160GB is 137GB). That appears to me that I'm still hitting the 137GB wall in this RAID 0 array. What should I do to alleviate this situation.
