I had a similar problem with my HPT370A. I was trying to set up 1 RAID0 array of 4 drives (4x80GB). I was successful at getting 2 arrays of 2x80 to work. However, whenever I would create 1 4-disk array in the bios, create and format the partition, I would get ERRORS (ie. data written to the array was lost/scrambled upon read). I tried everything: ataraid, HPT's closed source driver, upgrading the board's HPT BIOS, assigning different IRQs to different IDE channels. Nothing worked, I was still getting errors. Someone from the mailing list suggested that there might be a 256GB cap for the board. I still do not know if there is such cap, as after contacting HPT and explaining my problem in details, I did not get any more answers. Anyway, I went with the Linux MD software RAID and to tell you the truth, I should have done it in the beginning. Best solution, by far. Got 1 array of 4x80GB. Speed is excellent as I am getting 95-100MB/sec (hdparm -t /dev/md1) throughput with about 25-35% CPU load (Athlon 1.2Ghz). Very stable as well, running for 90 days now on Redhat 7.3 2.4.18 kernel. Unless you need your array to be accessible under Windows, I would go with Linux MD. RAID5 is implemented, although I never tested it. >From my experience, the drivers provided from HPT are slow and buggy, ataraid drivers not very reliable (at least as of 2.4.18). Linux MD: fast, clean and stable. Hope this helps. MK > I just recently acquired a Highpoint RocketRAID 404 to replace my > ancient and much hated Promise Fasttrak 100 TX4.
